LHP Multi-grade Classifier

The LHP Multi-grade Classifier is composed by several self-diffluent classifiers, which is mainly used in the production of narrow particle size distribution, such as abrasive, superhard materials, metal powders, non-ferrous metal powders, battery materials, light (reflective) materials, coating materials, insulation materials, carbon powders, silica gel, foaming agent, etc. Unique ladder flow structure design, the performance is unapproachable, the technical level is far ahead in the domestic and international similar products.

LHP type multi-classifier is a series of multiple LHB type classifiers connected in series to form a closed circuit system, which can divide powder into several granularity products at the same time.
The material enters the self-diversion classification zone for the first classification from the feed system. Most of the coarse particles are separated. A small amount of coarse particles are carried by the fine powder and the secondary air is carried into the turbine classification zone by the ascending airflow. The fine powder enters the collector through the classification wheel, the coarse particles are discharged from the discharge valve of the classifier.



The classifier is a new ultra-micro classifier independently developed by our company. It is a perfect combination of self-split inertial classification technology and centrifugal classification technology. The core technology has reached the advanced level in the world today, and its technical performance is a qualitative leap forward than that of turbo classifier .
1. It is used to produce products with narrow particle size distribution requirements, and the upper and lower limits of finished product particle size are strictly controlled.
2. It produce several granularity grade products at same time, one multi-classifier can replace several single-stage classifiers.
3. Low energy consumption: the same processing capacity, energy consumption is reduced by 50% compared with other horizontal and vertical classifiers.
4. High efficiency: With the same processing capacity, the classification efficiency is increased by 50% compared with other horizontal and vertical classifiers.
5. High precision: high classification fineness, completely eliminate oversize particles and sieve residues in the product.
6. Low speed: the same classification particle size, the speed of the classification wheel is reduced by 50% compared with other horizontal and vertical classifiers. When producing powders with Mohs hardness <5, the classifying wheel has no wear; when producing powders with Mohs hardness ≥7, the service life of the classifying wheel is increased by 5 to 8 times compared with other horizontal and vertical types.
7. Full structure: According to different special requirements, a dedicated hierarchical structure can be configured.
8. It can form a closed or open circuit system with ball mills, Raymond mills, impact mills, airflow mills and other grinding equipment.
9. Negative pressure production, no dust pollution, excellent environment.
10. High automatic, strong stability and easy operation.
