Material problem

Different materials have different properties, and the properties of the produced stone not only affect the selection of mobile crushing equipment, but also its production efficiency. If the hardness of the crushed material is too large or the feed particle size exceeds the limited range of the mobile crusher, it is easy to cause insufficient crushing and blockage; if the amount of crushed material is large and the viscosity is high, it is easy to cause insufficient discharge and blockage; if the normal feeding speed is used to feed special materials, it is also easy to cause blockage. Therefore, when configuring the mobile crusher, it is necessary to select the appropriate main crushing equipment according to the properties of the crushed material.

Feeding too fast

When the mobile crusher is in production, it is required to feed at a uniform speed, which cannot be too fast or too slow. If the feed speed set by the feeder is too fast and exceeds the processing capacity of the crusher, it will not only cause the equipment to be in an overloaded state, increase the wear of the crushing parts, but also easily cause the material to be crushed in time and cause blockage. Feeding too slowly will lead to reduced production efficiency. Therefore, when the mobile crusher is in production, in order to avoid overloading the machine, the feed speed should be adjusted according to the processing capacity of the machine to feed evenly.

Too slow discharge

Under normal circumstances, the feed speed and discharge speed of the mobile crusher should be balanced. Any abnormality in either of them will cause blockage. If the discharge port is improperly adjusted or the size of the discharge port is set unreasonably, a large amount of material will be blocked inside the machine, making the discharge speed too slow, which will cause blockage. Therefore, in production, the size of the discharge port should be adjusted in time according to the actual situation so that the crushed materials can be discharged smoothly. If the crushed materials change, the size of the discharge port should also be adjusted accordingly.

Human problems

Although the crushing station is equipped with an electrical control system and the control is relatively simple, its large-scale integrated design also requires operators to have certain experience in handling problems. Part of the cause of blockage is operator error. For example, when the humidity of the stone increases, the feed speed can be appropriately reduced to reduce the production burden of the crusher. If there is no experience, or for the sake of production efficiency, overfeeding, not operating according to the operating procedures, it may cause blockage, or the operator is unfamiliar with the process or a temporary mistake causes blockage. Therefore, equipment operators should undergo rigorous training and be qualified before they can take up their posts. They should not only be familiar with the operating specifications of the equipment, but also understand the process of the entire production line.

Motor failure

When the motor fails, its crushing parts cannot play a crushing role, and the material is not crushed, which will cause the discharge port to be blocked. At this time, the motor needs to be replaced.

Unstable or too low voltage

The motor of the mobile crusher requires a certain voltage to work properly. When the voltage received by the motor of the mobile crusher is unstable or too low, although the motor can rotate, the power it generates is not enough to crush the material in the crushing chamber, causing the material to be blocked in the crushing chamber, causing blockage and affecting production, so it is necessary to ensure the appropriate voltage supply.
