High Efficiency Zinc Oxide Rotary Kiln/ Calcite Rotary Kiln

Zinc Oxide Rotary Kiln Application:

Rotary Kiln belongs to building material equipment, according to different materials, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln. Cement kiln is used for making cement clinker and there are dry and wet methods to make cement clinker. Metallurgy chemical kiln is widely used for magnetic roasting of poor iron ore and oxidizing roasting of chrome and nickel in the steel factory; backing high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminum factory and baking chrome ore and chrome powder in the chemical plant. The Lime Kiln is used for roasting active lime in steel works and ferroalloy plants and light roasting dolomite.

Zinc Oxide Rotary Kiln Structure:

1. The upper feeding system: includes the upper hopper, the next material possession, the next feeding method and structure can guarantee to the pre-heater of the body feeding to achieve security when closed. So that the cold air from outside can not enter into the preheater and feeding can make use of valve rod to achieve continuous or intermittent feeding.

2. Preheater body: it is to ensure that material preheated to 900 degrees celsius of the most important part. It is by the warm room, hanging devices and brick lining (which does not belong to the scope of design and manufacturing equipment) and other parts. That part of the structure of most of metal structures, part of the material according to the need to use a heat-resistant steel, heat-resistant steel to 1100 degrees celsius in 1000 to work under high temperatures. In addition, the refractory bricks lining structure, novel design, sealing is good, can guarantee the material in pre-heater evenly and achieve pre-heating temperature preheating.

3. Pusher devices: mainly rod, framework, and connecting rods and other parts of rod using heat-resistant steel casting or welded together, can withstand high temperatures, using electronic control and hydraulic systems can be by putting the various hydraulic automatic control program to achieve sequential pusher.

Working Principle Zinc Oxide Rotary Kiln:

Material is fed into kiln though end of kiln (higher side of cylinder). Because cylinder is inclined and it rotates slowly, material moves along with circle as well as axial direction (from higher side to lower side). After going through physical and chemical change, material gets into cooling machine through head cover of kiln after the finishing calcination. Fuel is fed into the kiln head through the kiln head, and exhaust gas will discharge at the end of kiln after exchanging heat with material.
