Aug 13, 2015 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.
Feb 13, 2017 Grate Discharge Ball Mill This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 higher capacity per volume unit as compared with an Overflow Mill.

Jun 24, 2015 The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied by merely changing the pulp dilution.
Grate Discharge Ball Mill Used in wet and dry grinding in both open and closed circuits, a grate discharge ball mill (sometimes known as a ‘diaphragm discharge mill’) incorporates a slotted discharge diaphragm with lifters at the discharge end of the mill. The diaphragm, or ‘grate’, serves to retain the balls and any coarse material,.

The ideal trajectory for a ball allows the ball to fall . primary ball mill from grate to overflow discharge while. . ing action to the mill charge, and at the discharge end, remove the ground . 78 to 80 critical speed, pulp-lifter efficiencies could fall and affect overall mill.
Of grate pulp lifter design in AG SAG mill discharge. The current understanding from literature lacks knowledge of mill content size distribution and its effect on discharge through the grate at various aperture sizes and radial positions. It also indicates that in.
Mill Charge - an overview ScienceDirect Topics. The efficiency of a ball mill depends on the number of contact points between the balls • There is a limit of ball diameter below which centrifuging of mill charge occurs this limit can only be overcome by a change in the manner of ball movement • In sandmills, the grinding charge is driven by an impeller.
Grinding Ball Mill Discharge Rate. grinding control strategy on the conventional milling. the mill discharge from ball mill 1 will increase with the same water addition to sump 1 the particle size of cyclone 1 overflow will increase this will decrease the ratio and hence the control loop will add water to keep the ratio constant however the amount of slurry reporting as fresh feed to the.
The mill from the grates in the slot between the grates and the head. The oversize falls into a bucket wheel on the discharge end of the trommel, gets picked up as the trommel revolves and falls into the stationary rock box. A water jet then squirts that oversize back into the mill through the conical discharge.
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.

Oct 19, 2016 Grate discharge heads for ball mills are completely assembled in the shop, with grates, clamp bars, pan liners, and center discharge liners in place. Depending upon available handling facilities, the head or shell can be lined separately in a repair bay, or after assembly of the mill proper in the trunnion bearings.

When removing the old liner in the ball mill, you should.
Feb 27, 2019 Ball mills are also classified by the nature of the discharge. They may be simple trunnion overflow mills, operated in open or closed circuit, or grate discharge (low-level discharge) mills. The latter type is fitted with discharge grates between the cylindrical mill body and the discharge trunnion.
If a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.

Mar 08, 2021 Grate discharge ball mill Under the same condition, it has a higher capacity and can save energy than other types of mills It is better to choose a grate discharge ball mill when the required discharge size is in the range of 0.2 to 0.3 mm. Grate discharge ball mill is usually applied in the first grinding system because it can discharge.
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.
Overflow ball mill is a kind of ball grinding mill which works in wet water state. It belongs to a type of wet ball mill and is a very common grinding equipment in the concentrator. Ball grinding mills are classified according to the discharge methods and can be divided into overflow ball mill and grate ball mill.
No auxiliary drive is required to perform maintenance, which is done quickly with minimal heavy lifting due to the simple removal of the grate or discharge head to access the mill internals. Sepro Mill shells are manufactured in one piece to high quality standards and are thermally stress relieved to eliminate localized high stress areas.
Ball Mill Liners. Ball mill is a fine grinder. A horizontal or vertical rotating cylinder is filled partially with the balls of ceramics, small rocks, and balls made from stainless steel. The ball charge of a SAG mill is about 29 to 30 .
Apr 23, 2020 With grate discharge mills – typically SAG, AG and ball mills – the conventional relining process at the discharge end usually involves removing the dischargers and grates, replacing with new lined versions and hammering in large, long bolts through the layers to secure the liner components.
