High-speed rotary grinder of the classification, characteristics and application
Summary : High-speed rotary Grinder Classification, expertise, application and recent development of new parts. Process and then use the opportunity to introduce the use of several options and techniques.
Micro- Grinder Can be divided into roll-type, high-speed rotary type, media type, air flow, the friction shear etc.. Among them, tell the rotary grinder is mainly used an impact speed of the rotor rotation, shear, friction and achieve the micronized particles. This form of crushed
was hammering the first type, is a long history of typical mill. However, in recent years, research from different angles, and gradually developed a number of new models. Especially for new materials, has developed many of the more high-performance, more efficient mill. For example: as a static copy of the imaging powder, in order to achieve this color chart to Oh's Precision grinding in the past mostly by air mill, but has recently developed a new structure of high-speed rotary mechanical mill, can be achieved low consumption, high efficiency micro-pulverization.

1 classification, characteristics and application technology Pink high-speed rotary grinder
There are many ways. According to the shape and structure can be divided into Hammer, rotary, axial flow, ring form. Also, according to theory can smash smash into the impact and friction type (compression, shear) type two categories.
1.1 Hammer Hammer is turning to install the rotor fixed or swing type hammer or blade. As a hierarchical institution, with screen to learn more broken 100 m of coarse particles of crushed.
His rotor, generally stirrup-shaped swing installation file for peripheral speed of up to 100m / s high-speed rotation, it also has a high crushing capacity.
1.2 Turntable Rotary mill or a turbine, such as pin mill. The turntable fixed blade with pin or the impact of components, the direction of a diameter greater than axial devices. This form of mill generally greater than the Hammer Week speed. It may be more fine crushing. As a classifier, in addition to using screen but also by the wind section was even smaller classifier. In addition, in order to make a greater impact when the relative velocity, have been designed using two reverse rotation of the rotating disc structure micronization.
AM this is a common micro-mill models. It is mainly crushed by the shock room and room air classification of two parts. Shattered by the crushing chamber with a circular canal rotor and stator form. Number of rotor disk is fitted with comfortable range of hammer, the peripheral speed up to 100m / s and even higher. Grade room of the shunt ring and pose ns. Crushing and grading by their own motor drive, adjustable speed due to the contents of air classifier, and thus acquire the appropriate particle size distribution of the products. After the meal by grade, returned to smash a room smash. AM into the wind mill is characterized by large, can inhibit the temperature rise, ideal for a variety of powder coatings, resin raw materials, and thermal crushing the weak. Wide scope of its application.
Recently on this machine a new development. By improving the impact of rotor components, increase the probability of collision during milling material, thus more than double crush capacity. In addition, to meet the needs of the user and easy to clean, this machine also uses open-type structure, so that an easy-clean models.
1.3 Axial Axial mill during milling side of the material in the rotary, axial movement to smash the side to do. In order to control product particle size, the impact of components and hierarchical structure to improve, to achieve speed and air flow adjustments.
Crush room in the two exit installation Canon different rings for size control. In addition, this device, not crush the remnants of a certain size, spiral nozzle through the discharge.
