The ball grinding mill machine usually coordinates with other rock crusher machines, like jaw crushers, and cone crushers, to reduce the ore particle into fine and superfine sizes. Ball mill grinding tasks can be done under dry or wet conditions. Get to know more details about rock crushers, and ore grinders, contact us!

Ball Mill Parts】 Feed, discharge, barrel, gear, motor, reducer, bearing, bearing seat, frame, liner plate, steel ball, etc. Contact our overseas office for buying ball mill components, wear parts, and your mine site visits.
Ball Mill Working Principle】 High energy ball milling is a type of powder grinding mill 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. Ball milling is a grinding method that reduces the product into a controlled final grind and a uniform size, usually, manganese, iron, steel balls, or ceramic are used in the collision container. The ball milling process is prepared by rod mill, sag mill (autogenous / semi-autogenous grinding mill), jaw crusher, cone crusher, and other single or multistage crushing and screening.
Ball Mill Manufacturer】 With more than 35 years of experience in grinding balls mill technology, JXSC design and produce heavy-duty scientific ball mill with long life minimum maintenance among industrial use, laboratory use. Besides, portable ball mills are designed for the mobile mineral processing plant. How much the ball mill, and how much invest a crushing plant? contact us today!

How Many Types of Ball Mills?
1. Based on the axial orientation
A. Horizontal ball mill. It is the most common type supplied by ball mill manufacturers in China.
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 than vertical ball mills. Most horizontal ball mills have timers that shut down automatically when the material is fully processed.
B. Vertical ball mills are not commonly used in industries due to their capacity limitation and specific structure. A vertical roller mill comes in the form of an erect cylinder rather than a horizontal type like a detachable drum. The vertical grinding mill is only produced based on custom requirements by vertical ball mill manufacturers.
2. Based on the loading capacity
Ball mill manufacturers in China design different ball mill sizes to meet customers from various public administration sectors, such as colleges and universities, metallurgical institutes, and mines.
A. Industrial ball mills. They are applied in manufacturing factories, where they need to grind a huge amount of material into specific particles, and always interlink with equipment like feeders, and vibrating screens, such as ball mills for mining, ceramic industry, and cement grinding.
B. Planetary Ball Mills, small ball mill. They are intended for usage in the testing laboratory, usually come in the form of a vertical structure, have a small chamber, and have a small loading capacity.

Ball Mill for Sale
In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, and froth flotation, the working principle is to prepare fine-sized ores by crushing and grinding often with rock crushers, rod mills, and ball mills for the subsequent treatment. Over a period of many years of development, the fine grinding fineness has been reduced many times, and the ball mill machine has become the widest-used grinding machine in various applications due to its 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 primary or secondary grinding applications. The feed can be dry or wet, as the shell is dustproof for the dry materials process to minimize dust pollution.
Gear drive mill barrel tumbles iron or steel balls with the ore at a speed. Usually, the ball-filling rate is about 40%. The mill balls’ size is initially 30–80 cm in diameter but gradually wears away as the ore is ground. In general, the 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 production, the ball grinding machine may be called a cement mill, limestone ball mill, sand mill, coal mill, pebble mill, rotary ball mill, wet grinding mill, etc.
JXSC ball mills are designed for high capacity long service, and good quality matches Metso ball mills.

Grinding Media
Grinding balls for mining usually adopt wet grinding ball mills, mostly manganese, steel, and lead balls. Ceramic balls for ball mills are often seen in the laboratory.
Types of ball mills: 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 ball’s falling impact, but if the power is 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 enough space for media to tumble effectively.

How Does Ball Mill Work?
The material is fed into the drum through the hopper, motor drive cylinder rotates, causing grinding balls to rise and fall following the drum rotation direction. The grinding media is lifted to a certain height and then falls 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 is too great or too small, and neither brings a good grinding result. Based on experience, the rotation is usually set between 4-20/minute. If the speed is 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 The Critical Speed of The 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 operate at 65-75% of critical speed.
