Universality Of Application
Granulators can process a wide range of materials, making them suitable for many industries.
Cost-effective
Using Plastic Granulators to recycle plastic materials is often cheaper than producing new plastic materials from scratch. This is because the cost of extracting and processing virgin materials is often higher than the cost of processing recycled materials.
Versatile
Plastic Granulators can process various plastic materials with varying properties, such as melting point and density, making them a versatile tool for the recycling industry.
Efficient
Plastic Granulators can process large amounts of plastic waste in a relatively short amount of time, making them an efficient tool for the recycling industry.
Types of Heavy Duty Granulators
Reverse Wet Granulator
First, the dry powder is immersed in binder liquid. Then these are broken into granules using controlled breakage. These wet granules are crushed after drying them. These granules have better flow than the rest. The erosion level and wetting level are uniform for them. The granules are finer with its tiny spherical shape. Poor water-soluble particles are ground by this technique.
Foam Granulator
Liquid binder is used in this granulating equipment. A foam generator is used to get the foam. Problems with granulating equipment such as improper binder distribution and inconsistent are reduced by this. Drugs will be softer in hits. The spread soak ratio is high for foam. Therefore, they will help to coat the powders more warmly and the binder circulation is more even. The processing time is less for this. Clogging of spray nozzles is removed in this machine. Low-dose tablets are formed easily by this as the granules are distributed in an even manner.
Rapid Mixer Granulator
These are more corrosion-free ones in the granulator for sale. This mixer's sturdy construction and structure will enhance attributes like durability and performance.
Freeze Granulator
Liquid nitrogen freezes the particles faster than anything else does. The particles are sprayed or suspended into the liquid nitrogen. These particles are frozen the very instant they get in touch with liquid nitrogen. The water content or the ice is removed from these. The homogeneity is retained for these new spherical granules. The granules will be cavity-free. The density of the granules is always under control.
Components of Heavy Duty Granulators
Screw
It is the most important part of the plastic granulator, directly related to the application area and productivity of the extruder. It is made of high-stren and corrosion-resistant alloy steel.
Cylinder
It is a metal cylinder generally made of alloy steel with high heat resistance, high compressive strength, strong wear and corrosion resistance, or alloy steel lined composite steel pipe. The cylinder interacts with the screw to realize the pulverizing, softening, melting, plasticizing, suctioning and compacting of the plastic and to transport the rubber material continuously and evenly to the moulding system. In general, the length of the cylinder is 15–30 times its diameter, so that the plastic can be completely heated and completely plasticized.
Funnel
The bottom of the plastic granulator funnel is equipped with a shut-off device to adjust and interrupt the material flow, and the side of the funnel is equipped with a viewing hole and a calibration meter.
Food Industry
In the food industry, granulator is often applied in food processing, it is used to produce granular materials for food products such as beans, grains and so on. The granular food materials are easy to store and convenient for processing, which increases production efficiency.
Pharmaceutical Industry
A granulator is an ideal equipment for the pharmaceutical industry, it can make drugs into granules, which can be pressed into tablets or used as brewing medicines. The granular medicines are simple to dissolve and absorb by your body, in addition, they have high stability.
Chemical Industry
In the chemical industry, the chemical materials are processed into granules by a granulator, therefore, they are more stable, can be stored for a longer time, and are convenient for transportation. Granulator improves the quality of chemical products.
Plastic Industry
In the plastics industry, the granulator is used to recycle plastics, it can process all kinds of waste plastics and make them into plastic granules, to achieve the purpose of plastic recycling.
Metallurgical Industry
Granulator plays a vital role in metallurgical production, it turns metals and minerals into granules, which are convenient for smelting. Why does the metallurgical industry use granulators? The reason is that the granular materials are easier to burn, so the production efficiency and safety are increased.
Working Principle of Heavy Duty Granulators
Dry Cutting
The dry cutting pellet production method means that after the strip material is extruded from the extruder, it is cut into granules of uniform length by the rotating blade immediately, and then the pellet is sent to the cooling and screening device by the fan through the pipeline. This granulation method is suitable for mixing and granulating polyethylene gas materials.
Water Ring Cutting
The production method of water ring pelletizing means that the strips extruded from the extruder are immediately pelletized by the rotating blade and thrown to the high-speed rotating water ring attached to the inner wall of the pelletizing machine, and then the water flow removes the pellets. Take it to the water separator for dehydration, dry it and then send it to the material cooling device for cooling, which is the finished product. This production method is suitable for mixing and granulating polyolefin materials.
Underwater Cutting
The underwater pelletizing production method means that the strips extruded by the extruder are immediately put into water to cool down, and then cut into pellets, and then the pellets are sent to the centrifugal dryer by circulating water for dehydration and drying. This pelletizing method is more suitable for twin-screw extruder mixing and pelletizing raw materials for larger batch production.
