A reliable clutch solution was required for a ball mill at one of the world’s largest (and oldest) open pit copper mines located in Mexico. The clutch’s primary role on the dual-pinion, direct-drive geared mill is to provide smooth starts during mill startup.
A large copper mine operator in South Africa fitted non-genuine replacement friction discs in a large 34-inch Wichita Standard Ventilated Clutch with catastrophic consequences.
A metal forming facility had experienced a major problem on one of its bending brake presses. The air-tube holding plate of the clutch failed dramatically when a large piece of the steel plate cracked off. The resulting downtime was very costly for the high-volume production plant.
A leading global manufacturer of drilling rigs and oilfield equipment required a topdrive braking solution for a new 750-ton land-based rig. The brake provides dynamic emergency stopping and static holding of the topdrive during drilling operations. The brake needed to be ATEX-certified and had to accommodate high disengaged running speeds while providing a high torque capacity in a compact space envelope.
A Louisiana sugar refinery needed to install a new intermediate inclined conveyor to provide an infeed flow of sugar into the initial affination (cleaning/purifying) process. The facility’s team wanted to design a conveyor system that used less energy and created less wear on mechanical components (shafts, keyways, belt stretch) than their existing conveyors.
