煤礦用阻燃抗靜電pvc輸送帶、PVG整芯輸送帶采用整體帶芯作為骨架材料，經(jīng)浸漬，上下覆蓋膠具有極女子的抗靜電、阻燃等性能的PVG(橡膠面)或PVG(塑膠面)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.
煤礦用輸送帶用途：產(chǎn)品具用不脫層、難燃燒、導(dǎo)靜電、抗縱向撕裂、抗沖擊力、抗水侵蝕等優(yōu)良性能，適用于煤礦、井下及其它易燃場(chǎng)合，輸送煤炭、化工類等物品。PVC整芯輸送帶用于傾角16°以下的干燥條件的工作環(huán)境，PVG整芯輸送帶可用于潮濕的工作境。
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輸送帶有什么作用，有哪些裝置？PVC輸送帶在礦石運(yùn)輸過(guò)程中，與其他作業(yè)相銜接，為保證相關(guān)的作業(yè)正常運(yùn)轉(zhuǎn)，常在有的PVC輸送帶上安裝附設(shè)裝置，為整個(gè)生產(chǎn)過(guò)程的計(jì)量、服務(wù)。
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、皮帶秤
1. Belt scale
為加強(qiáng)礦山生產(chǎn)過(guò)程中的計(jì)劃管理工作，一般都要對(duì)每日進(jìn)人的原礦量和產(chǎn)出的精礦量進(jìn)行計(jì)量。這項(xiàng)工作除了一些小型廠礦采用人工計(jì)量的方法來(lái)完成外，大部分廠礦都采用在帶式輸送機(jī)上安裝皮帶秤、電子皮帶秤或核子秤來(lái)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.
電子皮帶秤多安裝于帶式PVC輸送帶底部，由秤架、稱重橋、托輥和傳感器等組成.因此，為保證稱量的準(zhǔn)確，PVC輸送帶在運(yùn)行過(guò)程中，皮帶不要發(fā)生跑偏，同時(shí)要及時(shí)附著在帶式輸送機(jī)和電子皮帶秤秤架、托輥上的物料。
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.
核子秤是安裝于帶式輸送機(jī)上方的計(jì)童裝置，它雖與PVC輸送帶不發(fā)生接觸，但在操作PVC輸送帶時(shí)，人員盡可能不要靠近該裝置，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、除鐵裝置
2. Iron removal device
在需要對(duì)礦石進(jìn)行破碎的運(yùn)輸過(guò)程中(如在選礦廠)，為混入礦石中的鐵件，使破碎機(jī)運(yùn)輸.通常在中、細(xì)碎機(jī)前的PVC輸送帶上設(shè)置除鐵裝置。目前常用的除鐵裝置有:
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)自動(dòng)除鐵裝置:由金屬探測(cè)器、電磁鐵、機(jī)械取出裝置等幾部分組成。
(1) Automatic iron removal device: it is composed of metal detector, electromagnet, mechanical removal device, etc.
(2)帶式電磁分離器:一般安裝在PVC輸送帶的卸料處，由機(jī)架、電磁鐵、電動(dòng)滾筒、改向滾筒及傳送帶等部件組成。
(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)懸垂式電磁分離裝置:一般由金屬探測(cè)器和電磁鐵組成，但當(dāng)輸送的物料層很厚時(shí)，可增設(shè)滾筒式電磁分離器。懸垂式電磁分離器上、中部礦石中的鐵件，滾簡(jiǎn)式電磁分離器下部礦石中的鐵件。
(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.
