It is the main part of the belt conveyor and plays the role of carrying materials. It is widely used in iron and steel, coal, metallurgy (content: extract metal or metal compounds from ore), chemical industry, building materials, grain and other industries. Compared with other transportation modes, it has the advantages of safe operation, convenient use, easy maintenance, low freight and continuous operation（ In a certain range, it has become the substitute of highway and railway transportation (using one material to replace another (mostly the strong to replace the weak).

　　此種輸送帶適用于一般條件下輸送無特殊腐蝕(釋義:指腐爛、消失、侵蝕等)常溫塊狀、粉狀物料 。大傾角擋邊輸送帶又叫裙邊隔板輸送帶， 是由基帶、擋邊、橫隔板3部分組成。擋邊起防止物料測滑撒落的作用。解決了普通帶和花紋帶所不能達到的輸送角度；還可根據(jù)使用環(huán)境，設(shè)計成完整、獨立的輸送系統(tǒng)，避免了間斷輸送和復(fù)雜輸送的提升系統(tǒng)。可沿水平、傾斜、垂直和變角方向輸送各種散裝物料，從煤、礦石、沙子到化肥和糧食等。

　　This kind of conveyor belt is suitable for conveying bulk and powdery materials without special corrosion under general conditions. The high angle edge blocking conveyor belt, also known as skirt partition conveyor belt, is composed of baseband, edge blocking and diaphragm. The edge guard is used to prevent the material from sliding and scattering. It solves the conveying angle that ordinary belt and pattern belt can't reach; it can also be designed as a complete and independent conveying system according to the use environment, avoiding the lifting system of discontinuous conveying and complex conveying. It can transport all kinds of bulk materials, from coal, ore, sand to fertilizer and grain, along the horizontal, inclined, vertical and variable angle directions.

　　強力層為重型棉帆布純棉、滌棉帆布 。拋丸機履帶因為拋丸機履帶是非常的特種膠帶，各種技術(shù)指標(biāo)不同于普通的橡膠帶，不被社會上的普通橡膠帶廠掌握，所以質(zhì)量良莠不齊，普通消費者需要學(xué)會鑒別，由于生產(chǎn)拋丸機的廠家比較多，各家的尺寸會有差別，所以選型時需要特別注意，一定要看機器說明書，按照說明書選型，必要時可以向履帶生產(chǎn)廠咨詢，因為的履帶生產(chǎn)廠一般備有各種型號拋丸機履帶的技術(shù)規(guī)范和庫存。

　　The strong layer is high-quality heavy-duty cotton canvas, pure cotton, polyester cotton canvas. Because the crawler of shot blasting machine is a very professional special tape, various technical indicators are different from the ordinary rubber belt, which is not mastered by the ordinary rubber belt factory in the society, so the quality is uneven. Ordinary consumers need to learn to identify. Because there are many manufacturers of shot blasting machine, and the size of each will be different, so special attention should be paid to the selection, and the machine must be looked at According to the instruction manual, select the type according to the instruction manual. If necessary, consult the crawler manufacturer, because the professional crawler manufacturer generally has the technical specifications and inventory of the crawler of various models of shot blasting machine.

　　普通棉帆布輸送帶情況如下：

　　The general cotton canvas conveyor belt is as follows:

　　a、 覆蓋（Cover)層物理機械性能：

　　a. Physical and mechanical properties of cover layer:

　　b、 層間粘合強度（strength)

　　b. Interlaminar bond strength (strength)

　　c、 全厚度拉伸性能：

　　c. Full thickness tensile properties:

　　（1） 帶的縱向拉伸強度（strength)不低于如下標(biāo)稱值：100、125、160、 200、250、315、400N/mm

　　(1) The longitudinal tensile strength of the tape shall not be less than the following nominal values: 100, 125, 160, 200, 250, 315, 400N / mm

　?。?） 帶的全厚度縱向拉斷伸長率不小于10% . 帶的全厚度縱向參考力伸長率應(yīng)不大于4% 。

　　(2) The longitudinal elongation at break of the full thickness of the belt shall not be less than 10%. The elongation at the longitudinal reference force of the full thickness of the belt shall not be more than 4%.

　　d、 直線度：不大于25mm 。拋丸機履帶由三層組成，更外面是上覆蓋膠，直接與被清理的工件接觸，接受鋼丸的擊打，所以磨損劇烈，承受很大的破壞力，上覆蓋膠的壽命幾乎就是履帶的壽命，上膠同時也是暴露在更外面的橡膠，質(zhì)量好壞能看到和摸到，好的橡膠有彈性，橡膠都是模具做出來的，為了讓模腔內(nèi)的氣體排出，模具都有排氣的細孔，會在橡膠上留下排氣線，用手拉動排氣線，感覺彈性足，則橡膠好。

　　d. Straightness: no more than 25mm. The crawler of shot blasting machine is composed of three layers. The outermost layer is covered with rubber, which directly contacts with the cleaned workpiece and is hit by steel shot. Therefore, it is severely worn and bears great destructive force. The life of the upper covered rubber is almost the life of the crawler. The upper rubber is also the rubber exposed to the outermost layer. The quality can be seen and felt. The good rubber is elastic, and the rubber is made by mold Come on, in order to let the air in the cavity of the mold be discharged, the mold has the vent holes, which will leave the vent line on the rubber. Pull the vent line by hand, feel the elasticity is enough, then the rubber is good.
