1, Check the aggregate bin of concrete mixing plant is full or not, powder tank storage is enough and water tank water level, each material source whether to meet the construction needs.

2, Check the gas road, waterway whether there is leakage, leakage phenomenon, whether the hose breakage, aging. The pneumatic, electric butterfly valve action is accurate in place to ensure that the butterfly valve closed well.

3, Check the oil level in the speed reducer, is degenerate, does not match the requirements should be added or replaced; the opening mechanism of each lubricating point, the hopper screw conveyor lubrication points required to add grease.

4, Check whether the conveyor belt deviation, proper tightness is serious, do not meet the requirements must be adjusted. Belt conveyor roller rotation is flexible, otherwise it should be removed cleaning or replacement of internal bearings.

5, Check the fastening bolts are loose, especially the mixing cylinder frame, blade and liner bolts, so as not to loose.

6, Check the water in the three conjoined filter, if the amount of water must be released; oil mist oil volume is sufficient, should be added when insufficient. Each rubber pipe connection is good, can not loose phenomenon.

7, Check the concrete mixing plant's mixing console each department: each lubricating point is lubricating oil pump; oil is finished; the lubrication system is working properly; leaf blade connection is good, and the lining plate gap is too large, should be adjusted to a minimum clearance of 3-5mm; the lining board is damaged or lost, the blade should be 1/2 immediate replacement.
