Sulfurization accelerator DM screw extrusion granulator

Sulfurization accelerator DM screw extrusion granulatorThe production process materials are fed into the double cone feeder through an automatic elevator after being mixed, and the double cone forces the materials evenly into the main machine screw. Under the compression and shearing of the screw and external heating, the materials are mixed and plasticized. The temperature and pressure gradually increase, presenting a viscous flow state, and the particles are extruded and cut at a certain pressure through the machine head, finally obtaining the desired shape.

Product Introduction

(1) Screw:

(2) Barrel: It is a metal cylinder, generally made of alloy steel or composite steel pipes lined with alloy steel with high heat resistance, pressure resistance, durability, wear resistance, and corrosion resistance. The combination of the barrel and screw achieves the crushing, softening, melting, plasticizing, venting, and compaction of plastics, and continuously and uniformly delivers the rubber material to the molding system. The length of the general barrel is 15-30 times its diameter, in order to ensure that the plastic is fully heated and plasticized.

(3) Hopper: The bottom of the hopper is equipped with a cutoff device for adjusting and cutting off the material flow, and the side of the hopper is equipped with a sight hole and a calibration measuring device.

(4) Machine head and mold: The machine head is composed of an alloy steel inner sleeve and a carbon steel outer sleeve. The machine head is equipped with a forming mold, and its function is to convert the rotating plastic melt into parallel linear motion, uniformly and smoothly introduce it into the mold sleeve, and give the plastic the necessary forming pressure. Plastic is plasticized and compacted inside the barrel, and flows through a porous filter plate along a certain channel through the neck of the machine head into the forming mold. The mold core and sleeve are appropriately matched to form a circular gap with a continuously decreasing cross-section, allowing the plastic melt to form a continuous and dense tubular coating layer around the core wire. To ensure a reasonable plastic flow channel inside the machine head and eliminate dead corners where plastic accumulates, diversion sleeves are often installed. To eliminate pressure fluctuations during plastic extrusion, pressure equalization rings are also installed.

(5) The main machine barrel adopts electric heating and water cooling to automatically control the barrel temperature. The screw core can be cooled by water (oil) to control the temperature of the screw. The machine head is equipped with a pressure sensor for testing melting temperature and pressure.

The air-cooled die surface hot cutting, granulation auxiliary machine, and rotating blades are driven by AC motors with variable frequency speed regulation; The dehydration and drying system consists of a centrifugal dehydrator, a drum vibrating screen, and an air blown storage bin.
