Cement Plant, Quicklime Plant.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica bearing minerals toform a mixture of calcium silicates. Cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type cement production line. This equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln. 1. Supporting device: advanced shaft structure, automatic temperature measuring device and electrical heating. 2. Catch wheel: including two kinds mechanical wheel and hydraulic pressure. 3. Gears: single or double. Control the rotating speed by buncher, DE machine and frequency variable motor. Be reliable, energy-saving, and efficient. 4. Cylinder tire bolster: lower bolster has three types: fixed, zoom and floating. The structure is simple, replacement is convenient and won’t hurt cylinder. 5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The sealing effect is very good. 6. Kiln head hood: including stationary type and flexible type. comment:we can also custom rotary kiln spare parts, just like rotary kiln tire,gear..and so on.
The rotary kiln is a cylindrical vessel, inclined slightly to the horizontal. The material is fed into the upper end of the cylinder. As the kiln rotates, the materials gradually move towards the lower end, and they may go a certain amount of stirring and mixing. Hot gases go through the rotary kiln, in the same direction as the process material, but usually in the opposite direction. The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. They are repetitively scattered in the air so that they are in full contact with the hot air, the material is dried gradually.
