gypsum / plaster of Paris powder production line
is composed of crusher, Raymond mill, lifter, dust remover, heat conductive oil furnace, Roots fan, material bin etc. And the system of boiling and calcination is the key link of the whole gypsum powder-making process.
With the development of gypsum industry, the need for quantity and quality of gypsum powder is increasing rapidly. At the same time, the proceeding for producing gypsum powder had enhanced gradually
The main composition of gypsum is dehydrate gypsum CaSO4.2H2O. However, the gypsum powder used in practical production (such as the gypsum powder for gypsum board, for mould, for plastering) is to dry and dewater the dehydrate gypsum, reduce the content of crystallization water in it, so the standard of crystallization of gypsum powder can meet the needs of all kinds of gypsum powder, because it can change into plaster of pairs. Plaster of pairs can re-integrate with water when it is applied into production, and it can be processed into new type building materials with a high intensity, such as gypsum board, gypsum block, etc.

Note: The specifications above is just for your reference, plz kindly tell us your needing capacity per hour or day or year, and we will design the production line for you!
Jaw crusher
1. Jaw Crusher is of various types;
2. Jaw Crusher is suitable for crushing maximum, medium and minimum stones
3. The operating principle of Jaw Crusher is easy to be operated
4. The structure of Jaw Crusher is simple and it is easy to maintain
Gypsum grinder Raymond Grinder
Raymond Mill is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements.
New-type gypsum frying boiler- ebullience calciner
First grind and second bake. The largest advantage of this technique, compared with that of “first bake and second grind”, 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 calcinations heat exchange efficiency and lowers energy consumption greatly. This equipment has small bulk, large production capacity, and simple structure and is hard to destroy.
Electrostatic dust collector
itworks is to use of high-voltage electric field to ionize the flue gas, charged dust in the air flow in the electric field and the flow separation. , Called the discharge electrode, a negative electrode is made by the different cross-sectional shape of the metal wires. The positive electrode is made of a different geometric shape of the metal plate, called the collecting electrode. Electrostatic precipitator performance by the three factors of the dust characteristics, device structure and the flue gas flow rate. The specific resistance of dust is to evaluate the conductivity indicators, and its removal efficiency has a direct impact. The specific resistance is too low, dust is difficult to maintain on the collecting electrode, resulting in its return to the stream. Specific resistance is too high to reach the dust charge of collecting electrode is difficult to release, in the voltage gradient is formed between the dust layer will produce a partial breakdown and discharge phenomenon. These conditions will result in the removal efficiency decreased.
Heat-conducting oil boiler
Main characters:
1. High automaticity, prompt start and stop, high reliability.
2. High thermal efficiency, completely burning, stable output, better adaptability to variable load.
3. Compact structure, small area requirement.
4. Less auxiliaries, easy installation.
5. Less pollutant emission, can reach higher Environmental protection index.
Electrical control system
The current advanced DCS(distributed control system) is selected for the electrical control system, and the PLC is chose from Japan’s Mitsubishi company, which could centralized control equipment that scattered in different parts. It becomes the first choice for modern building industry due to low labor, cost and high efficiency.
Advantages of gypsum powder production line:
1. We have built many lines for oversea company, such as Columbia, Uzbekistan , Mexico, Italy, USA, etc;
2. Use hot oil or natural gas technology;
3. Supply top-quality machines and good after-sale service;
4. Can design all capacities you want;
5. Fully automatic operation.
Besides the equipment mentioned above, design for the entire production line and auxiliary equipment election are provided, and technical engineers would be sent to the customer’s site for installation and debugging machine to guarantee qualified product.
