Judging the quality of ready mix concrete plant should be compared comprehensively from different aspects.
First of all, we need to understand the composition of ready mixed concrete mixing plant:
1. Burden supply system: aggregate hopper, aggregate weighing hopper, flat belt conveyor, inclined belt conveyor.
2. Mixing system: The main machine is double horizontal axis forced concrete mixer, reducer, cement weighing bucket, water and additive weighing bucket.
3. Cement supply system: cement bin, screw conveyor, air compressor, screw electronic scale.
4. Automatic water supply system: water tank, water pump and pipeline.
5. Electrical operating system: computer console, electronic control cabinet, operating room.
6. Operation Control System: Microcomputer Automation or Manual Control.
The following is the method of judgment:
1. The operation of the transmission system should be flexible and there should be no abnormal noise;.
2. The installation of matching lines should be reasonable and the installation of equipment should be correct.
3. If the concrete mixer is a self-falling mixing drum, the radial jump of its discharging ring does not exceed the diameter of the inlet and outlet, and the quality of the steel bar of the vibrating screen on the concrete mixer, the reasonable size of the screen mesh and the sieve hole, and the installation accuracy of the screen mesh shall also be checked;.
4. The quality of cement tank is qualified.
5. Belt conveyor, bucket elevator and cantilever shovel should drive smoothly, operate flexibly, brake can be high, there is no abnormal noise, no chain;
6. Safety valve should not leak;.
7. It is also very important to check the metering system, which is sensitive and accurate.
8. Attention should also be paid to reducing the hoisting temperature of the machine. The temperature on the qualified books should be reached 9. The feeding and discharging of the measuring hopper should be smooth, and there should be no accumulation and spills.
