Dry roller pressing granulator
Product Description
Principle of work
Dry material powder is fed from the top of the equipment, desaeration, screw-pre-press, enter into the gap between the two rollers that are rotating in opposite directions. The pressed material falls down because of surface tension and gravity when passes through pressing section. The noddies shaped material then enters into breaking machine, been smashed by rotating knife. The smashed material enters into granulator, and then the particles and part of powder material enters into sieve by the rolling knife, and then the product is separated. The product up to standard will be conveyed to product silo by conveyor; the material under the sieve should be fed back and should be pressed again. The pressure might adjust by the hydraulic oil cylinder according the requirements of granulation.
Sheet, bar and other shape of product might be procured by choose the relative shape of the grooves on the surface of the roller.
Applications
Petro-chemical, fine chemical, pharmaceutical, foodstuff, metal powder, Bio-engineering, pesticide, fertilizer, mine and coal.
Technological process
The material enters into the hopper lifting machine through spiral conveyor from the feeding port, and then it's delivered to vibration material silo. A metered feeder will feed the material into inverter controlled spiral feeder, and the material is then pre-pressed The prepressed material enters into the gap between the two rollers that are rotating in opposite directions, and then it's firmly pressed. The firmly pressing force is transferred to the material through the pushing force ofoil cylinder. The firmly pressed material sheet falls into the breaking machine automatically, and been smashed into granules of different sizes, and then enters the granulator to be trimmed. The trimmed granules is squeezed out into the sieve through a mesh board. The final product enters into hopper lifting machine, and then it's conveyed to final product silo.The material sieved out should be fed back to the material silo by spiral conveyor, so to perform the next circulation.
