Roller crusher is widely used in solid and block material pulverizing. Roll gap between the rollers is usually adjusted to satisfy the particle size of output material.

The roller revolves at low speed and breaks the incoming material against the surface of the roller. Depending on the type of roller crusher, the roller may have a smooth, corrugated, or toothed surface to facilitate the crushing process. The components of a single roller crusher include the roller, frame, bearings, and a driving mechanism. The ...

The width of the crusher must also be considered when taking into account the feed size. Selecting a crusher that is too narrow compared to the size of the incoming feed can result in the bridging of the feed material across the crusher opening. When this occurs, once again, throughput capacity is diminished and plugging of the chutes can occur.

Roller Inspections; Frequency: Inspect rollers monthly or as needed. What to Check: Ensure rollers are free of debris, spinning freely, and not showing signs of excessive wear or damage. Benefits: Well-maintained rollers reduce belt friction and wear, improving overall efficiency. Pulley Maintenance; Frequency: Inspect pulleys monthly or as needed.

HPGR (high pressure grinding rollers), roll/roller crushers, or mineral sizers use two large rollers or a roller and a flat surface. The rolls can be serrated, toothed, or smooth. Vertical impactors use the weight and friction of the feed (autonomous) or add hammer-like processors. Horizontal shaft impactors spin feed against various surfaces.
