the Cement production line (Cement plant) is a cement equipment production line composed by a series of equipment. this production line mainly consists of the process of crushing and prehomogenization, raw materials homogenizing, preheating decomposition, cement clinker firing, cement grinding & packaging.

     the main equipments used in this whole production line include the vibrating feeder, jaw crusher, impact crusher, cement ball mill lifer, preheating system, cement rotary kiln and packing machine and so on. All the cement equipment in this line can be provided by our factory.

1.Crushing and Pre-homogenizing:

        (1) most of the raw materials, like limestone, clay, iron ores, and coal, should be crushed before their pre-homogenization. Limestone is the primary material in this line, and due to its large particle size and high hardness, its good crushing plays an important role in the whole line. Special stacking and reclaiming technology has been used in the pre-homogenizing process so that raw materials can be better primarily homogenized.

      (2)Raw material homogenizing: raw materials pre homogenizing is in the material piling up, by stacker to incoming raw materials continuously in a certain way piled material layer as much as possible parallel to each other, the upper and lower overlap and the same thickness. When, in the direction perpendicular to the material layer, as far as possible at the same time, cut off all material layer, in turn cut, until taken the end, namely "tile straight". The raw material yard has the functions of storage and homogenization

 

2.Raw material preparation:

          (1)Raw materials: raw ingredients with limestone, sandstone, iron ore, four flyash base ingredient database (or other special materials library), base bottom are respectively provided with a weighing feeder, quantitative various materials are given according to the requirements of the production process ratio. by the belt conveyor into vertical mill  system for grinding.

       (2)Raw material grinding: the material through the lock feeding device by a feeding chute to disc center, under the action of centrifugal force was thrown to the edge of the grinding disc delivered by grinding roller rolling mill, the crushed materials from the disc edge overflow, is from the nozzle speed upward with the hot air flow drying up, according to the airflow velocity different, part of the material was taken to the air high efficiency separator, coarse powder after separation, returned to the grinding table, re grinding; fine powder qualified with gas out flow after grinding and increasing dust mixed wet tower and electric dust collection, through the chute, the bucket is sent to the raw meal homogenizing silo within elevator and storage.

 

3.Raw meterial homogenizing:

        Raw meal in a downward landed, with air agitation, gravity, produce "funnel effect", try to cut the multilayer surface, fully mixed. the use of fluidized air different, make the base surface occurred in parallel streams of different sizes of expansion effect, some regional discharge, some regional flow, so that the base surface is generated within the tilt, radial mixing. In the production process of cement raw meal composition, stable pit entry is the stability of clinker burning premise of thermal system, raw meal homogenizing system plays a stable raw ingredients into the cellar of the final control action.
