Gypsum processing equipment and process
Gypsum introduction
Gypsum is a non-metallic ore with a composition of sulfate minerals. It is usually divided into two types: plaster and gypsum. After processing, gypsum can be widely used in construction, chemical, food, agriculture, medicine, metallurgy and other fields.
In order to improve the grade of gypsum and comprehensive recycling rate, the SBM expert team conducted in-depth research on the characteristics of gypsum, and tailored a reasonable set of gypsum processing equipment and process.
Gypsum processing equipment
1. Crushing equipment - jaw crusher
Since the gypsum after mining is relatively large, it needs to be crushed into a certain particle size by a jaw crusher before the next processing can be carried out. After the gypsum is crushed, gypsum particles with a particle size of less than 8 cm can be obtained, which can save a lot of time for the subsequent processing of the gypsum.
2. grinding equipment - ball mill
At present, the equipment suitable for gypsum grinding on the market is a ball mill. The equipment has the following good effects: (1) The gypsum of the grind is finer and more uniform, the product fineness can be formed at one time, the quality is better, the energy consumption and electricity are The consumption is relatively low. (2) The processing capacity of gypsum is large, the output is higher, the grinding efficiency is 3-5 times that of the same type of equipment on the market, and the running cost is extremely low. (3) The design of the automatic control system effectively improves the automation of the equipment, and the operation control is more simple and convenient.
3. calcining equipment - rotary kiln
Rotary kiln is a gypsum calcining equipment with high sales volume on the market. Its main structure includes kiln head, kiln tail seal device, rotary cylinder body, support device, roller device, etc. The kiln body is made of super wear-resistant material. Casted with good high temperature resistance, impact resistance and toughness, and low failure rate.
4. cooling equipment - cooling machine
After the gypsum is calcined, it needs to be cooled by a cooling machine.
5. drying equipment - dryer
Since the processed gypsum contains a large amount of water, it seriously restricts the application of gypsum in various industrial fields, and it needs to be dried by a dryer.
Gypsum processing process
First, the mined gypsum is uniformly fed into the jaw crusher through a vibrating feeder to be crushed to obtain gypsum particles having a particle size of less than 8 cm. After screening by a siever, the large-grained gypsum is re-crushed, in accordance with The required gypsum is sent to the ball mill for grinding by the bucket elevator. After grinding to a qualified particle size, it enters the rotary kiln for calcination. The calcined gypsum is cooled by a cooler because it has a relatively high temperature. The gypsum is sent to the dryer for drying by the belt conveyor, and the dried gypsum material is sent to the finished silo for storage.
The above is the introduction of gypsum processing equipment and process flow. SBM has excellent technology and rich production experience. It can provide users with reasonable material processing equipment and process flow according to the user's production requirements. Welcome to the intended users. Come to investigate.
