Introduction:
Gypsum rotary kiln is the core equipment of the industrial by-product gypsum drying and calcining system, which is widely used in gypsum, fly ash, slag, food and other fields. Compared with the rotary kiln whose heat source is coal-fired (which requires larger blasting and phoenix-inducing systems, consumes more electricity, pollutes the environment, and increases the cost of burning coal and the cost of post-processing of flue gas), the steam rotary kiln can reduce the The production cost is an environmentally friendly equipment for drying and calcining gypsum, an exclusive industrial by-product.
Features:
(1) The pipeline of the gypsum rotary kiln is high pressure steam, and the low temperature and slow heat exchange is adopted, the heat exchange area is large, the temperature of the heat exchange medium is more constant, and the calcination process is easier to control.
(2) The gypsum rotary kiln has a large volume, large processing capacity, more sufficient drying and calcination, and more stable products.
(3) According to the use of the product, by adjusting the speed of the rotary kiln and the amount of steam, the initial setting time of the gypsum powder can be adjusted and controllable.
(4) The one-step method simplifies the process, drying and calcining are continuously completed in the same equipment, the control is simple, and the supporting equipment and control links are reduced.
(5) It is well used in one-step calcination and two-step drying systems, with stable production capacity and simple and reliable operation. It can be used as a one-step drying and calcining integrated production equipment, and can be used independently as a two-step high-efficiency drying equipment.
Main Technology(Nature gypsum rock)
Gypsum mine - crushing - grinding - calcining - aging -finished products (plaster of paris)
a. Crushing, Grinding Section
The forklift driver removes the gypsum ore from the quarry into the hopper in front of the crusher, and then the gypsum ore is crushed into the 20mm materials, which are later sent to the mill by the hoist to be grinded into qualified gypsum powder (raw gypsum).
b. Calcining Section
The grinded gypsum powder is lifted into gypsum calcining machine for calcination. The calcining machine uses gas heat conduction oil furnace, however, other fuels like coal, methane, LPG, diesel oil, heavy oil, etc. can also be used. Due to its low temperature, slow burning calcining mode, the stability of gypsum quality is well ensured.
c. Finished Product Packing and Storing Section
Calcined gypsum powder is lifted into the finished product silo through a hoist, where an automatic weighing and packaging machine is used to pack 50kg gypsum powder per bag for marketing or storing.
Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process.
Materials produced using rotary kilns include:cement, lime, refractories, metakaolin,titanium dioxide,alumina,vermiculite,iron ore pellets, zinc oxide,gypsum, etc.
Gypsum rotary kiln structure:
Plaster rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and combustion.
Working principle of gypsum rotary kiln:
The rotary 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-curre
Application of gypsum:
Gypsum board is primarily used as a finish for walls and ceilings, and is known in construction as drywall, sheetrock or plasterboard.
Gypsum blocks are used like concrete blocks in building construction.
Gypsum mortar is an ancient mortar used in building construction. Plaster ingredients are used in surgical splints, casting moulds and modeling.
