Cement manufacturing -brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the …
The process control design changed with time from simple mechanical on–off systems to electronic distributed control systems with programmable logic controls at subsystem …
In June 1999, it was put in an automatic PID loop to control the cement fineness by adjusting the separator speed. Off-line QC. Before moving to on-line laser diffraction sizing, the plant would measure 5 g of cement every 4 hours in an air-permeability apparatus to estimate a Blaine number. Although the personnel try to be as precise as ...
The blaine predicted via KPCR has the required prediction accuracy necessary for use in ball mill control. Keywords: Cement Mill, Fineness, Soft-sensor, KPCA. 1. INTRODUCTION Cement ball mills are generally used to grind clinker from the cement kiln along with gypsum and suitable additives to produce a fine powder, that is …

Most cement plants have restrictions with regards to their finish cement temperature, which should in a lot of cases not exceed 160 F (71 DEG C). Since in most cases the feed temperature of clinker is higher than 220 F (104 DEG C) and a ball mill creates additional heat, because of its inefficiency, additional cooling is required.
