How to choose the machine side recycling shredder of the injection molding machine
Release time:2017/12/21 Clicks:1477


The machine side crusher is often used next to the injection molding machine, so that the water outlet material and waste material generated during injection molding are immediately put into the machine for pulverization, and a fan or suction machine can be installed to realize the immediate recycling and reuse of the pulverized material; It can also be used alone for low-yield crushing needs.

Slow silent shredders are commonly used for side crushing, and their advantages are as follows:
1. The noise is very low, between 15-30 dB during idling
2. The feed hopper and the receiving box are made of stainless steel, which does not pollute the raw materials
3. Tooth-nibbling crushing material to make the cutting particles even
4. No screen design, rarely produce powder
5. The crushing chamber and the knife sleeve can be opened, which is very convenient for cleaning
6. The steel plate on the operating surface of the crushing chamber can be easily opened for easy cleaning
7. A recycling system can be installed, and the material after crushing is immediately recovered to avoid being damp again
8. The recycling system is equipped with a dryer base, and the new and old materials enter the injection molding machine at the same time, eliminating the process of mixing new and old materials


Depending on the requirements of the production and workshop environment, the slow shredder and each model can be flexibly equipped with the tower. Install two material proportional valves, can realize the water outlet, raw materials in proportion to recovery, install cyclone dust removal base, can remove the small amount of dust generated during the crushing process, add conveyor belt can realize automatic feeding crushing after the water outlet.

Common problems in the use of slow shredders:
Q: Can a slow mill crush fiber-fed material?
A: Yes, nylon, LCP and other engineering plastics with a general fiber addition of between 5-30% can be crushed. Materials with a higher amount of fiber can also be crushed, but the degree of wear of the tool will be different.


Q: How loud is the slow shredder?
Answer: When the machine is idling, the noise is about 20 decibels, and when the material is crushed, depending on the hardness of the material, the general noise is 40-60 decibels. (The noise of our normal chat is about 80 decibels)

Q: How does the slow mill control the size of the discharge particle size?
A: Because the slow machine does not have a screen, the particle size of the crushed is controlled by the tooth diameter of the tool.

Q: What is the particle size of the slow speed machine of Sanchuang (Gu'an)?
A: Sanchuang's slow-speed grinder has a discharge particle size controlled below 5mm.

Q: I only need to put it on the side of the injection molding machine to crush the water inlet, I don't need to recycle it immediately, can I use it?
A: Yes, this machine can be operated stand-alone or with an immediate recovery system.

Q: If my recycled and new materials are to be added proportionally, can I do this?
A: Yes, we have a way of crushing immediate recovery is to add a two-material proportional valve, which can accurately control the proportion of new material and recycled material.


Q: I am transparent PC material, can I recycle it immediately?

A: Yes. This machine is not suitable for crushing elastomers, soft rubber, silicone with a hardness of less than 65 degrees. This type of material should be crushed with a special elastomer.



Q: What does it mean to recycle immediately?
A: This means that after the water inlet or defective product is crushed into particles by the crusher, the crushed particles will be automatically pumped to the injection molding machine by the fan or suction machine, and the whole process will be completed in about 25 seconds, and the material does not need to be dried again.

Q: I am transparent PC material, can I recycle it immediately?
A: Yes, the recovery requirements of transparent materials are relatively high, especially PCs, and dust must be strictly controlled. One of the advantages of the slow mill is that there is less dust, and the immediate recovery we have with the function of cyclone dust removal can further remove dust.

Q: If I want to change the material frequently and change the color, can I crush it on the side of the machine?
A: This situation should be divided into 2 parts:
1. Shredder part: It is very easy to change colors, because the crushing chamber of the sanchuang brand slow shredder can be opened, and the air gun can be opened when it is blown.
2. Immediate recovery part: If the machine is equipped with an immediate recovery device, then the plastic hose for recycling needs to be equipped with several more for different colors of materials, because the inner wall of the plastic hose is difficult to clean after dyeing.

Q: Is there any occasion when the slow machine side shredder is not suitable?
A: Yes. This machine is not suitable for crushing elastomers, soft rubber, silicone with a hardness of less than 65 degrees. This type of material should be crushed with a special elastomer.
A: Because the slow-speed grinder uses a gear motor, the tool is tooth-nibbling type, and the material is very wear-resistant SKD-11, so the overall cost will be higher than that of ordinary grinders.



Q: Is there a relatively low-cost machine-side shredder?
A: Yes, the medium-speed machine side crusher can also realize the function of crushing on the machine side and immediately recovering, the cost is relatively low, compared with the slow speed pulverizer, the disadvantage is more dust and noise.

Q: What are the advantages of sanchuang brand slow machine side shredder compared to others?
A: Every company has its own advantages in focusing on a certain aspect of product design, and the advantages of Sanchuang are mainly as follows:
1. Sanchuang brand slow crusher production has been 12 years, and the design for humanized details is in place;
2. Sanchuang brand slow shredder adopts original genuine accessories, Taiwan Shengbang, Taiwan Taian, Japan SKD-11 tools
3. The rotation diameter of the three-innovation brand slow crusher hook knife is larger than others, and it can crush larger sized water inlets with smaller power
4. Sanchuang brand slow crusher whole machine warranty 12 months, including wearing parts.
5. Sanchuang brand slow shredder can be heng under five major guarantees.


Q: What are the five guarantees of Sanchuang?
A: All equipment produced by Sanchuang Company can be guaranteed by 5 major guarantees:
1. Within the scope of normal use, the whole machine is warranted for one year, including electrical devices, wearing parts, etc.;
2. Repair and replacement of accessories within the scope of warranty, without the customer bearing any cost;
3. All brand accessories are made of original genuine products, no deception, no lie, integrity management;
4. Sanchuang factory machine, before the acceptance of the equipment, if it is found that there is a quality problem in the machine, resulting in the customer can not be used or can not produce, Sanchuang company unconditionally return or replace the new product
5. The equipment produced by Sanchuang Company, whether it is our or your reasons, as long as the equipment you purchased is not suitable for use and cannot be put into production, Sanchuang Company unconditionally returns or replaces other models.
