Brief description of the structural composition of Dry powder pressing mold

Apr 26, 2018

Dry powder pressing mold is a type of powder, iron powder, coking coal, aluminum powder, iron filings, iron oxide skin, carbon powder, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke, etc. Various powder, powder, waste, waste equipment. In addition, the Dry powder pressing mold can also be widely used in refractories, power plants, metallurgy, chemical industry, energy, transportation, heating and other industries. After the molding equipment, the material is energy-saving, environmental friendly, easy to transport, and improves the utilization of waste materials. Rate, with good economic and social benefits.

Dry powder pressing mold structure composition:


The Dry powder pressing mold uses a 65-manganese cast. After a special heat treatment, the hardness can reach 58 degrees or more. The roll skin is assembled and replaced after wear. Dry powder pressing mold has a buffer device to better protect the equipment from hard objects. This device will also be designed with adjustable devices so that the two-roller ball bowl is always within the adjustable range.


Dry powder pressing mold structure principle:


The Dry powder pressing mold will also be mainly driven by the main motor, through the v-belt, to the reducer, the reducer through the coupling, to the drive shaft and then to the open gear, to ensure the synchronization of the two rollers (constant speed To the piston of the passive roller hydraulic cylinder (constant pressure type is supported by oblique iron).


The system pressure is ensured by the hydraulic circuit, the liquid control valve and the accumulator, and the material is uniformly entered into the hopper of the forming machine by the quantitative device through the storage silo, adjusted by the regulating gate on the hopper, so that the material enters the middle of the roller uniformly, and the speed is constant. The unit forming pressure of the oppositely-operated pair of rollers for compressing the material increases from small to large, and the forming pressure reaches the maximum at the center line of the pair of rollers. After the material passes the line, the forming pressure rapidly decreases to make the material enter the state and the processing is smoothly realized.


Dry powder pressing mold manufacturing process


When the Dry powder pressing mold is processed, it must also be noted that it is customized according to the requirements of the customer, and the workpiece has a bulk density of 1.9-2.2 g/cm3, and the drop strength is equivalent to that of the block lime. After processing, after screening, qualified parts enter the finished product warehouse for smelting and use.
