Safety precautions for operation of concrete mixing plant

Precautions for operation safety of concrete mixing plant in order to solve the problem of concrete pollution in Chengdu, Great Wall Heavy Industry Co., Ltd. launched a concrete mixer. The equipment adheres to the green concrete treatment process and adopts low-carbon production mode throughout the process. It can mix concrete into recycled aggregate, successfully transform concrete pollution into renewable resources, and successfully solve urban mixing The equipment can mix concrete into aggregates with different particle sizes. According to the different particle sizes of aggregates, it can be used in the manufacture of recycled brick, recycled concrete and filling materials, and can be recycled in the process of the great wall of urban economy. 3. Because the working mode of the vertical impact mixer is the impact mixing between the materials, the product particle size grade does not change due to the wear and tear of the machine parts, and the mixing efficiency remains constant. Since they were successfully developed and put into the market, they have been welcomed by investors, especially those who have opened sand factories and run stone factories, which have brought a lot of profit space to the sand and stone investors. The effective use of concrete involves not only technical problems, but also social, economic and environmental problems, and needs the extensive participation of the whole society. The materials with particle size less than 5-10 mm, 2-5 mm, and 2 mm are sent to the mixer according to the proportion, and then mixed with certain proportion of cement, fly ash and other additives. The materials are evenly mixed and sent to the hydraulic block machine for molding, which can be naturally cured for 28 days. Sand and stone industry how to take a new road to industrialization has been placed in front of the industry. With the emergence of high-rise, super high-rise and long-span structural engineering, higher requirements are put forward for great wall concrete and high-performance concrete.

Rhombic impact block is used for safety precautions of concrete mixing station to avoid damage to vertical plate after impact and wear of materials. After understanding the working principle of hammer mixer, we will come to know how to better use hammer mixer. In practical application, we will encounter some problems that are not easy to solve. The following are tips for solving common faults of our company's technical personnel based on years of experience, which will help the actual operators. In the scorching sun, workers are always under the impression of "rolling dust". (1) hydraulic washing screen. The higher the area of the sieve, the larger the area of the sieve. Therefore, the radial clearance will increase the vibration of the bearing in the passband. When the rod rotates and rises along the lining plate, coarse particles are sandwiched between them, like a bar screen, allowing the fine particles to pass through the cracks of the rod, which is also conducive to crushing the coarse particles and concentrating the coarse particles at the place where the grinding medium strikes. According to the statistics of the National Bureau of statistics, the growth of raw ore in the first 11 months was 180 million tons, an increase of 22.9%.

Precautions for operation safety of concrete mixing station Zhengzhou Changcheng HX fine sand reclaimer is on site of Hunan manufactured sand production line. The content of fine sand in the waste water discharged by spiral sand washer or wheel bucket sand washer is about 15%, that is, about 15 tons per hour. The waste water is no longer waste water after fine sand recovery machine. The fine sand is recycled, and the water containing a small amount of impurities enters the sedimentation tank. After a short time, the water is clear again and can be recycled. The main components of mixer, mixer, concrete mixer, mixer, mixer, etc. Use. The frequency of vibration exciter can be more than 2.5 by changing the frequency of vibration exciter. Mm decreased from 14% to 1.1%, and the yield reached 1.38 T / h. As a huge renewable resource, urban concrete can not only solve the problem of resource shortage, but also reduce the waste discharge if it can be recycled. The maintenance of large-scale mining equipment is very simple, easy to operate and low oil consumption. However, the working environment of large-scale mining equipment is very bad. The dust and solid particles in the environment are relatively large. The lubricating oil in the equipment is easy to be polluted by these impurities. Therefore, the lubricating oil must have good rust resistance and corrosion resistance. Only in this way, when the lubricating oil is exposed to the outside world The bad environment will not affect the performance greatly. The linear vibrating screen of Changcheng mining machinery adopts two vibration motors as the excitation source. When the two vibrating motors rotate in the opposite direction synchronously, the exciting force generated by the eccentric block offsets each other in the direction parallel to the motor axis, and overlaps as a resultant force in the direction perpendicular to the motor axis, so the motion track of the screen machine is a straight line. Changcheng mining machinery professional for China's highway, high-speed railway and other major projects to improve the stone production line, gravel production line and other complete sets of equipment, our company adhere to the customer demand-oriented, technology innovation as the development power concept, constantly in the market inspection, all to meet customer demand as the goal, strive to create more suitable production line equipment for users.
