To maximize efficiency and safety in mining operations, it is crucial to understand the essential equipment used in Australian mines. This blog post will provide an overview of various types of mining equipment and their applications, highlighting the top 10 pieces of machinery that are indispensable in both surface and underground mining operations.

Surface Mining Equipment

Surface mining, also known as open-pit mining, involves the extraction of minerals and resources from the earth’s surface. This method is often employed when mineral deposits are located near the surface or when the overburden, the material covering the deposit, is relatively thin. Some of the most common surface mining equipment includes draglines, excavators, shovels, and wheel loaders.

Draglines

Draglines are large, crane-like machines equipped with a bucket suspended from a long boom. These powerful machines are used to remove overburden and expose the underlying mineral deposit. The bucket is lowered to the ground, filled with material, and then lifted and swung to the dumping location. Draglines are highly efficient and can move vast amounts of material in a relatively short period, making them indispensable in surface mining operations.

Excavators

Excavators are versatile machines used for a variety of tasks in mining operations, such as digging, trenching, and material handling. These machines consist of a boom, stick, and bucket mounted on a rotating platform. Excavators come in various sizes, with larger models being suitable for heavy-duty tasks like stripping overburden or loading haul trucks. In addition to their versatility, excavators offer excellent precision and control, making them a popular choice for mining operations.

Shovels

Shovels, also known as power shovels or hydraulic shovels, are heavy-duty machines used to dig and load material in surface mining operations. These machines are equipped with a large bucket and powerful hydraulics, allowing them to handle heavy loads and break through hard materials. Shovels are typically used in conjunction with haul trucks, loading the trucks with the extracted material for transportation to processing facilities.

Wheel Loaders

How to Optimise Energy Efficiency in Conveyor Operations?

In the current fast-paced atmosphere of business, manufacturers are turning to new, innovative technologies to automate crucial production and material handling processes since organisations will constantly seek new methods to reduce corporate expenses and boost their bottom lines. This is why it isn’t surprising that many manufacturers are turning to conveyor belts in their production process. By automating manual production processes, conveyor belt systems help factories save time, effort, and resources. However, there are several techniques to reduce conveyors’ energy use and waste production.

In this article, we will be going over how you can be able to optimise the energy efficiency of your conveyor systems to be able to save time, energy and resources. 

How to reduce energy use of conveyor systems?

Here we have listed down the proper methods and precautions you should keep in mind if you wish to increase the efficiency of your conveyor system:

  • Observe proper maintenance

This is a crucial point that is often overlooked. Conveyor systems are frequently not maintained adequately because they are expected to operate indefinitely with no issues. As long as everything runs well, nobody gives them a second thought. However, it has been possible to keep a conveyor functioning at peak efficiency for many years. Yes, energy-efficient motors and driving units are essential. However, if the conveyor chain or belt is not correctly maintained, you may waste energy due to increased friction in the system.

Numerous conveyors use pneumatically-operated stop gates, positioning units, and other product-control accessories, so inefficiencies might result if the pneumatic system is not adequately maintained. As do the majority of conveyor manufacturers, we advise a yearly or biannual inspection or tune-up. A rapid, expert examination of the system under operating conditions can reveal worn parts that require replacement, chances for process optimisation, and other possible dangers, such as system overloading.

  • Selecting the most productive type of conveyor system

When choosing the optimal conveyor type to integrate into a production process, efficiency is the most critical element. Ultimately, better efficiency will increase production, productivity, and profitability while reducing time, energy, and material waste. Choosing the optimal conveyor for batch or continuous processing applications is not as straightforward as it may appear. It demands a variety of rigorous considerations, including its rate, layout, safety requirements, material characteristics, installation speed or transportability needs, and hygienic or sanitary conditions. Each of these characteristics aids in identifying the most efficient piece of equipment for a specific application and avoiding circumstances where an excessive amount of linked horsepower is unnecessary.

  • Choosing a conveyor that doesn’t need dust collectors

Eliminating the need for an additional dust collecting system is a further indirect energy saving that results from selecting the proper conveying system. Dust collecting systems frequently employ expensive blowers or compressed air to filter and remove particulate matter from the air and industrial environment. By choosing a fully enclosed mechanical conveyor as opposed to a pneumatic system, many external dust collector systems can be completely eliminated, saving a significant amount of energy, reducing maintenance, and removing some of the safety concerns typically associated with combustible dust bags used in dust collection systems.

