Maintenance method of sealing plate for shotcrete machine for dry material2

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 is not allowed to have out of limit stress due to excessive clamping, otherwise it will be excessively worn due to friction heating. The heat resistance limit of the sealing plate is 110 ℃, which generally does not exceed 80 ℃ in use.

Each shift shall clean the sealing plate and check the wear situation. If the rubber plate has been worn to the following extent: the steel is flush with the rubber surface or there is air leakage at the feed hopper, the sealing plate must be replaced. At this time, the rotary lining plate will directly contact the steel of sealing plate, so that the sealing plate can not be fully pre-tightened to obtain effective sealing, thus losing its air tightness.
