reduction based on ball mill

reduction based on ball mill

The optimum size reduction in a ball mill depends o the following factors: Feed quantity: Too much feed will produce cushioning effect and too little feed will produce loss of efficiency of the mill. Speed of rotation of the cylinder: At low speed the mass of balls will . ...

  • A specific energy based size reduction model for batch

    A specific energy based size reduction model for batch

    A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function, which calculates the particle breakage index, t 10, according to the size-specific energy, and then calculates the full product size distribution using the t 10-t n relationships and the mass-size balance approach.

    At 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.

    mill. The grinding chamber of the ball mill was pro-vided with a cooling jacket through which coolant was passed to maintain a temperature of 14 C( 1 C). This is done to take care of the rise in temperature as a result of grinding, which may affect cell rupture to some extent. The mill was operated at 1100rpm with treatment time up to 20min.

    Ball mill Wikipedia

    A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either …
