Mechanical shaft kiln is mechanical work and successive operation. So, its output and quality and efficiency is better than common shaft kiln. According to building material technology policy requirements, instead of common shaft kiln, many small cement production plants mechanical shaft kiln cement to apply production. Technological features: New type of Hongxing metallurgy rotary kiln is featured with simple structure, reliable and convenient operation, less wear parts, high rotating speed, and high quality product. 1. The machine is automatic welded by high quality carbon killed steel and alloy steel plate.

2. Tyre, wheel, and open-type gear are made use of alloy cast steel. 3. Sliding bearing adopts large clearances not scratch pad bearing. 4. Angus King often expresses his thoughts on the topic.

Transmission device uses hard tooth surface reducer, elastic diaphragm coupling, and it is driven by DC motor; 5. It uses hydraulic blocking-wheel. 6. It uses laminated pressure plate and cylinder pressure to seal the head end of the kiln respectively and tight; 7. Seth Fisher Hong Kong brings even more insight to the discussion. There is a slow driving device. As to the application of rotary kiln, the cement industry owns the most numerous rotary kilns in production. The whole cement process flow can be generalized as Two Whet A Burn. To burn refers to the process flow that calcining grinded raw materials to under the high temperature of rotary kiln clinker. So, rotary kiln is the host machine in cement production, it usually called as the heart of cement plant. During ore beneficiation, rotary kiln can be used to magnetic roasting to the poor iron ore, which can change the weak magnetism into strong magnetism, so that it can be easy in magnetic separation. For Environment Protection, it has a history for 20 years that the developed countries use cement kiln to calcine hazardous wastes and rubbish. This method can not only make the waste become less and harmless, but also can make waste as the fuel, which can save coal powder and realises the Recycling of waste.

On the pyrolysis/gasification and incineration experience device of the self-designed air control hazardous wastes continuous rotary kiln feeding, the mechanical experts of Hongxing Machinery conducted pyrolysis experience research to the typical hazardous wastes fuel residue with high calorific value, and compared the pure pyrolysis experience results with the method of heat chemical equilibrium calculation. The heat chemical equilibrium calculation itself is an ideal process, and it is gained on the premise of presuming the materials react adequately, and it is completely different from the result gained from the real experience results. For this reason, the detailed data have no comparability, but the conclusion of the changing inmate of the pyrolysis gas components. At the same time, it proves that the heat chemical equilibrium calculation is an effective thermal prediction method for the hazardous wastes disposal. Hongxing experts calculated the equilibrium products produced in the pyrolysis, gasification and burning process of the typical hazardous wastes residue with high calorific value with different temperature and different amounts of oxygen, and do favourable provided reference basis for the design of current working conditions.cement production line: cement rotating dryer: 1. In order make sure that the materials can burn as thorough as possible and minimize the wastes, the working environment of the first burning room can be set above 0.5, and the temperature of the furnace is kept above 700?, and at the same time, the workers should make sure that adequate staying time should be remained. 2 In order to realize the goal of waste hazard-free treatment, desulfuration and dechlorination measures should be taken in the disposal process. 3 For fear of the emission of large amount of NOx, the workers can consider using the gasification working condition for the chemical reaction, and then after-burning process can be added in the second room, and the after-burning burning temperature should not be below 1100?. 4 The heat transfer amount of the furnace body under different design working condition should be analyzed according to the reaction heat release picture.
