How a Grate Discharge Ball Mill Works 911 Metallurgist

The pulp lifters have three main functions First they must provide adequate support for the grate wall, secondly they must efficiently discharge the product Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end The grate holds the balls inside the mill but allows the slurry to pass through, and Converting a ball mill from overflow to grate discharge

Peripheral Discharge Ball Mills Theory and Practice 911

Ball Mill Grinding Machines: Working Principle, Types, Parts

Grate Discharge Ball Mills: In this type of mill, the ground materials are discharged through the grate plate, which prevents the grinding media from exiting the mill Grate discharge mills are used for coarse grinding Peripheral Discharge Ball Mills: These mills have peripheral slots or grates around the discharge section, allowing the groundImportant advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function The paper demonstrates the application of this methodology to Optimization of Solids Concentration in Iron Ore Ball Milling

How Many Types of Ball Mill? JXSC Machine

1 Shortcylinder ball mill: The length (L) of the cylinder is less than twice the diameter (D) of the cylinder, that is, the ball mill with L ≤ 2D is a shortcylinder ball mill Singlebin structure ball mill, which is mainly used for coarse grinding or primary grinding, has high efficiency 2 Mediumlong cylinder ball mill, that is L = 3D 3Discharge grates play an important role in determining the performance of autogenous, semiautogenous and grate discharge ball mills The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp liftersSlurry flow in mills: grateonly discharge mechanism (Part1)

Ball Mill Liner Design 911 Metallurgist

For 60 mm (25″) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately 131 D in meters (for D in feet, divide 131 D by 33) Wave height above the liners from 15 to 2 times the liner thickness Rubber liners of the integral molded design follow the cast metal designThe discharge of overflow type ball mill is caused by the pulp itself overrunning the lower edge of the bushing of the hollow shaft neck Generally speaking, due to the forced discharge mode, the grate discharge ball mill has higher production capacity than the overflow ball mill, while its discharge particle size is larger On DifferentTypes of Mostly Used Ball Mill in Grinding Line

Slurry flow in mills: grateonly discharge mechanism (Part1)

Discharge grates play an important role in determining the performance of autogenous, semiautogenous and grate discharge ball mills The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp liftersMill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 106 microns; The Diaphram or Grate Discharge mill keeps coarse particles within the mill AMIT 135: Lesson 7 Ball Mills & Circuits Mining
