Nano vibration ball mill

A vibratory grinder is a powder-making device. It utilizes the high-frequency vibration of a cylindrical drum to cause the grinding media within the drum to impact the material through inertial force. The grinding media are typically round steel bars with a diameter of φ16-φ36mm. These steel bars undergo carburizing and quenching treatment to achieve a hardness of HRC55 or higher. A larger diameter is used when the feed particle size is >15mm, and a smaller diameter is used when the feed particle size is <15mm. Two or more specifications of steel bars (or steel balls) are used in combination. During operation, the motor drives the shaft of the vibrator, which contains an eccentric counterweight, to rotate via a flexible coupling and a universal coupling. This causes the drum to vibrate, and the grinding media and material inside the drum tumble and impact, resulting in the material being pulverized in a short time.

Structural Forms

1. By number of cylinders: Single-cylinder mill, double-cylinder mill, triple-cylinder mill. Double-cylinder mills are the most widely used.

2. By type of grinding media: Vibratory rod mill, vibratory ball mill.

3. By inlet/outlet type: Single-inlet single-outlet, double-inlet double-outlet, double-inlet four-outlet, and many other types.

4. By structural layout: Vertical, horizontal.

Applications

This type of small-to-medium-sized non-explosive material grinding equipment is mainly used in the processing of fine and ultrafine powders in industries such as metallurgy, mining, building materials, chemicals, refractory materials, abrasives, graphite, glass, and ceramics. It is widely used in the ultrafine processing of raw materials in the production of chemical dyes, special ceramics, powder metallurgy, and advanced refractory materials. In recent years, this series of nano-vibratory mills has become known as the grinding equipment for calcined magnesium in the metal industry.
