Powder Engineering
The classifier type CCM combines a mechanical impact mill with an integrated dynamic classifier and is used for dry fine and Feist reduction of soft to medium-hard materials, particularly temperature sensitive and difficult to be milled products. The classifier mill type PSM is used when high demands are made regarding Rießelfähigkeit, particle size distribution and grain structure. Due to the exact definition of the upper grain boundary allows a narrow particle size distribution and promoted a certain particle size in the micron range is not exceeded.
Special Features:
• optimized diffuser: optimized internal flow in terms of material circulation and higher grinding capacity
• Leitapparatt interchangeable suitable for various products to increase efficiency
• Sensors for monitoring the process for high reliability and availability
• Complete system with matched components - Classifier, fans and centrifugal separator at an affordable price
Versions:
• dynamic classifier - different heights and different number vo Sichterblätter (diagonally, radially arranged)
• grinding disc - different sizes and materials, different number of Mahlhammer
• Depending on the application, different materials: treated cast iron, steel, stainless steel, special steel, ceramics), surfaces or polished, wear protection.
• Standard - air purge nozzles, sensors for temperature and vibration of stock
Function
The material is pneumatically fed to the mill and uniformly distributed in the grinding zone before entering. In the beating zone, the air flow is set into a turbulent flow. In the fluidized both the direction and the velocity of the particles is changed in an extremely short time. The material is crushed by the impact on the rotating grinding tools and the stationary grinding path. Variation of the rotor speed infinitely variable. Various Mahlbahnprofile.
In the classifier zone, the ground material is supplied to the Leitschaufelt the stator along. Which grain size is transmitted through the dynamic classifier can be determined duch the airflow and the classifier and modified during operation. The coarse particles are returned to the grinding process. The grinding chamber is strömungsoptiemiert and prevents deposits. Sichterspaltspühlung and Wellenlagerungspühlung prevents the ingress and egress of product vo lubricant. Thus, the upper limit of the grain size is guaranteed or Produktkontramination avoided.
The fine particles that have passed through the classifier wheel are extracted and separated by a Zetrufugalabscheider.
