By 2019, prm has built 6 advanced manufacture bases which cover a total area of over 1,200,000 m 2, contain various of crusher and grinding mill production line, such as sand making machine, mobile crusher, vibrating screen and Raymond mill, etc. And the annual production value can reach RMB 5 billion.
The experiments are carried in stirred ball mill (prm) with ball size of 1.5mm and tip velocity 7.6m/s. The product obtained from industrial ball mill at six hours of grinding was taken and further milled in prm. The desired product was obtained within 15 minutes. The results of the size analysis are shown in Fig.2.
LM Vertical Grinding Mill. Based on the absorption of advanced technologies of famous international corporations and 30 years' experience in grinding mill production, prm has launched the LM Vertical Grinding Mill which integrates five functions of crushing, grinding, powder selection, drying and material conveying.
Grinding Mill. Grinding mills are mainly used in metallurgy, building materials, chemical engineering, mines and other fields. The grinding mill is a collective word which can be classified into the vertical grinding mill, the pendulum roller mill, the superfine grinding mill, the trapezoidal grinding mill, the medium-speed grinding mill and so on.
In grinding, operating Efficiency compares the operating work index of a comminution machine to the Bond work index from bench scale crushing and grindability tests or/and pilot plant tests. Economic Efficiency is comparing the income from production to the planned income from production. Energy as consumed in comminution machines and the required energy as determined, from bench scale .
