GK Series Indoor chemical fertilizer dry granulation roll compactor,Absorbed foreign advanced technique of powder granulator, improved and heightened on the basis of foreign technique, this dry-type granulator is developed by our factory. It has more reasonable and compact structure, simply technological processes, easy operation and better performance. Powder materials can be made into even granules customer needs without adding any bonding agent when they run through the machine. As density of granules are larger, no any afterward process is needed so as to reduce technological process, reduce granulation cost and powder pollution and improve labor environment as well.

Features

1. Making granules from dry powder directly without any bonding agent.

2. The strength of granule can be adjusted by pressure of rollers so as to control strength of granule.

3. Sand-shaped irregular granules are produced.

4. Large productive capability due to continuous production. High degree of automation to suit automatic production.

Working Principle

Vertical Feed Set After weight measured powder materials are sent laterally by the vibration hopper to the main feeder, deaerated by the stirring screw of the main feeder, pre-pressed and pushed into the arc grooves of left and right rollers. Driven by a pair of meshed gears, two rollers rotate in opposite direction with same speed, and powder materials are pressed into dense sheet while they run through rollers. Under the function of elastic recovery after rollers, they'll be separated from rollers and drop down, and fewer sheet not dropped will be scrapped off by the blade. Stripe grooves evenly distributed on the surface of rollers can prevent sliding when powder materials are fed into rollers. After crushed and granulated, they'll pass through the vibration sieve to be graded, and granules which meet requirement can be obtained. Powder after the sieve will return to the vibration hopper to be granulated circularly.
