Quartz Stone Powder Small Grinding Machine Detail

The reason of making the Quartz Stone Powder Small Grinding Machine “belly up”

According to the properties of “upper abdomen”, the “upper abdomen” of Quartz Stone Powder Small Grinding Machine can be divided into two types: “dry abdomen” and “wet abdomen”. Whether it is “upward fluctuation”, the reason is mainly due to improper operation, in addition to the nature of ore (hardness) and auxiliary ball system.

1. The mineral quality is too high

No matter which grinding method is used, in order to obtain a stable grinding process, the principle of material in and out balance should be observed, that is, the total ore amount of ore (raw ore and returned ore) is equal to the ore amount discharged by the Quartz Stone Powder Small Grinding Machine, and the total mining amount of the Quartz Stone Powder Small Grinding Machine exceeds the ore amount discharged, which destroys the principle of material balance and imbalance, and naturally leads to “rising”.

2. Ore size thickening

In the stable operation of the Quartz Stone Powder Small Grinding Machine, when the particle size composition of ore is changed and the content of coarse particles is increased, if the ore volume is not adjusted in time, the Quartz Stone Powder Small Grinding Machine will not be able to maintain stable operation and lead to “rise”. Due to rough grinding to the specified fineness, it is necessary to maintain a certain residence time in the Quartz Stone Powder Small Grinding Machine. If the ore quantity is not reduced in time, the coarse materials in the Quartz Stone Powder Small Grinding Machine will accumulate more and more, resulting in “belly up”.

3. The amount of sand returned is too large

In the closed-circuit grinding, the unqualified coarse particles will be separated from the classifier continuously, and then returned to the Quartz Stone Powder Small Grinding Machine for re grinding (the returned coarse class is called return sand). Although in a certain range, the proper increase of the amount of returned sand is conducive to improving the production capacity of the Quartz Stone Powder Small Grinding Machine. Due to improper operation and other reasons, excessive amount of returned sand will destroy the balance principle, leading to the “upper abdomen” of the Quartz Stone Powder Small Grinding Machine.

4. Added water amount

In the grinding grading circuit, add water “front water” (Quartz Stone Powder Small Grinding Machine drainage) and “back water” (sand washing water, Quartz Stone Powder Small Grinding Machine return to mine water). The change of “front water” will lead to the change of classification overflow fineness and sand return quantity, which will affect the total amount of ore feeding of the Quartz Stone Powder Small Grinding Machine, while “back water” will directly affect the grinding concentration. Therefore, for some reason (reduced water pressure, clogged water pipes, etc.), reducing the additional water will lead to too high grinding concentration, so that the material can not be discharged, resulting in the “up” of the Quartz Stone Powder Small Grinding Machine.
