Aggregate conveying system-concrete mixing plant

Is to measure the aggregate to the temporary storage of measurement process. Includes accessories such as belt conveyor feeding belt conveyor. Common symptoms: no-load or load in belt conveyor during operation, appears to run or the belt is slipping when the load operation, caused by leakage, abnormal wear of the concrete batch plant equipment, reducing the efficiency of concrete.

Analysis:

Belt by by of forces in belt width direction Shang of Heli not for zero or vertical Yu belt width direction of pulled stress not uniform and caused, led to belt partial run of reasons many, so should in design, and making, and installation debugging, and maintenance, aspects to solution belt partial run; belt in overload or rain day skid, main is active drum and belt Zhijian of friction coefficient small, active drum to belt of torque small, belt on will appeared skid.

Treatment methods:

1, adjust the tensioner method: apply when the belt is running, run around or run in the same direction without a fixed direction, that belt loose or the belt tension on both sides of different, adjust the belt tensioner and make it work properly.

2, adjust the roller method: apply to the belt running in the drive roll, indicating active cylinder installation horizontal or perpendicular to the belt width different, shall adjust the level of active drum and parallelism, and so on.

3, adjust the bracket bracket method: adaptation of the belt always runs to one side at the no-load, the belt should be run near the idler bracket along the belt running direction adjustment 1---2cm, or idler bracket height on the other side 0.5---1cm or running belt rack at the appropriate height.

4, remove adhesion method: apply belt after running for some time, due to sand, stones and other fixtures attached to the surface of the drum, roller of diameter increases, leading to uneven force, yes the belt runs, you should promptly clean up glue.

5, adjust the belt law: If the belt edge wear, or after the adhesive joints are not parallel, Larry balance on both sides of the belt should be repaired or replaced in a timely manner.

6, installation, spherical roller, limit roller method: install groups of self-aligning idler (flat-roll or roll Groove) may automatically correct belt run; increased spacing roller, rack installation at the belt is running, to reset the belt force.

7, increasing friction:

① increasing belt tension body weight and adjusted the tension belt adjusting screw, so as to increase the friction.

② cut straight slots in the active drum layer, increasing the coefficient of friction.

③ around drive pulley tensioner rollers, increasing the angle of the belt on the drive pulley, so as to increase the friction.
