(1) the recycling and reproduction of the waste materials and waste materials of polyvinyl chloride, polypropylene, low-density polyethylene, high-density polyethylene, linear low-density polyethylene and other soft plastic films, bags, silk, tape, sheets and pipes. Take ultra-thin film recycling production as an example. Due to the previous plastic film recycling being extruded by the screw, and the processing temperature of the screw extrusion is too high (180℃-200℃) to make the plastic completely melt, the plastic performance is mostly destroyed; If reproduced, the quality of the produced crystal will be greatly affected. After the pellet machine processing, the tensile strength, viscosity and other damaged, and color does not change. The reason is that the machine processing temperature is only 80℃ to 100℃, so the plastic molecular structure is basically not affected. In the process of production, the machine consumes less power, has high production efficiency and easy to operate.

(2) the recycling and reproduction of the comminution and granulation of the degradable plastic film bag material. Because there are many additives in degradable plastics, it is difficult to recycle the material of degradable plastic film bag. The traditional screw extrusion processing temperature is too high to carbonize the starch in the additive, but also to destroy the plastic properties; Only a small proportion of the powder crushed by an ordinary crusher can be used. So has been to reproduction is not ideal, but also cause one of the reasons for the high cost. Now the granulator has solved this problem very well. Because the machine processing temperature is low, does not destroy the molecular structure of plastics and additives; And because the machine is grinding and mixing, the additive can still be evenly distributed, and the mixing effect is better than the ordinary mixer (rotating speed is 640 RPM).

(3) the waste silk treatment of chemical fiber waste (polyester, acrylic, polypropylene) by crushing, granulating and putting into reproduction.

(4) It can replace kneading machine. This granulator kneading effect millet is very good, and will not make the powder caking, at the same time the discharge of the material has caused particles, do not need to granulate.

The main characteristics of the agglomerator:
A. Crushing, mixing and coloring can be carried out at A time;
B. The machine occupies a small area;
C. Simple mechanical structure and convenient operation;
D, blade clearance adjustable, convenient tool change;
E. High production efficiency and low energy consumption;
F. Basically do not damage the molecular structure of raw materials and physical properties;

Second, the working principle of agglomerator:
(1) Simplified body and upper and lower opening and closing mechanism:
The simplified body of the granulator is divided into upper and lower parts, and the middle part is fixed with 4 bolts (the simplified body can be rotated 360 degrees). The fixed knife of the granulator is fixed on the six towers of the shell, the inner simplified body is made of stainless steel stamping, and the infrared stainless steel heater and thermocouple temperature measuring device are installed between the outer simplified body and the inner simplified body.
The simplified body of the pellet machine is also composed of an inner shell. The inner cylinder is made of stainless steel plate and is fixed on the outer shell by water drenching cooling. Because the inner cylinder of the lower body is in contact with the waste material, the inner denier is made of stainless steel material, which improves the wear resistance and corrosion resistance of the granulator and increases the service life of the equipment.

(2) moving knife, fixed knife and distance adjustment mechanism:
The pellet machine design knife 2, made of T8A, according to the shape of the rotating knife rest, the knife rest according to the main axis of the simplified body center.

The agglomerator fixed 6 knives, according to the fixed knife rest (blade material is the same as above). The fixed tool rest adopts 4 ML0 studs, which are fixed on the shell tower of the lower simplified body and evenly distributed on the same horizontal section of the outer circle of the cylinder. The horizontal circular blade of the moving knife intersects, and the clearance of the moving knife and the fixed knife should ensure the clearance of more than 1 mm according to the installation. The waste is cut off and crushed when the moving knife and the fixed knife turn blade intersects. The fixed tool rest is mounted on the simplified shell, and the tool distance can be rotated and adjusted as long as 4 nuts are loosened. According to the crushing process determined by the crystal seed and material of the waste material to rotate and adjust the clearance of moving knife and fixed knife (calibrated with a feeler).
The moving knife and the fixed knife are fixed on the tool rest with M12 and three hexagonal inner screws. When the blade is blunt, the simple bolt can be rotated to remove the blade easily, and then used again according to the installation after grinding (note: it is necessary to recalibrate the gap between moving and fixed knife).

(3) transmission mechanism
The pelletizing machine adopts electric triangle belt drive, and a pulley is installed on the shaft end of the motor. A triangular pulley is also installed at the lower end of the machine spindle. Connect with 4 triangle belts. The main shaft and the motor are installed vertically, the main shaft is installed in the bearing seat, the upper end extends into the center of the simplified body, the lower cylinder is fixed on the bearing seat, the bearing seat is fixed on the frame, the structure is stable and compact, the motor adopts four I 450rpm/split vertical connection in the court, the belt can be adjusted before and after the loose.

Three, no load test
When the granulator is installed, the no-load test can be carried out. Please check the following steps:
1. Check whether the fixing bolts of the pellet power knife and fixed knife are firm;
2, check and adjust the distance between the blade edge of the pellet in more than 1 mm, can also be determined according to the process requirements of the processing material adjusting the knife distance (calibrated with a feeler);
3. Remove the side plate of the base when adjusting the knife, pull the belt by hand, make the spindle rotate, let the knife pass through 6 fixed knives, each intersection of a knife is measured with a feeler, 6 fixed knives in the same gap, the fixed tool holder is fixed;
4, the use of the point stop mode, check whether the motor steering is in line with the provisions, if the direction of rotation does not match, adjust the motor wiring and then use the same method to try the direction of rotation;
5, start the no-load operation for an hour, in the operation of the machine check whether the operation is stable, there should be no impact and obvious vibration, after an hour of driving, stop to check the fixing bolts and nuts should be no loose phenomenon;
6. Whether the running direction of the oil pump motor in the test water supply device is consistent with the mark.

Four, operation instructions
(1) Preparatory work before operation:
1. Check whether there are sundries and miscellaneous materials in the barrel of the granulator;
2, preheating and heating, according to the process requirements of processing raw materials, determine the preheating temperature, temperature control instrument to control the fixed temperature;
3, water tank filling standby port;
4. The processed raw materials are overweighed and quantified.

(2) Operation:
1. Open the simplified upper cover of the granulator, press the button of the main motor to start the motor, and then put the loose waste wire group into it one by one, but pay attention to the ammeter can not exceed 60 amperes. (150 L 60 amps, 300 L 80 amps);
2. With the increase of time, high-speed rotary cutting, friction, etc., the temperature in the barrel of the granulator increases with the effect of shear heat, so that the crushing material into a semi-plasticized state C semi-plasticized state refers to the cylinder visible forming particles spin, stirring time is long, the particle forming is large, and vice versa;
3. After cooling water is added, the crushed material is quickly cooled and crushed in the simplified body of the granulator. After adding water, stir for 10-20 seconds (high pressure and other absorbent film for half a minute);
4, pull off the tension spring, open the granulator discharge valve, so that the material discharged, into the container, according to the required granule specifications for screening, after screening the powder granulation;
5, and then tighten the material valve, do the second operation from this cycle, under normal circumstances, every 4-7 minutes can complete a cycle, its work efficiency is very high.

(3) Requirements for processed materials:
1. Varieties must be distinguished;
2. Waste must be clean and free from other sundries.
