High Aluminum Grinding Material (Ceramic ball) Production Craft Process
Cooked aluminum alum soil has been broken (rough, fine -breaking), two sections of milling, spraying, forming, drying, and burning craft process.
The specific process is described as follows:
(1) Preparation
After the cooked aluminum (block and granularity of the particle size less than 30mm) is transported into the factory, there is a raw library in the heap. The loader removes the raw material into the raw material warehouse to the broken process.
(2) The raw material crushing sieve distribution process
The clinker is sent to a jaw crusher (400 × 600) for a rough break by a closed belt, and then sent to a vertical crusher (700) for fine break, and then the closed belt is transported to the vibration sieve. Siege, the on the screen returns the vertical crusher, the lower part of the sieve enters the powder ore warehouse to be grinded, and the particle size of the clinker after the screening is less than 5mm.
(3) Rough grinding, fine grinding process
In order to reduce the product's firing temperature, a small amount of white cloud stone powder needs to be added. In order to increase the liquidity of the raw materials, a small amount of sodium trimer phosphate is needed.
According to the proportion, the white cloud stone powder and sodium trimer phosphate are referred to, and then the transfer platform is lifted by a single beam to pour the pink warehouse entrance of the transportation platform into the pink warehouse, and the aluminum soil of the powder warehouse The clinker mixes together, and then uses the electromagnetic vibration to the feeder and a closed band conveyor to make the goal grinding machine rough.
In order to increase the adhesion of the raw materials, a small amount of polyvinylisol is needed. Solk the polyethylene glycol in the hot water of 90 ° C, heat it with an electric cooker, and add the polyethylene alcohol water solution to the fine grinding machine in one hour before the mix is finely grinded into a fine grinding machine.
(4) Spray granules
The mud is pulled out of the mud pump to the jar of the spraying workshop, and then entered the 8000 type of spray spray granular tower to dry the granules from the plunger pump. Ten spray guns turned into a very small atomized pulp drip. At the high temperature of 600 ° C in the tower, the water carried by these pulp was quickly evaporated and turned into a certain granularity (7-8%) a certain granularity (7-8%). The spherical granules are dropped, and the closed belt machine is transported into the warehouse to store. The workshop has multiple warehouses at the same time.
The spray granular tower is a kind of drying equipment that produces the product after the granularity requirements are reached through the darling, dust removal, atomization, and solidification of the material. The process process is generally the air of the air through the heating device and enter the bottom of the fluidized bed, passing through the distribution board to contact the material, making the material become darling. The maternal liquid or adhesive is sent to the atomized nozzle by pressure pumps such as pressure pumps. After atomization, coat on the surface of the fluidized particles or make the particles bond each other. Large discharge from the moisturizing bed after reaching the required particle size.
(5) Molding
After drying the powder, the powder is transported from the closed belt to the molding workshop, and directly enters the automatic static and other compressors. The automatic static and other compressors set the material, feed, mold, and suppress it in integration. The pressed billet material is placed artificially to the kiln car, and the post -segment process is dried and burned.
(6) Drying and burning
The self -forming workshop is transported by a kiln car with a blank material to send the dried kiln to dry by the moving push rod. The remaining heat recovered, the wet air after drying is directly discharged.
After drying, the kiln car is sent to the high -temperature tunnel kiln or roller kiln to burn. A total of 3 days will be used to complete the preheating, firing, and cooling process in the kiln. The temperature of the flue gas temperature in the preheating area is controlled at 400 ° C to 500 ° C, and the maximum control of the flue gas in the firing area is 1000 ° C to 1600 ° C. The temperature of the flue gas in the cooling area is controlled at 200 ° C to 1300 ° C. The products that are burned by tunnel kiln or roller kiln are manually loaded and unloaded to the finished database.
After the above complex procedures, our high -quality aluminum grinding ball is made.
