High-pressure micro-powder mill is mainly used for 500 kinds of materials’processing of ultra-fine powder, such as feldspar, talcum, barite, marble, limestone etc. Fineness is between 500 mesh (25 mm) -1250 mesh (10 mm), the most fineness is 2500 mesh (5 mm).
Working principle:
High-pressure micro-powder grinding machine is as same as the R series of Raymond mill. Micro-grinding is set up high-pressure spring in the grinding device, So the pressure between grinding roller and grinding ring increase 1.2 times. When the grinding roller and grinding ring reaches a certain worn, adjust the length of high-pressure spring to keep the constant grinding pressure between grinding roller and grinding ring. In order to ensure quality and stability.While, through the technological improvements for various components in the milling devices, The contact area between roller and grinding ring reaches the maximum, avoiding the phenomenon about general milling machine that the small particles of materials in the rugged gaps can not be continuously crushed. According to the calculation for gas flow Bonu equations and simulated testing results,Changed the blade geometry in the fineness grading machine, re-adjusted the angle and relative gap, so that the ultra-fine powder enter the classification can be sorted out effectively and precisely.
