How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.dry grid ball mill machine. dry type ball mill alibaba Alibaba offers 2979 dry type ball mill products About 90 of these are mine mill 3 are grinding equipment A wide variety of dry type ball mill options are available to you such as ac motor dc motor and stepper motor Get Price. ball mill machine in russia

Advantages of dry ball mill: (1) The dry-type ball mill adopts the grate plate type tailing material discharge, the material discharge is smooth, there is no up sizing phenomenon, the cylinder does not need to be cooled, the service life is long, and the failure rate is low. (2) There are many auxiliary equipment for the dry ball mill.SAG mill: The SAG mill adopts a self-return device to realize the discharge of the mill. Ball mill: There are many types of ball mills, mainly including overflow ball mills and grate ball mills. Rod mill: The rod mill does not use grid plates to discharge ore. There are only two types: overflow type and open-mouth type.

Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.The dry grinding circuit consists of a 18.5 foot diameter x 14.5 foot long Fuller grate-discharge ball mill driven by a 2,500 hp motor and operated in closed circuit with a Fuller O'Sepa air classier to produce a final ground product sized at about 80% passing 105 …

The grate-discharge type of Ball Mill has a grate at the outlet of the shell and causes less excessive grinding, compared to the overflow type. Therefore, generally, it is best suited to grind materials up to the particle sizes ranging from 60 to 100 mesh.Dry ball mill: Some discharge materials are extracted by airflow, and the mill and the wind classification device form a closed circuit. For example, the cement mill adopts self-flow discharge. ... The grate plate of the grid ball mill should be replaced when it is worn to be welded and repaired.

To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power isBall Mills | Industry Grinder for Mineral Processing. 30-01-2018· Ball Mills Capacity From 0.2-90 T/H AdvantagesDesigned for long service life, minimum maintenance, can grind and homogenize mineral ores down to the nano range, large volume of processing capacity Max Feeding size <25mm Discharge size0.075-0.4mm Typesoverflow ball mills, grate discharge ball mills Service 24hrs quotation ...

2. Dry ball mill: Some discharges are drawn by air current, and the mill and wind classification device form a closed circuit. For example, the cement mill adopts self-flow discharge.
