The trapezoidal mill is used for grinding and screening gypsum, with a capacity of 3-36T / H and a feed particle size of 0-40mm. Gypsum is a kind of widely used industrial material and building material. Industrial gypsum is more common, and it is also the main raw material for the production of gypsum cementitious materials and gypsum building products, It is also the retarder of Portland cement.
After the gypsum is calcined at 600-800 ° C, a small amount of lime and other catalysts are added to grind it together to obtain anhydrite cement (also known as Kim's cement); After calcination at 900-1000 ° C and grinding, high-temperature calcined gypsum can be obtained. The production capacity of 30T / H can be ground by trapezoidal grinder. The advantages of trapezoidal grinder for gypsum are as follows:
1. The overpressure trapezoidal grinding machine has an automatic control system, which can realize remote control, easy operation, less human resources, and help enterprises save labor costs.
2. Soft connection is adopted between the main machine and the powder separator. The shock-absorbing spring and the sealing belt reduce vibration and noise and avoid resonance.
3. The grinding roller assembly is connected together through a pull rod and a horizontally placed spring, and the radial force generated by it avoids the loss of the main shaft and bearing after large materials enter the grinding chamber, and improves the service life of the equipment.
4. The system works under negative pressure, without dust spillover, and the environment is clean. Moreover, the equipment has small vibration and low noise during operation, which meets the environmental protection requirements. Generally, the trapezoidal grinder will be equipped with corresponding dust removal equipment, and the equipment is sealed as a whole.
5. Due to the short residence time of materials in the mill, it is easy to detect and control the particle size and chemical composition of products, reduce repeated grinding and stabilize the product quality.
SMMVIK Machinery overpressure trapezoidal grinder can process various non flammable and explosive materials with humidity below 6%, such as quartz, feldspar, gypsum, calcite, etc. We customize products according to the needs of users, and the quality and capacity of the trapezoidal mill are in the forefront of the industry.
