2 compartment cement mill
In our two-compartment cement mills, the first compartment (for coarse grinding) has a step lining suitable for large grinding media. It protects the shell while ensuring optimum lifting of the mill charge. In the second compartment (and also in our one-compartment cement mills) we use a corrugated lining designed to obtain the maximum power . get price. Industrial Solutions polysius ball ...
Cement Raw Mill (Wet) - Dual Compartment
Cement Raw Mill (Wet) – Dual Compartment Microphone Location: On these mills, the feed end microphone should be placed fairly close to the discharge end of the primary compartment. This is required because of “water” noise signals caused when the surface area presented by the coarse feed to absorb the water is very small. As a result the water flushes through the area before the rock is ...
Energy and exergy analyses for a cement ball mill …
01.05.2020 · For example, Atmaca and Kanglu performed the first and second laws analysis of a raw ball mill (RBM) in a cement factory to optimize the grinding process and decrease the consumption of electrical energy. The first and second laws efficiency and the electrical energy consumption of the RBM are specified to be 61.5%, 16.4% and 24.7 kWh/t, respectively. Also, they found the use of exterior hot ...

Mill shell is lined with lining plates to protect it from wear, high chrome steel liners are now commonly preferred to give longer life. Lifting liners are used to enhance impact in first compartment, where coarse grinding is dominated by impact. In second compartment which is longer in size (L>1.5D), classifying liners are used to ensure media classification along the length of mill with large size balls …
Cement Grinding Optimization - LinkedIn …
In order to produce the final product size, the length of second compartment is usually double that of the first compartment. Smaller grinding balls are also used in the second compartment. The efficiency of fine grinding in the second compartment is largely controlled by the size of grinding balls. Due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding …
Cement Mill Grinding Media - Page 1 of 1
01.11.2017 · In your first compartment the grinding is not related to surface area at all and it is related to weight and number of impacts. In the second compartment the grinding is related to pass of contact or length of circumference (see attachment). But you should figure the ball charge base on how it is grinding along the length of the compartment. As I said before charge 80% of the weight base on one …
Mill equipment · Christian Pfeiffer
For second grinding compartment or mono-chamber mills . The compact spiral lining is mostly used in mono-chamber mills, or mills with a long second grinding compartment. The large number of progressive activator plates means that the ball load is moved optimally. The plow plates increase the energy transfer once again, creating a certain moderate sorting effect for the grinding balls, which …
