Jul 13, 2021· The basic ingredients of Portland cement are lime (calcium oxide), silica, alumina, and iron. Gypsum is added to adjust the setting time. The components are heated in a kiln, and then ground to produce a fine cement powder. Most of the water used by cement plants is for equipment cooling.
Jun 01, 2016· Rotary Dryer Design & Working Principle. For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption. Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design are used.
Oil-fired rotary kiln belongs to large rotary kiln equipment. The production capacity of an oil-fired rotary kiln can reach 500kg per hour and 3600 tons per year, which is equivalent to the production capacity of 2-3 electric heating rotary kiln. Moreover, the oil fuel rotary kiln saves the production of land and reduces the maintenance work.
After calcining, the qualified gypsum powder will be sent to spiral conveyor through hoist. The spiral conveyor will send the calcined gypsum powder to silo for storage, and cool the powder during the process. The dust remover is on the top of silo, the unqualified part will be sent to grinder until it's qualified.
Then, gypsum will enter the feeding end of rotary kiln dryer. Under this situation, the inclination of feeding end will be larger than natural inclination of gypsum.then, gypsum will enter rotary kiln dryer smoothly. calcining rotary kiln is a rotary drum with certain inclination. Raw material：Phosphaste gypsum Output capacity：5-10T/H

The Komline-Sanderson Paddle Dryer and Paddle Processor are highly efficient, mechanically agitated, indirect heat transfer devices that add or remove heat from a process mass. It is used around the world for indirect drying, heating, cooling, pasteurization, crystallizing, and reacting of pastes, cakes, powders, and granules.
Turbine dryer: Drying sensitive bulk materials. The Grenzebach turbine dryer is the perfect solution for continuous drying of sensitive powder, crumbs, pastes, and flaky or lumpy products. In this process, the particles are rearranged slowly and gently, with virtually no abrasion and with minimal dust generation.
Claudius Peters' Rotary Drum Coolers can process up to 100 tonnes per hour of calcined gypsum products. The hot material is cooled via the counter-current indirect principal in whom cooling air is moved along through a bundle of tubes in the direction opposite the material flow.
Radiant heating is distinct because it warms people and objects that come in contact with it rather than just heating the air. When installed under foot, the tubing carrying the hot water is usually encased in a slab of concrete or lighter-weight gypsum cement. In some cases, the tubing can be fastened to the underside of subflooring instead.
Jul 09, 2016· (a) Calcium sulfate (CaSO4, CAS Reg. No. or CaSO4-2H2O, CAS Reg. No. 1), also known as plaster of Paris, anhydrite, and gypsum, occurs naturally and exists as a fine, white to slightly yellow-white odorless powder. The anhydrous form is prepared by complete dehydration of gypsum, below 300 deg.C, in an electric oven.
