How many types of ball mill 1. Based on the axial orientation a. Horizontal ball mill. It is the most common type supplied from 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 that 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 very commonly used in industries owing to its capacity limitation and specific structure. Vertical roller mill comes in the form of an erect cylinder rather than a horizontal type like a detachable drum, that is the vertical grinding mill only produced base on custom requirements by vertical ball mill manufacturers. 2. Base on the loading capacity Ball mill manufacturers in China design different ball mill sizes 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. Such as ball mill for mining, ceramic industry, cement grinding. b. Planetary Ball Mills, small ball mill. 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 3080 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. JXSC ball mills are designed for high capacity long service, good quality match Metso ball mill. Grinding media 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 rotat
ion 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 dont 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.
The traditional ultra-finepowder-processing equipment,due to its low production capacity, is unable to meet the requirements of large-scale productionto satisfythe increasinggreat market demand. Combining several decades of powder mill R&D and production experienceand by introducing advanced technology from Taiwan and Germany, Honecheng has designed and developed the HLMX Superfine Vertical Millbased onHLM Vertical Mill. It becomesthe first choice for large-scale production of ultrafine powderby solving the issue of low production capacity of traditionalsuperfine mill.
The HLMX Superfine Vertical Mill, with static and dynamic separator, can produce powder with a fineness ranging from 325mesh(40m)to 2500 mesh(5m). It can be widely used in chemical, metallurgy, non-metallic mining industries forgrindinglimestone,calcite, marble, calcium carbonate, kaolin, barite,bentonite, pyrophyllite etc. HLMX Superfine Vertical Mill iscapable of providing high qulity filers and additives used in the papermaking, segments, plastic, rubber, pigment,printing ink, PVC and so on.
The motor drives the reducer to rotate the millstone, the raw material issent into the center of the millstone from the air lock rotary feeder. Under the effect of centrifugal force, the material moves to the edge of the millstone. Material than be ground by the force of the roller and smashed under extrusion, grinding and cutting. At the same time, air is blew up around the millstone and bring up the ground material. The air will blow the coarse material back to the millstone. The fine powder will be brought to the classifier, and then, the qualified fine powder will flow out the mill and be collected by dust collector, other coarse powder will be brought down to the millstone by the blade of classifier and be ground again. The circulation like this is the overall process of grinding.
When moving together with the materials to the fridge of the grinding plate, due to its weight, the tramp iron cannot be raised by air flow but falls into the lower mill chamber and then is scraped into the slage outlet to be dischargedby the scraping plate. This efficiently ensures the quality of finished powder product.
With scientific & reasonable design and abovementioned unique advantages, HLMX ultra-fine vertical mills are applied widely in metallurgical, chemical and non-metallic industry, for grinding of various materials, such as limestone, gypsum, coal, barite, calcite etc. Itis large-scale equipment breaking through the bottleneck of ultrafine powder processing capacity. It is your best choice for large-scale production of ultrafine powder.
The secondary classifying system includes ultrafine classifier, fan, dust collector, hopper, screw conveyor and pipes. Ultrafine classifier is the core equipment of the whole system. HLMX series ultrafine vertical mill is equipped with the secondary classifier system, which is capable of efficiently separating coarse powder from fine powder to obtain products of various fineness from 800 mesh to 2000 mesh.
The classifying system is capable of selecting fine particles from the materials. The fineness can range from 800 mesh to 2000 mesh. With the secondary classifying system, different particles size can be obtained and it is also rapid to achieve high production stability product of the same particle size.
(1) The grinding curves of the roller shell and liner plate are uniquely designed based on the ultrafine powder pulverization. The material bed can be formed easily so as to increase the grinding efficiency and the ratio of the finished powder product from the primary grinding.
(3) Adopting the principle of muti-rotor classifier, the product fineness can be easily and efficiently adjustedamong the selected fineness range. HLMX series ultrafine vertical mill saves energy by 30%-50% compared to a common type ultrafine mill when producing the powder of the same fineness.
