The complete set of gypsum powder equipment mainly includes crushing,grinding,calcination,transportation,packaging and other processes.Depending on different production scales and technical requirements,the equipment configuration and process may vary.The following is a detailed analysis of key equipment and processes:
1、Core equipment composition
Crushing equipment
Jaw crusher:used for primary crushing,crushing gypsum ore to≤25mm.
Cone crusher/impact crusher:secondary fine crushing to ensure uniform particle size of raw materials.
Grinding equipment
Raymond mill/vertical powder mill:Grind gypsum to 80-2500 mesh,matched with a classifier to screen qualified fine powder.
Ball mill:suitable for high fineness requirements,but with high energy consumption.
Calcination equipment
Boiling furnace(fluidized bed calcination furnace):Efficient dehydration is achieved through fluidized bed technology,with a single unit hourly output of up to 60 tons.
Rotary kiln:suitable for high humidity raw materials(such as desulfurization gypsum),with more precise indirect heating and temperature control.
Auxiliary equipment
Pipe chain conveyor:Automated conveying of gypsum powder to avoid dust pollution.
Pulse dust collector:Dust recovery rate≥99%,in compliance with environmental standards.
Automatic packaging machine:supports bag/barrel packaging,with a production capacity of 1-50 tons/hour.
2、Typical production line configuration
Small and medium-sized production line
Equipment:Jaw crusher+Raymond mill+Boiling furnace+Pulse dust collector,with a production capacity of 5-20 tons/hour.
Features:Low investment(about 100000 to 300000 yuan),suitable for the production of building gypsum powder.
Large scale automated production line
Equipment:Cone crusher+vertical mill+rotary kiln+DCS control system,with a production capacity of≥50 tons/hour.
Features:Reduce energy consumption by 40%,support remote monitoring and fault warning.
3、Equipment selection suggestions
Raw material characteristics:Natural gypsum needs to be roughly crushed,and industrial by-product gypsum(such as desulfurization gypsum)needs to be pretreated.
Environmental requirements:Priority should be given to using enclosed conveying and high-efficiency dust removal equipment.
Energy consumption control:Vertical mills save 30%to 50%more energy than ball mills.
4、Market reference price
Small complete equipment:about 10000 to 50000 yuan(such as mixer+packaging machine).
Annual production line of 60000 tons:approximately 500000 to 1 million yuan(including DCS control system).
