Two 120 mixing plants

Author: admin Release time: January 19, 2018 Number of visits:

Two 120 mixing plant 2. If the ratio is still abnormal after adjustment, the production shall be stopped immediately, and the laboratory shall be informed to carry out sampling test, and the production shall be carried out according to the new mix proportion. Only in this way can the attendance rate and work efficiency of the equipment be ensured, thus bringing higher value benefits for users. After the drill, the employees said that they had learned how to escape and save themselves in the disaster. All the cement in the spiral pipe shall be transported out, and no material shall be left in the pipe. When the cement in the weighing bucket reaches the loading level, the microcomputer sends out the command to close the butterfly valve, read out the total weight of hopper and material, and start the screw conveyor for batching. Main models and parameters of JZM series friction concrete mixer: model jzm350jzm500jzm750 working performance discharge capacity (L) 350500750 feeding capacity (L) 5608001200 productivity (m3 / h) 1318-20 more than 35 mixing drum speed (R / min) 151512. Preventive measures: (1) the cement dosage, water cement ratio and sand ratio of concrete should not be too large; the content of coarse aggregate should be increased to reduce the dry shrinkage; the mud content of sand and gravel should be strictly controlled to avoid the use of excessive silt; the concrete should be vibrated and compacted, and the slab surface should be plastered and pressed again after the initial setting and before the final setting, so as to improve the tensile strength of concrete and reduce the shrinkage.

Two 120 mixing plants

Two 120 mixing plant phenomenon, local loose concrete, less mortar, more gravel, there is a gap between the gravel, the formation of honeycomb holes. Air entraining agent: it can introduce a large number of evenly distributed, stable and closed micro bubbles 5 in the process of mixing concrete. To sum up, the concrete strength produced by small mixer can meet the requirements of pouring floor slab, and Zhengzhou Changcheng Construction Machinery Co., Ltd. is specialized in production Concrete mixing plant equipment More than 30 years, technology, reliable quality, welcome to visit the factory to buy. As long as the grade of fly ash is selected correctly, it also has a positive impact on the quality of concrete. Phenomenon reason 4: Sensor damage; solution: replace the sensor. 2. Check the power supply voltage: the extra voltage is 380 V, and the error is 10%. The control system adopts the smaller batching control instrument in the world, which has stable ingredients, calculation method and effective error control; it has fault diagnosis system, which can guide and help users to remove faults; the storage and transfer of formula are flexible, and any prescription can be called at any time. In the design of mixing station, the construction and production conditions shall be comprehensively considered, and the mixing operation area, material measuring area, material stacking area and transportation vehicle parking area shall be reasonably divided. 4. Strengthen the quality inspection, whether internal inspection or third-party quality inspection, we should take the initiative to find out the problem, and can not have the idea of passing the stage. In addition to antifreeze in winter, the main problem of the admixture channel is to block the pipe by adhesive precipitation. If the pipeline design is unreasonable, the pipeline is easy to become thin and blocked, so it should be cleaned regularly. Another aspect to be noted is that the admixture is better mixed with water for feeding, so that the distribution of admixture in concrete can be even. 4. The electrical control parts of mixer shall be kept clean and sensitive, and the fault shall be repaired in time. The concrete mixing plant is divided into four parts: sand and gravel feeding, powder (cement, fly ash, expansion agent, etc.). Feeding, water and admixture feeding, conveying, mixing and storage. Repair personnel must have the corresponding technical level; B. (3)。 If the hydraulic components have been cleaned and sealed with plastic plugs when leaving the factory, as long as the storage time is not more than two years, it is unnecessary to clean the internal parts of hydraulic components. (4) The use and maintenance of the oil-water separator and oil mist separator, the compressed air output from the air source device and initially purified, generally needs to pass through the pneumatic auxiliary components (such as oil-water separator, pressure regulating valve, oil mist device, etc.) before entering the pneumatic equipment.
