古书院矿选煤厂是一座设计入洗能力300万t/a的矿井型选煤厂,1992年建成投产。块精煤产品筛分系统沿用19.58年建矿时期的老系统,根据当时市场需求,块煤产品品种分大块(50～80 mm)、中块(25～50 mm)和小块(13～25 mm)三个品种,筛分系统采用二次筛分,即13～80 mm粒级产品经重型筛筛分后,50mm以上粒级直接入仓,.50mm以下粒级再经概率筛筛分后分出中块(25～50 mm)和小块(13～25 mm)产品。近年来,随着市场需求的不断变化,块煤产品
Gushuyuan Coal Preparation Plant is a design coal washing capacity of 3 million t / a mine coal preparation plant, put into operation in 1992. According to the market demand at that time, the varieties of lump coal products were divided into large blocks (50 ~ 80 mm), medium blocks (25 ~ 50 mm) and small blocks (13 ~ 25 mm) three varieties, the screening system uses the second screening, that is, 13 ~ 80 mm size products through the heavy sieve, 50mm above the grain size direct warehousing, After the separation of blocks (25 ~ 50 mm) and small pieces (13 ~ 25 mm) products. In recent years, with the changing market demand, lump coal products
