Traditional designs of spiral would drums as used in the conveyor industry do not lend themselves to the arduous enclosed environment of the bucket elevator.
Further to this 4B Africa now offer drums specifically designed for both elevator head and elevator tail pulleys.
The drums can be supplied either crowned or parallel machined to optimise tracking, most are made with a slatted open design and supplied with cleaning cones to minimise build up.
Shafts and drums can be made in mild steel, alloy steel and stainless steel to customer requirements.
Pulleys can be supplied either plain, primed, finish painted or PTFE coated for very sticky applications.
