The Operation Principle of Rotary Kiln

There are two types of cement kiln-dry process cement kiln and wet process cement kiln-that mainly used to calcine cement clinker. Metallurgical and chemical kiln is mainly used in metallurgical industry, refractory plant and chemical factory. The structure of Cement rotary kiln, operate conveniently and reliably in life, less wearing parts, high rate of operation, it is the equipment to calcine high-grade cement in cement plant.Features of Rotary Kiln
Principle of Operation
The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or “firing pipe”) which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal.
Zhangzhan, executive director of China nonmetallic ore industry association, has promoted a proposal that opportunities belongs to the preparative nonmetallic industry to the industry. Hongxing machinery ,concentrates on the research and development of micro powder grinding equipment for many years, responses to the nation’s development of nonmetallic ore and develops HGM series mill, three ring intermediate speed super fine pulverizer that apply in the grinding of fluorite, bauxite, kaoline and other ores. Those equipments are popular in the market.
 Sand production line can design break ground sand in allusion to the hard pebbles, rocks, etc. and multi-stage crush with different crushing machines in allusion to different particle sizes. And the flexible and cycled production process ensures highly efficient operation of the system.
