What is the disadvantage of ball mill? Disadvantages of Ball Mills 1. Contamination of product may occur as a result of wear and tear which occurs principally from the balls and partially from the casing. 2. High machine noise level especially if the hollow cylinder is made of metal, but much less if rubber is used.

WhatsApp: +86 18838072829Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages:
WhatsApp: +86 18838072829Disadvantages: Lower Capacity. The overflow ball mills discharging speed is lower than that of grid ball mills. As a consequence, the capacity of the former is smaller than that of the latter ...
WhatsApp: +86 18838072829Advantages It produces very fine powder It is suitable for both wet and dry grinding Since it is a close system, toxic substances can be ground Sterility is achieved due to closed cylinder The milling process can be done in an inert atmosphere if the oxygen sensitive substances are to be milled. Disadvantages It is a very noisy machine
WhatsApp: +86 18838072829Mechanical method: In this method, the substance is applied with mechanical force using grinding equipment like ball mill, hammer mill, cutter mill etc. Generally, milling or dry grinding is done for the production of tablets and capsule. Wet grinding is used for the production of suspensions, emulsions and ointments. ... Disadvantages of size ...
WhatsApp: +86 18838072829Ball mills consist of hollow cylinders suspended on shafts and rotating about horizontal axes. Metal, porcelain, or rubber can be used to make the cylinder. A ball or pebble is placed within the cylinder. The cylinder's volume is occupied by balls to the extent of 30 to 50%. Depending on the feed size and the cylinder diameter, the diameter of ...
WhatsApp: +86 18838072829The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
WhatsApp: +86 18838072829However, there are some real limitations of ball mill. As we can see, this kind machine's body is in huge volume. In addition, the strong vibration and loud noise demand comparatively highlystable body foundation. Its uncomplicated working process to a certain degree cannot guarantee low energy consumption with high efficiency. Another ...
WhatsApp: +86 18838072829A Ball Mill is used to grind the materials to get a course or fine powder. Ball mill is also known as the tumbling mill and pebble mill. ... Disadvantage: It is a slow process; Produced strong vibration and sound and less in case of rubber ball usage. Can not reduce soft, tacky, and fibers materials ...
WhatsApp: +86 18838072829The mill consists of a hollow cylinder fixed on a metallic frame in such a way that it can rotate around its horizontal axis. The cylinder contains metallic balls occupying around 30 to 50% of total capacity. The balls are usually made up of rubber, porcelain or metal. The metallic balls are coated with chrome.
WhatsApp: +86 18838072829Fine grinding in traditional ball mills has not been utilised in the past due to the following perceived disadvantages: •. The mill speed has to be lower than the centrifugal speed of the mill otherwise the whole charge will rotate with the mill body and no grinding will occur. This speed limit fixes the maximum electrical power the mill can ...

WhatsApp: +86 18838072829Hammer mill is easy to set up (install), dismantle, and clean up. Scaleup problems are minimum provided the same type of mill is used. Various types of feedstock can be handled using a screen of different sizes. Hammer mill occupies a small space. It is versatile,, speed and screen can be changed rapidly.
WhatsApp: +86 18838072829Introduction Ball milling is generally known as a method to mix, blend, shape and reduce particle sizes. It can also be used as a mechanical synthesis method to produce materials that are milled to extremely fine powders. Several factors, like milling temperature, type of mill, milling speed etc. need to be considered when using ball milling as a synthesis method.
WhatsApp: +86 18838072829However, they also have some disadvantages, such as high energy consumption and the need for a high degree of maintenance to keep them operating efficiently. II. Ball Mills Ball mills are a type of tumbling mill that is widely used in various applications, including mineral processing, cement production, and pharmaceuticals.
WhatsApp: +86 18838072829Ball mill is the key equipment for recrushing the materials after they are primarily crushed. Ball mill is widely used for the dry type or wet type grinding of all kinds of ores and other grind ...
WhatsApp: +86 18838072829The Bond Index conforming ball charge consists of: 43 x " balls. 67 x " balls. 10 x 1" balls. 71 x " balls. 94 x " balls. The optimum number of grinding balls is 285. However, the ball diameters vary due to wear. Therefore, the total ball number should be adjusted from time to time to ensure a total mass of grams.
WhatsApp: +86 18838072829In attritor ball mills, the ball velocities can be lower than in the previous types, leading to frictional dynamics in which shear forces are also important . All these instruments deliver different amounts of mechanical energy per time unit, and they can be operated under slightly different experimental conditions, further varying the overall ...
