Cement ball mill

Limestone is more commonly used in the cement preparation process, but the mined limestone generally has larger particle sizes and needs to be crushed. Generally speaking, processing limestone into cement requires the preparation and homogenization of raw materials, the preparation of pulverized coal, the calcination of clinker, and the grinding of cement. stage.

1. Preparation and homogenization of raw meal: natural limestone, clay, and exotic raw materials are crushed by a jaw crusher and mixed in a certain proportion, and then ground by a ball mill to prepare raw meal with appropriate composition and uniform quality;

2. Pulverized coal preparation: The coal required for calcining cement raw materials must be prepared into pulverized coal to provide the particle size required for pulverized coal combustion to facilitate full combustion and obtain sufficient combustion reaction capacity. In this process, pulverized coal can be directly added, and equipment such as jaw crushers and ball mills will be used for processing.

3. Clinker calcination: Put the lime raw material in the rotary kiln and calcine it until it is partially melted to obtain lime clinker.

4. Cement grinding: that is, adding an appropriate amount of gypsum, mixed materials or additives to the clinker to grind it into cement, and then package it for shipment.
