1、 Overview

The HWV cyclone mill has an advanced principle and a unique function of adjustable clearance without disassembly. The strong vortex generated in the crushing zone has an amazing crushing effect and good material dispersion. Compared with other crushers, the results show that the material passes through the shortest route from the HWV cyclone rot inlet to the outlet, so its crushing energy consumption is also the lowest. It is a high-end micro powder equipment for processing special materials. Its outstanding technical performance even surpasses similar foreign equipment, and it can fully replace imports. It is currently an ideal environmentally friendly and energy-saving micro powder equipment with good performance, small size, low energy consumption, and low noise.

2、 Purpose and Characteristics

HWV cyclone mill is a universal ultrafine grinder suitable for the crushing of inorganic and organic substances, widely used for ultrafine crushing of low to medium hardness materials in industries such as chemical, dye, plastic, non-metallic minerals, medicine, feed, food, etc. It is suitable for the crushing of polyvinyl alcohol PVC、PE、 Almost all thermosensitive materials such as fibrous materials can be finely ground, and the product particle size can reach as fine as 2-5 μ m.

The characteristics of this machine are as follows:

1. Using a conical rotor and stator, the gap between the rotor and stator can be adjusted by lifting and lowering the upper box (stator) to control product fineness and yield, with an adjustment range of 0-5mm;

2. The rotor is made of special high-strength steel and high hardness wear-resistant parts imported from Europe. The maximum outer speed of the rotor is over 125 meters per second, and it has the characteristics of long service life

3. The box designed with computer-aided design has smoother discharge and lower noise, greatly reducing the wall sticking phenomenon of micro powder when dealing with viscous and cohesive materials

4. Processing large air volume, low temperature rise during crushing, especially suitable for thermoplastic and fiber materials, with uniform product particle size:

5. Optional fan blades can be installed under the rotor to increase air flow:

6. Easy maintenance, operation, and cleaning.

3、 Equipment structure and working principle

This machine is a turbine type ultrafine pulverizer. It consists of a frame, a machine body, a crushing device, a feeding hopper, a transmission device, and a motor. Its internal structure is shown in Figure 1. The complete set of ultrafine grinding unit consists of a host, a classifier, a high-pressure centrifugal fan, a cyclone collector, and an electrical control cabinet.

The main working principle of HWV is as follows:

After the material is added from the top of the upper box, it is quickly crushed by the pre crushing blades on the upper part of the rotor, directed towards the four walls of the stator, and enters the crushing zone composed of the rotor and stator. The maximum airflow generated by the ultra high speed rotation of the rotor is influenced by both the rotating and stationary components inside the machine, as well as the appropriate guidance inside the machine, and is transformed into countless turbulent turns. These numerous air flows in the crushing zone drive the material and accelerate it to the same high speed as the air flow. However, the direction and speed of these materials suddenly change in an instant, which is also the principle of this crusher. The particles of each material collide with each other and complete ideal cracking in high-speed airflow. Only a small portion of particles are refined through the impact surfaces of moving and stationary components inside the machine. During the entire transportation period of material particles in the HWV cyclone mill, they are always surrounded by air flow. Therefore, the heat inevitably generated during the ultrafine grinding process is also carried away by the air flow as the grinding medium. The high flow of air and its rapid turbulence ensure minimal temperature rise. The above high-speed crushing principle makes the HWV cyclone mill without screening device particularly suitable for providing a technically safe and economically beneficial solution to the problems in grinding and drying operations.

To achieve the desired fineness and yield, the height of the gap gasket can be increased or decreased to change the gap between the stator and the stator, thereby controlling its yield and fineness.
