Fly Ash Classifier: Working Principle and Features of Ultra-Fine Classifier

Fly ashSifterUltra-Fine Sifter Working Principle and Features

The ultra-fine sifter equipment allows the material to enter from the feed hopper, where it is divided into two sections by the distributor. One section enters the high-speed rotating impeller through the center, where it is rapidly accelerated to hundreds of times the acceleration due to gravity. It is then ejected at a speed of 60-70 meters per second through three evenly distributed channels in the impeller. It first impacts and crushes the other section that has fallen from around the distributor, then together they strike the material-lining in the vortex cavity. The material is反弹 back, sloping upwards to the top of the vortex chamber, where it changes its direction, deviating downwards. The material emitted from the impeller channels forms a continuous curtain of material.

This material is subjected to multiple impacts, abrasion, and grinding within the vortex crushing chamber. The crushed material is discharged through the lower discharge outlet. Throughout the crushing process, the materials self-impact and break down without direct contact with metal parts, instead, they collide and rub against the material lining, reducing angular contamination and extending the mechanical wear time. The clever internal airflow in the vortex chamber recirculates, eliminating dust pollution.

Material falls into the feed hopper and, after entering the high-speed rotating rotor, is fully accelerated and ejected through the nozzle. It first collides with a portion of the material that has been反弹 and falls freely, then together they strike the vortex material lining (or impact block) inside the nearby vortex chamber. The material is first反弹 to the top of the crushing chamber and then deflects downward, forming a continuous curtain of material as it collides with material emitted from the impeller channel. Finally, it is discharged through the lower discharge opening.

Ultra-fine Sifter Machine Features:

Simple and fair structure, self-impact crushing, ultra-low operating costs;

2. Unique bearing installation and enhanced predecessor spindle design contribute to the machine's characteristics of heavy load capacity and high-speed rotation.

3. Features fine and coarse grinding capabilities;

High-reliability and secure safety devices ensure equipment and personal safety.

5. Smooth operation, low noise, energy-efficient, and high crushing efficiency

6. Affected by the moisture content of the material minimally; moisture content can reach approximately 8%.

7. Low wear and tear on consumables; all are made with high-quality, wear-resistant materials from home and abroad, ensuring long service life. A small number of highly wear-resistant parts are crafted from ultra-hard materials, featuring compact size, light weight, and ease of replacement.

8. The internal airflow in the eddy current cavity recirculates, resulting in minimal dust pollution.

9. The material inside the impeller and vortex crushing cavity significantly reduces wear and maintenance workload. During the production process, the stone material forms a protective layer, ensuring the body remains unworn and durable.

10. Variety of installation methods available, including portable installations.

11. The product is cubic in shape, with high stacking density and minimal iron contamination. It can be used for stone shaping machine ultra-fine powder mill fault and troubleshooting methods.
