Gypsum Powder Production Line
The
gypsum crusher machine
plays a vital role by breaking down large gypsum ore into smaller fragments of less than 30mm, which are then transported to the
gypsum powder machine
for processing. The resulting gypsum powder, once ground to the required fineness, is directed to the
gypsum making machine boiling oven
for calcination. Any material failing to meet specifications is redirected back to the
gypsum grinding machine for further grinding. After calcination, the qualified gypsum powder is either stored in a
gypsum making machine clinker container
or is forwarded to the production workshop for use.
Gypsum powder
Gypsum powder typically appears as white or colorless, translucent gypsum crystals; however, it can take on shades of grayish-yellow or light brown due to impurities.
Gypsum powder finds widespread use in various applications, including building materials, model making, ceramics, dentistry, crafts, food production, and beyond.
For gypsum powder processing, the following
gypsum powder machines
can be selected:
- High pressure suspension roller YGM Raymond mill: processing fineness between 15-425 mesh (fineness can be arbitrarily adjusted);
- HGM Medium speed superfine mill: the processing fineness is between 325-mesh (fineness can be adjusted);
- European version of the coarse powder milling machine: processing fineness of less than 3mm.
HGM Three Ring Medium Speed &#;&#;Ultrafine Grinding Powder is also referred to as the Gypsum Powder Production Line, as it encompasses multiple stages including crushing, lifting, grinding, conveying, and dust removal.
This production line is capable of processing not only gypsum but also non-flammable, non-explosive brittle materials that require ultra-fine powder, with a Mohs hardness of up to 6. This includes materials like calcite, dolomite, kaolin, talc, and many others, totaling over a hundred different types.
Working Principle of Gypsum Powder Production Line
The process of gypsum powder production entails introducing raw gypsum and desulfurized gypsum into the feed port where they encounter the outer wall of the heat exchange tube in the cylinder. The system utilizes flue gas from the boiling furnace for desulfurization. Here, the gypsum is subjected to heating and calcination, leading to the collection of the resultant product from the exhaust port. This indirect heat exchange facilitates a higher vapor pressure within the cylinder, thereby enhancing product quality. Furthermore, this method prevents direct contact between the gypsum and the heating medium, thus maintaining the product’s purity. The use of rotary calciner technology allows for controlled conversion from gypsum dihydrate to gypsum hemihydrate by managing calcination intensity. Technologies such as fluid bed furnaces create heat sources that minimize coal consumption and optimize thermal efficiency, achieving a daily output of around 100 tons—representing an ideal solution for industrial gypsum calcination.
Production Process of Gypsum Powder Production Line
The construction plaster production line typically consists of five main sections, namely: the crushing system, liming system, storage and transportation system, and the control electrical system.
1. Crushing System:
The raw gypsum material enters the gypsum crusher machine through a feeder, where it is reduced to small particles of less than 30mm. The choice of crusher depends on the size of the gypsum ore and production requirements. Common options include PE jaw crushers, PC hammer crushers, and PF impact crushers. Dust removal equipment is available for environmental compliance.
2. Transportation of Raw Materials:
The crushed gypsum materials are transferred to a storage silo for use via a hoist system which optimizes material storage time to maintain a stable supply.
3. Grinding System:
Gypsum materials enter the gypsum powder mill machine through an electromagnetic vibrating feeder for grinding. The ground powder is then propelled through the air stream created by the mill’s fan and classified through an analyzer. The products meeting fineness specifications are collected by a cyclone collector where they are processed into finished products. The entire air path system operates under a closed, circulating format, with bag filters to remove dust and maintain workplace cleanliness. Ultimately, the material transitions from 0-30mm in size to 80-120 mesh, conforming to drywall requirements.
Therefore, significant equipment in this stage includes cranes, storage containers, vibrating feeders, a gypsum mill, screw conveyors, and bag filters. The
gypsum powder making machine employs CLIRIK's advanced patented HGM ultrafine mill, featuring an internal dust separator that streamlines the process.
4. Calcination System:
This section encompasses hoists, boiling ovens, electrostatic precipitators, and Roots fans. The boiling furnace is the most common equipment utilized for building plaster calcination in the region. Its advantages encompass compact size, significant production capacity, simple structure, durability, low power consumption, and excellent product quality.
5. Electrical Control System:
The electrical control setup employs cutting-edge centralized, DCS, or PLC control mechanisms, incorporating components from well-respected international brands.
The gypsum powder making machine crushes the large gypsum ore into small particles of less than 30mm and conveys them to the for grinding. Gypsum powder that reaches the required fineness of the product after grinding is sent to the for calcination. A piece is returned to the for re-grinding until it is qualified. The calcined qualified gypsum powder is sent to the for storage or to the product workshop for use. Gypsum powder is usually white, colorless, and transparent crystals referred to as translucent gypsum, while impurities can lead to variations in color. This powder is prevalent across several industries, including construction, modeling, ceramics, dentistry, and food processing, among others. The HGM Three Ring Medium Speed Ultrafine Grinding Powder, synonymous with the Gypsum Powder Production Line, utilizes stages of crushing, lifting, grinding, conveying, and dust removal. Gypsum powder production lines can handle not only gypsum but a variety of brittle materials too, exceeding one hundred types.

STEP2. Storage Conveying System
The crushed gypsum raw material transitions to a storage unit via an elevator. The design of the storage bin reflects the requirements for material storage time, ensuring a consistent supply of materials while optimizing floor area through the use of lift systems.
STEP3. Grinding System
- The grinding process is the heart of gypsum powder production. Gypsum in the storage bin moves to the grinding machine via a vibration feeder for processing. The electromagnetic feeder situated beneath orchestras a timely supply based on the mill's running conditions.
- Raw materials are supplied into the mill uniformly and continuously for grinding.
- Milled gypsum powder is blown out by the airflow produced by the mill's blower and classified by the analytical machine mounted above the primary unit. The appropriately fine powder enters the cyclone collector as guided by airflow and is discharged through the powder outlet pipe, becoming the finished product.
- The final product shifts into the screw conveyor for transportation to the next calcining station. Air circulates through the return duct of the cyclone collector into the blower. The air path system runs under negative pressure, which encourages cleanliness as the increase in air volume resulting from water evaporation during grinding is diverted into the bag dust collector before being released into the environment.
- Post-grinding, database observation reveals a transformation from material sizes ranging from 0-30mm to a refined 80-120 mesh, adhering to gypsum powder specifications.
STEP4. Calcining System
After grinding concludes, the gypsum powder moves to the rotary kiln for calcination via the powder separator; plaster proceeds to storage while particles that don’t meet requirements cycle back to the mill. This system routinely includes lifting mechanisms, boiling ovens, electrostatic dust remediation, and Roots fans.
STEP5. Electrical Control System
The electrical setup acquires modern centralized control, DCS control or PLC, emphasizing globally recognized brand components.
