What is the reason for the needles in the material punched by the wood shredder?

The dry and wet of the material is uneven, in view of this situation, the dry and wet materials should be separated, and the frequency of feeding should be reduced when the moisture of the material is too high, and the speed of feeding should be reduced, and the materials in the crushing cavity of the sawdust crusher should be basically fed after they are finished. 2. It is necessary to pay attention to the timely removal of the materials at the discharge port to avoid the failure to crush the materials in the crushing cavity of the machine due to the blockage of the discharge port. In addition, regularly check the tightness of the motor belt, when it is too loose, it will also cause the wood chip crusher to be untimely and cause blockage.

Then you should also pay attention to the blade of the sawdust crusher, if the output is significantly reduced and the crushing is difficult, it is necessary to check the sharpness of the blade, the easy way is to see if there is any material jumping out of the feeding port or continuous non-cutting. 3. The processing of the production line needs to be combined with the cooperation of the trough debarker and the conveyor, the wood logs after peeling, the middle needs to pass through the conveyor belt, and the belt conveyor is used to transport it to the feed port of the sawchip machine, and the pulverizer equipment can be designed as the lower feed port, which is convenient for the processing of the woodchip production line, and the equipment then cuts and crushes the wood after peeling, and the wood chips after forming will fall from the discharge port to another conveyor, and the sawdust machine will transport the materials to the car or the wood chip stacking base. The entire wood chip processing line is circulating without clogging.

If mine is helpful to you, remember to light it up, thank you!

Wood shredders play an important role in the process of wood production and processing. Mainly because the performance of the crusher can greatly affect the product quality; And the operating cost of the crusher is relatively high. Therefore, as an important piece of equipment, once the wood crusher fails, it is very likely to lead to the generation of substandard products and the failure to produce normally.

Therefore, we must actively deal with the possible failure of the wood crusher. The following is an analysis of the common faults of wood crushers.

1. Uneven feeding.

1) Cause of failure: Uniform feeding plays a key role in the efficiency of the crusher. The uneven feeding of the pulverizer can seriously affect the quality of the crushed products of the pulverizer.

If the crusher is overfed, it is easy to cause a sudden increase in the load of the motor, which makes the current fluctuate violently and even burns the motor.

2) Solution: Using scientific feeding method, negative pressure feeding can be used to avoid manual feeding. Advanced feeders and frequency modulators. The material can be evenly fed into the pulverizer.

2. The moisture of the raw material is too high or there is more lint.

1) Cause of failure: When the moisture of the raw material is too high, such as the moisture of corn increases by one percent, the current will increase by about 10 percent, and the source material has more cotton wool, such as more cotton wool of cotton meal, which will seriously block part of the screen of the crusher, and the material can not be discharged from the crushing chamber in time, resulting in great current fluctuations.

2) Solution: Choose raw materials with low moisture. Sifted cotton meal is used.

3. The hammer blade of the wood crusher is worn.

1) Cause of failure: The hammer mill uses many high-speed rotary hammers installed in the crushing chamber to crush the wood and complete the work. When the hammer is worn, the ability of the hammer to hit the material will be seriously reduced, and the material layer in the crushing chamber is easy to thicken, and the discharge is affected, resulting in great current fluctuations.

2) Solution: Install a new hammer or turn around to install the hammer.

4. The feeding direction is inconsistent with the rotation direction of the hammer.

1) Cause of failure: Under the condition of normal operation, the direction of material falling is consistent with the direction of rotation of the hammer. The material can be crushed and quickly passed through the screen; When the direction of the material falling is opposite to the direction of rotation of the hammer, the material will stay in the crushing chamber for a long time, and part of the mechanical energy will be consumed in vain, resulting in violent fluctuations in the current of the wood crusher.

2) Solution: Adjust the material guide plate to make the material fall consistent with the direction of rotation of the hammer.

The motor indicator pointer is biased too wide. When the wood crusher is working, if the feeding speed is too large, the inlet and outlet will be blocked, and the motor indicator needle will be biased very much, which means that the equipment is overloaded, in this case, the motor will be burned out for a long time, and the measures that need to be taken are to reduce the feeding speed, or close the material port, so that the load of the equipment is reduced.

1. Uneven feeding.

2. The moisture of the raw material is too high or there is more lint.

3. The hammer blade of the wood crusher is worn.

Generally, as long as you buy a regular manufacturer! Nothing is faulty! I sharpen it when the blade is not sharp! Nothing else is faulty! Regular maintenance is good!

1. First draw a small circle around the eye of the needle on the fabric, with the eye of the needle as the center, and then sew a small flower here.

2. The needle thread passes through the needle eye in the middle of the small circle from the bottom up, and then threads the edge of the circle from the top down.

It depends on what structure of the grinder, if it is a mill, it must not be granular, but if it is a powerful pulverizer of Lihint, it will be granular, and the wood itself is grainy, and many of them are a little long and granular. In addition, the size of the customized mesh is different, and the particle size and shape also have an impact.
