Detailed Presentation on HXJQ Dry Cement Production Line

Hongxing cement production line has many advantages, such as large capacity, high degree of automation, high quality, low energy consumption, low emissions of harmful substances, big industrial waste utilization volume.

Process flow of new dry process cement production line

1. Crushing and pre-homogenization.

In the process of crushing cement production, the majority of raw materials must be crushed, such as limestone, clay, iron ore and coal. Limestone is the largest amount of raw materials for cement production, the larger particle size after mining, high hardness, thus limestone crushing at the cement mechanical material crushing plays a more important role. Raw pre-homogenization technology is that during the save, take the process of the material, use the scientific stacker reclaimed technology to realize the initial homogenization of raw materials, make the raw material yard also have the function of storage and homogenization.

2. Raw material preparation.

In the process of cement production, produce one ton of portland cement equipment need grinding at least three tons of material (including raw materials, fuel, clinker, mixture, plaster), According to statistics, dry-process cement production line grinding operation consumes power accounted for about 60% of plant power, which raw material grinding accounts for over 30%, coal grinding accounted for about 3%, cement grinding accounted for about 40%.

3. Raw material homogenization.

In the process of new dry cement production, the stability of pit entry clinker raw material composition is the premise of stabling firing thermal system, which plays the last gatekeeper role about stable raw material composition pit entry.

4. Preheat decomposition.

Raw material preheating and partial decomposition accomplished by the preheater, instead of part of rotary kiln, make the kiln conduct gas heat transfer process with stacked state, move to pre- internal heat under the suspension, make the raw material to the same hot kiln exhaust gas mixing, increasing the contact area of the gas feed, fast heat transfer, high heat exchange efficiency, to improve production efficiency of kiln system, reducing the clinker burning heat consumption.

5. Cement clinker burning.

After the raw material in the cyclone preheater finish preheating and pre-decomposition, the next step is to enter a rotary kiln for clinker burning.

6. Cement grinding.

Its main function is to make cement clinker (and gelling agent, the performance moderator material) grinding to a suitable size (in fineness, specific surface area, said), form a certain particle size distribution, increasing its hydration area, accelerate hydration rate, to meet the cement paste coagulation, hardening requirements.

7. Cement packaging.

There is having two packing methods: bagged and bulk.
