One hand, cement rotary kiln is the combustion equipment,in which coal powder burns to produce heat; Another hand, cement rotary kiln is the heat transfer equipment,raw materials absorb the gas heat to burn. Fuel combustion, heat transfer and material movement must be reasonable co-ordination to make the heat produced by material burn transfer to raw material timely when raw material go through the cement rotary kiln. This can reach the high-yield, high-quality and low consumption of purpose.
Cement rotary kiln consists of two kinds of dry method and wet method.Used for wet process in the production of cement kiln wet method kiln, wet production is made from the raw water is 32% ~ 40% slurry. Due to the slurry preparation into liquid, so mix well among different raw materials, raw ingredients evenly, make the high quality of the clinker burning, it is the main advantage of the wet production. Dry-process rotary kiln and the wet rotary kiln compared advantages and disadvantages of the opposite.Dry process will be made raw powder, raw water, generally less than 1%, so it specific humidity method to reduce the evaporation heat as needed.Hollow kiln due to the high exhaust temperature, so the heat loss is not low. Dry process production will be made dry powder raw material, its liquidity worse than mud. So the bad ingredients, uneven composition. And we need to e familiar with the drawings in installation of cement rotary kiln.
Because of the cement rotary kiln is a large production equipment, so must be familiar with drawings, before the installation of the equipment through the equipment drawings to master the specific parameters of the rotary kiln equipment, understand and master the exact location of each part of the equipment, and installation position and basic line drawing. Grasp the factory each production through layout, location, water, point, road layout and equipment of the other sites, etc., to determine the transport routes, determine...
