Types of Plastic Pelletizing Equipment
There are several types of plastic pelletizing equipment available, each suited for different applications:
Single-screw pelletizers
Ideal for simple recycling tasks with consistent material types. These are commonly used for basic recycling operations where the plastic feedstock does not vary significantly.
Twin-screw pelletizers
Suitable for more complex recycling processes, offering better mixing and compounding capabilities. They are ideal for handling a mix of different plastic types and additives, providing superior homogenization.
Underwater pelletizers
These are used for high-output applications where the pellets are immediately cooled by water. This method is efficient for large-scale operations and helps in achieving a smooth and glossy pellet surface.
Air-cooled pelletizers
Suitable for materials that do not require water cooling and are sensitive to moisture. They are preferred in applications where water cooling might affect the quality of the pellets, such as in the recycling of hygroscopic plastics.
The main machine of the plastic granulator is an extruder system, which is composed of a transmission system, a heating and cooling system, and an extrusion system.
The Transmission System
The function of the transmission system is to drive the screw. The torque and speed required for the screw supply during the extrusion process are generally composed of a motor, a reducer and a bearing.
Heating And Cooling Device
The necessary conditions to ensure that the pelletizer can perform during plastic extrusion are heating and cooling. The control system of the plastic granulator includes a heating system, a cooling system, and a process parameter measurement system, which are mainly composed of electrical appliances, meters and actuators.The main function of the device is to control and adjust the drag motor of the main and auxiliary machines, output the speed and power in accordance with the process requirements, and make the main and auxiliary machines work in coordination; Detect and adjust the temperature, pressure and flow of the plastic in the extruder ; To achieve the control or automatic control of the entire unit.
The Extrusion System
The extrusion system includes a screw, a barrel, a hopper, a head, and a mold. The plastic is plasticized into a uniform melt through the extrusion system, and a continuous extrusion die is formed under the pressure in the process.
Material characteristics
Whether the material is powder or molten liquid, whether the slurry and audio paste material can be pumped and atomized, whether the material is thermally sensitive, etc., must be considered when selecting.
Requirements for production capacity
If the required production capacity is large, there are many methods that cannot be applied.
The shape of the granules
Rolling, stirring granulation and spray granulation can obtain approximately spherical particles; shot peening, cooling and solidification granulation can obtain completely spherical particles; extrusion granulation can produce cylindrical particles. The possible impact of particles of different shapes on subsequent work should be estimated.
Agglomeration strength
The mechanical strength of the particles obtained by powder agglomeration and shot peening is weak. If high-strength particles are required, pressing methods or sintering and roasting are required to strengthen them, and high-strength binders should be selected for extrusion molding.
Porosity and density of pellets
Porosity and density are closely related to strength. Some extrusion granulation processes can better control porosity and density to meet certain application needs.
Wet and dry methods
Wet granulation requires expensive solvents, and drying after taking the medicine may cause solvent loss. Some materials may be sensitive to solvents and not suitable for wet methods, and some materials may be heavy during drying. Crystals are in different shapes, and wet method cannot be used; dry granulation is easy to produce powder, which is not suitable for handling toxic chemicals and other dangerous materials.
Space limitation
For example, the extrusion method can obtain higher production capacity with a smaller device, while other methods, such as shot peening, require a higher vertical space to install tower equipment.
In the selection, at least two different granulation methods can be initially selected, and then further refined consideration can be made through experiments. Then consider whether the reliability and flexibility of the equipment are easy to manufacture and maintain, and make the final choice under the principle of the minimum total cost under the required output.
How to Choose a Good Plastic Pelletizing Machine
Rotational speed of the screw
This is the most critical factor affecting the productivity of an extruder. The screw rotation speed is not only to improve the extrusion speed and amount of material, but also to make the extruder achieve high output and get good plasticizing effect. In the past, the main way to increase the output of the extruder is to increase the diameter of screw. Although the screw diameter increases, in unit time extrusion material will increase. But the extruder is not a screw conveyor. Screw in addition to extrusion material, but also to the plastic extrusion, stirring, shear, plastic plasticization. Under the premise of constant screw speed, the stirring and shearing effect of the screw with large diameter and large screw groove on the material is not as good as that of the screw with small diameter. Therefore, modern extruders mainly improve productivity by increasing screw speed. Normal extruder screw speed, conventional extruder is 60 to 90 revolutions (per minute, the same below). Now it has been raised to 100~120 rpm. The higher speed extruder goes from 150 to 180 rpm.
The screw structure
Screw structure is the main factor affecting extruder productivity. If there is no reasonable screw structure, to simply improve the screw speed to increase the amount of extrusion, against the objective law, is not successful. High-speed and high-efficiency screw design based on high speed. The plasticizing effect of the screw at low speed will be poor, but the plasticizing effect will gradually improve after the screw speed is increased to achieve the best effect at the design speed. At this time, it has a high production capacity and qualified plasticizing effect.
Reducer
On the premise that the structure is basically the same, the manufacturing cost of the reducer is roughly proportional to its size and weight. Because the shape and weight of the reducer is large, it means that the material consumed during manufacturing is more, and the bearing used is also relatively large, which increases the manufacturing cost. With the same screw diameter extruder, the high-speed and high-efficiency extruder consumes more energy than the conventional extruder. It is necessary to double the motor power and increase the reducer frame size accordingly.
Drive motor
During the normal operation of the extruder, the motor drive system and the heating and cooling system are always working. The energy consumption of the transmission parts such as motor and reducer accounts for 77% of the overall energy consumption. Heating and cooling accounted for 22.8% of the input energy consumption. Meter electrical accounts for 0.8%. The extruder with the same screw diameter is equipped with a larger motor, which seems to cost electricity, but if calculated by output, the high-speed and efficient extruder is more energy saving than the conventional extruder. For example, an ordinary 90 extruder, with a motor of 75 kw and a capacity of 180 kg, consumes 0.42 kwh of electricity per kilogram of material extruded. However, a high-speed and efficient 90 extruder, with a capacity of 600 kg and a motor of 150 kw, consumes only 0.25 kwh of electricity for each kilogram of material extruded, and the power consumption per unit of extruded quantity is only 60% of the former. The energy-saving effect is remarkable.
Electrics
The electric units is the heart to a plastic pelletizing machine,choosing good brand electric elements maximum ensure the quality of the equipment. Through the choice of high quality screw, reducer, motor, can increase the service life of granulator, achieve the purpose of stable production.
