1. The plastic crusher should be placed in a ventilated position to ensure the heat dissipation of the motor during operation and extend its lifespan

2. Lubricating oil should be regularly added to the bearings to ensure lubrication between them

3. Regularly check the screws of the cutting tools. After using the brand new plastic crusher for 1 hour, use tools to tighten the screws of the moving and fixed knives, and strengthen the fixation between the blades and the knife holder

4. To ensure the sharpness of the cutting edge of the tool, it is necessary to regularly inspect the tool to ensure its sharpness and reduce unnecessary damage to other components caused by blunt or missing blade edges

5. When replacing cutting tools, the gap between the moving and fixed blades should be 0.8mm for crushers above 20HP and 0.5mm for crushers below 20HP. The thinner the recycled material, the larger the gap can be adjusted appropriately

6. Before the second start-up, the remaining debris in the machine room should be cleared to reduce start-up resistance. The inertia cover and pulley cover should be opened regularly to remove the ash outlet under the flange, as the powder discharged from the plastic crusher room enters the shaft bearing

7. The machine should be well grounded

8. Regularly check whether the plastic crusher belt is loose and tighten it in a timely manner

Dongguan plastic crushers can be roughly divided into the following three categories:

(1) Hard plastic crusher, suitable for crushing various small and medium-sized plastic sheets:

1. Crushing and recycling of ABS, PE, PP and other sheet materials.

2. A rectangular feeding port uniquely designed for crushing board materials, which facilitates the feeding and crushing of long strip boards and improves work efficiency. Optional suction fans and storage buckets can be used to form a board crushing and recycling system, which can fully utilize the recycling efficiency

3. Using sealed bearings to ensure that the bearings rotate well for a long time; Reasonable blade design, uniform granulation of products; The knife holder has undergone heat shrink treatment, resulting in a beautiful and elegant appearance design.

(2) Powerful plastic crusher:

1. The blade structure is between a claw blade and a flat blade, suitable for crushing plastic products such as ordinary sheets, pipes, profiles, plates, and packaging materials.

2. Universal plastic crusher, using sealed bearings to maintain good bearing rotation for a long time; The blade design is reasonable, using alloy steel blades, and the product is uniformly granulated; The blade holder has undergone heat shrink treatment and strict balance testing, resulting in a beautiful and elegant appearance design.

(3)Plastic pipe plastic crusher:

1. Suitable for crushing and recycling various small and medium-sized plastic pipes, such as PE, PVC pipes, silicon core pipes, etc.

2. The uniquely designed round tube feeding port for crushing pipe materials facilitates the feeding and crushing of long and narrow pipe materials, improving work efficiency. The optional combination of suction fan and storage bucket to form a pipe crushing and recycling system can fully utilize the recycling efficiency.

3. Using sealed bearings to ensure that the bearings rotate well for a long time; Reasonable blade design, uniform granulation of products; The knife holder has undergone heat shrink treatment, resulting in a beautiful and elegant appearance design.

Precautions for using Dongguan plastic crusher

1. Before starting, the transmission wheel should be manually moved one or two turns to check whether the rotating knife runs flexibly and reliably, whether there is any collision in the crushing chamber, whether the rotation direction of the rotor after starting is consistent with the direction indicated by the machine arrow, and whether the lubrication of the power machine and plastic crusher is good before starting. Wait for the crusher to operate normally before crushing the plastic. After starting, it should be kept idling for 2-3 minutes without any abnormal phenomena before feeding.

2. Pay attention to the operation of the plastic crusher at all times during work. Firstly, the feeding should be uniform to prevent blockage of the crushing chamber; Secondly, do not overwork for long periods of time. If vibration, noise, high temperature of bearings and machine body, or spraying of materials are found, the machine should be stopped immediately for inspection and troubleshooting before continuing to work. Prevent overload. Strictly prevent unbreakable objects such as metal and wood from falling into the machine. During operation, it is important to pay attention to the temperature of the bearings, ensure that they maintain good lubrication, and check for any abnormalities in sound and vibration. When abnormal situations are discovered, the vehicle should be stopped to check if it is stuck by objects that are not easily broken, or if the machinery is damaged

3. Check if the particle size of the crushed product meets the requirements. If there are too many particles larger than the specified size, the cause should be identified (such as large gaps between the sieve strips, wide discharge ports, whether there are gaps in the sieve due to material support, etc.), and appropriate measures should be taken to eliminate them

4. Before stopping the operation, the feeding should be stopped and the materials in the machine should be drained before cutting off the power supply of the motor.

5. When the crusher is stopped, it is necessary to check whether the fastening bolts are firm, the degree of wear on the parts that are prone to wear, and whether the worn parts should be replaced or repaired in a timely manner.

6. The safety device of the crusher should be kept in good condition and must not be invalidated for the sake of convenience.

Structure and working principle of crusher

1. Main structure: The crusher is mainly composed of a feeding hopper, a crushing chamber, a knife holder, a screen plate, a discharge hopper, a motor, etc.

2. Working principle: The crushed material is subjected to its own gravity or external force. After entering the crusher through the feeding port, it undergoes high-speed rotation. In this way, the material constantly collides and rubs against the tool holder and between materials, and the material is continuously crushed until it reaches a certain fineness. Finally, it is sieved out of the crusher through the screen plate and becomes the desired product.

3. Crusher: Crusher is an important tool in production and an essential earning assistant for us. Understanding its performance, familiarizing itself with its structure, and mastering its usage methods, selecting different types of crushers for different water outlet materials and crusher structures has practical significance for improving crushing output and efficiency, amplifying output value, energy conservation and consumption reduction. It is the main channel for turning beautiful wishes into possibilities.
