How to determine the reasonable load of the grinding body of the ball mill

By -

 The configuration of the grinding body of the ball mill will have a great influence on the output quality of the ball mill. If there is a gradation of the grinding body, then the conditions such as the load of the grinding body must be fully considered. The following briefly introduces the calculation method of the grinding body.

The first condition is the filling rate of the abrasive body. So what is the filling rate of the abrasive body? The percentage of the filling volume of the grinding body compared to the effective volume is called the filling rate of the grinding body. Generally speaking, if the filling rate of the grinding body is too high or too low, the grinding efficiency of the mill will be too low. For the grinding body filling rate greater than 32%, you can use the formula to calculate:

Φ0=113-126H/Di

Since there are many influencing factors of the grinding body, it is necessary to find a better filling rate in the production and adjust the equilibrium state according to the degree of change of the influencing factors.

Then we have to mention the loading capacity of the grinding body. What is the loading capacity of the grinding body? It is the quality of the grinding body loaded into the mill (or in the container), and the size of the load mainly depends on the filling rate of the mill. The calculation formula of the loading capacity of the grinding body:

G=VΦ0

                                                G=0.00785Di2LΦ0

It can be seen from the above that G——loading capacity (t), V——effective volume (m3), Di——effective diameter (m), L——effective length (m), Φ——filling rate (%), P ——Bulk density (t/m3)

Selection of spodumene flotation reagents

By -

At present, the  beneficiation methods of spodumene  mainly include: manual separation, thermal disintegration, magnetic separation, resuspension method,  flotation method  and combined beneficiation method. Among them, the flotation method of spodumene is the most studied in the laboratory and the most widely used mineral processing method in industry. 1. Cationic collectors The cationic collectors used in the flotation of spodumene ore are mainly amine collectors, which flotate gangue minerals such as quartz, feldspar and mica under acidic conditions, and leave the spodumene at the bottom of the tank. This method is often used in the roughing of spodumene, and cannot directly obtain spodumene concentrate with higher purity, and needs to be used in conjunction with other sorting methods. In production practice, Yan Gengsheng used  the process of flotation of spodumene  with mixed soap and diesel oil under alkaline conditions after flotation of mica with phylloylamine under acidic cond

How to use inclined plate thickener for tailings dry discharge

 Tailings treatment is an important part of mine production. Concentration in dry tailings discharge is an important link in achieving dry stacking. It not only directly affects the processing capacity of filter equipment, but also affects the resistance of filter cakes. The particle is resistive to the filter cake, so according to the characteristics of iron tailings, there is a new type of thickener . The flow of tailings slurry in the thickener is ideally slow. As soon as the solid particles leave the flow layer, they will be considered as sediment. This model is also called shallow sedimentation. The sedimentation occurs in the void between the inclined plates. Within the cavity, but due to the small spacing between the inclined plates, it creates favorable conditions for the formation of laminar flow. The clarified overflow water moves upward along the inclined plate space, and the solid particles settle between the two plates, and only need to settle to a small distance to fall o

A new type of coarse particle flotation machine for rough grinding and flotation in mines

By -
 Coarse ore flotation has always been one of the key technologies for mine coarse grinding and flotation to reduce energy consumption. An iron ore plant in Anhui Province has a very small content of mica in the iron ore of the first grinding product. Recovery value. However, there are generally two ways to recover mica at present: one is coarse-grained regrind and reselection; the other is to choose equipment suitable for coarse-grained mineral flotation. However, during the inspection of the production site, it was found that many of the mica minerals in the second-stage grinding products in this iron ore did not meet the particle size requirements of flotation, and the density of mica was small, and most of them showed flaky structure. The overflow of the cyclone ran out, causing the inspection and screening operation to be blocked first, so regrinding is not suitable for the recovery of coarse mica.     The design principle of coarse-grained flotation machine is that coarse-grained
