The steadily increasing demand for powders of plastic, rubber, or minerals of any kind as well as the constantly expanding quality requirements with regards to flow ability, bulk density, particle size distribution and grain structure, call for pulverizing systems of most modern technology. BOGDA offers complete standard and custom systems developed and proven in practical applications.
The cryogenic grinding system is using Liquid Nitrogen as cooling method. The material will be bumpered into powder at it's glass embrittlement point through the LN2 cooling.
At normal temperatures, tough and elastic materials can not be ground to a fine grained powder, even when the grinding media are run at high speed. With "Cool" Grinding, however, the use of liquid nitrogen render the material brittle prior to the cool grinding stage, with the effect that platics and rubber granulates, etc. can now be grounded to a fine, easily-folowing power.
Advantage of Cryogenic ultrafine powder freezing Pulveriser compare with normal pulveriser
1-Optimal retention of aroma and strength, in contrast to normal pulverizing, where between approx 15 & 43% essential oils are lost, while the loss with cryogenic grinding is minimal (approx. 3-10%)
2-Output is 2-3 times than that of normal pulverizing
1-chemical, coating areas: metal wall coating areas: Teflon, PA, PC, PU, PP, PE coating powder; Plastic coating: stick coatings on high combination of paint; mute coating:
Elastomer nano-absorbing coating; anti-corrosion coating; absorbing coating materials such as the use of ultra-fine grinding. Reached the international advanced level in the primary crushing process (natural masterbatches crushed) on.
2-food, health care products: fruit crushing plant, animal and plant extracts, medicine, natural, synthetic elements to ensure its original elements are not lost in the crushing and drying process.
3-recycling areas: low melting plastic, high self-lubricating materials, waste rubber, cryogenic grinding raw collagen gel way.
General food at minus 10-15 degrees can crush crushed to 200 mesh or more.
Plastics can be crushed to about minus 30 degrees .
Mechanical use of microcomputer control host for the amount and the amount of nitrogen available. According to customer needs to set the microcomputer control system automation level, the user only needs to set a parameter point fineness values, intelligent control system based on the basis of this argument points to the host current, local chamber pressure, pipe flow, material temperature automatically adjust the power of each frequency point, the refrigerant valve size, air compensating valves, discharge rate, heating systems, etc., to achieve intelligent control.
Cryogenic freezing pulverizer configuration:
2-Main pulverizing motor:Siemens
3-Material:must be all SUS304 stainless steel
4-Three big motors: Grinding motor, Adjustment motor, Traction motor(recycling liquid nitrogen and reducing the energy consumption);two small motors: feeder motor and discharge motor.
How does cryogenic freezing pulverizer work?
This deep cold pulverizer system takes liquid nitrogen as cold source and use the brittleness of the stuffs under cold temperature.When the cold brittle stuffs enter into the pulverized through the integrated effect of mutual repeat impact,collision,shearing,rubbing between stuffs and stuffs,stuffs and vane,stuffs and gear plate.
The stuffs after pulverization will be classified and collected.the particles which haven’t
reached the size requirement will be returned back to the bin and pulverized again.most of the cooling air will be also recycled.
