6 steps to choose plastic crusher?

Recently, someone ask me some parameters about crusher. At the beginning, I thought he just needed some spare parts of crusher, so I just provided some simple data he needed. But later, he questions me and he says that I provide some wrong data for him. Because the machine can not reach his requirements when he installs the machine according to parameters I gave him. So I ask him more details about crusher such as materials and capacity. And I find the problem. So I write down this article to help people choose the correct crusher including types and modes.

     Crusher is the kind of machine to crush and shred materials. But it can not crush all of materials. It is mainly used for crushing various thermoplastics and rubber such as plastic profile, pipe, silk yarn, film,and waste rubber products. But big material used for testing machine can not be crushed directly. Generally, crushers can be divided into LTPC Series Crusher(Granulator), LTSWP Series Crusher(Granulator) and LTQL Series Super Power Crusher(Granulator). Although these three are crushers, but they have many difference in structure and application.

Similarities

The same working principle

For LTPC Series Crusher(Granulator), LTSWP Series Crusher(Granulator) and LTQL Series Super Power Crusher(Granulator), all of them are driven by motor to do high-speed rotational motion when they are working. The knife rest of crusher is welded on main shaft, and there are blades of rotary knives on knife rest. The quantity of rotary knives will different if the capacity and mode of crusher are different. The fixed knives are installed in the crusher inside. There is gap between rotary knives and fixed knives. The rotary knife and fixed knife will form relative tendency when rotary knives rotate at the high speed. Utilizing the such action between rotary knife and fixed knife, material will be cut and crush. Then the material after being crushed will come out from outlet.

The same type of rotary knife

The rotate speed of crusher is very fast when the crusher is working, so knives will be easy to abrade even damaged. So we must choose high-quality material to make knives. Generally, we choose SKD-11 steel. Because such steel has better performance. It has better tenacity and high temperature resistance. It will not be influenced if the temperature changes suddenly. Its hardness will more than 62HRC after being quenched. So the service life of crusher will be lengthened if you choose the SKD-11 as the material of knives. And the crushing effect will get better too.

Differences

The difference of shape

These three types crushers are easy to identify because their appearances are totally different.

Compared with another two crushers, the size of LTPC Series Crusher(Granulator) is small. Its feature is that the shape of feeding inlet is designed duck mouth. Such design prevents material from spilling when the crusher is working. Picture 1

The feeding inlet of SWP crusher is designed too long. Such design is good for crushing pipes, profile, etc. Picture 2

QL superpower crusher is big. It can crusher all kings of big size material such as mineral water bottles, packing drums, and bumper, etc. Its knives are big too, so it will generate powerful cutting force. So it has the features of high capacity and powerful crushing effect. Picture 3

The differences of knives

The crushing effect will not reach your requirements if you choose crushers just paying attention to types. So the most important parts of crushers are knives.

Different material chooses different knives. The knife of crusher is divided into cross knife and claw knife. The cross knife is mainly used for sheet material, pipe, or film,  etc. And the claw is mainly used to crush some big block and thick material. The structure of cross knives is in a row with small angle. So it has features of uniform force and uniform size when the crusher crushes material. The claw knife will generates more power when it crushes material because of alternate permutation. So it is especially  suitable for thick and big size material. Film is easy to twine on the claw knives, so the cross knives is also suitable for crushing film.

Different crushers are used for different material.

LTPC Series Crusher(Granulator) is more suitable for small products factories because of small size. It is used to recycle unqualified products. It is mainly used to crush small size and thin wall products such as injection basin, bottles or small electric products.

LTSWP Series Crusher(Granulator) is used to crush all kinds of plastic pipes, profiles so on such as plastic door, plastic plate, window frame, trunking, sheet and plastic pipe.

LTQL Series Super Power Crusher(Granulator) has features of high capacity and high efficiency, so it is the best choice for professional recycling factories. LTQL Series Super Power Crusher(Granulator) is mainly used for hollow products, such as beverage bottles, all kinds of daily packing drums, small injection products including basin, flowerpot, tray, etc. But the big size material for testing machine can not feed into crusher directly to crush. If you need to crush big size material for testing machine, you need to use shredder to shred it and then feed it into LTQL Series Super Power Crusher(Granulator)

Differences of parameters

Because there are distinct differences between LTPC Series Crusher(Granulator) and LTQL Series Super Power Crusher(Granulator). So their capacity, size of knife, main motor power are also different. Please refer the following data:
