The travel speed of the conveyor belt of the concrete mixing plant is generally less than or equal to 2.5m / s. Large blocks, large-abrasion materials and fixed unloading devices should be driven at the lowest speed possible. The relationship between the diameter of the driving roller of the roller conveyor and the number of layers of the conveyor belt, the coordination of the driving roller and the redirecting roller, and the groove angle requirements of the supporting roller should be selected reasonably according to the use. Conveyor design rules.

Prevent the conveyor belt from being blocked by racks, uprights or bulk materials, and prevent tearing. When the conveyor belt is partially damaged, use artificial cotton for timely repairs to avoid swelling. The paper feeding direction should follow the running direction of the conveyor belt. In order to reduce the impact of the material on the conveyor belt, a chute should be used to reduce the falling distance of the material. The receiving part of the conveyor belt should shorten the gap between the idler rollers and use buffer idler rollers as leakage. In terms of materials, the mixing plant meets the requirement of using soft and moderate baffles to prevent the baffles from being too hard and scratching the belt surface of the conveyor belt. When using the conveyor, if there is a lack of support rollers, they should be added and repaired in time; the support rollers are covered by the material, causing the rotation to be ineffective, thereby preventing leakage from getting stuck between the roller and the tape. Pay attention to the lubrication of the moving parts of the conveyor belt, not the conveyor belt contaminated with oil.

Prevent the conveyor belt from starting under load. The deviation of the conveyor belt should be corrected in time. It should be understood that the unevenness of the belt body during the weaving process can cause the belt to loosen and flex when it is tightened. If the thickness of the two sides of the belt body is different, that is, one side is thicker and the other side is thinner, the conveyor belt will be lost. The tension in the production process of the flame retardant tape is different, and the mixing plant will also have deviations. So pay attention to these issues.

The price and quality of the concrete mixing plant are closely related. Only when the concrete mixing plant produces high-quality concrete can it gain more customer support. Therefore, the quality of the ladder-type concrete mixer must be ensured in the production process of the mixing plant. In addition, we must pay attention to some matters in work to ensure its quality. Production and product quality.

1. In the production process, please have someone check the quality of the materials. If you find that the mixing ratio is abnormal, you should check the feed inlet, conveyor belt and operating table to see if they are working properly. If there is a problem, it should be adjusted in time;

2. After the adjustment, if the ratio is still not normal, the production should be stopped immediately, and the laboratory should be notified to conduct a sampling test, and the production should be carried out according to the new mixing ratio;

3. When loading, the loader should cooperate with each other to balance the loading, and must not overflow or be damaged, and ensure the driving safety while driving;

4. During the production process, the operator must concentrate on taking decisive measures when abnormal problems are found, and report to the on-site engineer in time;

5. The mixing time of concrete should be strictly in accordance with the process requirements and the instructions of the mixer, and the mixing time of high-strength concrete should be extended;

6. Appropriate technical personnel and necessary inspection and experiment equipment must be equipped to establish and improve the necessary technical management and quality control system.
