The middle trough of the scraper conveyor is one of the key parts of the scraper conveyor, and it is the fuselage of the scraper conveyor. Only the volume and quality of the scraper conveyor occupies about 70% of the scraper conveyor machine. Scraper parts manufacturer Henan shuangzhi below for you to introduce the scraper middle trough. As an important spare part of the scraper conveyor, the middle trough of the scraper is not only the bearing mechanism of the material and the scraper chain, but also the important fulcrum of the hydraulic support. Each scraper is generally equipped with more than 100 middle slots, the length of the middle slot is mainly 1.5m and 1.75m two types. Therefore, the service life of the scraper and the transport volume are largely determined by the service life of the middle slot. The middle slot is mainly made of the groove side and the middle plate. The material is mainly 16Mn and ZG30SiMn2 of high manganese steel. According to the different manufacturing technology of the middle slot, the middle slot can be divided into welding middle slot, casting middle slot and integral casting middle slot. According to the different structure of the central trough, the central trough can be divided into the open bottom middle trough and the back end middle trough. The middle groove can be divided into the middle groove of the single and the middle groove of the double. The central trough of the scraper is in direct contact with the material, coal gangue and scraper chain, which is easy to be affected by it and will cause scraping and wear for a long time. The middle plate, bottom plate and groove top of the middle slot are the most prone to wear. The main wear forms are abrasive wear, fatigue wear, adhesive wear and corrosion wear. Henan Shuangzhi, as a highly praised scraper conveyor accessories manufacturer in the industry, improves the abrasion resistance of the central slot of the scraper by adopting wear-resistant materials and optimizing the surface strengthening technology of the central slot.
