Nanoscale dynamic separation-type grinder

Abstract

The invention relates to a nanoscale grinder, and particularly relates to a nanoscale dynamic separation-type grinder which comprises a grinding cylinder with a grinding chamber molded inside, and a feeding chamber communicated with the grinding chamber; the two ends of the grinding chamber are respectively sealed by end covers; one main shaft passes through the end covers and extends into the grinding chamber; a grinding rotor is disposed in the grinding chamber and is driven to rotate by the main shaft; the main shaft is hollow with an internal cavity forming a discharging chamber; one end of the main shaft is provided with a separator rotating with the main shaft; a separation chamber of the separator is communicated with the discharging chamber. The separator of the invention rotates with the main shaft to allow the grinded materials to be directly discharged from the discharging chamber of the main shaft; not only is the structure simple, and dynamic separation is realized; but also the separator is difficult to be obstructed by the grinded materials as a result of the centrifugal force generated by the rotation of the separator, and thus the grinding efficiency is improved; additionally, the separator is formed by laminating a plurality of separation ring layers, which is convenient for mounting, dismounting and cleaning; meanwhile, the gap of the separator and the diameter of the separation ring can be designed to be smaller, and thus nanoscale grinding is realized easily.

Description

technical field [0001] The invention relates to a grinder, in particular to a dynamic separation grinder capable of achieving nanoscale grinding. Background technique [0002] There are many types of grinding machines, including those used for ultra-fine grinding, such as: sand mill, bead mill, Raymond mill, pile mill, etc.; also include wet grinding machines, such as: ball-disk mill, colloidal Mills, jet mills, ultrasonic mills, agitator mills, drum mills and similar grinding machines. At present, improving the grinding efficiency and grinding product precision and developing the application field of the grinding machine are the research directions of the grinding machine. A traditional grinding machine generally includes a grinding cylinder with a grinding cavity formed inside and a feeding cavity connected to the grinding cavity. The two ends of the grinding cavity are respectively sealed by end covers. The grinding chamber is equipped with a grinding rotor driven by th...

Problems solved by technology

In this traditional discharge method, since the separator is statically fixed on the other end cover installed on the discharge pipe, and is generally made of metal materials, it is easy to cause materials and grinding media to block the separator, thereby reducing the Grinding efficiency; at the same time, the static separator is inconvenient to disassemble and clean
