Concrete mixing plant safety operation note

1, mixer after the mixing Drum should be brought to normal speed after the feeding. Feeding should be timely with water, every time that you add the mixture shall not exceed the rated capacity of the Blender tank and should reduce the material viscosity, feeding the order for the gravel-cement-sand or sand-cement-stone.

2, concrete batching plant feed, no head or hand in between the hopper and the frame. Operation, no hands or tools into the mixing tube's chops and discharge.

3, mixer homework, when hopper rises, prohibit any persons stay in the hopper or by; when it comes to inspection or cleaning material in the hopper when, after the hopper should be promoted with a chain or insert a PIN lock.

4, feeding into the mixing Drum should be carried out in operation, add new material in the mixing Drum should be all concrete removed from the rear of the original.

5, assignments, and mechanical functioning, when unusual or bearing high temperature phenomenon, should stop check; when the required inspection, mixing drum of concrete removal shall be clean, and then conduct further tests.

6, join compulsory mixer maximum aggregate particle size must not exceed the agreed value, and should be prevented from blocking. When mixing, adding the mixing Drum material should not exceed a designated feeding capacity.

7, compulsory concrete mixer mixing blade and stir bottom and side wall clearance should be used to check and confirm that the delineation of when clearances when they exceed the scale, should be adjusted. When mixing blades when wear exceeds the scale, should be repaired or replaced.

8, after homework, should thoroughly cleaning your concrete mixer when the operator when you need access to the cylinder, it is necessary to cut off power or remove fuse and lock the switch box, put up "no close" tag, and there should be someone to care.
