vertical roller mill material grinding fineness control

In the use of grinding material grinding, we design the machine in the two control of the material fineness, but some users reflect the machine grinding material of the product is still more difficult to control, so what is the reason, the following is for you to simply answer these questions.
LM vertical roller mill is a kind of special milling machine, it compared to other milling equipment, the most special place lies in the grinding principle of it is material disc grinding, namely the ore material placed on the disc, by grinding and grinding to obtain the finished material, but in the tray grinding, grinding between the roller and the grinding disc the size of the distance control level of grinding efficiency (grinding efficiency is mainly refers to the finished material fineness qualified material to occupy the proportion of high and low), but also control the size of the milling yield, so we need to pay special attention to.

Using vertical mill for the production of flour, some users reflect the material milling refined makings is fineness variation in size is relatively large, difficult to control, sometimes fineness will be too large, and sometimes fineness would be too small, so if you want to understand the method of controlling fineness of materials size, and according to the user's needs. We also summarize the following points, hope to users of the production of flour can bring some help.

First of all, according to the principle of vertical mill grinding we know, the distance between the size of grinding roller and grinding milling machine determines the level of efficiency, when the distance between the grinding roller and the grinding disc is reduced, quantity of fine powder will increase, thereby increasing fineness of grinding, whereas the amount of subdivision decreases, the grinding fineness will secondly, in the milling machine is reduced; the production of flour, powder selecting machine also plays an important role, the fineness of powder material can be controlled to a certain extent, so we can start from the angle of the powder selecting machine, is connected with the motor by adjusting the separator, to adjust the powder selecting machine speed, so as to realize the control of powder material fineness, high speed powder machine by adjusting the fineness of finished products, will increase, otherwise it will reduce.

Above is the vertical mill refined makings is fineness size control method, and users need to pay attention to is, the grinding roller is used to adjust the is hydraulic control, users have to learn to use hydraulic station to adjust the level of distance and disc grinding, and then achieve the finished product fineness regulation.
