A variety of models: Find roll breakers at Foeth
Roll breakers were traditionally used to reduce the sizes of materials to fine particles in the mining industry. They are used for heavy-impact applications and the processing of brittle materials like clean coal and salt or crushing wet and sticky materials like bauxite and clay. The crushers use single impact forces from a rotating roll equipped with teeth. They crush the particles against a stationary crushing plate, reducing feed sizes. If you are searching for double or single-roll breakers, Foeth provides a collection of machines. The crushers are mechanically tested to ensure durability. Talk to our experts for guidance on the best breakers for your industrial processes, and get value for your money by buying used machines.

How does a double roll crusher work?
Roll crushers are used for secondary or fine crushing in the chemical or mining industry. They can crush materials of medium hardness like rocks, lump coal, mineral slag and fireproof materials. A double roll breaker has a pair of rotating rolls in opposite directions, while the single crusher has one rotating roll and crushes particles with a single impact force. A crusher has two cylinders with a steel or ceramic finish. A hopper above the roller drops the materials into the gap between the cylinders rotating in opposite directions. The friction between the steel cylinders crushes the materials before they fall into the collection bin. You must set the space between the roller to match the desired particle size. The surface of the roll cylinders can be textured or smooth, depending on the application. Hard materials require textured cylinders for the effective breaking of particles.
Factors to consider when choosing a lump roll breaker
When selecting a roll crusher for industrial application, it is important to remember all the crushing process components. The materials to be crushed plays a major role in proper machine selection. Consider the friability of the material, hardness in compressive strength and moisture or abrasiveness. If the material is hard, special consideration should be given to the drive crusher design for effectively crushing the particles. Ensure the feed size is suitable for the materials you are crushing. The roll breaker diameter determines the angle of the nip and the ability of the crusher to grab the feed material into the crushing zone. The required product size determines whether you need multiple crushing stages to produce finer particles.
