cement grinding table segments

cement grinding table segments is mean a whole set of cement production line composition by a series of cement equipment. Mainly by crushing, raw material preparation, homogenization, preheating decomposition, calcination, and cement grinding. Machines used in cement industry is mainly about jaw crusher, rotary kiln, cement ball mill, etc.

Cement Crushing Plant

Cement crush is the first step in cement production line. Most of the raw material need to broken, such as limestone, clay, iron ore and coal etc. So cement crushing plant play an important role in cement production line. The limestone is the most used raw material, the mining of limestone with big particle size, hardness higher, so jaw crusher is mainly used in this step.

Raw Material Preparation

In cement production process, one tons of silicate cement equipment at least need three tons of grinding materials (including all kinds of raw materials, fuel, clinker, mixture, gypsum), so we should reasonable configuration in order to ensure the quality of the cement.

Cement Calcination

In this process, the main equipment is rotary kiln. We offer rotary kiln with large capacity and long working life.

Cement Grinding

Cement grinding is the last step of cement production line. After this process, we will get powder cement. Cement ball mill is most widely used in this process.

Cement Manufacturing Process

The cement manufacturing process involves four distinct stages, and these are outlined below:

1. Quarrying
The raw material for cement manufacture is a rock mixture which is about 80% limestone and 20% clay or shale. These are quarried and stored separately. The lime and silica provide the main strength of the cement, while the iron reduces the reaction temperature and gives the cement its characteristic grey colour.

2. Raw material preparation
The steps involved here depend on the process used. There are two main cement manufacturing processes currently used in the world: the dry process and the wet process. The dry process uses more energy in grinding but less in the kiln, and the wet process has lower overheads than the dry process.

3. Clinkering
This is the step which is characteristic of Portland cement. The finely ground material is dried, heated (to enable the sintering reactions to take place) and then cooled down again. While it is being heated various chemical reactions take place to form the major mineral constituents of cement.

4. Cement milling
To produce the final product the clinker is mixed with gypsum, which is added as a set retarder, and ground for approximately 30 minutes in large tube mills. The cement flows from the inlet to the outlet of the mill, being first ground with 60 mm then 30 mm diameter steel balls. The first grinding breaks up the material and the second grinds it to a fine powder. The amount of grinding is governed by the volume of cement fed into the mill: the greater the volume the coarser the grind. This has practical limits, with too much cement clogging up the mill and not enough actually increasing the particle size.

The particle size is measured by laser diffraction analysis, and the quantity of material entering the mill adjusted accordingly. Over time the charge wear out, so when they reach a certain size they fall through a seive and then are replaced.
