BEUMER Group’s conveyor and ship loading solutions to be highlighted at MINExpo

BEUMER Group is planning to highlight just how conveying and loading systems enable safe, efficient and environmentally friendly handling of bulk materials at the upcoming MINExpo 2021 event in Las Vegas, USA.

The company’s overland conveyors and pipe conveyors enable mine operators to create individual routes for the transport of raw material with steep angles of inclination and narrow curve radii that are adapted to the respective task and topography, BEUMER says. When planning these systems, the system provider also relies on camera-equipped drones for planning, implementation and documentation. Using special software solutions, the engineers evaluate the aerial photographs photogrammetrically to generate digital terrain models.

The product range includes stackers and bridge reclaimers for storage yards, with or without blending bed systems. These reclaimers stack bulk material and guarantee a maximum blending effect, according to the company. Users can also efficiently homogenise large quantities of different bulk materials and bulk material qualities and, thus, ensure the uniformity of the raw materials used. For efficient loading, BEUMER Group also offers ship loaders with fixed booms and extendable telescopic belt conveyors. To supplement these, users can also procure bulk loading heads to use when loading bulk materials into silo vehicles quickly and without dust.

The company will present efficient system solutions with overland conveyors, pipe conveyors and ship loaders from September 13-15 at MINExpo.

PROK takes conveyor roller durability to a new level with HDPE solution

PROK has just released a new high-density polyethylene (HDPE) roller which, the company says, is lighter, more durable and avoids secondary conveyor damage in the event of a failure, reducing the unscheduled downtime that costs mining companies millions of dollars in lost productivity annually.

PROK Global Product and Engineering Manager, Ray Anderson, said the new roller was specifically designed for high speed and large tonnage applications where reliability was crucial.

“Conveyor rollers are a big cost and can cause huge risk to an operations output,” he said. “A mine or port facility with a large conveyor system will often need to replace several rollers in a day, and that requires a lot of maintenance manpower.

“If a traditional steel roller breaks it can damage the conveyor belt and the whole conveyor system can go offline, so the mining industry has been steadily moving towards lighter, more durable rollers made of advanced composite materials.

“Reliable rollers are crucial to maintaining production levels. If a conveyor stops due to roller failure, you start losing money.”

The global conveyor component manufacturer says it pioneered the use of lightweight HDPE material in conveyor rollers over 10 years ago searching for a solution that would not damage the conveyor belt in the event of failure, while reducing the risk of manual handling injuries when rollers were being installed or changed out.

Built on more than 18 months of research and development, its latest solution is state-of-the-art, taking low maintenance rollers to a whole new level, PROK said. Using a specially formulated reinforced polymer matrix, the lightweight, belt-friendly, wear-resistant roller has been created for heavy-duty applications.

Incorporating features to lower maintenance costs and a high-performance bearing housing to ensure there is no risk of end-cap walk over time, PROK HDPE delivers the reliability that can help mining companies increase production and improve safety, according to the company.

The HDPE rollers are made from a specifically engineered high-density polyethylene, which means they are suitable for corrosive environments. They also have a premium seal arrangement (with low friction properties to ensure low break away mass and run resistance during operation) and come in a range of sizes to suit a variety of mining operations and applications.

In what PROK claims to be a world first, the new HDPE roller also includes visual wear indicator technology to assist mining companies in improving their maintenance planning.

The original PROK yellow tube combines with a green inner layer to act as a visual wear indicator for maintenance teams so they can better plan their roller changeouts. This innovative feature will help customers to simplify idler maintenance and reduce costs, according to the company.

Martin Engineering goes autonomous with N2 Twist Tensioner for conveyor belts

Martin Engineering has introduced an autonomous tensioning system that, it says, continuously monitors and delivers proper cleaner tension on conveyor belts.

By using Martin Engineering’s new smart technology platform to maintain proper blade-to-belt pressure, the N2® Twist™ Tensioner provides the best possible cleaning performance throughout the life of the blade, according to the company. The system also alerts operators on the Martin Smart Device Manager App when the blade needs changing or if there is an abnormal condition.

“The result is efficient cleaning, increased safety, reduced labour and a lower cost of operation,” the company said.

Andrew Timmerman, Product Development Engineer at Martin Engineering, said the company designed the unit for heavy-duty applications and tested it outdoors in punishing environments and applications.

