It is suitable for major industries, such as: plastic industry, electronic manufacturing, electrical appliances, lamps, auto parts, plastic recycling and other industrial applications.
Buying a suitable plastic crusher has a lot to do with the crushing effect of the crusher and the service life of the equipment.
The following selection tips will teach you how to choose the right plastic crusher for you:
1. How to choose the right knife type?
The claw type blades are suitable for the crushing and recycling of various plastics, especially for larger of plastic head material or various types of harder plastics (such as injection lump plastics, shoe last, etc.), and the effect is better. Plastic products such as PVC\PET\ABS\PP\PE\PC\PMMA\PA\PS are recommended to use claw type plastic granulators.
The flake type blades are suitable for crushing general plastics like sheets, tube, profiles, plates and packaging materials, and sprue materials, also runners, etc. PVC\PP\PC\PS and other plastic products are recommended to use flake type plastic granulators.
The flat type blades are suitable for recycling of boxes, thin pipe, blow molded parts, plastic bottles, plastic shells, leftovers from nozzles and various thinner plastic products. Flat plastic crusher is recommended for PE, PET and other plastic products.
The V type blades are suitable for the recycling of various hollow products, leather, films and other plastics.
2. How to choose the right model?
The general crushed material can enter the crushing chamber. If it is a thick or hard defective product or a plastic head material, it is better to use a model with one or two levels of motor in combination with the output.
The size of the crushed defective products or the nozzle should not be larger than the size of the grinding chamber. If it is to crush long trays or pipes, etc., it is recommended to choose a inclined plastic crusher, without cutting, and directly crushing.
The grinding capacity of plastic crushers varies according to different models. If you are a customer who needs a large amount of crushing, on the premise that the product can enter the crusher, you should select the model according to the output of the granulator. The output of ordinary plastic can be found in the specification table. When crushing mineral water bottles, plastic bags and film products, the output is only about 1/3 of the minimum value on the specification table.
Choose different types of crushers according to different application scenarios. For example, for centralized crushing and recycling of materials, standard plastic crushers can be selected according to the output and material characteristics; if they are directly recycled by beside-the-press crushing, you can choose beside-the-press granulators. Online plastic crusher with the extraction type can greatly reduce the labor cost, and the crusher is automatically recovered and reused.

Plastic crusher is mainly applicable for breaking down solid plastic so that the waste plastic can be easily and efficiently recycled without any inconveniences or unwanted hazards. Waste plastic materials include purgings, sprue, gates, reject.
Other than used for secondary size reduction, they’re also utilized to crush and clean material if add a water sprinkler system.
In this article, we show you how to choose plastic crushers.
1. How to Feed
There 3 ways of feed a crusher by hands, by conveyor and by forklift.
The latter 2 options concern machines so they can transport heavy materials in a bulk. Still, take special care of no metal can mix with the infeed materials.
Manual feed is direct and simple. With manual inspection, infeed materials usually can be sorted out metals. However, unlike machines, humans cannot lift heavy objects.
2. What are your materials?
Usually, a crusher cannot process metal-inclusive materials. Pure plastic and wood are ideal materials for plastic crusher. In some rare cases, hard plastics like PA(nylon) are too hard for a standard crusher. This requires a special rotor. Plastic film roll and raffia are not directly process by crusher, because they significantly decrease crusher output.
3. Output Size
Screen opening size determines output size. In general, the output size is around 10-12mm. If you want smaller, go for a plastic pulverized, which can further size reduce to 1-5mm.
For film and hard plastics, Wiscon offers a unique design. For other general plastics, a standard screen is sufficient.
4. How to Collect
Cyclone collection or conveyor? If your end products contain excessive powder, cyclone removes the powder and collect regrind. A metal detector in between crusher and cyclone can remove metals.
A conveyor is rarely used unless a second crushing is required.
Some other points regarding choosing a plastic crusher
Can crusher deal with the biggest lump size of this infeed substance?
Is your machine constructed with high-quality workmanship and materials?
Can the device’s functioning mechanism manage the properties of this substance: i.e. corrosive, hard, soft, abrasive?
Does the crusher need a conveyor?
Does it create excessive powder?
Can it be appropriate for your working conditions and temperature?
Can the device meet the need for the simplicity of maintenance and inside accessibility?
Conveyed, dropped or manually tossed?
Can the crusher fit the link settings?
Run with minimal vibration or noise?
How is the substance be transport and fed?
Are skilled field service and client services available from the provider?
Can the crusher create the output size required?
How to Choose Plastic Crusher Conclusion
In conclusion, plastic crusher model selection involves the ways of feed and collect materials, capacity, material composition and output size. How to choose a plastic crusher is not a challenge. All customers can follow this guideline to select an ideal machine for plastic recycling.
