Natural Gypsum Powder Production Line

The crusher breaks the big sized gypsum Ore into small ones with 25mm in diameter. After storing and conveying, they are taken into the mill for grinding. Then the powder concentrator carries the gypsum powders which match to the needed fineness to calciner for calcining. Others are back to the mill until it is qualified. In the end, after calcining, the qualified gypsum powder are sent to clinker container for storing. Ore are sent to the manufacturing workshops for use
Craft Introduction of Calciner

The demand of gypsum power is increasing with the development of gypsum industry. The manufacturing process of gypsum powder has been improving in order to cater for the market. Calcination, the hardest to grasp, is key link in the product and process of gypsum power. We develop new generation dehydrating equipment calciner that is good at the production for all kinds of gypsum powder.

1, Working principle

The main working principle for calcining system, of calciner

The main body of calciner consists of fine diameter intensive radiator pipes. Thermal oil fed into the coil pipes. The heat releases into power by heat exchanger. Roots blow installed at bottom of calciner for putting the cooling air into furnace by grid plate. the cooling air blows gypsum power in furnace for reaching boiling state. at certain temperature , the calcined gypsum power will lighten, and flow automatically to outlet. this type gypsum power is state in quality. it is easier to control the content of free water ,initial and final setting times.

3, Low energy consumption

Calciner consumes less electric energy and heat energy

Heat energy(transfer to material from heat source): almost all of the heat energy efficiently served as dehydration for materias.only little is scattered by the calciner body, and used to heat the cooling air from the bottom of the fluidized oven. The heat efficiency of fluidized oven

N itself is above 95%.of course,calciner uses secondary energy. that is , the final heat efficiency is not the heat efficiency of fluidized oven itself. It is the heat efficiency of fluidized oven itself multiplying the heat efficiency of other boiler. However, the steam boiler or thermal oil furnace has higher heat efficiency as widely used thermal equipment. Normally steam boiler is 60-70 %. In addition, normally the thermal oil furnace is up to 70-80%.(our company adopts organic thermal oil furnace).

4.Good product quality/ideal compositions/stable property

The phase transition of gypsum is stable because we adopt low-temperature heat source. finish product is nearly no raw gypsum, anhydrous gypsum only less than 5%, and the rest is semi-hydrate gypsum if the discharge temperature is suitable. The composition is ideal and physical performance is very steady.

Our company developed completely set of producing and processing kills on fluidized oven for satisfying the requirements. We adopt qualified steel as main material. For example, we adopt seamless steel tube(GB3087-82) as thermal oil pipes; we adopt special carbon steel plate and low alloy steel plate(GB 712-86) for oven; we adopt GB products on frame steel.

Moreover, the welding operators qualify for working. Avoiding the leakage of thermal oil after completing weld, we test the water pressure of coil pipes. The equipment is qualified once no leakage for a period of no less than 24 hours when the water pressure is up to 0.8-1.0 MPa.
