The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the
A ball mill works on the principle of impact: 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 horizontal or at a small angle to the horizontal. it is partially filled with balls/ Grinding Media.
Several types of ball mill exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 litres for planetary ball mill, mixer mill or vibration ball mill to several 100 litres for horizontal rolling ball mills.

Ball mills are horizontal cylindrical shaped equipment that finds appliion in grinding hard minerals to the form of fine powder. The grinding operation is achieved here through rotation of cylinder with steel grinding balls/ceramic balls that causes balls to fall back
I see that several have answered based on dry grinding, i.e. Vertical Roller Mill vs. conventional Ball Mill. If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies.
Horizontal ball mill is an efficient tool for fine powder grinding. Ball mill is often used for grinding silica sand. The horizontal ball mill is used to grind many kinds of mine and other materials, or to select the mine. horizontal ball mill is widely used in building material, chemicalindustry, etc.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Hence, milling which might take minutes to accomplish in a SPEX mill could take hours in an attritor or days in a horizontal ball mill. All of these processing routes, however, have very low energy conversion efficiency, in that only a small fraction of the milling energy expended effects microstructural change contributing to the MA process.
Ball mills are horizontal cylindrical shaped equipment that finds appliion in grinding hard minerals to the form of fine powder. The grinding operation is achieved here through rotation of cylinder with steel grinding balls/ceramic balls that causes balls to fall back into cylinder and onto material which requires being grinded.
