The result is a clearly more efficient grinding process. Separation of the ball mill into two (or three) compartment using the intermediate diaphragm; ... In this way: There is no tension between the intermediate …

The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. ... as the name implies, is fitted with a discharge diaphragm or grates between the cylindrical shell of the mill and the discharge trunnion so that particles greater than the openings of the grate are not discharged ...

Closed-circuit ball mills have been operated for cement milling for decades [[7], [8], [9]].Fig. 1 shows the process flow of a closed-circuit, two-compartment cement ball mill. The closed-circuit operation helped to reduce overmilling of particles [10], resulting in lower specific power consumption [11] in comparison with open-circuit operation, where …

Correct material level whatever the ball charge, the slot size and the circulating load; Optimized grinding process; Minimum wear of the internal equipment; Many more solutions can be tailored to best support all of your grinding applications. Get in touch with our experts to find out more.

In this way: There is no tension between the intermediate diaphragm and the mill tube, the mill tube is stabilized, while at the same time, relative movements and deformations of the diaphragm are avoided; The structure of the intermediate diaphragm in the Monobloc ® version supports the mill tube and works against deformation

equipment is used, air-swept mills are optimally suited for grinding solid fuels, such as coal or petcoke. Single-compartment mills are of a similar design to air-swept mills, but the material is discharged mechanically by a discharge diaphragm. These mills are well-suited for finer feed materials.

Two-compartment ball mills are widely applied grinding mills in cement grinding circuits (Genç, 2008). In this study, effect of HPGR pre-grinding and two-compartment ball mill intermediate diaphragm middle grate design on grinding capacity of a conventional two-compartment ball mill air classifier closed circuit was evaluated.
