Following is the brief introduction of the gypsum production technology and ebullience calciner working principle.The Crusher will break the big-size gypsum ore into small 25mm pieces, and then the small pieces will be sent to the grinder, after grinding fine, the qualified raw gypsum powder will be sent to boiling furnace to calcine, and the unqualified part will be sent to grinder until its qualified. 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 its qualified. The stored gypsum will be sent to product storage through steel impeller feeder, spiral conveyor, hoist, and send the qualified gypsum powder to storage or workshop finally. The top pulse bag stype dust remover will collect dust from crusher, particle silo. When the dust and dust gas get into the dust remover through inlet, the big-size dust particle will fall because the increasing size and decreasing wind speed. The small dust particle will be filtered by filter bag. The filtered gas will be got rid of by outlet. Feel free to contact douwentao8888 at hotmail dot com

building gypsum powder production line - buy building gypsum powder production line, gypsum powder machine, grinding machine product on guilin hangda mining machinery co., ltd

Gypsum, a monoclinic mineral, is a hydrate of calcium sulfate CASO42H2O. Gypsum is a kind of widely used industrial material and building material. Gypsum has natural gypsum and chemical gypsum, can be used in cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler, paint filler.

The natural gypsum raw material is put into the rotary kiln and calcined at the temperature of 107 C ~ 170 C.The finished products made in the rotary named Plaster of Paris.After aging further, the Raymond Machine will grind the plaster of Paris into 200 Meshpowder.This powder,that is, building gypsum powder (commonly known as plaster of Paris). The main components of building gypsum powder is type hemihydrate gypsum (Caso4 1 / 2H2O).

Building Gypsum Powder has good heat insulation sound absorption performanceBuilding Gypsum also has good fire absorption performance after hardening.The Colorof building gypsum is white. Itcan be used for indoor painting construction, especially suitable for making a variety of. White, smooth and delicate flower decoration, the addition of pigments in gypsum powder can make products have a variety of colors.

According to the technical requirements, building gypsum production line is usually divided into five gypsum powder machines parts. They are crushing system, calcining system, grinding machine system, packaging system and electronic control system.

The gypsum material is shoveled into the raw material hopper by a forklift.Then,the vibrating feeder at the lower part of the raw material hopper feeds the material uniformly into the crusher. And then, the crusher breaks the large-sized gypsum ore into small pieces of particles smaller than 8 mm. At the same time, the elevator and bracket machine transport the mineral materials to raw material warehouse. According to the size of gypsum raw materials and different output requirements, you can choose the corresponding specifications of the crusher. In order to protect the environment , the crusher can be equipped with dust removal equipment. The general operation of this section is 8-10 hours. storage bin according to the requirements of material storage time design specifications, to ensure a stable supply of materials, to meet the calcination system 24 hours of operation.

Ore material come from thestorage bin will go to the silo before the rotary by impeller feederscrew conveyorand elevator. After that, the belt will take the mineral materials into the rotary for calcining. When calcining,the pulse bag dust collector in front of the rotary will collect the steam generated bycalcining ;

Then,the crushed coal will go to the coal silo in the front of the fluidized bed furnace. And next,the impeller feederwill send the coal into the furnace chamberfor fully being burned.The rotary kiln shell is heated, and the gypsum material is calcined through the shell conduction, the flue gas from calcination is collected by a water desert dust collector. The calcined cooked powder is transported to the semi-finished product bin by a hoist to be aged.And generally,it is aged for about 20 hours. The material is continuously dehydrated and homogenized in the aged Bin, so as to ensure the good stability of the cooked gypsum powder.

The fluidized bed furnace is the most widely used gypsum calcination equipment in China. It has the following characteristics: small equipment, large production capacity, simple structure, not easy to damage, compact equipment, less land, low energy consumption, easy operation, easy to achieve automatic control, good product quality, relatively ideal composition of plaster of Paris, stable physical performance, the capital construction investment is small, the running cost is low and so on. This system is widely used in the calcination of natural gypsum and chemical gypsum.

The method of Rotary Kiln calcining the gypsum can be divided into two types. The inside burning type and the outside burning type. The internal combustion type uses natural gas as fuel. The external combustion type uses pulverized coal as the fuel.

The finished powderfalls into the elevatorand is transported to the next system package section. The air flow flows from the return air pipe of the large cyclone collector to the blower. The whole air path system is closed circulation and flows under negative pressure. As the ground material contains water and evaporates into gas during the grinding process, the air volume in the circulation wind path increases. The increased air volume is introduced into the bag filter from the pipe between the large cyclone collector and the blower, remove dust from the air and release it into the environment to ensure a clean environment. The material after grinding system changes from particle size 0 ~ 8mm to 80 ~ 200 Mesh, which meets the requirement of fineness of gypsum powder.
