Currently Designing Crushing Equipments

Engineering organization C&E Engineering, which specialises in the refurbishment of jaw crushers and cone crushers, has developed a cone crusher that features half the amount of parts that a normal cone crusher would use, enabling the end-user to perform maintenance easily and cut downtime.

C&E Engineering technical manager and inventor Leon Venter says he designed the new cone crusher to be a low-profile and efficient machine for crushing chrome slag, gold, platinum and iron-ore and other materials. Venter says that years of experience in crushing equipment have helped him understand all the problems associated with crushers and led him to develop a new concept which eliminates a number of parts in the machine.

“The cone crushers that are currently available on the market are designed to host all the drives parts underneath the cone head, which puts it in the way of the crushed product. This causes wear and breakages, which are difficult to fix, resulting in significant and expensive downtime, and expensive warranty claims from the equipment supplier,” he explains.

The new crusher does not have shafts to break, sleeves to burn, gears to mesh or expensive hydraulic parts, which significantly reduces machine costs. The corporation currently hosts a range of designs, including the Mini Cone 250, which is aimed at laboratories. “The crusher is suitable for mining laboratories, as it is compact in size and relatively quiet,” Venter adds.

The firm built a prototype of an entry-level laboratory machine and started testing this machine in November. “We have had some significant interest from companies that build pilot plants at mines, as well as from significant miners, including Xstrata,” he says. The corporation has also carried out testwork with research institute Mintek. During testing, the machine crushed about 40 kg of gold and platinum ore with positive results. The proto- type crusher is able to process material feed size of 16 mm and is able to break it down to less than 1 mm.

By changing about four parts, Venter says, the machine can be converted for any appli- cation, including standard and heavy-duty machines as well as sand-making machines. Other advantages of the crusher are that the angle of throw and the path of the crushing head can be designed to suit any application, and the machine is 300 mm to 700 mm lower than existing crushers. No parts need to be accessed from the bottom of the crusher, often a difficult task on existing machines already built into plants, as all parts of the new prototype are accessible from the top.

Further, the drive design for the machine simplifies belt changes and does not need a lot of time for on-site commissioning, as there are no slide rails and alignment is not necessary. The organization is currently designing and building bigger models of the machine for use in mining operations.

As the professional manufacturer of complete sets of mining machinery, such as Sand maker,Magnetic drum separator, Henan Hongxing is always doing the best in products and service.
