Maintenance method of sealing plate for shotcrete machine for dry material

The shotcrete machine for dry material is suitable for the most difficult site conditions with less maintenance. However, like all rotor shotcrete machines, regular maintenance must be paid attention to.

The sealing plate and rotor lining plate are the key parts of the machine. Pay attention to their maintenance to ensure that there is no fault during operation. Today, let's learn how to repair and maintain the sealing plate.

The pressing force exerted by the rotor clamping system on the sealing plate is unevenly distributed on the whole plate surface. And it is the largest between the discharge port and the residual air port. And the maximum pressure point constantly drifts back and forth with the rotation of the rotor. This pressure difference can be solved by the pressing system, so that the air leakage on the joint surface is extremely slight when the machine is running.

The correct pressing of the machine in use has an important impact on the wear cost. If the compression is improper, the high-pressure gas will escape from the joint surface between the two plates, and carry out fine particles, which will produce dust near the machine. The explosive action of this fine sand will erode the sealing plate, making it invalid in a short time.
