WhatsAppGet PriceGet A QuoteBall Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
WhatsAppGet PriceGet A QuoteAt low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.
WhatsAppGet PriceGet A QuoteBall mills are usually designed with a maximum reduction factor/ratio of 60:1 although it is possible to achieve reduction ratios of up to 70:1. The electric drive for a ball mill should be able to handle loads where the ball mill is charged by up to 45% with balls.

The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications.
WhatsAppGet PriceGet A QuoteIn general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.

Used for paint pigments, pyrotechnics, ceramics, mineral dressing processes, and more, ball mills help us create many of the products we rely on every single day.
WhatsAppGet PriceGet A QuoteThe balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for
WhatsAppGet PriceGet A QuoteIf a ball mill contained only coarse particles, then 100% of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.

WhatsAppGet PriceGet A QuoteIntroduction: ‘Ball milling is a method used to break down the solids to smaller sizes or into a powder. A ball mill is a type of grinder which consists of a cylinder. It is used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. The cylinder rotates around a horizontal axis.
