How to Choose Used Granules Making Machine
 

Market Share and Demand
Plastic granulators are used to enable scrap plastic to be reused in the production of plastic. The market share of plastic granulators is $3.4 billion. Current trends in the plastic granulators market include incorporating some additives to help soften or harden the plastic, depending on where it'll be reused, and mixing the granules with virgin material for the overall resin to maintain a certain quality.

 

Rotor
There are four types of rotors depending on what's being processed. Open, closed/solid, staggered, and segmented. The open rotor is suitable for heat-sensitive resins.
The closed rotor has no space between the knife and the shaft. Consequently, it allows cutting through thick feedstocks. The staggered rotor is suitable for cutting through heavy material, while the segmented rotor cuts through heavy material and increases the number of cuts per revolution.

 

Knife Design
The knives are mounted on the stationary bed or directly in the rotor. The spacing between the knives will determine the type of granule. A small knife space will result in softer material, while a bigger space between the knives results in more rigid granules.

 

Maintenance
Proper maintenance is essential for the machine to produce high-quality granules for a long period. Maintenance will also reduce dust on the granules. As granulators are not designed with maintenance in mind, professional maintenance is something that businesses should take into consideration before purchasing.

 

Intended Use
Businesses ought to know the use they will make of the plastic granulator. Some plastic granulators have a capacity of 1000 kg/hr, while others can process 3000 kg/hr. The method of granulation is also essential. Machines can use either extrusion, blow molding, injection molding, or recycling. The product being processed is another consideration, whether it's bottles or sheets.

Frequently Asked Questions
 

Q: What is a granule machine used for?

A: Granule machines are extruders used for recycling-reclaiming waste plastic to produce raw material. Netplasmak manufactures granule extruders to be used for recycling polyethylene, polypropylene and other types of polymers.

Q: What is the process of manufacturing granules?

A: The granules are formed by the following methods: solid bridges, sintering, chemical reaction, crystallization, and deposition of colloidal particles. Granules are formed from the powder particles by wetting and nucleation, coalescence or growth, consolidation, and attrition or breakage.

Q: What is inside a granulator?

A: In a granulator are two types of knives. The cutting knives (rotor blades) and the stationary knives (stator blades). The cutting knives are mounted on a rotor, which is either open (usually has gaps to let the plastic fall through) or solid. This rotor is spun at high speeds by an electric motor. The motor is situated inside the cutting chamber where the stationary knives are mounted.
As the product enters the cutting chamber, the rotating knives cut the plastic into little pieces, until they are small enough to fit through the holes in the screen. The product will continue to mix and be cut until it is small enough to fall through the screen. The screen is situated under the rotating knives and can be changed so that the holes can be of different sizes depending on your required output size.

Q: Which granulator is right for you?

A: There are as many different types of granulator as there are different types of product. Whether you choose 'Scissor Cut', 'V-type Cut' or 'Helical Cut'. Or open rotor or solid rotor. Or the motor speed… Choices, choices, choices…
If you are confused about your application? At Rawmec, we manufacture Granulators and Shredders – and the output of each differs substantially. Therefore, if you're not certain of exactly what your equipment needs are, contact our engineers and they can quickly assess your needs and help you determine if a granulator is right for you.

Q: What is the types of granulators?

A: The mechanism of the granulators can be oscillating or continuous movement. The most used are those with the continuous movement which are used for a powder with a higher flowability. While the oscillating motion are more used for a powder with a lower flowability. Both of them crush the material that is introduced. Once the material has been crushed, it is forced to go through a sieving process. The sieving process refers to the passage of the granules or grains obtained from crushing through a series of meshes whose pores have different sizes. These meshes are known as sieves.
The purpose of the sieving process to which the particles are subjected inside the granulators is to do a kind of filtering by size, so that only the finest and smallest grains can pass through the sieves whose pores are smaller.
Once it has gone through the sieving process, homogenization of the size of the particles is achieved, they can be given the necessary treatment, depending on their purpose.

