How do you process and reuse discarded gypsum board scraps?

The waste gypsum board crushing and grinding mill production line can crush waste gypsum board and waste gypsum molds into powder for reuse. The powder can be sent to the cement factory to be used as cement retarder, or it can be sent to the gypsum powder factory for processing. Construction gypsum powder creates new ways of recycling waste and creates value.

1. How to reuse discarded gypsum molds (boards)

Every year, a large number of discarded mold plaster models, building plaster, etc. are discarded. The gypsum mold combines with water to form calcium sulfate dihydrate, which is then reduced to raw gypsum. Because the gypsum used for molding is of high quality, it can be reused. You can send it to a cement factory to be used as a cement retarder. It can be sent to the gypsum powder factory to be processed into building gypsum powder. In addition, waste gypsum mold (plate) powder can also be used as a disinfectant in garbage pools.

2. Waste gypsum board crushing and grinding mill production line

The waste gypsum board crushing and grinding machine uses a gypsum Raymond mill to crush the waste gypsum board and then grind it again to produce powder between 80 mesh and 400 mesh.

The waste gypsum board crushing and grinding mill can also process iron content and is suitable for processing coal, cement, slag and non-metallic ore powdering fields, such as cement raw materials, clinker, lime powder for power plant desulfurization, slag powder, manganese ore, gypsum, Coal, barite, calcite, cement raw meal, clinker, lime powder for power plant desulfurization, slag powder, manganese ore, gypsum, coal, barite, marble, activated carbon, carbonized coconut shell, bamboo charcoal, shells, talc, dolomite , water slag, steel slag, coal gangue, hydrated lime, zircon sand, bentonite, manganese ore and iron ore, etc.

3. Processing process of waste gypsum board crushing and grinding machine

Step 1: Crushing waste gypsum board

Waste gypsum molds (plates) are crushed using a jaw crusher until particles with a particle size of ≤15mm are fed into the Raymond mill. Use the elevator hopper to send it into the storage tank for later use.

Step 2: Feeding waste gypsum board

The waste gypsum board granular materials stored in the storage tank are quantitatively fed to the input machine through the discharge port, and are quantitatively fed into the waste gypsum board crushing mill from the input machine. An iron removal device is installed on the quantitative feeder. Remove iron impurities to avoid damaging the grinding rollers and other parts of the mill.

Step 3: Grind waste gypsum board into powder

The waste gypsum board particles fall to the bottom of the gypsum Raymond mill through the grinder inlet. They are lifted up by the base blade and enter the gap between the grinding roller and the grinding ring. The grinding roller applies pressure to grind the waste gypsum board particles into Powder.

Step 4: Grind waste gypsum board into powder

Waste gypsum board powder is collected. After the waste gypsum board is ground into powder, the hot air entering the Raymond mill is brought into the powder separator. The dust enters the dust collector through the pipe and waits to be packed into bags.

Step 5: Packaging and palletizing of waste gypsum board powder

The waste gypsum board powder installed in the dust collector enters the packaging machine (valve port or open-top packaging machine) through the discharge valve, and is then stacked by machine or manually. Waste gypsum board powder is packed into bags and ready for sale and utilization.

The waste gypsum board crushing and grinding machine is an economical investment equipment for waste utilization. Usually a production line of hundreds of thousands to hundreds of thousands can be invested to produce waste gypsum templates. Enterprises with a large amount of waste gypsum leftovers can use this equipment to create Create a new way to profit and recycle.
