Interpretations of what is a plastic granulator?

What is the definition of granulating machine, plastic granulator? Granulating machine and plastic granulator is whether the same? And the fact is not completely the same,granulator includes range is very wide, can say plastic granulating machine, belonging to the granulator granulation machine, but not necessarily plastic granulator, becausegranulation machine also includes some chemical granulating machine, and these chemical granulating machine would not necessarily used in plastics industry, many are widely used in the construction industry however, below the main for your interpretation of what is plastic granulator! Comparison of concept of the system are: plastic granulator machine iscomposed of extruder, extrusion system, the transmission system and the heating and cooling system of the three components of the system, the following are interpretations of the three systems.

Heating and cooling of 1 heating and cooling device is a necessary condition for plastic extrusion process could be carried out. (1) now extruder is usually divided into electric heating, resistive and inductive heating, heating tablets on thebody, neck, head of machine parts. The heating device is composed of external heating tube of plastic, so that the temperature, in order to achieve the required temperatureprocess operation. (2) cooling device is to ensure that theplastic in the temperature range of technological requirementsand settings. Specifically for the excess heat generated shearfriction screw removal, in order to avoid high temperaturedecomposition of plastics, scorch or difficult determination.The barrel into the water cooling and air cooling two, most small and medium extruder adopts air cooling is more appropriate, large use more water or two forms combined with cooling; cooling by central water-cooled screw, objective is to increase the solids conveying rate, stable glue volume, at the same time to improve the quality of the products; but in the hopper. Cooling, one is to strengthen the transport of solid material, prevent heats the plastic sticky jam feeding port, twois to ensure that the transmission part of the normal work.

2 extrusion system of extrusion system including a screw,machine head, machine barrel, hopper and mould, plasticextrusion system through plasticizing into homogeneous melt,establish the pressure in this process and, by continuousextrusion head screw. (1): is the main component of screwextrusion machine, it is directly related to the scope of application of plastic extruder and productivity, made of alloy steel with high strength and corrosion. (2) barrel: is a metal cylinder, made of composite steel pipe with heat resistant, high compression strength, abrasion resistance, corrosion resistantalloy steel or lining alloy steel. Machine barrel and screw onplastic, crushing, softening, melting, plasticizing, exhaust and compaction, and to the forming system of continuous uniform delivery of rubber material. General barrel length to itsdiameter of 15 ~ 30 times, in order to make the plastic fullyheated and fully plasticizing principle. (3): hopper hopperbottom is provided with a cut-off device, so as to adjust andcut off the material flow, the hopper side is provided with ahole and calibration of measuring device. (4) die and die: diemade of steel alloy inner sleeve and outer sleeve is arranged incarbon steel, die forming die. The nose is the role of theplastic melt into rotary motion into parallel linear motion,even into the die sleeve, and giving the plastic molding pressure necessary to. Plastic in the machine barrelplasticizing compaction, the porous filter plate along a certainchannel through the head neck into the die mold, mold core die sets with appropriate, forming an annular gap section decreases,the plastic melt tubular continuous density is formed around thecore wire coating. In order to guarantee the reasonable plasticflow, eliminate the accumulated plastic corner, often placedwith split sleeve, to eliminate the pressure fluctuation of plastic extrusion, also have the equalizing ring set. The headis also provided with a device for die correction andadjustment, convenient adjustment and correction mold core and the die sleeve concentricity.

Extruder according to the angle between the direction of the material and the screw head center line, will head into oblique head (angle 120o) and right angle handpiece. The shell is fixed on the frame by bolts, die in the core seat, fixed in the headline port and nut, a core mold core seat in front, mold and coreseat with a hole in the center, used by the core wire; apressing ring in the front end, for balanced pressure; extrusionbag molding parts by die sleeve and die, die sleeve position bybolts through support to regulate, to adjust the die sleeve on the core position, easy to adjust the extruded layer thickness uniformity. The nose is arranged outside the heating device and a temperature measuring device.

3 the transmission system and transmission system is the role ofthe drive screw, screw the supply in the extrusion process of torque and rotational speed, usually by motor, reducer andbearings.

The three plate three system summary is plastic granulator, the main mode of operation is also the work of plastic granulator isthe vital lifeline, understand the above contents will be able to have plastic granulator, we hope to help.
