FEATURES

The cement production line flow includes crushing and prehomogenization, raw material preparation, raw material homogenization, preheat decomposition, cement clinker calcination, cement powder grinding, cement packing. Among the seven main steps, cement mill, cement rotary kiln and other cement equipment play the key role in cement making process.

In a cement plant, ingredients for cement production go through the following several processes.

Cement Production Line Flow

1. Crushing and Preblending

In cement plant, most of the materials need to be crushed such as the limestone, coal and other minerals. After the mining, the size of limestone with high hardness is large, so the limestone crushing plays a more important role in cement plant.

2. Raw Material Preparation

In cement plant, producing each 1 ton of Portland cement needs at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum). Grinding operation consumes power about 60% of total power in cement plants, raw material grinding takes more than 30%, while coal mill used in cement palnt consumes 3%, cement grinding is about 40%. So choosing the right grinding mills in cement plant is very important.

3. Raw Materials Homogenization

Adopting the technology of homogenization could rationally get the best homo-effect and afford an eligible production to the demand.

4. Preheating and Precalcing

Preheater and calciner are the key equipment for precalcing production technique.

5. Burning Cement Clinker in Rotary Kiln

The calcination of rotary kiln is a key step of cement production , it leaves direct influence on the quality of cement clinker.

6. Cement Grinding

Cement grinding is used for grinding cement clinker to the appropriate size, optimizing cement grain grading, increasing the hydration area and accelerating the hydration rate to meet the requirements ofsetting and hardening of the cement paste .

Due to the simple operation, safe use and stable performance, Hongxing clinker cement production machinery is traditionally used for producing different types of portland cement, portland-pozzolana cement, slag portland cement, portland fly-ash cement and composite portland cement.
