Quartz Stone Powder Small Grinding Machine

The Reason For The Quartz Stone Powder Small Grinding Machine “Up Belly”

According to the “up belly” nature, the Quartz Stone Powder Small Grinding Machine “up belly” can be divided into two types: “dry type belly” and “wet type belly”. Regardless of the “upswing”, the reason is mainly caused by improper operation, except for the nature of the ore (hardness) and the supplemental ball system.

1, The Amount Of Minerals Is Too Large

Regardless of the type of grinding method used, in order to obtain a stable grinding process, the principle of material in and out balance should be observed, that is, the total amount of ore (the original ore and return) of the Quartz Stone Powder Small Grinding Machine is equal to the amount of ore discharged, and The total amount of ore-mining of the Quartz Stone Powder Small Grinding Machine exceeds the amount of ore discharged, which destroys the principle of material in and out of balance, which naturally leads to “upswing”.

2, The Ore Size Becomes Thicker

In the Quartz Stone Powder Small Grinding Machine that is working stably, when the particle size composition of the ore is changed and the content of coarse particles is increased, if the amount of ore is not adjusted in time, the Quartz Stone Powder Small Grinding Machine cannot maintain stable operation and cause “upswing”. Due to the coarse grinding to the specified fineness, it is necessary to maintain a certain residence time in the Quartz Stone Powder Small Grinding Machine. If the amount of ore is not reduced in time, the coarse-grained material in the Quartz Stone Powder Small Grinding Machine will accumulate more and more, resulting in “upward belly”.

3, The Amount Of Sand Returned Is Too Large

In closed-circuit grinding, unqualified coarse particles are continuously separated from the classifier and returned to the Quartz Stone Powder Small Grinding Machine for re-grinding (the coarse grade returned is called return sand). Although within a certain range, proper increase of sand returning is conducive to increasing the capacity of the Quartz Stone Powder Small Grinding Machine, due to improper operation and the like, the excessive amount of sand returning will destroy the balance principle, resulting in the Quartz Stone Powder Small Grinding Machine “upward belly”.

4, The Amount Of Water Added

In the grinding-grading circuit, add water “front water” (Quartz Stone Powder Small Grinding Machine drainage water) and “post water” (return sand washing water, Quartz Stone Powder Small Grinding Machine to mine water). The change of “pre-water” will lead to changes in the graded overflow fineness and the amount of sand return, which will affect the total amount of the ore-feeding of the Quartz Stone Powder Small Grinding Machine, while the “post-water” will directly affect the grinding concentration. Therefore, for some reason (water pressure reduction, water pipe blockage, etc.), the reduction of the amount of additional water will cause the grinding concentration to be too high, so that the material cannot be discharged, thus causing the Quartz Stone Powder Small Grinding Machine to “rise up”.
