Using slag made from refined processing of slag cement, slag powder, slag powder, slag Portland cement, slag cotton, blast furnace slag, granulated blast furnace slag powder, copper slag, slag vertical mill. Save energy consumption, rotary dryers for slag drying has important effect to industrial production. For project design USES th dryers, rotary dryer internal device select copy plate form, according to the production can be sure of the specifications of the dryer. Material and heat of flue gas from the inlet into the dryer at the same time, the drying of materials. From textbooks provide coal used in the design of fushun bituminous coal of flue gas were calculated, the motor power to review and determine the flow rate of the exhaust gas out of the dryer, electrical power, gas and the structure of the dryer. According to the exhaust and dustiness choose dust collecting equipment and ventilation equipment and piping layout. Key words: 60000 tons of slag heating drying machine structure gas dust collection equipment ventilation equipment piping layout. 明德至善 博學(xué)篤行 5 第一章 前言 課程設(shè)計(jì)背景 隨著現(xiàn)今工業(yè)的發(fā)展，最離不開(kāi) 的也是資源的開(kāi)采 和利用 ，由于 礦渣 資源 有點(diǎn) 已是不可再生資源， 礦渣將成為 工業(yè)賴以生存和發(fā)展的物資基礎(chǔ)，在工業(yè)的發(fā)展和日常的生活中起作舉足輕重的作用 。 隨著圓筒的轉(zhuǎn)動(dòng)物料受重力作用運(yùn)行到較底的一端。 在內(nèi)部結(jié)構(gòu)上實(shí)現(xiàn)了創(chuàng)新，強(qiáng)化了對(duì)已分散物料的清掃和熱傳導(dǎo)作用，
