Size Reduction Equipment

2018-11-15  The work required for crushing a given mass of material is constant for a given reduction ratio irrespective of the initial size. Reduction ratio is the ratio of the initial particle size to final particle size. 𝑊𝐾= I = T 𝑖 𝑖 𝑊𝐾= I =𝐾𝐾 H J 𝑠 𝑠𝑝 •KK is called the Kick’s Constant

Crushing Vs Grinding Minerallurgy

For crushing no grinding media is required, the ore size is reduced by external forces applied by the crusher. Dry crushing but wet grinding. Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling.

2020-6-3  The crushing rolls are driven individually and directly by means of electro-motors or with coupling and gears, counterrotating via V-belts.The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between

Enduron HPGR High Pressure Grinding Roll First choice

2019-6-28  HPGRs consist of two rolls that are identical in dimension, rotating in opposite direction at the same speed. The main grinding action is a result of inter-particle crushing. Extreme pressure causes the particles inside the compacted material bed to fracture into finer particles and also causes microfracturing at the grain size level.
