Closed spiral separator drive spiral separator and bearing closed in the box in the shell, lubrication condition is good, the tooth and not easy to wear, the spiral separator speed can be improved, but its structure is complex, the ball mill, the rotary kiln, dryer, into a ball dish, hoist, belt conveyor, the screw machine,magnetic drum separator rom watts of fan reducer, spiral separator box that is for this kind of application.
The ore in the grinding cylinder of the ball mill machine goes through certain crushing and milling.Finished products that meet the requirement will be taken out by the airflow, which is drawn out to the outside of the barrel.

Before the installment of the ball mill, the workers should examine and check carefully the relative position relations between the base and the adjacent buildings and structures and the adjacent machine sets and make sure the their distances are conformed to the stipulations on the design drawing.There are many methods in the examination process, for example, measure with the measuring apparatus from a certain fiducial point or measure using bracing wire.All these methods are used in order to find out exactly the mutual position relations between them and figure out precisely their main sizes, for example, make sure the horizontal distance, depth of parallelism and verticality, levelness and relative altitude difference of the axis of the ball mill, the gear axis of the reduction box and the axis of the motor and what is more, in order to make sure whether the position and dimension of the obligate hole of the foundation bolt are conformed to the requirement of the design paper and the actual production conditions and whether the actual size of the screw hole on the bottom of the ball mill are all the same.After the check and examination work is confirmed and the workers can maker sure that various kinds of parameters are exact without error, then they can proceed to the installment work after figuring out the positions and sizes.

A sag mill (semi auto-genous grinding) uses steel balls along with large rocks along with grinding.A rotating drum in a sag mill acts to throw the large rocks and the steel balls in a contracting motion and this results in breakage of the large rocks on impact and it leads to compressive grinding of fine particles.This is characterized by a large diameter and short length used sag mills are mainly used for grinding of gold, platinum, copper, lead, zinc and silver.There are hammer mills which are different from ball mills and rod mills which mainly help in shredding mining ore rather than grind it.
Rod grinding mill.Rod milling within the size range utilized is more efficient than ball milling because the specified method is obtained better value per ton.
Because of the enduring economic status of gold, gold ore mining and refining has been hot for centuries.As the main equipment in gold ore processing and refining, gold ore ball mill has always been the investors' favorite selection.
3.This ore grinder mill machine could be used as the pre-grinding equipment before ball mill so as to increase ball mill efficiency by 50%.
Ball mill noise is mainly mechanical noise caused by the collision between the metal ball in the drum and the cylinder wall liner and the processed material.The intensity of the ball mill noise is related to the diameter and speed of the ball mill, as well as the nature and blockiness of the material.Ball mill noise is basically steady-state noise, with a wide frequency band, and low, medium, and high-frequency components have high sound energy.The larger the diameter, the stronger the low-frequency component.

Aside from common ball mills there is a second type of ball mill called planetary ball mill.Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes.A used ball mills consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel.The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1 or else).The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called coriolis forces.The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies.The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.
