Whether grinding complete bales or using a guillotine for a more consistent feed, our equipment and systems are well established to solve this difficult application. In the last 50 years, Hosokawa Polymer Systems has continually evolved and …

genic grinding. This involves grinding aids such as liquid nitrogen (-196 °C) or dry ice (-78 °C) which embrittle the sample by cooling and make it break more easily. Another advantage is the preservation of volatile components of the sample. In this white paper we explain for which sample materials cryogenic grinding is

In case of cryogenic grinding, one phase normally suffices for reaching the requested separation of the components and obtaining a broad particle size spectrum of rubber crumb. A disadvantage of this technology is the high cost for the use of liquid nitrogen, since one to two tons of LN2 are required for one ton of waste tyres.

recommend our energy-efficient wet grinding method. This technique allows the production of powder in the sub micron level range. Today, wet mills such as the AHM produce metal powder – processed in solvents – in the nano-level range. Many products do not only have to comply with a predefined fineness level but also have to meet

Processors of heat sensitive products such as polymers, caoutchouc, elastomers and foodstuffs now have the option for cryogenic ultra-fine grinding with a milling system incorporating the proven capabilities of the Hosokawa Alpine Contraplex 160C, a contra-rotating pin mill, available from Hosokawa Micron Ltd.

This plastic dust can clog filters, bridge over extruder throats, cause burn marks, dimples and other part defects. Hosokawa Polymer Systems makes many types of fines separation and dust separation equipment to remove this …

The spices are cooled with liquid nitrogen, which freezes the oily-fatty constituents, and the original aroma of the freshly harvested spice is fully preserved. 1 Contraplex fine impact mill 250 CW cryogenic milling system 2 Plate beater unit of a fine impact mill 1250 UPZ

adhesives, PVC, polyester, caoutchouc and rubber, etc. In the foodstuffs industry, cryogenic milling is used above all to grind spices. It is possible with cryogenic milling to improve the aroma by reducing the loss of essential oils (approx. 3 to 10% loss) in comparison to milling at ambient temperature (approx. 15 to 43% loss).
