高铬辊子对辊破碎机在磷矿石加工中的应用

Application of High-chromium Double Roller Crusher for Phosphate Rock Crushing

介绍了磷矿破碎生产中各种破碎机的作用和特点,重点阐述了磷矿细碎设备对辊破碎机的选型核算和结构特点,经过安装使用和生产实践,认为高铬铸铁辊子对辊破碎机使用成本低,破碎的磷矿石粒度均匀,比高锰钢的寿命长,是磷复肥生产过程中磷矿进入球磨机之前的最佳细碎设备。

The functions and features of various crushers for phosphate rock crushing are described,and the selection calculation and construction features of the double roller crusher for phosphate rock crushing are highlighted. Through installation and production practice,it is concluded that the highchromium cast iron double roller crusher offers low operating cost,the crushed phosphate rock has uniform particle size,and it has longer life than highmanganese steel,and it is the best crushing equipment before phosphate rock entering the ball mill during phosphate compound fertilizer production.
