Industrial consumables and engineering firm Bearing Man Group (BMG) reports that equipment manufacturer Oscillating Systems Technology’s (OST’s) range of materials handling, screen and transmission products includes a cost-efficient spillage solution, designed to prevent production losses during materials handling in the mining sector.
“This system, which encompasses various products that operate together to form a single efficient system, has important benefits over conventional systems, which are labour inten- sive, costly to operate and require additional equipment,” says OST Africa’s GM Deon Crous.
He explains that the advantages of the OST system include simple installation, modular components for extended service life of the system, reduced maintenance and a low-cost solution to spillage problems.
The OST spillage system consists of a dynamic impact bed, a high-impact torsion (HIT) system, a skirt clamp and skirt wing, impact zone panels, chute vibrators, duff feeders, primary and secondary belt scrapers and a bias plough.
The dynamic impact bed is a shock-absorbing trough, which is mounted underneath a conveyor belt. It is installed at transfer points where fine or coarse heavy material is being transferred and where there is a build-up of materials in the transfer chute. The HIT system combines a heavy-duty idler frame with an HIT arm system to absorb the impact of material that falls onto the belt.
The skirt clamp, which is the conveyor system’s spillage controller, ensures that positive pressure is always applied to the side wall. The skirt wing is designed to support a conveyor belt between the idler and frames when sagging occurs, in order to prevent overflow spillage.
The OST impact zone panels are used at high impact points in transfer chutes that are continually put under high stress and, therefore, have the highest maintenance requirements. This impact zone panel absorbs impacts and high wear resistant liners ensure efficient operation and an extended service life.
Chute vibrators prevent material blockages in a chute. Duff feeders, which accommodate the removal of dry or wet material from underneath belt scrapers down to collection points, also allow access for easy maintenance of conveyor rollers and belt scrapers.
The primary belt scraper blade tip is kept in contact with the belt surface, while the secondary belt scraper is segmented from all scraper components, for extended service life. The bias plough prevents duff that remains on the belt from damaging the return pulley.
OST’s materials handling product portfolio also includes the grizzly feeder system, which is custom-made to suit each application. This mobile feeder system, which constantly controls the feed of product onto conveyor belts at a rate of up to 80 t/h, can be quickly and easily dismantled and relocated when necessary. This system ensures optimum production, reduced wear and maintenance and is also designed to prevent spillage.
Electrical panels for these feeders are fitted with manual and automatic switches, frequency inverters, overload switches, flexible vibration cables and a step-down transformer.
OST bulk handling systems are available in Southern Africa from BMG’s network of over 100 branches. These systems are supported by specialised design and installation teams that guarantee these custom-built systems meet exact requirements in any application.
