Cement plant is very popular at abroad, while rotary kiln belongs to building material equipment, is the main equipment for sintering cement clinker in cement production plant, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.
Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry; For calcimine of calotte and aluminum hydroxide in aluminum manufacturer; For claiming of chrome sand ore and chrome powder ore in chemical plant.
In cement plant, rotary kiln, ball mill is the indispensable equipment. Rotary kiln production and ball mill producted by Henan Zhengzhou Mining Machinery Co., Ltd. Can improve the efficiency of the cement production, saving energy, let you get more economic interests. Welcome general customers order. Production capacity:
Cement production technology and equipment is the advantage of my plants, my plant the production of cement rotary kiln, cement mill can be used in the 100 tons to 6000 tons of cement plant.
Complte steps of cement process:
Step1: Raw materials Preparation--Limestone crushing
A. Process introduction: Limestone is the main raw material in cement production, and most factories are located near the limestone by blasting or use the loader to the mining of raw materials limestone, transported to the crusher into fragments. B. The main raw material: Limestone, clay, iron ore
Step 2: Raw material grinding --Limestone, clay, iron and other raw materials
Process introduction: The use of ball mill or vertical mill raw material is ground to a powder, and then by conveyor transport to preblending yard for storage and further material mixed.
Step 3: Calcining clinker--raw material powder after homogenization
A. Process introduction: The homogenized material enters the preheating decomposition system, decomposition rate of 95%, into the rotary kiln, clinker.
B. List of equipment and processes: Preheater, Decomposition furnace, Rotary kiln, Ball mill, Cooler, Clinker conveyor belt, Belt conveyor, Dust collecting equipment etc.
Step 4: Cement grinding--Clinker, gypsum, mix materials and so on
A. Process introduction: Clinker, gypsum, mixed materials in a ball mill, cement grinding into a qualified drug cement. The use of the powder selecting machine can conveniently adjust cement drug, to achieve energy saving production
B. Main Products: Ball mill, Powder selecting machine, Bucket elevator, Air chute, FU chain conveyor, Dust collector etc.
Step5: Cement storage, packaging--Finished cement belt/bulk delivery
A. Process introduction: The use of packaging machines and automatic loading machine can achieve the shipment of bagged cement factory, use bulk cement equipment can realize bulk cement canning factory
B. Equipment: Conveying equipment, Dust collecting equipment, Belt conveyor, Elevator Air chute, Spiral screw conveyor etc.
