1) The pre-crushing uses a crusher to crush the clinker before grinding, which can reduce the diameter of clinker particle to 5 ~ 8mm. 2) The pre-grinding adds a roller press to the cement grinding system. In this system, the clinker is extruded circularly, dispersed and separated, and becomes powder with diameter less than 2 mm;
In cement grinding process, although the specific surface area needs to be measured every once in a while, it has no close correlation with the cement strength and cannot reflect the distribution of cement particles. Therefore, the specific surface area of cement shall not be used as the single factor on quality control of cement milling.

A concrete grinder generally contains a rotating head that is used to smooth and level the concrete surface. Nowadays, the use of such tools is growing rapidly, most of the concrete grinding is done by diamonds. This process is known as "diamond grinding" as the abrasive discs utilized to grind the surface contain diamond particles.
Reducing the effects of inter-particle attraction forces of cement grains helps to keep particles from clumping together. This reduces void filling and improves the dispersion of the feed to the separator, both of which lead to enhanced grinding efficiency. For further advice, contact a cement production specialist.
