Raw material grinding mill machinery stand at attention when used to stabilize the bed, keeping the material layer uniform and stable and avoid uneven thickness, appropriate adjustments classifier speed and grinding pressure, so as not to stand strong vibration mill. If you have the drive and the analysis of Grinding mill sump fever how to do it? Shanghai World state of small series to bring you a look at how to solve these problems.
(1) how to stabilize the bed
The bed is Grinding mill stable normal production and standards to ensure that the material milled at commissioning stage should be based on the thickness of material to find its relationship with the mtw milling machine output. The thickness of the material layer is closely related with the finished product fineness and yield, lower material layer is too thick grinding efficiency, the material layer is too thin will cause vibration. Here is a simple code of practice, roll increased, resulting powder is much thinner material layer; rolling reduction, disc material thicker, more appropriate to return the material, the material layer thickens, adjust the material layer the thickness can be changed by a corresponding roll size. In addition, Grinding wind speed within the mill may also play a role in stabilizing the bed, and the scm ultrafine mill wind speed increase, increase the internal circulation of material layer thickness, lower wind speeds, reducing the inner loop, the material layer thinning. Under normal circumstances the normal thickness of the material bed 40 ~ 50ram.
(2) how to control the grinding pressure
The most direct effect from the production point of view, the grinding pressure is the main factor affecting the mill output, mill grinding efficiency and power. Grinding mtm trapezium grinder is realized by means of milling process of the bed subjected to high pressure and the pulverized material, the pressure increases to increase the yield, but after reaching a certain critical value does not change, the increase in pressure followed by a power increasing thereby increasing the energy costs of the user. Therefore, we recommend that many consider to be the grinding pressure power consumption, material properties, as well as the volume of feed finished material requirements and other factors in the production process for the appropriate and reasonable wind speed roll to form a good grinding structure. Ensure the wind speed stability, appropriate material thickness, Grinding mill grinding to ensure results.
(3) Grinding mill gear and analyze how do sump fever
Check the oil viscosity lard deposit, threaded pump oil does not go on to play the upper bearing in oil; check the oil grade and viscosity is consistent with the requirements; check analysis machine running direction.
(4) the main factors affecting the production capacity of the mill stand
Feed rate reasonable control; adjust grinding pressure and material thickness; the adjustment of product fineness; stand mill circulating air inside the relationship with the wind, the wind speed.
