鞍山式赤铁矿石球磨磨矿动力学研究
发布时间：2018-12-30 13:02
【摘要】：应用MATLAB软件对鞍山式赤铁矿磨矿瞬时速度进行研究.矿料在球磨过程中经历"粗粒级快速碎磨-中粒级动态碎磨-中粒级单一碎磨"三个固有阶段.0.043~0.031 mm粒级比0.105~0.043 mm粒级更早进入动态碎磨状态,容易出现细粒级过粉碎.与圆锥破碎机产品相比,高压辊磨机产品在磨矿中各阶段的转折时间显著缩短,但会更早出现细粒级过粉碎.生产中通过提高高压辊磨机产品的入磨量来缩短球磨时间,在提高选厂的处理能力的同时减弱排矿产品细粒级过粉碎.
[Abstract]:The instantaneous grinding velocity of Anshan hematite is studied by MATLAB software. There are three inherent stages in the process of ball milling: "coarse particle fast grinding, medium grain dynamic grinding and medium grain single grinding". The particle size of 0.043 ~ 0.031 mm is in dynamic grinding state earlier than that of 0.105 ~ 0.043 mm. It is easy to smashing fine particles. Compared with conical crusher products, the turning time of high-pressure roller mill products in each stage of grinding is shortened significantly, but the fine grain-grade over-comminution will occur earlier than that of conical crusher products. In production, the ball milling time is shortened by increasing the grinding quantity of high-pressure roller mill products, and the fine grain grade over-crushing of ore discharging products is reduced while the processing ability of the separation plant is improved.
