Double Roller Press Granulator

Features

1.The machine adopts no drying process production, normal temperature granulation, one-time forming in mold. With less investment, quick effect, good economic and other advantages.

2.The structure of the machine adopts granulation, molding and screening as one, which makes it has the characteristics of beautiful appearance, simple operation and low energy consumption. The main parts such as roller is made by a new type of refined metal, with the features of corrosion protection, abrasion resistance, shock resistance.

Among which, the DZJ-Ⅱmachine is not only with the above characteristics, but also the rack part has been upgraded. For the bearing frame, we choose high quality anti-corrosion casting as a whole component. With more stable performance, it can greatly improve the service life of the rolling bearing and shaft.

For the transmission part, we apply the dual input transfer mode, which not only improve the input power ratio, but also ensure the transmission gear lubrication and sealing performance. This machine has the advantages of compact structure, good stability, good sealing, low noise, easy operation and maintenance, etc. The new machine has won the majority of users praise as soon as it is listed.

3.Wide adaptability of raw materials, our machine can not only be used for fertilizer, feed, chemical industry granulation, but also have good applicability especially for rare earth, metallurgy, coal, biological agents, environmental protection projects.

Working principle

Driven by the motor pulley, the belt passed through the reducer to a pair of sliding mold shell with two high pressure roller bodies, make them to do the opposite work. For the DZJ-Ⅰtype extruder, between the two rollers is a group of counter gears interaction with each other. While the DZJ-Ⅱ-type extruder, the two rollers are directly driven by a dedicated reducer on the two output shaft, and finally reach the purpose of granulation.

During the production process, the raw material is fed into the hopper, then counter extrusion forming through the high pressure roller bodies. After demoulding, the material flow to the broken forming bin under the rollers. The driving force of the crushing and forming comes from the relative movement of the sprocket of the driving roller shaft, which is transmitted through the chain to the pair of crushing rollers. After the crushing broken forming bin, the finished product particles are sifted out through the screen and discharging trough.
