First grind and second bake. The largest advantage of this technique, compared with that of “first grind and second bake”, is energy consumption reduction. Large plaster stone shall be ground into powders with diameter less than 0.2mm, which increases the specific surface when calcining, enlarges the contact area with heat medium, improves calcination heat exchange efficiency and lowers energy consumption greatly. This equipment has small bulk, large production capacity, and simple structure and is hard to destroy.
Specifications
- The equipment is delicate and owns
- The production capacity of the ebullience calciner is essentially decided by the quantity of heat transferred by heat source through heater wall to the material. Because the material completely realizes fluidization, it is unnecessary to install blending equipment within the ebullience calciner, many heat pipes can be installed with high density so the small-size furnace shall have large heat-transfer area. Besides, the heat source adopted by ebullience calciner is saturated steam or heat oil, their coefficient of heat transfer is one order of magnitude higher than that of hot smoke.
- Structure is simple and hard to des
- Owing to the fluidization of the materials, rotating parts are not needed and the structure is much simpler, which is convenient for manufacturing and maintenance is not required after put into production. Since the low-temperature heat source is adopted, the furnace shall not be threatened by burning at all events and the equipment has a long service life.
- The equipment is compact and covers
- the ebullience calciner is standing equipment; the dust collector covers the upper furnace body and is integrated with the furnace. The equipment is quite compact so it covers small areas and avoids the dew of the dust collector
- Low energy consumption
- The heat energy consumption and electricity consumption of the ebullience calciner are low. Heat energy: as to the heat energy transferred from heat source to materials, only a small amount is used to heat the blasted cold air at the bottom of the furnace or is lost from heat dissipation of the furnace body, most heat is applied to the dehydration and decomposition of the materials. The heat efficiency of the furnace is above 95%
