Friedrich Fischer (March 19, 1849 October 2, 1899) from Schweinfurt, Germany is considered the father of the modern ball bearing, having invented the process for milling standard bearings in 1883.. Biography. Fischer designed the ball grinding mill, a machine that allows steel balls to be ground to an absolutely round state in large volumes for the first time.
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.
Ball mill is suitable for grinding various materials with different hardness and humidity. That's because it has two kind of grinding modes, dry process and wet process. Customers can control the capacity and final products' fineness by adjusting the diameter of the ball. The final products can be adjusted between 0.074mm to 0.4mm according to
Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include:
A ball mill, comprising: a sample holder comprised of a plurality of vessels, each vessel having a tubular configuration and a longitudinal axis about which an interior for performing ball grinding is defined;
