短距离块原煤刮板输送机的改造实践

Reform Practice of Short-Distance Scraper Conveyor Applied to Raw Coal

摘要: 刮板输送机是煤矿、选煤厂常用的运输机械，尤其在物料比例分配上起着重要作用。由于刮板输送机在使用上存在明显的优缺点，所以合理选用刮板输送机就是关系到选煤厂安全生产运营和成本管理的一个重要问题。本文就中煤新集二矿选煤厂入洗块原煤刮板输送机的改造经验谈一谈刮板输送机在短距离输送大块物料时的选型和应用。

Abstract: Scraper conveyor is a common transportation machinery used in coal mines and coal preparation plants, especially in the distribution of materials. Due to the obvious advantages and disadvantages of the scraper conveyor, the reasonable selection of the scraper conveyor is an important issue related to the safe production operation and cost management of the coal preparation plant. In this paper, we discuss the selection and application of scraper conveyors for conveying large blocks of materials in short distances with regard to the transformation experience of raw coal scraper conveyors in the coal preparation plant of China Coal New Coal Mine.
