Zhengzhou Jinma Mining Machinery Co., Ltd. offers the complete main equipments of the Mini Cement Plant, capacity from 50 tons per day to 1500 tons per day.

Generally, the Mini Cement plant consists of raw material grinding, blending, pre-calcining, clinker burning and cement grinding.

The equipments in this whole production line are vibrating feeder, jaw crusher, impact crusher, cement ball mill, lifer, preheating system, cement rotary kiln, rotary dryer  and packing machine and so on. All the necessary equipments in this line can be provided by Jinma Factory. Our factory has exported several complete mini cement plants in the past 2 years.

Mini Cement plant process

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 stage of cement plant 

Cement grinding is the last process of cement plant, 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.

Simplified process of Mini cement plant:

Raw materials extraction (mining) → crushing→ raw materials storage and pre-homogenization (ball mill) →raw material homogenization and storage, calcinations (raw material enter into rotary kiln after pre-heater in cyclone tube, calcinated to clinker) → cement grinding (mix other chemical material according to cement quality to grind) → cement storage and transportation