“The N2 Twist Tensioner has proven itself to be a rugged and highly effective way to maximise both cleaning efficiency and blade life,” he added.

Located on the head pulley, primary belt cleaners commonly have a twist, ratchet or spring tensioner to ensure the cleaner blade stays in consistent contact with the conveyor belt for proper cleaning and material discharge, Martin Engineering says. Prior to the new design, belt tensioners had to be monitored and adjusted manually, in some applications on a daily basis, so they would maintain optimum pressure and carryback removal. Estimating when blades needed changing was often a guessing game that, if left too long, could lead to belt damage, according to the company.

The company continued: “Inadequate tensioning causes carryback to cling to the belt and spill along its path, piling up under the conveyor and emitting excessive dust. This requires extra labour for clean-up and can affect air quality. Over-tensioning leads to friction damage to the carrying side of the belt, premature blade wear and potential splice damage. Both scenarios create unsafe work conditions and raise the cost of operation significantly.”

The N2 Twist Tensioner automatically maintains precise cleaning pressure throughout the entire life of the blade, without maintenance, Martin Engineering says. The tensioner applies the proper amount of torque to deliver optimum cleaning pressure at the blade tip, supporting the Constant Angle Radial Pressure cleaner design that, it says, withstands the force of heavy bulk cargo but retains a consistently tight seal across the belt profile.

Martin Engineering’s smart technology platform monitors blade wear and informs operators when the blade needs changing from control systems that are housed in a durable weather-resistant NEMA 4 control box. Experts recommend changing blades before there is a chance of detachment or a “pull through” (inversion under the head pulley). In the event of a premature pull through, operators are alerted, and the tensioner’s internal self-relieving coupling rolls over. A blade detachment also triggers an alert allowing operators to quickly shut down the system and avoid expensive belt damage.

The electrical system runs both the tensioning system and the sensors, with the unit powered by a rechargeable 12 v battery life. It can also be specified to run on 110-220 VAC.

Martin Engineering concluded: “The N2 Twist Tensioner and Smart Device Manager App ease the burden on managers and workers so they can focus their attention on other critical details of the operation. Precise tensioning and improved belt cleaning reduce the volume of dust and spillage from carryback, improving workplace safety and decreasing the labour needed to maintain and clean around the discharge zone.”

WCM’s Woodhouse Colliery met coal project heads for site work

West Cumbria Mining says the UK Government has agreed with Cumbria County Council’s decision to approve the planning application for its Woodhouse Colliery project in the northeast of England and has lifted its “holding direction”.

The decision means the company can make plans to commence site works later this year at the metallurgical coal project.

Cumbria County Council (CCC) Development Control and Regulation Committee, in October, resolved again to grant planning approval to West Cumbria Mining (WCM) to develop the project. This was the second such time the council had approved the project, following a formal approval back in March 2019.

Even with this approval in tow, the UK government could have stepped in to further scrutinise CCC’s sign off – a move they decided not to employ.

CEO Mark Kirkbride said on hearing the news: “I am delighted that the holding direction has been lifted following what has been an extremely rigorous planning process. My team and I are now looking forward to concluding planning signoff and then being able to commence preparatory steps to begin site work later this year.”

When the CCC approval was granted, WCM said it anticipated starting site work early in 2021 (before spring), with initial coal production commencing around 18 months from the start of construction.

Once the Woodhouse Colliery moves into the operational phase, the company plans to extract and process around 2.7 Mt/y of metallurgical coal from the operation, focused on supplying UK and international steelmaking plants.

Run-out and pocket extraction will be the chosen mining method at Woodhouse as this is a proven, highly versatile coal mining method that takes advantage of advancements in mining technology to mitigate risks associated with the Cumbrian Coal fields, the company says.

The technique includes the use of bolter miners to develop the gate roads for the panel, with a bolter miner then driving a run-out roadway. A continuous miner subsequently cuts chevron cut pockets into the pillars, while the roof is supported. Shuttle cars continuously move coal from the respective continuous miners to the feeder breaker and, once coal has passed through the feeder breaker, it falls onto the underground conveyor belt to be taken to surface.

Once processed, the coal at Woodhouse will be transported to the railway loading facility (RLF) in the Pow Beck Valley, near Mirehouse, via an underground conveyor buried in a concrete box culvert, which will mitigate any visual, noise or dust issues between the mine site and RLF, in recognition of the sensitivity of the area, WCM says.
