Today, as we introduce strong belt cracking causes and consequences.

   First, should the tape material analysis using known good quality tape conveyor for cement packaging products reach 5a above, but the tape surface wear thin, revealing serious sail line, tape narrowing, even prolong direction of the middle broken in half. While the production of rubber tape for cement packaging products transporting up to 4-5a, but only exposed surface wear and sail line, and does not appear among broken in half. Hardware scratches, cracking cement enterprises conveyor belt center is usually accompanied by the reason of hardware, iron enter. Belt conveyor idler roller does not rotate insufficiency, roller starvation does not turn, causing the tape appeared with roller sliding friction, so that the tape in contact with the local roller, the roller is worn out skin, exposing the metal thorns will tear tape center opened. But there are also belt conveyor wet material, adhesion lower roller, in the center to form the roller cam, raised adhesive tape material only to the center of the contact friction, wear a long time will make the middle of the rubber surface, exposing the inner sail line, then gradually inward gradually wear, so tape the middle of cracking. Tape speed is too fast, fast tape speed tape center is one important reason for cracking. Belt conveyor belt speed is generally 0.8,1.0,1.25 m / s three. Belt conveyor idlers change shape, belt conveyor trough idlers reshaping tape center is one important reason for cracking. U-shaped tape at the center of the upper roller is flat in shape, bending does not occur, no shear stress; V-shaped structure of the center is basically turning point edge into a straight line, tape lines the inner sail by shear force than large, with the running time, the formation of the intermediate cracking.

If you understand the reason for it may be broken conveyor belt to take appropriate measures to prevent them. We can use high-quality conveyor belt, using U-shaped roller, lower tape speed, using the horizontal layout, strengthen the belt conveyor equipment maintenance that several aspects of prevention.

  1, the conveyor intermediate crack use cycles, with a conveyor belt of raw material, and its specifications for B800 * 42.5m, plus a horizontal belt conveyor arranged shaped tilt angle of inclination of 5 degrees, with a speed of 1.45m / s, transportation capacity of 60t / h.

2, material leakage serious impact on the environment, with a plus tape tape mend after cracking method can be maintained temporarily used, but there will still be used to transport raw material leakage, resulting in fugitive emissions, pollute the environment.

3, the drain material impact on the lubrication of conveyor idlers, conveyor cracking due, raw material leakage occurs dust, so that the upper and lower intermediate roller lubrication into dust, oil is dust pollution, the roller poor lubrication.
