What is the impact of sand making machine rotor accumulation?

The rotor is the core component of the sand making machine, where the materials are mainly crushed and reshaped. In actual production, it is normal for the rotor to accumulate material. However, the amount of accumulated material should be appropriate. normal production.

What is the influence of accumulated material in the rotor?

The accumulated material in the rotor of the sand making machine can protect the inner wall of the rotor, and more importantly, protect the rotor throwing head from direct wear and impact. Insufficient accumulated material in the rotor of the sand making machine will expose the throwing head.

And the large stone in the material will be cut directly with the insert, resulting in premature wear of the throwing head. Which will cause the throwing head to fall off the chuck grinding plate; Too much will also cause friction with the rotor, affecting the service life of the rotor.

If the accumulation of material inside the rotor is ideal, the wear on the upper and lower wear plates should be uniform. And the rotor throwing head can be fully utilized, thereby reducing production consumption. If not, then you need to look at the following adjustment principles and methods.

Second, the basic principles of accumulative material adjustment

• 1. The accumulated material inside the rotor can protect the wearing parts and not hinder the material from passing through the crusher.
• 2. The accumulated material is not in contact with the side wall and bottom of the feeding barrel to prevent premature wear.
• 3. The material flow in and out of each throwing port is the same, so that the wear degree of the throwing head is similar. Adjustment method of rotor accumulated material

Let’s share the method of rotor accumulation adjustment:

Adjust the rotor If the rotor just leaves the factory without certain adjustments. It is generally difficult to achieve the ideal working condition. Normally, each rotor needs to be adjusted before it is put into use. Rotor adjustment refers to the control of accumulated material inside the rotor. And the internal accumulated material can be controlled by changing the size, position, and shape of the material guide plate.

The main purpose of adjusting the rotor is to ensure that the accumulated material can spread from the guide plate of the rotor to the insert of the ejection head, and keep the worn part in the middle of the ejection head.

The adjustment method when the accumulated material is insufficient.

If the accumulated material is lower than the height of the throwing head. The width of the guide plate should be increased until the accumulated material is close to the height of the throwing head. If the buildup starts to erode the feed barrel. The solution is to move the deflector plate towards the thrower head. This will move the peak of the buildup away from the feeder barrel without reducing the buildup at the thrower head.

Adjustment method when there is too much accumulated material.

If the accumulated material rubs against the feeding barrel, narrow the guide plate until the accumulated material retreats from the throwing head. If the build-up is still eroding the feed barrel, move the guide plate forward. So that the peak of the build-up is moved away from the feed barrel again without reducing the build-up on the throwing head.

The accumulation of material in the rotor plays an important role in the wear of parts. For example, if the throwing head of your equipment wears too fast. Check whether it is the problem of improper accumulation.
