Product DescriptionProduct DescriptionThe underground scraper conveyor produced by Henan Shuangzhi is a mechanical equipment used for material transportation in coal mines. It mainly consists of the head, middle trough, tail, scraper chain and accessory parts, and is often combined with coal mining machines and hydraulic supports to form a fully mechanized mining system. It is suitable for transporting coal in gently inclined medium-thick or thick coal seams, thin or extremely thin coal seams in blasting mining, ordinary mining, advanced ordinary mining, fully mechanized mining and fully mechanized caving mining working faces in coal mines. It can also be used for transportation in tunneling roadways and along the goaf. High-strength Design: The high-strength mining round link chain is used to drive the scraper, and the concave-toothed sprocket is selected for driving. It features a large load capacity, long chain life, and high strength.Sealed Structure Design: The fully sealed structure design reduces noise, minimizes environmental pollution, prevents dust leakage, and improves the working environment.Wear-resistant Material Application: The upper and lower chain tracks and side plates of the trough are designed with wear-resistant materials and stainless steel plates.Bendable Design: The middle trough can be bent by 2° to 4° through the hydraulic pushing device, meeting the requirements of the longwall working face advancement.Long service life: Key components are made of high-strength wear-resistant materials, significantly extending the equipment's service life.Smooth operation: The equipment operates smoothly, safely and reliably, with low noise and high conveying efficiency.BrandSZhiOriginZhengzhou, Henan ProvinceStructureChain ConveyorProduction Capacity50 Pieces/YearConveyor Capacity200~1000 T/HInstallation Angle0–30°Drive TypeElectric MotorMain ProductsCompany ProfileHenan Shuangzhi Machinery Equipment Co, Ltd., located in Zhengzhou (the "Green City" capital of Henan Province),operates from its manufacturing facility in Wuzhi industrial Park, With a workforce of over 300 employees, including morethan 50 senior engineering and technical personnel, the company has established itselfthrough robust technical expertise,advanced manufacturing processes, high-quality coal mining machinery products, and stringent quality control standardsThese competitive advantages have earned Henan Shuangzhi a solid reputation in the coal mining machinery marketmaking it a designated forging component supplier for multiple. coal mining enterprises.
