A roll crusher was installed as a primary crusher to crush rocks of 7.0 cm maximum size. The distance between the rolls was set at 1.5 cm, the diameter of the rolls was 110 cm and the width 100 cm. ... Mathematical and Physical Modelling of the Flat Rolling Process. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014.

A high-quality hammer crusher can keep final material passing a twenty mesh, fifty to sixty percent passing a fifty-mesh screen. Crusher hammers are high chrome content. The hammer service life depends on the material you process. If you're running abrasive quartz, they'll last somewhere between one to two weeks.

Abstract. Since for granulation processes the crusher operation has a decisive influence on the system stability, a reliable mathematical model to represent an industrial double-roll crusher of a urea granulation circuit is provided in this work. The crusher was described by the model given by Austin et al. [Austin L.G., Van Orden D.R., Perez J.W.

4. The 5-20mm material under the first and second vibrating screens is sent to 4 double-roll crushers through the belt conveyor and crushed to 0-5mm. The output from the twin roll crusher is sent to the third and fourth vibrating screens. Materials over 5mm are sieved and returned to the double-roll crusher for further processing.
