1. Improve the conveyor belt hopper. Improving the dropping hopper of conveyor belt is one of the effective measures to prevent the early damage of conveyor belt. The dropping hopper at the transition point of each belt conveyor is improved to increase its ability of passing through foreign matters by 2.5 times. The long and large foreign matters are not easy to be stuck between the funnel wall and the conveyor belt in the conveying process, so as to reduce the probability of foreign matters tearing the conveyor belt.

落料斗处的导料裙板，使其与输送带的间隙沿输送带运行方向越来越大，解决煤块、石块卡在输送带和裙板之间的问题，因此引起的输送带损伤。落差较大的料斗，内部安装缓冲挡板，避免物料直接冲击输送带。

The guide apron at the hopper makes the gap between the conveyor belt and the conveyor belt larger and larger along the running direction of the conveyor belt, so as to solve the problem of coal and stone stuck between the conveyor belt and the apron, and eliminate the conveyor belt damage caused by this. For hopper with large drop, buffer baffle is installed inside to avoid direct impact of material on conveyor belt.

2.在改向滚筒处加刮料装置。在输送带沿线的改向滚筒处加设刮料装置，改向滚筒处物料粘结问题，解决因滚筒粘料引起的输送带局部破损。

2. Add scraping device at the turning drum. The scraping device is added at the turning drum along the conveyor belt to eliminate the problem of material sticking at the drum, and to solve the local damage of the conveyor belt caused by the material sticking on the drum.

3.输送机头、尾及中间转载过渡处的改进。输送机头、尾及中间转载处的过渡长度及过渡方式，对输送带的使用寿命影响很大。须进行合理的过渡设计，应尽量减轻输送带胶面的磨损，确保不出现输送带的折叠、中间凸起现象，落料处不出现物料撒漏。

3. Improvement of head, tail and intermediate transfer transition of conveyor. The transition length and transition mode of conveyor head, tail and intermediate transfer place have great influence on the service life of conveyor belt. Reasonable transition design should be carried out to reduce the wear of rubber surface of conveyor belt as far as possible to ensure that there is no folding of conveyor belt and bulge in the middle, and there is no material leakage at the blanking place.

4.输送机在凹过渡处的压带轮。实践证实，钢绳式输送带横向强度不足，启动时，压带轮造成输送带局部受力过大，导致撕裂输送带，将压带轮全部改为压带滚筒，可彻底解决这一问题。

4. Belt pulley at concave transition of conveyor. This problem can be solved thoroughly when the belt pulley is partially pressed, resulting in excessive pressure on the belt pulley.

5.大机臂架输送带配重减载。煤矿系统堆场堆料机臂架输送带更初使用寿命很短，配重设计过重是造成输送带张力过大，过早龟裂老化的重要原因。在满足输送带运载物料张力的基础上，减轻配重后，运送煤炭由150万t的使用寿命延长到450万t。20万t矿用系统堆取料机臂架输送带原设计配重为25t(含配重滚筒重量)，原装德国进口抗撕裂钢丝带作业不到300万t就严重拉伸报废，经两次减载降低6t配重后，使用国产普通钢丝带，作业量超过800万t。

5. Load reduction of conveyor belt counterweight on crane boom. The initial service life of the conveyor belt of the stacker boom in coal mine system is very short, and the design of counterweight is an important reason for the excessive tension and premature cracking and aging of the conveyor belt. On the basis of meeting the material tension of the conveyor belt and reducing the counterweight, the service life of coal transportation is extended from 1.5 million tons to 4.5 million tons. The original design counterweight of the boom conveyor belt of the 200000 t mining system stacker reclaimer was 25 t (including the weight of the counterweight drum). The original anti tearing steel belt imported from Germany was seriously stretched and scrapped when it was less than 3 million tons. After reducing the counterweight by 6 tons twice, the domestic ordinary steel wire belt was used, and the operation volume was more than 8 million tons.

6.料流方向调整。料流方向对输送带的使用寿命具有重要影响，应使物料流与输送带同方向运行，可大大提高设备使用寿命。

6. Adjust the direction of material flow. The direction of material flow has an important influence on the service life of the conveyor belt. The material flow should run in the same direction with the conveyor belt, which can greatly improve the service life of the equipment.

7.输送带局部损伤修复技术延长使用寿命。(1)局部热硫化；也就是大家常说的输送带热流化需要配备硫化机。(2)局部冷泼，产品有德国迪普特技术液体高分子复合修复材料等，但需常温固化10h左右；(3)局部冷粘，采用德国迪普特公司修补条(纵向裂口)、冷粘胶一T2复合胶纵向填补裂缝堵(需专用胶枪)。这两种方法优点是人力物力投人较少，具有较好的耐磨损和补强性能，恢复时间较短，缺点是对环境的要求高，不能恢复到原输送带表面平整要求；(4)输送带喷涂修复技术。该技术是将几种液体材料经专用设备混合，高压喷到皮带磨损表面，根据需要喷涂一定厚度的耐磨层。固化时间短，适用于连成片的局部磨损，效果很好，缺点是需要专用设备。

7. Local damage repair technology of conveyor belt can prolong its service life. (1) Local hot vulcanization; that is, it is often said that the conveyor belt heat fluidization needs to be equipped with curing press. (2) For local cold pouring, the products include liquid polymer composite repair materials of German duput technology, but they need to be cured at room temperature for about 10 h; (3) for local cold bonding, the repair strip (longitudinal crack) of German duput company and the longitudinal filling of crack plug with cold glue-t2 composite glue (special glue gun is required). The advantages of these two methods are less manpower and material resources, good wear resistance and reinforcement performance, short recovery time, but high environmental requirements and can not be restored to the original conveyor belt surface leveling requirements; (4) conveyor belt spray repair technology. The technology is to mix several liquid materials with special equipment, spray them on the wear surface of belt under high pressure, and spray a certain thickness of wear-resistant layer as required. The curing time is short, and it is suitable for the local wear of continuous sheets, and the effect is very good. The disadvantage is that special equipment is needed.

8.合理选择皮带类型与维护。合理选择类型，根据季节变化及时调整沿线纠偏装置，加防晒罩以及冬季维护等措施亦可延长输送带寿命。

8. Reasonable selection of belt type and maintenance. Reasonable selection of type, timely adjustment of deviation correction device along the line according to seasonal changes, adding sunscreen cover and winter maintenance can also prolong the service life of conveyor belt.

9.其他管理问题。加强托辊及清扫器管理，损坏要及时更换。控制带载启动。

9. Other management issues. Strengthen the management of idlers and sweepers, and replace the damaged ones in time. Control load start.
