The ZK suspension calcination system is suitable for the calcination of various powdered materials, such as limestone, dolomite, coal gangue, magnesium carbonate, aluminum hydroxide, etc. For different materials, the requirements for raw materials and product quality are different.

(1)The fine particle high-quality resources that cannot be utilized by rotary kilns and shaft kilns have been fully utilized

(2) It has low heat consumption and saves more than 30% energy compared with the traditional rotary kiln production process

(3) cover a small area

(4) It has a large production capacity, a high level of automation, flexible production adjustment, high product activity and uniform quality

(5)It is suitable for large enterprises to produce high-quality products

The powdered materials stored in the raw material silo (such as limestone, dolomite, coal gangue, magnesium carbonate, aluminium hydroxide, etc.) are conveyed and measured by the screw conveyor at the bottom of the silo and the screw metering scale, and then fed into the secondary cyclone preheater (commonly known as the Venturi dryer) by the feeding screw conveyor for initial preheating. The initially preheated materials are carried into the first-stage cyclone separator of the suspension furnace along with the hot gas flowing through the air duct. The mixed gas undergoes gas-solid separation in the first-stage cyclone preheater. The separated solid materials are then blown away by the hot gas (with a gas temperature of approximately 500 to 950℃) coming out of the third-stage cyclone preheater of the suspension furnace and come into full contact with the hot air for further preheating. Then it enters the second-stage cyclone preheater of the suspension furnace with the hot gas flow for gas-solid separation. The hot air coming out of the first-stage cyclone preheater of the suspension furnace enters the subsequent flue gas treatment system for desulfurization, dust removal and denitrification treatment before being discharged. The materials are discharged from the three-stage cyclone preheater and sent to the five-stage suspension furnace for calcination. After five stages of preheating, calcination and three stages of cooling, the products are sent to the finished product storage by the bucket elevator.
