Gypsum powder

Gypsum powder is usually white, colorless and transparent crystals called translucent gypsum, sometimes grayish-yellow, light brown, and other colors due to impurities.

Gypsum powder is widely used in building materials, model molds, ceramics, dentistry, crafts, food, and other fields.
 

For gypsum powder processing, the following

gypsum powder machines

can be chosen:

• High pressure suspension roller YGM Raymond mill: processing fineness between 15-425 mesh (fineness can be arbitrarily adjusted);
• HGM Medium speed superfine mill : the machining fineness is between 325- mesh (fineness can be arbitrarily adjusted),
• European version of the coarse powder milling machine has a machining fineness of less than 3mm.

HGM Three Ring Medium Speed &#;&#;Ultrafine Grinding Powder is also called Gypsum Powder Production Line, mainly because it includes processes such as crushing, lifting, grinding, conveying and removing dust.
Gypsum powder production line can not only process gypsum, but also non-flammable and explosive brittle materials ultra-fine powder with medium and low hardness, Mohs hardness &#;6, such as calcite, gypsum, limestone, dolomite, carbon black, kaolin, bentonite, talc, celestite, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alumite, graphite, fluorite, rock phosphate, potassium ore, pumice stone and more than 100 kinds of materials .


 

Working Principle of Gypsum Powder Production Line

The working principle of gypsum powder production is to add raw gypsum and desulfurized gypsum from the feed port and make effective contact with the outer wall of the heat exchange tube in the cylinder. The flue gas from the boiling furnace is used as a means for desulfurization. the gypsum is heated and calcined and the calcined product is collected from the exhaust port. Due to the indirect heat exchange, a higher partial vapor pressure can be achieved in the cylinder, which has a positive impact on the quality of the product.In addition, the plaster does not have direct contact with the heating medium, which it retains in greatly purity. of the product. Indirect heat exchange rotary calciner technology can effectively control gypsum removal from gypsum dihydrate to gypsum hemihydrate by strictly controlling the intensity of calcination. The main technology used in this process is the use of a fluid bed furnace to provide a heat source, which can greatly reduce coal consumption and make the most of the heat. The daily output is 100- tons, which is the ideal equipment today. industrial gypsum calcination process.
 

Production Process of Gypsum Powder Production Line

According to the process requirements, the construction plaster production line is generally divided into five parts, namely the crushing system, the crushing system, the liming system, the storage and transportation system and the control electric.

1.  Crushing system:

Gypsum raw material enters gypsum crusher machine through feeder, and crusher crushes large gypsum ore into small particles less than 30mm for use. According to the size of gypsum raw materials and different production requirements, you can choose a crusher with corresponding specifications, generally PE jaw crusher, PC hammer crusher or PF impact crusher, etc. To protect the environment and clean, it can be equipped with dust removal equipment to meet environmental protection emission requirements.

2. Transportation of raw materials:

The crushed gypsum raw materials are transported to the storage silo for use by means of a hoist. The storage container is designed in accordance with the material storage time requirements to ensure a stable supply of materials.

3. Grinding system:

Materials are fed uniformly and continuously into the gypsum powder mill machine through the electromagnetic vibrating feeder for grinding. The ground gypsum powder is blown out of the air stream by the gypsum grinding mill machine fan and classified by the analyzer above the host. The fineness of the powder meets the specifications, enters the cyclone collector with the flow of the wind, and is discharged through the powder outlet tube after being collected to become the finished product. The finished product falls into the screw and is transported to the next calcination plant. The entire air path system is closed and circulating. The bag filter is inserted through the tube between the large cyclone collector and the fan to remove the dust in the air, and then discharged to the environment to ensure that the environment is clean. The material that goes through the crushing system ranges from 0-30mm grain size to 80-120 mesh, which meets the fineness requirements of drywall.

The main equipment for grinding is the crane, storage container, vibrating feeder, gypsum mill, screw conveyor, bag filter, etc. The gypsum  powder making machine adopts CLIRIK's new patented HGM ultrafine mill. Since the mill has a dust separator inside, there is no need for an external dust separator, which simplifies the process.

The size and specifications of gypsum ores are different after mining, and the applicable crushing equipment is selected for preliminary crushing treatment according to the actual situation, and the particles with particle size not greater than 35mm are broken.

STEP2. storage conveying system

The crushed gypsum raw material is transported to the storage bin by the elevator. The storage bin is designed according to the requirements of the material storage time to ensure the stable supply of materials. At the same time, all parts of the material turnover are using lifts to reduce the floor area.

STEP3. grinding system

• The grinding process is the core process of gypsum powder production. The gypsum raw material in the storage bin enters the grinding machine through the vibration feeder for finishing. The electromagnetic vibration feeder is set under the storage bin, which is interlocked with the mill to adjust the supply of materials in time according to the running condition of the mill.
• The material is uniformly and continuously fed into the mill by the electromagnetic vibration feeder for grinding.
• The pulverized gypsum powder is blown out by the air flow from the mill blower and graded by the analytical machine above the main engine. The powder with the fineness meeting the specifications enters the large cyclone collector with the air flow, and is discharged as the finished product through the powder outlet pipe after collection.
• The finished product falls into the screw conveyor and is transported to the next system for calcining. The air flow flows from the return duct of the cyclone collector into the blower. The whole air path system is closed circulation and flows under negative pressure. Due to the water contained in the ground raw materials and the evaporation into gas during the grinding process, resulting in an increase in the air volume in the circulating air path, the increased air volume is introduced from the pipe between the large cyclone collector and the blower to the bag dust collector, and then discharged into the environment to ensure that the environment is clean.
• The particle size of the material through the grinding system is changed from 0-30mm to 80-120 mesh, which meets the requirements of the fineness of gypsum powder.

STEP4. calcining system

After grinding is completed, the pulverized gypsum powder is sent to the rotary kiln for calcining by the powder separator, the plaster of Paris is sent to the storage storage by the elevator, and the materials that do not meet the requirements are continued to be returned to the mill for grinding; The system mainly includes lifting machine, boiling furnace, electrostatic dust removal, Roots fan and other equipment.

STEP5. electrical control system

The electrical control system adopts the current advanced centralized control, DCS control or PLC control, and the control components are selected internationally well-known brand products
