However, bearings can have a nylon or polyamide retainer which can limit the upper temperature to 100°C - 120°C depending on material. Bearing shields will cope with the same temperatures as the rings and balls but rubber seals should not be used above 110°C. The next limiting factor can be the lubricant.

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

Nov 14, 2018· Basically, they support the weight of the shaft and provide a non-damaging surface to the high-speed shaft that rotates. The lining of a bearing is bonded with Babbitt, which is a soft alloy featuring a low-melting point. When contamination occurs or failure happens in the lubrication system, the softer alloy wears out instead of the shaft.
