What is the harm of clinker grinding specific surface area exceeding 500?

The harm of clinker grinding specific surface area exceeding 500 is that the production process is difficult to control, energy consumption increases and the performance of cement products decreases.

1, the production process is difficult to control: when the specific surface area of clinker grinding is too large, clinker powder is easy to agglomerate and accumulate, and the production process is difficult to control easily, which leads to the decline of production efficiency and affects product quality.

2. Increased energy consumption: In order to meet the demand of clinker powder with higher specific surface area, it is necessary to grind clinker more times, which will lead to a lot of energy consumption and higher production cost.

3. The performance of cement products declines: the quality of cement produced may be affected. Excessive grinding of clinker particles will lead to changes in its chemical composition and crystal morphology.

In the process of cement production, the specific surface area of clinker grinding must be controlled to ensure the quality and efficiency of cement production. The conventional practice is to control the clinker grinding by adjusting the rotating speed of the clinker grinding, the position of the inlet and outlet of the grinding, adding a proper amount of grinding stones and changing the grinding degree appropriately, so as to ensure that the specific surface area of the clinker grinding is within a suitable range.
