Gypsum powder, as an important building material and industrial raw material, has a wide variety of processing equipment, covering the entire process from raw material processing to finished product packaging. The following is a detailed classification of core equipment for gypsum powder processing:
1、 Crushing and shaping equipment
Raw gypsum needs to be crushed before further processing, and the main equipment includes:
Jaw crusher: undertakes coarse crushing tasks and can crush large gypsum blocks to below 50mm
Cone crusher: for medium and fine crushing operations, with a production capacity of 80-150 tons/hour
Counterattack crusher: suitable for shaping medium hardness gypsum, with excellent particle size in the finished product
2、 Grinding equipment system
The key process is to grind the crushed gypsum to the required fineness:
Raymond mill: a conventional grinding equipment with low energy consumption and a fineness of up to 325 mesh
Vertical milling machine: preferred for large-scale production, with an hourly output of up to 30 tons
Ultra fine grinding machine: a professional equipment for producing ultra-fine gypsum powder with a mesh size of 1250 or above
Ball mill: Processing high hardness gypsum, matched with grading machine to achieve fine grading
3、 Calcination equipment system
Controlling the degree of gypsum dehydration determines product performance, and the main options are:
Fryer: Traditional intermittent calcination equipment, suitable for small-scale production of special gypsum
Rotary kiln: continuous production equipment with high degree of automation, suitable for large-scale production
Boiling furnace: fluidized bed calcination technology, with a thermal efficiency of over 75%
Sleeve kiln: a new energy-saving equipment that can accurately control the calcination temperature curve
4、 Auxiliary processing system
The supporting equipment to ensure product quality is equally important:
Pulse dust collector: captures dust generated from grinding and calcination, with an emission concentration of<30mg/m ³
Boiling cooling machine: Quickly cool the calcined gypsum powder to prevent overburning
Automatic packaging machine: achieves quantitative packaging of paste and powder, increasing efficiency by more than 60%
Modern gypsum powder production lines often adopt modular design, and equipment selection needs to comprehensively consider the characteristics of raw materials, product uses, and production capacity requirements. Reasonably configuring core equipment such as crushing, grinding, and calcination, and supporting efficient environmental protection facilities, can build a modern production system with stable operation and controllable quality.
