● GZL Series Dry Mothod Roll Press Granulator

GZL系列干法辊压制粒机

Summary ：
Dry granulator is dry granulation equipment in our factory and absorption of foreign advanced powder granulation technology and development, and to improve and improve on the basis of foreign technique, more reasonable structure has the advantages of compact structure, simple process, convenient operation, good performance. The powder material by this equipment, uniform grain products without adding any binder can be made directly to the user needs, the particle density, the city no longer need to carry out the follow-up processing, reduce the process, not only reduces the cost of granulation, and reduce dust pollution, improve the working environment.

Application range ：
In addition to extrusion friction can cause dangerous explosion, the unit can be directly granulated for most dry powder materials. Through the rotary joint to water-cooling roller, this machine can also be granulation of heat sensitive materials.

Characteristic
▲ Dry granulation, without any binder, without drying two.
▲ The strength of particles can be adjusted. By adjusting the pressure of the roller, the strength of the particles is controlled.
▲ Products for the sand like irregular particles.
▲ Continuous production, high production capacity, high degree of automation, suitable for industrial production.
▲ Low granulation cost.

principle
1 、Horizontal granulator unit
The powdery material by vibrating hopper by quantitative feeder horizontal to the main feeder, stirring screw in the main feeder under the effect of degassing and was pushed to the pre arc groove around two set roll in. Two roll reverse in a pair of meshing gears under constant rotation. The powder through roll moment were rolled into sheet of dense material passed through the roll out of the elastic recovery under the action of roll down, a small sheet is not off by scraper. Two strip grooves of the surface of the roller to prevent the powder from slipping when being bitten by a roller. The blank into the crushing granulator granulation after entering the vibration sieve grading, with granular product requirements, under the sieve shaft vibration hopper circulation return powder granulation.

2 、Vertical granulating unit
The vertical granulating process besides different feeding mode and roll installation and horizontal granulating unit. Its working principle is identical. In the vertical granulation unit, the powder into the hopper agitator is stirred by vibration degassing, the spiral feeder is sent to the quantitative two roller set on the arc groove and is preloaded after granulation process and the same horizontal unit.
