what aspects of grinding mill need adjust to Powder fineness

Powder fineness are generally has a mesh definition, the fineness of powder determines the performance of micro powder grinding mill equipment, a good grinder mill is powder fineness. Due to mill design is not according to each kind of material, each type of mill can be processing a variety of materials, and some customers after purchase the mill is not always only the processing of a material and a fineness, sometimes change material or adjust the fineness of discharge, and this needs to adjust grinding mill, has reached the customer required the fineness of discharge and output.

So how to adjust? grinding mill discharge fineness and production related to those factors? We first to mill as an example. Only from the perspective of mill energy utilization rate, if the grinding specific material, require certain fineness, it needs some fine tune for grinding mill equipment. Each kind of materials is not with the best grinding speed is different, so there is no unified formula can accurately calculate the linear velocity of rotor in crushing material in the material level of granularity of best fit.

Grining mill in the process of work the most headache problem is bad grinding fineness, the grinding powder often can not meet the standard, sometimes can only again and again to rework, how to quickly prepare the adjustment of grinder grinding fineness of powder? My company in grinding mill research summarizes several common to adjust fineness method.

1, grinding mill main motor adopts frequency control of motor speed, the grinding machine spindle speed can be adjusted greatly, thus changing roller pressure to the grinding ring (centrifugal force), the positive pressure ultimately change grinding effect. Grinding to apply further increase output after meal, the host and the blower motor power increasing.
2, limit roller swing limit position, make the gap formed between grinding roller and grinding ring during operation, and the clearance can be adjusted freely, which can significantly adjust the grinding strength and the control of particle size.
3, change the air conveying system of technical parameters, increase the flow blower, wind speed and air volume in the overhaul grinding. According to principle in the air separation, air separation size is proportional to the through the rotor flow.
