由武汉工业大学和梨树硅灰石矿业公司共同攻关开发研制的LPM-680流化床式气流磨于1993年11月通过了由国家建材局组织的技术鉴定。该设备对硅灰石、滑石、锆英砂、重晶石、方解石、云母等矿物进行了粉碎工艺试验,试验证明该机适用于非金属矿及其它工业部门微粉粉碎。该机采用了对心逆喷射原理与气固两相流设计,高效平卧式高速涡轮结构及精确的分级机变速和磨内料位控制系统,在喷嘴型
The LPM-680 fluidized bed jet mill developed by Wuhan University of Technology and Lishi Wollastonite mining company passed the technical appraisal organized by the State Bureau of Building Materials Bureau in November 1993. The equipment for wollastonite, talc, zircon sand, barite, calcite, mica and other minerals were crushed experiment, the test proved that the machine is suitable for non-metallic mineral and other industrial sectors of fine powder grinding. The machine uses the inverse heart jet theory and gas-solid two-phase flow design, high-speed horizontal turbine structure and accurate grading machine speed control and material level control system in the nozzle