Q: What is the main motor of plastic granulators (server)?

A: The main engine of the plastic granulator is the extruder, which is composed of an extrusion system. Moreover, there is a transmission system, a heating and cooling system, and a feeding system. Strong development of resources recycles and turns waste into treasure.
Extrusion system: consists of barrel, screw, mold, and filter. It melts plastic materials into pieces, granules, powders, blocks, or other shapes. And then stabilized at temperature and pressure, measured by the screw, and extruded from the mold.
Drive system. It is mainly composed of a motor, reducer, and belt. Its function is to drive the screw and make the screw achieve the parameter uniform torque and rotation speed of granulators. Given numbers (such as temperature, pressure, rate, etc.). Thereby extruding the product we want.
Heating and cooling system. It is mainly composed of a heater outside the barrel. A cooling element is installed inside the screw. In addition, the function of this system is to heat or cool the screw barrel. Moreover, it ensures the extrusion temperature of the product as required by the specification.
Feeding system. It is mainly composed of a hopper and an automatic feeding device. It has the function of supplying the necessary materials for the extrusion system stably and continuously.

Q: what is the uses of the granulators?

A: With unique screw designs and different configurations, it is possible to produce plastic types: PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA, and other plastic for recycling and color mixing granulation. In addition, the reduction gearbox adopts a high torque design, making the machine work stably and without noise.
Moreover, the screw barrel specially hardens, is wear-resistant, has good mixing efficiency and high output. The vacuum exhaust pipe design, or the design of the standard pipe mouth, can release moisture and exhaust gas during the process. The production process makes the discharge material more stable. The plastic particles are more durable and ensure the excellent quality of the product.
Plastic granulators are mainly used to process waste plastic film (industrial packaging film, agricultural film, greenhouse film, beer bags, bags, etc.). Moreover, this is the most widely used and popular plastic recycling processing machine type in the waste plastic recycling industry.
There are two ways to save energy. One is to keep the power part, and the other is to hold in the heating part.
Energy saving in power part: Mostly using an inverter, save energy through residual energy of the motor. For example, the real power of granulators is 50 Hz. In addition, you only need 30 Hz for production. The unspent energy will be wasted. So, the inverter will change the motor output power to achieve an energy-saving effect.
Energy saving in the heating section mainly uses an electromagnetic heating device. Moreover, the energy-saving rate is about 30%-70% compared with the old-fashioned resistor coil.

Q: What is the difference between granulator and grinder?

A: What distinguishes granulators from our other options is that granulating equipment can reduce your material to a much smaller size than grinders or shredders can, leaving end products as small as 0.2 mm or lower. This much smaller size is made possible because of granulators' open rotor design.

Q: What is the difference between extruder and granulator?

A: The waste plastic granulator is mainly used to make plastic granules from waste plastic through electromagnetic heating and other processes, while the extruder is used to make plastic products. , In terms of working principle, the two are the same, both melt and extrude the material through high temperature.

Q: What is rotary granulator?

A: Rotary granulator is a machine which can granulate materials into specific shapes. It is suitable for large scale production of cold, hot granulation and high and low concentration complex fertiliser. What's more, it is one of key facilities to make compound fertiliser.

Q: What is rapid mixer granulator?

A: A rapid mixer granulator is a high-precision tool used for dry grinding and wet granulation of materials/ingredients in the same tub. High-quality quick mixer granulators are needed to avoid segregation of powder, to prepare material for compression or to enhance flowing characteristics.

Q: What is an impeller in a granulator?

A: An impeller is employed in mixing the dry powder and spreading the granulating fluid in high shear granulator normally rotates at different ranging speeds. The chopper forms part of the high shear granulator and is used to break down the wet lump to produce granules.

Q: How does a plastic granulator work?

A: A plastics granulator shears and smashes scrap plastic to make granules for moulding. Heavy knives are bolted to a rotor turn at high speed, close to a fixed anvil. Plastic offcuts from pressed products are loaded into a small granulator beside the press. Larger quantities are brought to a large granulator.
