Cold grinding facilitates efficient PVC recycling - Gases,

At the heart of the recycling process is cold grinding. The coarsely crushed plastic residues, or granulates, are cooled to minus 120 degrees Celsius in a Messer precooler using injected liquid nitrogen. At such low temperatures, the PVC becomes as brittle as glass. It can be ground to a fine powder without it sticking together or going lumpy.Pvc Liquid Nitrogen Cooling Plastic Pulverizer - Buy,,Pvc Liquid Nitrogen Cooling Plastic Pulverizer ,,Apply liquid nitrogen as grinding medium, achieve cryogenic grinding, anti-explosion, anti-oxidation etc effect. In the pulverizing system, the cold source forms a closed cycle system, which makes full use of energy and saves energy.China Liquid Nitrogen Cooling Plastic Pulverizer,Freezing,,This Cryogenic Pulverizer using liquid nitrogen to lower the input material temperature to material embrittlement condition firstly, then go to the grinding chamber, the input materials were thoroughly pulverized through blade wheel’s high speed rotating, and the comprehensive force like mutual repeatedly impact, crash, shear and friction between the materials and blades, fluted disc,

Cryogenic grinding: an independent voice

Grinding processes using liquid nitrogen fall into two types: temperature-controlled grinding and true cryogenic grinding. In the first type, the liquid nitrogen is injected directly into the mill, where it acts as a heat transfer medium rather than a refrigerant. Liquid nitrogen injection rate is controlled by a sensor thatgrinder for industial for grinding pvc materials,Plastic Grinding Stockbridge Plastics.
