GZL Series Dry Roller Pressing Granulating machine
Adopts dry pressing technology to pressure material with moisture content of lower than 10% into sheets, and its processed into required particles through breaking, granules treaming and screening process.
Features
The material is pressed by exterior force, and passes through the gap between the two rollers which are rotating in different directions, and then it's pressed into sheets. The mass density of material might increase 1.5-3 times, so to achieve required strength.
The material is forced and to be pressed by mechanical force, without any additional ingredients, so to ensure purity.
The dry material is made into granules directly, no need 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 compare to other method of granulation. It's especially applicable for to increase the mass density of product.
The pollution of environment is controlled, the wasted powder is reduced, the packaging fee is decreased and the product is easier in transportation.
Freely according to the property of material.
The material feeding adopts non-step inverter control, the automation level is high. One operation high control muti-units of machine. The labor intensity is low, and the machine might run continuously in long time.
Principle
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.
Dry material powder is fed from the top of the equipment, de-air, 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 noodles 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.
Flow chart
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 pre-pressed 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 of oil 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.

Changzhou Yibu Drying Equipment Co., Ltd is a leading manufacture of drying, mixing, granulating equipemnt in the main land of China, a specially- designated enterprise of China Association of Pharmaceutical Equipment and China General Chemical Equipment Corporation, covers more than 50, 000sq. M, holds RMB 38 million of fixed assets and has more 180 sets of special processing equipment and powerful technical force, own the provincial famous trademark "YIBU". It can produce more 1, 500 stes of different. At present, there are 28 kinds and over 160 of specifications and varieties. The credit level is AAA for the passing days. ISO9001 & ISO1400 are approved.
The founder, Mr Zha Guocai devotes research, manufacture, production and business of drying equipment for over thirty years, holds the post of Deputy Director-General of China Drying Equipment Association for a long time.
The company pays much attention to science and technology renovation. First or later, it has cooperated with the institutes that are Shanghai, Wuhan, Chongqing and so on, and cooperated with Shenyang Chenmical Institute, Ministry of Chemical Industry, Qinghua University, Shanghai transportation University, Dalian Science and Technology University. Therefore the company can put 3-5 new varieties into the market every year. In 1998, through approval of state relevant departments, the company set up China Research Center of Drying and Granulating, that can research new process and develop new technology and provide new products for pharmaceutical, chemical and foodstuff industries. We have many testing machine in our lab for to make trials for clients.
We've sold equipment to USA, Mexico, Columbia, Guatemala, Brazil, Peru, Australia, New Zealand, Ghana, Russia, Cyprus, Greece, Iran, Indonesia, Philippines, Korea, Japan, Taiwan, Hongkong and so on totally nearly 50 countries and districts around the planet.
