At present, traditional disc granulator is mainly used in the domestic ceramic sand production. The price of this kind of equipment is low, but its capacity is small, pelletization rate is low and added ingredient is required. Especially, it leads to severe dust pollution, occupies a large plant area and labor intensity is large. Under the trend of increasingly high requirements and strict management of environment and labor protection in our country, it has become an inevitable choice for the healthy development of industry to eliminate this kind of granulating equipment out of time.

In view of this, CARBO Corporate has pioneered in introducing German Eirich RV15 granulators, achieving good economic and social benefits,drawing great attention from the domestic ceramic sand industry. However, Eirich granulator is very expensive, which limits its widespread use in our country.

Aiming at the urgent demands of technological upgrading in domestic ceramic sand industry, Henan Zhengzhou Mining Machinery Co.,Ltd.has successfully developed a similar kind of advanced granulator by the way of collaborative research and innovation. It is capable of fully meeting the requirements for clean and efficient production of a variety of ceramic sands.　

ZK-15 New Type Granulator is mainly composed by the rotor, rotor component, scraper, discharger, supports and other components. The main structural features are:

1.The rotor and the drum speed are controlled by continuously variable frequency. It's convenient to adjust the rotor and drum speed according to process requirements. It's also more energy-efficient and lower energy consumption;

2.The particular eccentric position of internal drum has a rotor. The rotor is connected with the main motor through a belt. There's a planetary rotor disk at the bottom of the rotor. The Rotor disk and drum take reverse high-speed rotation. It is convenient for formation of specific flow field to achieve fast, powerful granulation;

3.The inside and the bottom of the drum are arranged a wall scraper and bottom scraper which can be adjusted at upper and lower, left and right direction. It can easily adjust the gaps between wall scraper, bottom scraper and the drum to make up the scraper wear.

4.All the wearing parts of planetary rotor disk and scraper are taken special surface treatment to have high hardness and wear resistance;

5.The connection parts between drum and supports have multiple sealing materials to ensure internal drum without dust leakage to achieve clean, environmentally friendly production;

6.There's a hydraulic driven discharger at the bottom of the drum. It ensures good sealing while achieving discharging automated control.
