Grate Discharge Ball millswith low pulp levels benefit from the full impact of thegrindingmedia acting on the ore particles, as it falls into the shallow pulp. With a deep pulp level thegrindingmedia is cushioned in the pulp, thus losing its energy and reducing its grinding ability.Get Price
The CIW is a SmallBall Millthat’s belt driven, rigid bearing, wet grinding, trunnion orgratedischarge typemillwith friction clutch pulley and welded steel shell. The 7 and 8 foot diametermillsare of flange ring construction with cut gears while all other sizes have cast tooth gears.
Historically,grate discharge ball millswere used to avoid overgrinding and/or slimes generations when using largerball size. At the time, smallerball sizedid not exist and/or more expensive so that was the only way to achieve the grind economically.
Grate linersandball millliner The type ofball millliner known as agrateliner is designed for discharge efficiency. It allows the discharge of ground materials via slots. With the Magotteaux range of alloys and their experience a longer lifetime and optimal grinding can be achieved.
Ball millis a type of grinder machine which uses steelballas 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.
Jun 23, 2020· A reliablemilllining supplier will always consider these factors when offering the best solution for conversion of aball millfrom an overflow to agratedischarge. For suitablemills, Metso is able to provide modelling of themillbefore and after conversion to quantify the process benefits of the conversion, and then design the best ...
Ball mill, also known asball grinding machine, a well-knownore grindingmachine, widely used in the mining, construction, aggregate application. JXSC start theball millbusiness since 1985, supply globally service includes design, manufacturing, installation, and free operation training.
For overflowball mills, the charge should not exceed 45% of themillvolume . Forgratedischargemills, the charge should occupy about 50% of themillvolume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of themill, R, i.e.,

A database of slurry residence time collected from industrialball millswas established and used to investigate the typical range of the volume-based slurry residence time in a normal industrialball milloperation, and to set up an onset point forball milloverfilling warning in the specific energy-basedball millmodel (Shi and Xie, 2016).
Manufacturer of qualityball mills, designs from 3 ft to 7.5 ft in diameter. Overflow andgratedischarge for wet and dry grinding. Pebble and rodmillsavailable.
Here I try to explain howground slurryis discharged from agrate ball mill(or SAG). How it works is, the slurry flows across thegrateas it would a screen panel. On the other side of thegrate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is “pumped” out and discharged.