Cold Cutting Pellets
Cooling pellets refer to the material that has been mixed and plasticized by the extruder. It is formed into plastic sheet-like materials from the molding die in front of the barrel. It is first dropped into the water tank to cool down and then coiled up. Then it is cut with a special Pelletizer cuts into pellets. This extrusion and pelletizing production method is suitable for mixing and pelletizing raw materials of polyethylene, polypropylene, ABS , and polyethylene terephthalate.
Maintenance Tips For Heavy Duty Granulators
Bearing
Bearing is a vital component in the plastic crusher. There should be frequent lubrication of the bearing. It will enable it to roll easily without any obstruction. If there is no proper maintenance, rust will cause it to become stiff. While it is very important to lubricate the bearing, it is advisable not to apply excessive lubricating substances to avoid damage to the bearing.
Maintenance Of The Edge And Blade
To ensure that the edges are sharp, it is important to regularly sharpen them appropriately. It is a good way to avoid damage to the tools. Moreover, when the edge is blunt it will require more force for the crusher to break large stones. Furthermore, sharpen the blade to avoid it becoming blunt. It is a good way to maintain the blade for effective use. The angle of the blade should be consistent with the originating angle to accomplish a good shearing function.
Check Before Starting-Up
When you get a new granulator, there are two points for you to take care of. First, before starting the granulator, check whether the rotor blades work normally by rotating them manually. Second, check whether there is metal debris in the feed hopper. That's probably all the checking operations before starting, easy but hard to persevere with. After starting, make sure the direction of rotation of the rotor stays the same with the arrow mark on the machine. Keep the machine in idling condition for 2 to 3 minutes and begin to feed if no anomalies happen.
Check Your Blades Regularly
A visual inspection of the sharpness of the blades should be put into practice. This practice should be built into your regular preventive maintenance schedule, including daily check, weekly check and monthly check. If they are dull, you have two choices: replace or re-sharpen. Most suppliers provide either sharpening or replacement programs, or both, and this should be clearly outlined in your manual.
Don't Forget The Screen
If your blades are dull, especially if they've gone unattended for long periods, your screen and screen cradle may have suffered as well. Most of the regrind is produced by impact forces rather than blade load, and the regrind obtained are big and with a certain compact velocity. So take a look at the screen holes—if they are beginning to appear pear-shaped, it's probably time for a replacement, again from your granulator supplier.
Change Of Cutter And Screen
In a situation where the cutter of a plastic crusher needs replacement, the person who will replace the cutter should give proper attention to the clearance between the fixed cutter and the moving cutter. For the screen, check the pull button to know if it is tight or not. If it is not tight, use the screw to tighten it to the button bracket.
Always Empty Your Storage Bin
Your granulator has a bin to collect the regrind after it is ground and falls through the screen. This bin is often— and inaccurately—referred to as a storage bin. You should never, ever store regrind in this bin. Regrind is just held there temporarily so it doesn't spill all over your floor. If the granulate stays too long in this bin, it backs up. And when it backs up, it increases wear in the blades, wear in the screens, and of course, throughput decreases dramatically.
Troubleshooting of Heavy Duty Granulators
Reasons: Unstable power supply voltage or poor contact; insufficient heater heating or a heater does not work, which makes the motor overload due to excessive torque
Treatment methods: Check the main motor circuit connection of the plastic granulator machine; check the temperature display of each section of the heater, and check whether the heater has poor contact or damage.
Causes: The transmission V belt becomes loose, wears and slips; or the safety key becomes loose or disconnected.
Troubleshooting methods: Adjust the centre distance of the V-belt, tighten the belt, or replace it with a new V-belt; check the safety key, analyze the cause of the break, and replace the safety key.
Reasons: The feeding of the hopper is not continuous, or there is a foreign object blocking the feeding port, or a metal hard object falls into the screw groove to block the screw groove, and the material cannot be fed normally.
Solutions: The troubleshooting method for this failure: increase the feed volume to keep the screw feeding continuously; stop the machine to check and remove the foreign matter in the feed port. If it is confirmed that there is a metal foreign body falling into the screw groove, stop the machine immediately to remove the screw and remove the metal foreign body.
Causes: There are impurities in the raw materials, the feed speed is too fast to make the screw extrusion unstable, or the plasticization temperature is not enough.
Treatment method: Clean the raw materials before feeding or replace the filter screen, reduce the feeding amount to make the screw extrude smoothly, or increase the plasticizing temperature. However, the temperature should not be too high to prevent burns to the plastic and affect the quality of production.
Reasons: The feed system failure caused the twin-screw idling.
Solution measures: Check whether the additive system or the main material feeding system is faulty, and clean the blockage of the plastic granulator.
