As one of leaders of cement blaine versus closed circuit productivity industry, SBM always seeks innovation & excellence.
Cement grinding is the process by which cement raw materials are reduced in size inside a mill. The various types of mills used in grinding (particle size reduction) include the roller mill, rod mill and the ball mill. Ball mills are most commonly used in cement milling. A ball mill can operate either on open circuit or closed circuit. In a

The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closed-circuit tube mill operating at ...

Assessing cement fineness. In the past, cement producers gauged cement fineness (i.e., cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill.

re BLAINE AND POWER AND TPH RELATIONSHIP. Please show us the formulas you are talking about. Also try to explain your question in more detail, and maybe provide some numerical data for clarity. Otherwise, I must say that, in closed circuit, it is not a bad approximation to assume that power consumption is proportional to the specific surface.

The process had a closed-circuit HPRM system producing an intermediate product upstream of a conventional closed-circuit ball mill system that produced a final cement product of 3200 cm 2 /g Blaine fineness at a throughput of 192.7 t/h. The specific energy consumption for the major equipment of the combined process was reported to be 22.2 kWh/t.
