①, mill desk production capacity, refers to under a certain ore and product granularity, within the unit time (h) the amount of ore that the mill can reserve, use the t / (desk • h) to express.
Only when the mill type, specification, the nature of the ore, feed size and product size are got together, can only be condensed to comment on the total group conditions of mills. Henan Hongxing lime rotary kiln, rock impact crusher will be your best choice.
②, mill utilizes factor q, refers to the amount of average effective volume of the unit time per unit mill can process ore, use the t / (m³ • h) to express .
Feed size and product size are similar to the conditions; use the size of the factor q in order to truly reflect the nature of the ore and mill operating conditions. Therefore, it can only cursorily comment on the working conditions of the mill.
In the process of grinding, ball mill, raymond mill and rod mill will be used; grinding effect is good or bad, generally it is measured by the grinding granularity, production capacity and mill operating rates. The former is the quality indicators, the latter two are number indicators.
Mill’s production capacity
Operating rate, also known as the rotating rate. It means the percentage of the actual number of hours of grinding and classification unit accounts total calendar hours, in the production, each mill is calculated once a month, the annual is accumulated totally and monthly average. The level of the mill operating rate reflects the management level of the concentrator. In this way, it can also expose and analyze the reason for impacting the abnormal operation of grinding classification unit, and take effective improvement measures.
Grinding product fineness is usually use the 200 mesh of standard sieve to sieve products and use the percentage of the amount under the screen accounted the product total amount to express, as the grinding fineness -200 mesh covers 60% or-0.075mm covers 60%. The larger of the percentage, the finer of the product is.