  • Monitor your conveyor and check if any component is wasting energy

In the majority of power-and-free conveyors, the belt or chain is continually powered. Nonetheless, this feature of pallet-based conveyor systems enables the delivery of work, i.e., pallets with mounted products, to workstations on demand. As long as the individual work processes at each station are adjusted, this yields the best possible cycle time for product assembly. Choose conveyors with low-friction curves or drives that allow you to utilise fewer of them for a given length of loaded conveyor to optimise energy consumption.

However, optimising product throughput per hour is the most crucial component in avoiding wasted energy and resources. In other words, you will waste energy if your assembly employees hang around waiting for parts to arrive or if your automated stations require extensive maintenance downtime. Therefore, optimising each assembly process by time and motion studies can substantially affect energy consumption.

Regarding conveyor system components, pneumatic systems are frequently the most wasteful in terms of energy. As is the case with manufacturing facilities in general, pneumatic systems within conveyor assemblies can be inefficient or leaky, resulting in avoidable annual energy costs of thousands of dollars. A comprehensive assessment of pneumatic components and systems can result in substantial cost reductions and help keep your conveyer energy efficient.

  • Avoid overloading your conveyor system

If you overload a component of the conveyor or the entire system, you will be wasting more energy than you need. You will also increase the wear on the moving parts, such as the belts or chains, pallet wear strips, gearbox and drive unit pulleys or sprockets. Therefore, overloading a conveyor is never a good idea, even if energy consumption is unimportant. Examine the load by compiling a list of all the items that will be placed on the conveyor belt system and taking into account their shape and form, dimensions, orientation, and position on the conveyor. All of these factors must be taken into account beforehand to ensure smooth, uninterrupted operations.

  • Consider the installation of a variable frequency drive

Running a motor with advanced equipment controls, which receive and interpret information from the motors and allow the controls to regulate the motors based on real-time production requirements, is another method for conserving energy and resources. Many conventional conveyor systems only offer two modes: on and off. When the conveyor is powered on, it will operate at maximum speed regardless of the production condition. This is remedied by a variable frequency drive (VFD), which regulates the conveyor’s speed and changes it to match production needs in real-time.

Internally varying the voltage and frequency of the alternating current driving their motors, variable frequency drives conserve energy over time.VFDs can significantly lower the energy consumption of a motor system by allowing dynamic adaptation of motor speed to fluctuating load needs. In addition to improving a system’s power factor (PF), VFDs offer additional advantages, such as soft-starting and overclocking capability. VFDs permit electric motors to work at lower speeds, so conserving energy. This can increase the motor’s overall lifespan and provide a more substantial long-term investment return, justifying the higher up-front costs.

Bottom line

Every business model requires the incorporation of new technologies and enhancements into the manufacturing process on a consistent basis. Increased efficiency of a manufacturer’s conveying process, which historically accounts for a significant portion of a production floor’s energy expenditures, will affect a company’s total bottom line and ability to compete in the ever-expanding marketplace, which is essential to its continued success. We hope that the suggestions and recommendations we have given you above will be able to assist you in saving resources and energy when using your conveyor systems.

What are the Preventive Maintenance Check Points of Conveyors?

For a majority of manufacturers, conveyors are an integral aspect of their entire operation. They play a crucial part in the production process and material handling. Working with a practical conveyor system increases efficiency and promotes a safer workplace. When this system fails to function, production and business operations cease. The best way to avoid this is to keep up with your maintenance duties. Preventive maintenance will save you money on repairs and replacement components while minimising downtime. Therefore, your conveyor system must undergo routine monthly maintenance and inspection to detect any faults or miscalibrations. 

In this article, we will be going over the preventive maintenance checkpoints of conveyors so you may adequately maintain them to avoid wasted production time and resources.

What is the importance of consistent conveyor maintenance?

The significance of conveyors in the manufacturing process is incontestable. Nevertheless, we frequently operate as if the proper operation of conveyors is a given. We only perform maintenance work when there is an issue. Conveyor systems are designed to work around the clock and include many moving parts dispersed over a vast area, which is the primary cause of the lack of maintenance. For extensive maintenance, the entire conveyor system must be shut down.

Often, this necessitates the suspension of some or all production operations. Unfortunately, this maintenance delay frequently causes problems in the future. Minor issues accumulate and lead to catastrophic, costly failures that could have been avoided. Regular conveyor maintenance should, therefore, never be neglected. It must be planned and scheduled as part of routine plant operations. It is the only approach to minimise planned downtime for maintenance activities and lessen the likelihood of extended downtime due to a breakdown.

Basics of conveyor maintenance

Understanding the equipment used in your conveyor system is the first step in ensuring conveyor safety. Answering the following questions will allow you to anticipate the required maintenance chores associated with your prefered cleanroom conveyor system.

