Do you know the operation procedure of concrete mixing plant?

Equipment operation is a link that can not be ignored in enterprise production, and the concrete mixing plant should also be operated in strict accordance with the specifications

In order to prevent the mixer from starting with load, set the traveling operation valve to the zero position. When the mixer is running, loosen the parking brake operating valve, and the air pressure in the air reservoir reaches more than 0.45MPa before walking, and lift the mixing device about 400 ~ 500mm from the ground. When the mixer is driving on the road, observe the traffic rules and drive carefully. It is forbidden to slide in neutral downhill. The mixing plant shall be installed on a firm pedestal. The console of the mixer shall enable the operator to see the working conditions of each department.

The console of the electric mixer shall be padded with rubber plate or dry wood plate. When the hopper is placed in the low position, a layer of cushion wood shall be added between the hopper and the ground. There is no foreign matter stuck in the mixing drum and the transmission and moving parts of each supporting mechanism, warehouse door, bucket door and track; The oil level height of each lubricating oil tank shall meet the requirements; Open the valve to discharge the excessive ponding in the gas water separator in the gas circuit system, and open the blowdown plug of the air reservoir to discharge the oil-water mixture; The steel wire rope and drum winding of the lifting bucket or dragline are correct, the steel wire rope and pulley meet the regulations, and the brake of the lifting hopper and dragline is flexible and effective; During operation, no personnel are allowed to enter in the material storage area and under the lifting bucket. Cover the mixing drum before starting.

During mechanical operation, it is strictly prohibited to stretch your hands and feet into the hopper or mixing drum. When the pulling shovel is stuck by obstacles, it is not allowed to lift by force, lift heavy objects with the pulling shovel, and rotate during the pulling process. The mixer shall not be shut down when it is fully loaded. In case of failure or power failure, the power supply shall be cut off immediately, the switch box shall be locked, the concrete in the mixing drum shall be removed, and then the failure shall be eliminated or the power supply shall be restored. When the rotor cuts the soil, determine the cutting tools according to the soil conditions on site, and ensure that the load borne by the power transmission device is smooth, stable and uniform. In the working state, the rotor is put down through the lifting oil cylinder, the cover is supported on the ground, and no other personnel are allowed to enter within the working range. The power start switch, combination switch, instrument lamp, float switch, pressure reset switch, etc. shall be operated according to the regulations. Observe the indicator lights of each instrument during operation. After operation, the mixer shall be parked on the site, the mixing device shall be placed flat on the ground, all operating levers shall be placed in the middle, and the brake shall be locked.

The above is the basic operation process of concrete mixing plant we summarized for you. I hope it can help you.
