Is grinding fineness of ball mill as thin as possible?

Ball mill as important equipment in ore beneficiation line, grinding is the main task.When choosing ball mill equipment, Is the fineness of grinding as thin as possible?Let me give you the right answer.

In practical production, in order to improve the efficiency of magnetic separator,some dressing plant manufacturers think that the thinner grinding fineness, The more convenient to separate.However, This operation let beneficiation production line go a lot of detours, not only reduce the magnetic separation recovery, but also increased the company's operating costs.Given that many users leave a lot of detours, expert proposal that should choose the ball mill according to the demand of dressing plant and the nature of each ore to choose grinding fineness requirements.
Experts point out that only suitable for the grinding fineness is necessary condition for the useful minerals and gangue minerals separation.Therefore, this traditional concept is wrong.

what is the production process of ore beneficiation line?

Ore Beneficiation Line is composed of ball mill, classifier, magnetic separator, flotation machine, thickener, dryers and other major equipment.Cooperate with the feeder, hoist, transfer machine,it can form a complete beneficiation production line.This production line has high efficiency, low energy, high capacity, reasonable economy, etc.

First of the jaw crusher preliminary broken, after the broken to a reasonable fineness by elevator, feeder evenly into the ball mill, ball mill for ore crushing, grinding.After ball mill grinding of ore fines into the next process: classification.With different proportion of solid particles in the liquid precipitation rate of different principle,spiral classifier washes ore mixture grading.Due to a variety of minerals magnetization coefficient, using magnetic force and mechanical force will separate magnetic materials of mixture.

Pay attention to several issues of cone crusher running under a high temperature

The workload of cone crusher is very big. The connectivity between the parts is strong. Once there was a problem in a tiny component, it will delay the normal operation of other components, posed great challenges to the stability of the cone crusher especially in the high temperature.
On the one hand, in the case of high temperature, the lubrication effect of cone crusher will become very poor, therefore, it can consider adding some cooling devices for the cone crusher when cone crusher runs in stone crushing line. It can avoid parts have been burned at the same time and can put on the working efficiency of the cone crusher.
On the other hand, the high temperature will make the lubricating oil swell and reduce the effect of lubrication, so as to increase the friction between cone crusher spare parts, rapidly growing, destruction of cone crusher equipment.To this, be sure to choose those high quality lubricating oil.

The knack of extend the using life of rotary dryer

　　3.When the operation is finished, turn the temperature adjustment knob to 0, in order to reduce improper turn, extend the life of the solenoid valve;
　　4.The cotton filter must be cleaned before using.Or else blocking filter,reducing air flow,producing a slow drying, drying quit phenomenon and wasting energy.

Several ways of softening hard water

when flotation machine is with water or in the ore,it is likely to contain solute mineral salts which impact pharmaceutical and mineral.it is usually carbonates, sulfates, sulfonates, calcium, magnesium, sodium, chloride and silicon compound.
the water become hard water when calcium salt increase.when using Hydroxyl acid to separate will consume a lot of agentia.how to soften hard water?

1.the hardness of carbonate can be eliminated by adding lime.
2.the hardness of non-calcium carbonate can be eliminated by soda.
3.the hardness of Non-magnesium carbonate can not be eliminated only by soda,it must addlime or caustic.

The difference between two screening machine

As far as we know, circular vibrating screen and linear vibrating screen can be screened materials, what is the difference between them?
Circular vibrating screen has high screening efficiency and productivity. Screening accuracy is higher than linear vibrating screen. Now circular vibrating screen used more widely on the market.
Linear vibrating screen belongs to simple screen equipment, mainly used to screen large particle or coarse powder, it is not suitable for screening fine materials, sealing and vibration sieve also have a little different.
Consequently, customers must consider which equipment is most important when customers choose equipments, according to the screen materials and the amount of processing requirements.

Do you know the difference between impact crusher and hammer crusher?

Crusher (also called counterattack crusher, impact crusher, impact crusher) and hammer crusher (hammer broken) are crushing machine which exploit Blunt skills to crush materials ,the main difference between them the following points:
First, hammer crusher is fixedly mounted on the rotor, it can take full advantage of the entire rotor energy when crushing, it is in favour of crushing bulk materials.

Second, there is no grid section in the bottom of the impact crusher, crusher product size is determined by the gap between impact plate and hammer, it is possible to avoid the phenomenon that clogging grid when crushing.

Third, there is a counterattack crusher plates and larger crushing chamber, broken not only by the impact hammer of materials, but the main thing is to use the repeated impact between counter plate material or material.
