Both open and closed circuit crushing are employed. For close circuit the product is screened with a mesh size much less than the set. Fig. 6.4 is a typical set up where ore crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in open circuit followed by finer size reduction in a closed circuit by rollProcess model. Mass balance of the circuit (virtual silo) in Fig. 1 is given by (1) d m d t = ∑ i = 1 n q in i ( t) ∑ j = 1 k q out j ( t), where m is the mass of accumulated material, t is the time, q in i ( t) is the i th input mass flow, and q out j ( t) is the j th output mass flow.

To process the bauxite, the bauxite must be mined, crushed, and delivered to the refinery. The first step to reaching the refinery after mining the bauxite is crushing. The crushing circuit is defined by a series of variables and how those variables come together to affect each other. Those variables include the following:Open Circuit Crushing. In this sector on Secondary and Tertiary crushing, we will continue the practice of talking about different equipment, the work it does, and the effects of what I call operating variables.
