Roll crushers are a type of compression crusher mostly used in heavy-duty industrial/aggregate applications. Roll crushers were once very popular in the mining industry, where they were used to reduce excess rocks, ores, and other materials. A roll crusher uses two or more cylinders or drums which are connected to horizontal shafts that rotate in opposite directions pulling material through the crusher. The material you wish to grind or crush passes through the cylinders creating a finer and smaller product. The compression and opposite rotation of the two cylinders create the force and friction necessary to break the material passing through.
Jaw Crushers are mainly used in mining applications for grinding and crushing ores and rocks, but are not limited to the mining industry. Using compression methods, jaw crushers can handle and reduce many large-sized materials. The jaw crusher uses a stationary jaw plate and a moving jaw plate to create a unique “V” shape. As materials pass through the machine, the moving jaw compresses and pushes the material against the stationary plate. This considerable amount of force then crushes the material down to the desired size before it can pass through the bottom of the Jaw Crusher.
