TW Woods Constructions  has developed a new smooth flowing low-height transfer chute that overcomes space, spillage and conveyor bulking problems common in coal mining and coal handling facilities.
Featuring a tough hardened steel construction, the coal transfer chute’s design is based on the company’s 40-year experience in constructing plants for mining, energy, construction and materials handling throughout Australia. TW Woods’ products for mineshaft development include shaft liners, drilling tooling and wear plate materials as well as custom-fabricated wear plate kits for the maintenance of heavy machinery used in shaft development, and bulldozers, trucks, graders and loaders.
The low-height coal transfer chute features a conical head developed by mining specialist designers to maintain high volume, high flow rates (up to 2000 tons an hour) when conveyors change direction either underground or on the surface.
According to TW Woods Director Mr Tom Woods, coal conveyors in underground mines have to frequently deal with 90-degree turns as they emerge from one shaft and transfer into another within very tight spaces. It is usually very difficult to get coal to turn that quickly without spillage and bulking up on the conveyor belts as coal is dropped from the belt above onto the one below while changing direction.
The new coal transfer chutes are designed to overcome two primary problems:

  • The compact design can be fitted into lower overall heights than conventional designs, operating with a separation distance between belts of 1200-1500mm
  • The chutes’ conical head is configured to provide a smooth transition through the turn for coal moving at typically 3m a second and dropping up to 1500mm onto a belt below
The coal transfer chute design draws upon TW Woods’ mining industry experience to eliminate the spills, splatters and bulking that can disrupt production in mines. The transfer chute has also been engineered at the company’s own extensive metal working facilities to easily outlast conventional designs and far exceed typical warranties.
