Calcium Aluminate Rotary Kiln

Calcium aluminate rotary kiln

Our company is often committed to the research of calcium aluminate rotary kiln, the various common symptoms of the rotary kiln were studied, and effectively solved the calcium aluminate rotary kiln ring formation, low output, large energy consumption and other conditions. Compared with the traditional process with the same specification kiln type, the output is increased, the heat consumption is reduced, the flue gas temperature is < 250℃, it is easy to collect dust, and it meets the requirements of modern energy saving and environmental protection.

Capacity: 30-800t/d

Specification: Φ2.2×38-Φ4.3×64m

Application: Calcium aluminate rotary kiln has been widely used in chemical industry, environmental protection, sewage treatment, iron and steel industry, calcium carbide industry, pulverized coal mixed combustion and so on. Calcium aluminate rotary kiln is used in addition to calcination of this mineral.

Calcium aluminate rotary kiln product introduction

The raw material of calcium aluminate rotary kiln is composed of limestone and bauxite, formed by high temperature calcination to Ca, Ca2 as the main component of the sintered material, the production of finished products can be used as polymeric water filtration agent, efficient concrete expansion agent, refractory castable raw materials, the production of finished products is good, economic benefits are significant.

Outstanding advantage

1. Calcium aluminate rotary kiln has the characteristics of simple structure, reliable operation and easy control of the production process. Can be widely used in chemical industry, environmental protection, sewage treatment and other industries.

2. The new technology calcium aluminate rotary kiln has overcome the combustion problem of high calorific value of coke oven gas and short flame, and can make full use of the remaining coke oven gas.

3, calcium aluminate rotary kiln for small and medium-sized iron and steel enterprises, coking enterprises, calcium carbide enterprises, and refractory industry has a very good energy saving, environmental protection, efficiency effect.

Working principle

The raw material is fed directly into the end of the calcium aluminate rotary kiln through the electronic belt measuring scale, belt conveyor, ballast bin and air lock valve from the storage, and only the ballast bin is set at the end of the kiln to reduce investment. The raw material enters the calcium aluminate rotary kiln and is heated first, and moves in the kiln and the hot gas flow in reverse direction. After the raw material is heated to the reduction temperature in the heating zone, it enters the reduction zone. The central temperature of the flame in the reduction zone is controlled at about 1000℃, and the temperature of the hot atmosphere in the reduction zone is controlled at about 700℃. After entering the cooling belt, the gas meets the incoming gas, the gas is preheated, the finished material is cooled out of the kiln, and the water is cooled by the continuous bucket conveyor, and the storage is ready for selection.
