The most correct use method of rubber conveyor belt for coal mine

煤矿用橡胶输送带打滑会造成严重的磨损，其是在一定的条件下发生的，当环形输送带的工作阻力达到摩擦力的极限值时，皮带就会在与设备的接触面打滑，从而使得橡胶带无法进行正常的运作，还会对带体造成较为严重的磨损，过程中大量的热量将会产生，从而使得输送皮带在磨损与热量的双重作用下不断损坏，直断裂;

The slipping of rubber conveyor belt for coal mine will cause serious wear, which occurs under certain conditions. When the working resistance of annular conveyor belt reaches the limit value of friction, the belt will slip on the contact surface with the equipment, so that the rubber belt cannot operate normally, and it will also cause serious wear to the belt body, and a large amount of heat will be generated in the process, Thus, the conveyor belt is continuously damaged under the dual action of wear and heat until it is broken;

为了保证皮带输送机设备能够正常的工作，因此矿用输送带必须要满足以下几个条件：

In order to ensure the normal operation of belt conveyor equipment, mining conveyor belt must meet the following conditions:

1、作用在输送皮带上的张力应使得传动滚筒上的圆周力通过摩擦传递到带体上，而橡胶输送带与滚筒之间必须保证不打滑;

1. The tension acting on the conveyor belt shall make the circumferential force on the transmission drum transmitted to the belt body through friction, and there must be no slip between the rubber conveyor belt and the drum;

2、作用在皮带上的张力应足够大，使得矿山输送带在两组托辊间的垂度小于一定值;

2. The tension acting on the belt should be large enough to make the sag of the mine conveyor belt between the two groups of idlers less than a certain value;

3、在长期使用下造成的疲劳损坏是因为橡胶传送带在不断的工作过程中造成的损坏累计，由于煤矿运输带自身的工作性质，带体运行时间一般较长，且其中间断时间较短，因此在煤矿生产过程中，工业输送皮带的疲劳损坏状况相比其他环境下要大很多，由于煤渣、粉尘等的进入，橡胶运输带与机械设备表面的摩擦力不断增加，致使带体自身材料脱落，造成材料的脱落积累，另外由于皮带传输过程中应力的不断变化，致使其材料内部强度逐渐降低，损坏持续积累，更终造成了疲劳损坏的状态;

3. Due to the long-term fatigue of the conveyor belt in the coal mine, it takes a long time for the conveyor belt to be damaged due to the continuous fatigue of the conveyor belt in the process of coal mine production, The friction between the rubber conveyor belt and the surface of mechanical equipment is increasing, resulting in the material falling off of the belt itself and the accumulation of material falling off. In addition, due to the continuous change of stress in the process of belt transmission, the internal strength of the material is gradually reduced and the damage continues to accumulate, resulting in fatigue damage;

4、山东输送带等自身质量受橡胶覆面、尼龙带的衬垫层数、初张力、橡胶带热硫化以及输送带接头的质量等多方面的影响。想要了解更多输送带内容，可以关注我们官网http://www.huafengxiangsu.com

The quality of Shandong conveyor belt is affected by many aspects, such as the rubber coverage, the number of liner layers of nylon belt, the initial tension, the thermal vulcanization of rubber belt and the quality of conveyor belt joints.
