Lab Twin Screw Extrusion Water Ring Pelletizing Line

This twin screw extrusion water ring pelletizer is appropriate for the mixing processing experiment of engineering plastics, modified plastics, waste plastics and color masterbatch etc., is featured by plasticizing homogeneity, color proofing and filling modification. The water ring granulating line uses adjustable speed motor, pelletizing with an extruding machine at the same and discharging speed synchronistically. The unit is easy to operate, steady performance, and favorable economic benefit. I.Twin screw extruder Output According to the raw material formulation process Screw diameter Φ20 Length diameter ratio 1:40 optional Screw direction Parallel and the same direction Screw speed 0-120rpm Screw Spindle with 40CrNiMoA chromium molybdenum alloy tool steel, screw thread adopts W6Mo5CR4V2 wear-resisting alloy steel,HRC60 hardness, consisted of conveyor block, mixing block, shear block, mixer block, kneading block and countercurrent block, building block series assembly, according to the parallelism of any material combination, to meet the different needs of the extrusion process Barrel 5 sections of cylinder adopt 38 CrMoAl nitriding steel forgings, liner wear-resistant alloy, hardness is HRC60, via nitriding, conditioning and ultra fine grinding process, the surface roughness Ra≤0.4μm, wear-resisting and corrosion resistance Heating zone
