SJ series two - stage water material automatic feeding type extruding granulator.

SJ series of two stage water automatic feeding PaiQiXing extruding and granulating machine group, mainly by a plastic extruder and a no discharge is plastic extruder series into a cascade of waste plastics recycling granulation equipment.
SJ series of two stage water automatic feeding PaiQiXing extruding and granulating machine group is my company's mature products, commissioning of the vent can effectively eliminate the material melting process of water and volatile gas, uniform particles, strong, beautiful, high production efficiency, plastic granulator, plastic crusher, automatic feeding granulator unit, configuration, its large screen institutions, can greatly improve production efficiency.

SJ series of two stage water automatic feeding PaiQiXing extruding and granulating machine group like airflow granulator and water spray granulator, equipment parts mainly include: plastic granulator, single and double screw plastic extruder, plastic film blowing machine, bag-making machine, printing machine, coating machine, tape machine, tape cutting machine, cutting machine, packaging machine.
The modified formula is mainly made of alloy materials, especially in the current application areas of PET, PC, ABS, (PP, PA).
The plastic formula develops the formula of plastic film, degradable film, plastic film granulator, plastic film crusher, automatic feeding granulator and PET peening and toughening.
The difference is that it has a steady flow of water through the surface, and it has direct contact with the surface.
The size of the cutting chamber is enough to allow the cutter to rotate freely across the surface without limiting the flow temperature.
The molten polymer is extruded from the mouth mold, the rotary knife cuts the granules, and the granules are removed from the cutting room by the tempering water to enter the centrifugal drier.
In the dryer, water is drained back into the tank, cooled and recycled.
The grain is removed by the centrifugal drier.
Strip production line cost is not high, easy to operate, and clean and convenient.
This has its advantages for the mixing of color material, because the replacement of two batches of different color materials must be thoroughly cleaned.
However, the disadvantage of the method is that the cooling section takes up space, and its length is determined by the temperature of the polymer.
Most polymers must be mixed together before they are made into a final product, and then granulated to become a marketable material.
The power required by the granulator is proportional to the amount of extrusion, and it has an exponential relation with the filter size.
There are many different granulator designs, but all SJ series of two - order water materials automatic feeding type extruding granulator can be divided into two types: the cold cutting system and the mold surface hot grain system.
The main difference between the two is the timing of the cutting process.
The cold cutting system, at the end of the processing process from the solidified polymer cut;
However, in the system of the mold surface, when the molten state polymer appears from the mouth mode, the grain is cut, and the granule is cooled downstream.
Each system has its advantages and disadvantages.
Cold cutting system: cold cutting system includes mouth mold, cooling zone (air cooling or water cooling), dry area (if water cooling) and cutting room.
There are two kinds of cold cutting system, which are granulator and bar granulator.
The molten polymer is extruded from the hot die and is cut into granules by rotating blades that rotate on the surface.
This kind of granulation system is characterized by its special design of water - spraying chamber.
Plastic film granulator, plastic film crusher, automatic feeding granulator, the water is spirally wound around the flow, until the granulation chamber.
When the granule is cut off, it is thrown into the water, and the initial quenching is carried out.
The granulated water slurry is further cooled and then fed into the centrifugal dryer to remove the moisture.
The use history of the granulator is almost as old as the granulator.
Including mouth die, cooling section (water bath or blower), drying section (if water cooling) and cutting knife.
With extruder or gear pump extrusion of polymer melt through a horizontal installation the mouth of the mould to form a strip material (the mouth of the modern mold precision machining, uniform heating, stable quality of a material to output).
When the material is discharged from the mouth, it is cooled by a blower or air/vacuum facility or by a water bath.
If the water is cold, the strip should pass through a dry section, with forced ventilation to remove the moisture, and then send the strip to the cutting room.
Using a pair of fixed knife and rotary knife shear function, the strip is precisely cut into the required length.
