A distinct class of roll crushers is referred to as 'sizers.' These are more heavily constructed units with slower rotation, and direct drive of the rolls rather than belt drives. They have a lower profile, allowing material to be easily fed by loaders, and are a good choice for portable crushers at the mine that reduce the coal in size for conveying to the preparation plant.
Roll rotation speed is adjustable for different waste conditions. (high or low) when the roll is overloaded or the unable material was detected, the conveyer automatically reverse the roll drive. Primary belt conveyer The belt conveyer system uses long lasting, durable …
