BMG’s cost efficient spillage system, which is designed to prevent production losses during materials handling, encompasses various products that operate together to form one highly efficient system. This system has important benefits over conventional systems, which are labour intensive and costly to operate, and require additional equipment.
“Spillage at feed and transfer points can exacerbate other problems on conveyor systems. These difficulties include belt wear, buildup of material on idlers, increased manual labour requirements for cleaning, belt tracking issues and shortened conveyor product life,” says Donovan Scott, manager of materials handling. “Coupled with these issues is the incorrect selection of products, which can be extremely expensive in terms of production costs. Conveyor efficiencies certainly have a huge part to play in bottom line improvements.”
BMG’s materials handling division offers a comprehensive range of products which are tried and tested in the local market. They deal efficiently with material spillage in diverse industries, including mining, quarrying, manufacturing and general engineering. Total cost of ownership is lowered through the selection and installation of these quality products, which are supported by BMG’s maintenance and repair service. Advantages of BMG’s spillage system include simple installation, modular components for extended service life of the system, reduced maintenance and a low cost solution to spillage problems.
The 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 course 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 a high impact torsion arm system to absorb the impact of material which 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 over-flow spillage.
Impact zone panels are used at high impact points in transfer chutes which are continually put under high stress and therefore have the highest maintenance requirements. This impact zone panel absorbs impacts, while high wear resistant liners ensure efficient operation and extended service life. Chute vibrators prevent material blockage 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 positive 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.
BMG’s materials handling product portfolio also includes the Grizzley feeder system (GFS) 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 tons per hour, can be quickly and easily dismantled and relocated when necessary. This system, which ensures optimum production, reduced wear and low maintenance, is also designed for no 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. BMG’s bulk handling systems are available in southern Africa from BMG’s network of over 120 branches. These systems are supported by specialised design and installation teams which ensure these custom built systems meet exact requirements in any application.
