Combined powder classifier

Product Advantages

The ZH series combined powder classifier is a fourth-generation, high-efficiency classifier that utilizes the principle of horizontal eddy currents for polarization. It is a new type of powder classifier developed by our company based on imported foreign technology and combined with domestic production practices.

1. Increased Output, Energy Saving, and Consumption Reduction
   The grinding system's output can be increased by 30-50%, while unit energy consumption can be reduced by 5-20%.

2. Improved Quality, Reduced Costs
   The increased content of particles in the 3-30 μm particle size range helps improve cement strength, increase slag content, and reduce clinker usage.

3. Simple Operation, Convenient and Flexible Fineness Adjustment
   The main motor and lubricating oil station can be remotely controlled. Simply adjusting the main motor speed allows for variable product fineness. The particle size distribution, air volume, and internal temperature can be adjusted arbitrarily.

4. High Processing Capacity
   The residual fine powder in the reground coarse powder is minimal, resulting in a very steep Raum curve and high processing capacity.

Working Principle

The classifier's outlet elbow connects to the dust collector's inlet. Air is drawn into the classifier's vortex housing through the primary and secondary air inlets by the dust collector's fan. Driven by the guide vanes, the rotor's rotation, and the fixed buffer plates, a stable, horizontal, circular vortex is formed between the guide vanes and the rotor. Grinded material is fed into the classifier's inlet and evenly distributed by the rotating spreader. The retaining ring blocks the material, allowing it to fall dispersedly into the classifier between the guide vanes and the rotor. Dust particles moving in the vortex are simultaneously affected by gravity, wind, and centrifugal force. Fine, light particles are drawn into the rotor with the airflow and collected by the dust collector through the air outlet, becoming the finished product. Coarse, heavy particles fall down and are collected in the coarse powder outlet of the lower cone, returning to the mill for further grinding, thus forming a closed-circuit system. Changing the rotor speed effectively adjusts the fineness of the finished product.
