煤矿用阻燃抗静电pvc输送带、PVG整芯输送带采用整体带芯作为骨架材料，经浸渍，上下覆盖胶具有极女子的抗静电、阻燃等性能的PVG(橡胶面)或PVG(塑胶面)材料而成。
Flame retardant and antistatic PVC conveyor belt and PVG whole core conveyor belt for coal mine are made of PVG (rubber surface) or PVG (plastic surface) material with excellent antistatic and flame retardant properties by impregnating and covering with rubber.
煤矿用输送带用途：产品具用不脱层、难燃烧、导静电、抗纵向撕裂、抗冲击力、抗水侵蚀等优良性能，适用于煤矿、井下及其它易燃场合，输送煤炭、化工类等物品。PVC整芯输送带用于倾角16°以下的干燥条件的工作环境，PVG整芯输送带可用于潮湿的工作境。
Application of conveyor belt for coal mine: the product has excellent properties such as non delamination, difficult to burn, static electricity conduction, anti longitudinal tearing, anti impact, anti water erosion, etc. it is suitable for coal mine, underground and other flammable occasions to transport coal, chemical and other goods. PVC whole core conveyor belt can be used in dry working environment with inclination angle less than 16 ° and PVG whole core conveyor belt can be used in wet working environment.
PVC输送带有什么作用，有哪些装置？PVC输送带在矿石运输过程中，与其他作业相衔接，为保证相关的作业正常运转，常在有的PVC输送带上安装附设装置，为整个生产过程的计量、安全服务。
What are the functions and devices of PVC conveying? In the process of ore transportation, PVC conveyor belt is connected with other operations. In order to ensure the normal operation of related operations, some PVC conveyor belts are often installed with attached devices to serve the measurement and safety of the whole production process.
1、皮带秤
1. Belt scale
为加强矿山生产过程中的计划管理工作，一般都要对每日进人的原矿量和产出的精矿量进行计量。这项工作除了一些小型厂矿采用人工计量的方法来完成外，大部分厂矿都采用在带式输送机上安装皮带秤、电子皮带秤或核子秤来完成。
In order to strengthen the planning management in the process of mine production, it is generally necessary to measure the daily raw ore intake and concentrate output. In addition to some small factories and mines using manual measurement method to complete this work, most factories and mines use the belt scale, electronic belt scale or nuclear scale installed on the belt conveyor to complete.
电子皮带秤多安装于带式PVC输送带底部，由秤架、称重桥、托辊和传感器等组成.因此，为保证称量的准确，PVC输送带在运行过程中，皮带不要发生跑偏，同时要及时清除附着在带式输送机和电子皮带秤秤架、托辊上的物料。
Electronic belt scale is usually installed at the bottom of belt type PVC conveyor belt, which is composed of scale frame, weighing bridge, idler and sensor. Therefore, in order to ensure the accuracy of weighing, the belt should not deviate during the operation of PVC conveyor belt, and the materials attached to the scale frame and idler of belt conveyor and electronic belt scale should be removed in time.
核子秤是安装于带式输送机上方的计童装置，它虽与PVC输送带不发生接触，但在操作PVC输送带时，人员尽可能不要靠近该装置，以防止受到放射污染。
Nuclear scale is a child counting device installed on the top of belt conveyor. Although it does not contact with PVC conveyor belt, when operating PVC conveyor belt, personnel should not be close to the device as far as possible to prevent radiation pollution.
2、除铁装置
2. Iron removal device
在需要对矿石进行破碎的运输过程中(如在选矿厂)，为清除混入矿石中的铁件，使破碎机安全运输.通常在中、细碎机前的PVC输送带上设置除铁装置。目前常用的除铁装置有:
In the transportation process of ore crushing (e.g. in concentrator), in order to remove the iron mixed in ore and make the crusher transport safely, the iron removal device is usually set on the PVC conveyor belt in front of the medium and fine crushers. At present, the commonly used iron removal devices are as follows:
(1)自动除铁装置:由金属探测器、电磁铁、机械取出装置等几部分组成。
(1) Automatic iron removal device: it is composed of metal detector, electromagnet, mechanical removal device, etc.
(2)带式电磁分离器:一般安装在PVC输送带的卸料处，由机架、电磁铁、电动滚筒、改向滚筒及传送带等部件组成。
(2) Belt type electromagnetic separator: generally installed at the discharge place of PVC conveyor belt, it is composed of frame, electromagnet, electric roller, steering roller and conveyor belt.
(3)悬垂式电磁分离装置:一般由金属探测器和电磁铁组成，但当输送的物料层很厚时，可增设滚筒式电磁分离器。悬垂式电磁分离器清除上、中部矿石中的铁件，滚简式电磁分离器清除下部矿石中的铁件。
(3) Suspension type electromagnetic separation device: generally composed of metal detector and electromagnet, but when the conveying material layer is very thick, drum type electromagnetic separator can be added. The iron parts in the upper and middle ore are removed by the suspended electromagnetic separator, and the iron parts in the lower ore are removed by the rolling electromagnetic separator.
