WORK PRINCIPLE. ball mill could wet grind and dry grind many kinds of minerals and grindable material, according to different ore discharge methods, there are grid type and overflow type ball mill. High manganese steel plate is more wear-resisting and it has longer service life.
A mill is required to grind 250 tph of limestone from an 80% passing size of 10 mm to 100 μm in a closed-circuit wet overflow discharge ball mill. Calculate the mill size required to handle the required throughput. Step 1. From Appendix B.1, the Bond Work index of limestone is 11.25 kWh/t.
Wet Ball Mill 100 – 20000 litres. Ball mills ( wet or dry processes) for intermittent grinding of hard materials and batches in different branches of the ceramic and chemical industry. To ensure iron-free grinding these mills are lined with steatite, Al2O3 or Polyurethane.
Discharge of minerals by spiral classifier in the classification of qualified products, grit feeder to go back through the joint wet grinding ball mill to continue . Feeder evenly continuous feed , ore feeder through the joint into the wet ball mill continuous and uniform , steady flow of material to be ground from the ball mill discharge.
(24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. Mill speed: 35.2 rpm (65 percent of critical speed) Length of time of test: 363 seconds Average torque reading: 1,056 in-lbs Mill HP = (1,056 in-lbs / 12 in./ft) x (35.2 rpm
What are the Differences Between Dry and Wet Type Ball Mill,Aug 21 2020 · The feeder feeds material continuously and evenly the ground material will be continuously discharged from the ball mill The wet ball mill can be divided into three types according to the motion characteristics a simple swing type wet ball mill a complex swing type wet ball mill and a hybrid swing type wet ball mill

A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances. The energy balance relies on temperature and mass flow data. The key model parameters to be measured are mill temperature in the feed and discharge streams, mill power draw and the mass flow rate in the feed stream. Manipulated variables are

Feeder evenly continuous feed , ore feeder through the joint into the wet ball mill continuous and uniform , steady flow of material to be ground from the ball mill discharge.
The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions. Mathematical descriptions of the method to estimate the
Ball mill is one of the most variable and effective grinding machines which is mainly applied for further grinding the crushed materials. Compared with other grinding mills, the variety of grinding modes, available grinding tool materials, and flexible production capacity make ball mill grinders the perfect match for a vast range of applications, such as cement industry, new building material

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. The discharge trunnion can be furnished with trommel screen.

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. Unlike the grate ball mill
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.
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.
