for is 120mm, width, W, of each roll is 150mm, and the maximum roll gap, l, is 5mm. 2.1.3 Maximum Size of the Particle that can be Fed into the Roll Crusher The maximum size of the particle that can be fed into the roll crusher is determined by the radius of the roll R, roll gap, L and the angle of nip . From Equation (3), the maximum size of ...

The size of the rolls in a roll crusher is the biggest factor in determining the machine's throughput, with larger rolls providing greater throughput. However, throughput is not the only factor, and rolls can be too wide.

In the primary crusher, a conveyable product (<300 mm) can be produced from the raw materials with a maximum edge length of 2.0 m in one-step. In the following crushing stages, the required target grain size can be produced in the secondary or tertiary sizer.

Roll crusher, as one of the most economical and practical crushers, is designed to handle the first and second crushing of friable minerals and stones such as coal, clay, coal gangue, limestone, slag, cement clinkers, and shale, etc.

Width. 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 ...

The theoretical capacity of the roll crusher is the weight of a ribbon of feed having a width equal to the breadth of the rolls, thickness equal to the gap between the rolls and length equal to the peripheral velocity of the rolls in linear units.
