What Factors Will Influence The Ore Grinding Efficiency

The ore grinding process is a core step using ball mills as the Vertical Roller Mill key equipment in the ore beneficiation production line. there are factors influencing the ore grinding efficiency of the ball mill. here our experts will analyze two main factors.
1.ore concentration
The ore concentration or the ore density has much effect on the grinding efficiency. as too high concentration will prolong the ore grinding time, minerals will flow quite slowly inside the ball mill, thus leading to over grinding. moreover, in the high concentration ore pulp, coarse ore grains are hard Quarry Crusher to sink and will flow with the pulp.
If the ore density is too low, minerals will flow quickly and the grinding time is shortened, also resulting in coarse ore running off. at the same time, large density ore grains will deposit at the bottom of the ore pulp, which will also cause over grinding.
When operating the ball mill, users need to keep the ore density at a proper value by controlling the water supply volume. generally speaking, ore density of coarse grinding materials is about 75%-85% and that of fine grinding materials is 65%-75%. if the ore grain size is not in the reasonable range, it will seriously influence the ore grinding efficiency.
Crusher Machine 2.operation of users
Users operation will of course influence the ore grinding efficiency of ball mills. for example, in the closed ore grinding process, if the sand return rate is too high and even exceeds the normal handling capacity of the ball mill, it will lead to the coarse ore running off.
Concrete crusher is also called jaw crusher, which applies on the metallurgical, mining, building, chemical, water and railway sectors, as crushing, broken compressive power 250mpa following varieties of ores and rocks functions. concrete crusher chamber depth and no dead zone, can greatly boost the ability to feed and manufacturing. in addition, concrete crusher construction is easy, reputable, low operating fees. concrete crushing machine also has its significant crushing ratio, uniform particle size goods; gasketed discharge opening adjustment device, trustworthy and handy, adjustment selection, versatility characteristics of large gear.
