Granulator in chemical industry is widely applicable to the melting point (softening point) at 300 ℃, various materials for condensing granulation. Such as: sulfur, paraffin wax, rosin, pitch, stearic acid, trimellitic anhydride, maleic anhydride; phenolic resin, petroleum resin, modified resin and other resin products; hot melt adhesive, synthetic detergent, urea, additive, rubber and plastics additives and other products.
Granulating machine according to the structure and working principle and divided into CF type rotary belt condensation granulators flat twin screw extruder drying drum roll production machine dry granulator (referred to as the roll granulator) on tooth granulator disk vacuum condensation granulators etc.. Below are the details about the characteristics and the use of a dry granulators.
The dried powder raw materials from the top of dry granulator, pre compressed into a rolling machine, rolling machine in the double squeeze, the material into a sheet, the sheet material after crushing, whole grain, screening process, need to obtain granular products. Material by mechanical compression molding, does not destroy the chemical properties of the material, decrease the effective content of product. The production process automation, suitable for mass production. The whole process of the whole seal, no impurity influx, the purity of product is high, and the product has no pollution to the environment. Dry granulating machine complete sets of equipment, all parts contacting material, all stainless steel or titanium alloy steel, anti-corrosion performance is very good.
Dry granulator is applicable to cyanuric acid, two chloro isocyanuric acid sodium, three chloro isocyanuric acid sodium, zinc oxide, lead oxide, titanium dioxide, electricity jade powder, melamine powder, potassium nitrate, white carbon black, sodium two, five sodium, magnesium carbonate, barium carbonate, strontium carbonate, ammonium chloride, potassium chloride and other chemical products and pharmaceutical raw materials, granulating civilian feed, various pigment granulation.
Dry granulating machine on the export of chemical powder, granule can meet the requirement of export in transport, the use of the process, reduce the pollution of the environment, enhance the mobility of the material, the strength of the particles can be arbitrary regulation, to ensure that the loose granulated, can achieve better strength. |
