Ball Mill is one type of milling machine which is used to mill or grind the materials such as large sized particles either active drug ingredients or excipient and agglomerates. Ball mill consists of horizontal  rotating cylindrical vessel or shell with the length slightly greater than its diameter which is mounted on a metallic frame in such a way that it can be rotated on its longitudinal axis. The axis of the shell or vessel  may be either horizontal or at a small angle to the horizontal.  The cylindrical vessel contains balls that occupy 30-50% of the mill volume. The grinding media is the balls which may be made up of stainless steel. The ball size depends upon the feed and the dia of the mill.

Construction :   Am-colloid mill is driven by a special vertical type highspeed motor, which along with a 5S-housing provides working area of the mill. Circular shaped stator assembly having two different tooth stages, the conical rotor that is directly coupled, and shape of the rotor and stator permits to axially adjust the grinding gap to an accuracy of 0.10 mm. The opening or dosing of this gap is calibrated on a scale. One rotation of the adjusting ring corresponds to a grinding gap of 0.5 mm.   Operation :   In Am-colloid mill the product is subjected to high shearing cuffing, and rubbing forces between two toothed surfaces. The product, while passing down the hopper, inibally gets seized in the preliminary braking drum where  it  is  broken   and  thrown into the  first stator tooth  stage. Due to conical arrangement and the centrifugal effect of the rotor rotating at a speed of 2800 RPM, the material is forced into second tooth stage. The tooth design of the grinding set causes powerful vibrations that subject the particle with high degree of forces. In turn particle reaches the lowest grinding stage. The ground material continuously leaves the mill through the outlet pipe, if required, it can be recirculated.