It’s a primary crusher. The jaw crusher is a machine for crushing rocks and other hard and abrasive materials, such as granite, ores or recycled concrete, usually for industrial purposes. The crushing device consists of a fixed plate and a swing plate called jaws between which the rock is trapped and crushed. A motor and a belt transmit the movement to an eccentric shaft that drives the movable jaw by rotation. A spring returns this moving jaw to let the crushed materials gradually descend into the crusher. When the materials are small enough, they fall into the space between the crusher’s two jaws. The crusher breaks the rock into small stones that are used in particular for manufacturing concrete for construction and roads.
Jaw crushers use a rudimentary and reliable technology that does not require much maintenance or engineering knowledge. They are the most popular crushers in the world. Jaw crushers are particularly suitable when the main objective is to reduce large blocks into smaller pieces that can then be processed by other machines.
Advantages:
- Low maintenance and operating costs because it has few moving parts
- Reduces the raw material to about 150 mm
Disadvantages:
- Not suitable for small material requirements (smaller than 150 mm). If a smaller grain size is required it can be used in combination with other crushers.
- Not suitable for handling clay or metal mixed with rock.
Cone crushers, also known as conical crushers, break rock between an eccentric rotating head and a bowl. The rotating head is covered by a wear-resistant mantle. The large pieces are broken once between the two jaws, then they gradually descend into the crusher where they continue to be broken until the pieces are small enough to pass through the narrow opening at the bottom of the breaking space. A cone crusher can crush a variety of rocks, from medium to hard. The way a cone crusher operates is similar to how a gyratory crusher does, but in a cone crusher the slope in the breaking space is not as steep.
Although it is known for its ability to crush hard and abrasive ores and rocks, the cone crusher is better suited for secondary crushing. It is designed to crush pre-dimensioned materials, generally of 100 mm, 150 mm or 200 mm, and provide finished products of small dimensions.
Advantages:
- Sturdy construction
- High productivity
- Easy adjustment
- Low operational costs This type of crusher is equipped with a spring release system that protects it against overloads and allows uncrushable materials to pass through the crushing space without damaging the crusher.
- Inexpensive machine
Disadvantages:
- The cone crusher cannot take material of all sizes. The materials must be pre-dimensioned for the crusher (usually 200 mm or less).
- The finished product is not homogeneous, which is an essential requirement for many material specifications.
- Not suitable for handling clay or metal mixed with rock.
Impact crushers can be used as primary crushers, secondary crushers or tertiary crushers depending on the size and technology. They are equipped with beaters, also called hammers, and impact plates. They operate in the following way: they are fed from the upper part, then the stones are hit by the hammers and projected towards the plates. The stone breaks on the plate and bounces back towards the hammers. The process is repeated until the stone reaches the desired size. Impact crushers are ideal for mixed materials. They can crush clay, dirt or metal mixed with the feed material, for example reinforcing bars, wire mesh or anchors. They can crush hard materials, but are especially suitable for soft to medium rocks. Impact crushers, also called hammer crushers, can have a horizontal shaft or a vertical axis.
Horizontal-shaft: generates a uniform cubic product. It can accept all feed inputs and ensure maximum productivity, both in primary and secondary crushing.
Advantages:
- The impact makes it possible to better control the size of the crushing result, for example better cubic gravel.
Disadvantages:
- Operating costs can be higher.
- It can have difficulty breaking small parts, as the crusher’s ability to break blocks is related to the energy accumulated by the stone upon impact with the hammer. This energy therefore depends on the speed of the hammer, but also on the mass of the stone.
- Wear of the beaters depends on the matter being crushed.
Vertical-axis: can create quality sands. It crushes the gravel even more finely because it breaks the most persistent bonds of the aggregate. This results in a sand with optimal consistency and shape, especially for concrete. This machine combines rotational energy with impact energy for crushing.
Advantages:
- High production capacity
- High breakage rate
- Low energy consumption
- Uniform grain size
Disadvantages:
- Can only be used to obtain fine finished products
While stationary crushers have the advantage of being sturdy, it can be advantageous to choose a mobile crusher to get the crusher closer to where the it is going to be needed. Wheeled crushers can be moved to a construction site using a truck. These units are generally autonomous and therefore do not require an additional diesel engine to operate. Crawler crushers are designed to be moved around constantly. They are more compact and weigh less than mobile wheeled crushers.
Mobile crushers perform the same types of crushing as stationary ones. For reasons of autonomy, they also include a hopper and a conveyor to feed the crusher, as well as a second conveyor to evacuate the final product.
