2024 Whole Set Gypsum Powder Manufacturing Plant with Annual Output 100000 tons

2024 Whole Set Gypsum Powder Manufacturing Plant with Annual Output 100000 tons

Introduction of the gypsum powder production line:

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.

The quality of building gypsum is in accordance with Chinese National Standard "gypsum powder"(GB9776-2000),and should meet the following requirements:

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!

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.

The working principle of ebullience calciner

The main part of the ebullience calciner is composed of small-diameter cooling coil pipes. The heat transfer oil is piped into coil pipe and releases the heat into the furnace after exchanging heat. Roots blower is equipped at the bottom of the ebullience calciner, which can blow the cold air into the furnace, making the powder boiling in the furnace. And at certain temperature, the powder, which has been dried, becomes light that it can flow to the outlet automatically. The quality of the gypsum powder produced in this way is better and the content of crystallization water is high, and easy to control the time of solidification. In addition, the machine is equipped with dry electrostatic precipitator , and the dust removal efficiency reaches over 95%, eliminating the dust pollution.

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.

B esides 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.
