【Working principle of ball mill】 Ball Mill is a type of grinding crusher machine used to grind ores and other materials to 25 mesh or extremely fine powders, mainly used in the mineral processing industry, both in open or closed circuits. The length of the grinder barrel coat is usually 1–1.5 times the shell diameter. The ball mill receives the feed from rod mill, jaw crusher and reduces the product into a controlled final grind and a uniform size. Ball mills gear drive barrel rotate manganese, iron, steel balls or ceramic jars (in lab size mills) with the ore, cause impact, smashing force, thus effect crush the ore materials. Rotational speed, grinding balls filling rate, balls diameter are very important to the grinding efficiency. Ball Mills consists of a large cylinder which slowly rotates around a horizontal axis. The cylinder is partially filled with the material to be ground plus the grinding medium (metal grinding balls). Inside the cylinder, the medium will be lifted to a certain height under the action of centrifugal force and then drop or fall, grinding the ore in between the balls as they interact. Feed material to be ground enters the cylinder via a hopper on one end and after being crushed by the grinding medium is discharged at the other end.

How many types of ball mill
1. Based on the axial orientation
a. Horizontal ball mill. It is the most common type of ball mill supplied and used around the world. After confirming the raw material processed in industry, the horizontal ball mill chosen from a wide range available in the China market.
Although the capacity, specification, and structure may vary from every supplier, they are basically shaped like a cylinder with a drum inside its chamber. As the name implies, it comes in a longer and thinner shape form that vertical ball mills.
The drum is filled with material and grinding media, the grinding media wear out gradually, and the materials are ground and discharged automatically. Most horizontal ball mills have timers that shut down automatically when the material is fully processed.
b. Vertical ball mills are not very commonly used in industries owing to its capacity limitation and specific structure. Vertical mills come in the form of an erect cylinder rather than a horizontal type like a detachable drum, that is only produced base on custom requirements.
2. Base on the loading capacity
Ball mill manufacturers in China designed different product models to meet the customers from various sectors of the public administration, such as colleges and universities, metallurgical institutes, and mines.
a. Industrial ball mills. They are applied in the manufacturing factories, where they need them to grind a huge amount of material into specific particles, and alway interlink with other equipment like feeder, vibrating screen.
b. Planetary Ball Mills. They are intended for usage in the testing laboratory, usually come in the form of vertical structure, has a small chamber and small loading capacity.
Ball mill for sale
In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment. Over a period of many years development, the fine grinding fineness have been reduced many times, and the ball mill machine has become the widest used grinding machine in various applications due to solid structure, and low operation cost.
The ball miller machine is a tumbling mill that uses steel milling balls as the grinding media, applied in either primary grinding or secondary grinding applications. The feed can be dry or wet, as for dry materials process, the shell dustproof to minimize the dust pollution.
Gear drive mill barrel tumbles iron or steel balls with the ore at a speed. Usually, the balls filling rate about 40%, the mill balls size are initially 30–80 cm diameter but gradually wore away as the ore was ground. In general, ball mill grinder can be fed either wet or dry, the ball mill machine is classed by electric power rather than diameter and capacity. JXSC ball mill manufacturer has industrial ball mill and small ball mill for sale, power range 18.5-800KW. During the production process, the ball grinding machine may be called cement mill, limestone ball mill, sand mill, coal mill, pebble mill, rotary ball mill, wet grinding mill, etc.
Grinding balls for mining usually adopt wet grinding ball mills, mostly manganese, steel, lead balls. Ceramic balls for ball mill often seen in the laboratory.
Types of ball mill: wet grinding ball mill, dry grinding ball mill, horizontal ball mill, vibration mill, large ball mill, coal mill, stone mill grinder, tumbling ball mill, etc.
The ball mill barrel is filled with powder and milling media, the powder can reduce the balls falling impact, but if the power too much that may cause balls to stick to the container side. Along with the rotational force, the crushing action mill the power, so, it is essential to ensure that there is enough space for media to tumble effectively.
How does ball mill work
The material fed into the drum through the hopper, motor drive cylinder rotates, causing grinding balls rises and falls follow the drum rotation direction, the grinding media be lifted to a certain height and then fall back into the cylinder and onto the material to be ground.
The rotation speed is a key point related to the ball mill efficiency, rotation speed too great or too small, neither bring good grinding result. Based on experience, the rotation is usually set between 4-20/minute, if the speed too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and don’t fall. In summary, it depends on the mill diameter, the larger the diameter, the slower the rotation (the suitable rotation speed adjusted before delivery).
What is critical speed of ball mill?
The critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell. Ball mill machines usually operates at 65-75% of critical speed.
What is the ball mill price?
There are many factors affects the ball mill cost, for quicker quotations, kindly let me know the following basic information.
(1) Application, what is the grinding material? (2) required capacity, feeding and discharge size (3) dry or wet grinding (4) single machine or complete processing plant, etc.
