China famous cement equipment supplier ZOONYEE

 Introduction:

The cement manufacturing equipment of cement kiln system, rotary kiln system,  cement grinding station and grinding system play main roles in clinker cement production line.

 Advantage:

1. This clinker cement production line adopts advanced technology and equipment of current cement industry. With the advanced technology and dependable equipment, great economy benefits can be acquired.

2. The high-efficiency low-resistance five-stage cyclone pre-heater and cdc furnace system with high gas adaptability, high classification efficiency, high heat exchanging efficiency and low system resistance will be adopted at the kiln inlet, so as to increase the output of clinker. china complete cement machine,cement mill,cement production line 

3.  New technology will be adopted at the rotary kiln head.

4.  In the raw meal grinding section, air swept drying mill is adopted. The raw material is dried by waste heat from the kiln inlet to save energy and investment.

5.According to technology requirements of the new dry process rotary kiln, advanced computerized dcs control system is adopted for the control of main production parts from bottom of raw material blending silos to top of cement silos. And PLC control system is adopted for other parts.

6.Great importance has been attached to the environment protection in the plan. In order to measure up to the environment protection standard, advanced and practicable dust collectors are adopted at all dust generating points.

Brief introduction of process:
1) limestone crushing
2) raw material storage and blending
3) raw meal grinding
4) raw meal homogenizing and kiln feeding
5) kiln inlet, kiln middle, kiln head and pulverized coal preparation
6) waste gas treatment at kiln inlet
7) clinker and admixture storage
8) cement grinding
9) cement storage and packing

1. Crushing

In this process, most of raw material should be crushed, such as limestone, clay, iron ore and coal. Limestone is the largest amount of raw materials in cement production line, so it is very important in cement production line.

2. Pro-homogenization

Raw material pro-homogenization is making the raw material yard with storage and pro-homogenization function by applying scientific stacker technology.

3. Raw material preparation

In cement production process, to produce 1 ton of Portland cement must grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum). According to statistics, grinding operations in the dry-process cement production line need to consume power accounts for about 60% of the whole plant power, of which 30% of raw material grinding, more than about 3% of coal mill, cement grinding about 40%. Therefore, a reasonable choice grinding equipment and processes, optimizing the process parameters, proper operation and controlling operation system is of great significance.

4. Raw material pro-homogenization

The system of raw material pro-homogenization plays a raw meal of raw ingredients stability of pit entry last gatekeepers.

5. Preheat & decomposition

Raw material preheating and decomposition is completed by preheater, which can improve the kiln system productivity and reduce heat consumption of clinker Purposes.

6. The burning of cement clinker

Raw material is carried out into the rotary kiln clinker for completion after preheating in the preheater and pre-decomposition

7. Cement grinding

Cement grinding is the last process of cement production line, also the most power consuming process. Its main function is to grind the cement clinker (and gelling agent, performance tuning materials, etc.) into the appropriate size and a certain particle size distribution, which is for increasing the size of its hydration, accelerating the hydration rate and meeting the coagulation, hardening requirements.
