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 rotor disc.

The rotor disc must be checked once a week. If there are deep scratches (more than 1mm in depth), they should be reground.

The edges of the round hole of the rotor disc shall be checked frequently. It must be kept sharp. If the edges are chamfered, fine particles will easily go into the joint surface, increasing wear. If a new rotor disc is replaced, and the old rotor disc hole has a bevel edge, the service life of the newly installed sealing plate will be significantly shortened.

Timely repair and grind the rotor disc to remove the worn part, which can save a lot of trouble and costs.
