ZKZL series of clean powerful granulators are developed on the basis of absorbing and drawing on foreign advanced technology and combining with the current production status of petroleum fracturing proppants in China. They are mainly used in petroleum fracturing proppants (ceramic sand). ) Production, can also be applied to coal powder, limestone, coal gangue, clay and other powdery, granular, small pieces of material into balls.

The working principle of the ZKZL series of clean powerful granulators is to stir materials at high speed by using the reverse movement between the drum rotating at a low speed in the clockwise direction and the rotor rotating at a high speed in the counterclockwise direction, which are arranged at the bottom and wall of the drum, respectively. There is a scraper. The scraper cleans the layer on the inner wall of the drum and works with the tilted drum to change the specific flow field of the material. The powdery material is "kneaded" and nucleated during the high-speed movement. Granulate into balls.

The peculiar advantages of the ZKZL Granulator are:

1.The whole granulation process is carried out inside a fully enclosed drum, and the inside of the drum is in a slight negative pressure state, no dust pollution, clean and environmentally friendly;

2. The whole process of feeding-mixing-nucleation-granulation-shaping is controlled by computer using PLC, which is easy to operate and has a high degree of automation;

3. The rotor surface undergoes precise dynamic balance after abrasion-resistant treatment to ensure that it has good motion stability, reliability and abrasion resistance at high speeds, thereby making the machine work smoothly and reliably;

4. The surface of the scraper is wear-resistant, and the bottom and wall of the drum are equipped with wear-resistant liners, so the whole drum component has a high service life;

5. The drum unloading mechanism is fully hydraulic driven, which has the advantages of high degree of automation and reliable sealing with the drum;

6. The rotor and the drum are driven by the main motor and the auxiliary motor, both of which are AC variable frequency motors, which can adjust the speed in real time according to process requirements, with strong adaptability and wide versatility;

7. Through the mixing of high-speed rotor and low-speed drum, cutting and collision of materials with scraper to form specific material flow field, advanced granulation principle, high ball strength, good quality and high efficiency;

8. The structure of the whole machine is compact. The auxiliary hydraulic system and lubrication system are integrated into one, occupying a small space, and the overall appearance is smooth and beautiful.
