Granulator description

Adopt dry pressing technology to press materials with moisture content lower than 10% into sheets, and then materials are processed into required particles through breaking, granules treaming and screening process.
The material is pressed by exterior force, and passes through the gap between the two rollers which are rotating in opposite directions, and then it's processed into sheets. The mass density of material might increase by 1.5-3 times, required intensity can  be achieved

Features

The material is cnstrainedly pressed by mechanical force, without any additional ingredients, thus purity is ensured
The dry material is made into granules directly, no need for any further drying process. So it's good for product process.
The strength of the particles are high, the mass density is increased more apparently compared to other methods of granulation. It's especially applicable for to increase the mass density of product.
The pollution of enviroment is controlled, the wasted powder is reduced, the packaging fee is decreased and the product is easier in transportation.
The structure is compact, the maintenance is convenient, the operation is simple, the process is short, the energy consumption is Iow, the efficiency is high, the probablity of fault is Iow, the application range is wide, and the pressure of roller might be adjusted freely according to the property of material.
The materiar feeding adopts non-step inverter control, the automation level is high. One operation migh control multi-units of machine. The labor intensity is Iow, and the the machine might run continuously in tong time.
Adopt high quality alloy, stainless steel, Ti, Cr and other metal for driving parts, the wear-resistance, cossive-resistance, thermo-resistance and pressure-resistance is highly increased. The service life is long.

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.
