2.Factors affecting the productivity of concrete mixing plant  are in addition to mixing time and time utilization factors. There are also many related factors, such as the production organization, the management and operation quality of the equipment, among which the technical condition of the equipment operation, the preparation of the raw materials and the transportation vehicle have obvious effect on the guarantee and the improvement of the productivity;

3.To strengthen the maintenance of concrete mixing plant equipment to ensure that equipment in a good state of technology, and in line with national environmental law requirements, the establishment of strict maintenance testing system and preventive measures to achieve timely repair;

4.In order not to cause special reasons for the concrete mixing plant equipment downtime, there should be sufficient capacity of finished material storage;

5.Sampling inspection of raw materials, different specifications of the aggregate (including powder) to be stacked, and do dust and rain. Aggregate storage capacity of more than 5 times the amount of daily consumption,and powder need more than 2 times of daily consumption.