  • How often will system maintenance and repairs be required?
  • How detailed are inspections and repairs?
  • What components or tools are necessary for conveyor maintenance and cleaning?

Consider every conveyor component, including the high-performance chain, belt, and track. Are replacement parts for each component easily accessible? Consider that decreased availability of replacement components could result in production halts or delays for your company. As you progress through this article, bear in mind that routine maintenance can help prevent the following major conveyor issues:

  • Belt Mistracking: This issue happens when a mining conveyor belt pulls to one side and deviates from its intended path. Conveyor belts must follow a predetermined route. Most of the time, the track is a straight path. Any misalignment of conveyor belts might result in side-to-side movement of the belts. This will cause the conveyor belt to deteriorate. This severe issue can cause damage to other components, belt damage, and material spilling.
  • Belt Slippage: Materials being carried on a conveyor system may accidentally fall off or spill into the mechanism of the conveyor. Material spillage frequently happens at the intersections of conveyor belts. Mining conveyor belts require exact tension to prevent slipping. The conveyor belt will slip off the pulleys if overloaded or underloaded. Belt slippage can cause motor or belt failure. According to the manufacturer’s requirements, tighten your belts. Some factories take additional design precautions to prevent this substance from escaping. If the spillage is recurrent, you must evaluate the conveyor system for anomalies or flaws that could be causing it. 
  • Debris: Various materials are transported by conveyor systems almost each and every day. The materials being handled and moved around may leave debris of all sizes behind. The surroundings of the conveyor system also add to the accumulation of trash, which can eventually make its way to the conveyor mechanism. This can result in damaging clogs, impeding the functionality of conveyor systems. Regular cleanups are required to avoid such an anticipated issue. Debris accumulation should be inspected as part of your usual maintenance procedures.

Different conveyor components you should adjust or replace

Replace worn-out or malfunctioning components equipment as needed to prevent further damage. The items listed below are the components you should be observing.

  • Scrapers: High-performance scrapers will endure significantly longer than those of inferior quality. As necessary, replace scrapers that are faulty or worn.
  • Idlers: Examine your idlers and replace them if necessary.
  • Belt repairs: Repair any rips in the belt in accordance with the handbook. Please do not attempt to close tears with mechanical fasteners since they are only a temporary solution.
  • Rollers and idlers: During your monthly or weekly inspections, repair or replace any broken or damaged idlers or rollers.
  • Dust containment system: During your monthly or weekly inspections, repair or replace any faulty components of the dust containment system.
  • Replace lagging: Pulley lagging is the layer of material adhered to the shell of a conveyor pulley. Its purpose is to safeguard the cover, increase friction with the conveyor belt, and expel water from the pulley. Replace this part approximately every three to five years, unless ceramic

Checklist for the proper maintenance of a conveyor

Adhering to a consistent maintenance routine can reduce unplanned downtime. A conveyor manufacturer’s maintenance checklist details all conveyor components that require periodic examination.

  • Weekly maintenance

The motor, belt lacing, and drive chain are included in the conveyor’s weekly inspections. Using a laser temperature gun, the motor’s operating temperature is measured. The motor’s condition can be determined by comparing the operating temperature to a baseline. The maintenance checklist also visually examines the conveyor belt’s lacings and chain. Both should be tensioned and tracked accurately. Utilise a high-quality mineral or synthetic oil to lubricate the chain.

  • Monthly maintenance

The monthly conveyor inspection checklist is the most exhaustive. The drive motor, motor mounting bolts, gearbox, bearings, and v-belts are among the components that must be visually inspected for evidence of abnormal operation. Any abnormal vibration or sound must be addressed immediately to prevent a future breakdown. Adjust the tracking of the drive chain and conveyor belt. Make any required modifications to both.

  • Quarterly maintenance

An overall structural security inspection and lube are part of the quarterly checklist. Examine the entire length of the conveyor structure for signs of damage or loose hardware. Specific areas to inspect include the bearings and bearing mounting bolts. Inspect the head and tail pulley set screws and mounting hardware. Replace missing hardware and repair damage before resuming conveyor operation. Lubricate the bearings along the entire length of the conveyor with grease or oil—depending on the type of bearings and the manufacturer’s recommendations.

Bottom line

Consistent proper maintenance on a conveyor can significantly increase its productivity and lifespan, but not all models are constructed from high-quality materials. The guide we have provided above will enable you to undertake routine maintenance on your conveyor system. Consider that the material transported by your conveyor may impact the suggested maintenance plan. A malfunctioning conveyor can frequently halt all operations until repairs are made—a malfunctioning conveyor results in enormous costs. Adhering to a thorough maintenance routine can reduce unplanned downtime and wasted resources.
