ZH series combined powder classifier is a high-performance powder classifier
Brief Introduction: ZH series combined powder classifier is a high-performance powder classifier that integrates coarse powder separation, horizontal vortex powder separation and fine powder separation. It is currently widely used in raw material ring flow grinding systems. The high-concentration dust-containing air from the grinding enters the powder classifier through the lower air duct, and after being rectified by the inner cone, it rises at a reduced speed along the annular channel between the outer cone and the inner cone. The coarse powder in it settles by gravity along the outer cone.
ZH series combined powder concentrator is a high-performance powder concentrator that integrates coarse powder separation, horizontal vortex powder concentrator and fine powder separation. It is currently widely used in raw material ring flow grinding systems. The high-concentration dust-containing air from the grinding enters the powder concentrator through the lower air duct, and after being rectified by the inner cone, it decelerates and rises along the annular channel between the outer cone and the inner cone. The coarse powder in it slides into the coarse powder collecting barrel along the side wall of the outer cone through gravity sedimentation to achieve gravity separation. The air after gravity separation forms a stable horizontal vortex powder separation area between the guide vane and the rotor under the guidance of the guide vane and the rotation of the rotor. The ground material is fed into the powder concentrator from the feed port and evenly spread to the surroundings through the rotating spreading disc of the rotor. Due to the blocking effect of the retaining ring, the material is scattered in the powder selection area between the guide vane and the rotor in a dispersed state. The dust particles moving in the powder selection vortex will be affected by gravity, wind and rotating centrifugal force at the same time, so the dust particles with different initial velocities and different particle sizes will have different movement trajectories. The fine and light particles are sucked into the rotor with the air flow and flow through the air distribution chamber into the cyclone dust collector in four ways. Most of the finished fine powder is separated out, and the air after dust collection is discharged from the exhaust pipe on the cyclone dust collector and enters the next level of dust collection equipment. The coarse and heavy particles fall down, gather into the coarse powder collecting barrel through the inner cone, and return to the mill for re-grinding. Changing the rotor speed can change the initial velocity of the dust particles and the streamline curvature of the vortex in the powder selection area, and also change the direction of the wind force and the magnitude of the centrifugal force on the particles, thereby effectively adjusting the fineness of the finished product.
Technical features:
- Large output and wide working conditions. The powder selection air volume, output and feed volume can vary in a large range without affecting the powder selection efficiency, and the classification performance is stable;
- Compact structure, one machine with multiple functions, integrating coarse powder separation, horizontal vortex powder selection and fine powder separation, with a set of low-resistance and high-efficiency cyclone dust collectors, which greatly reduces the processing pressure and workload of the next-level dust collector, with higher operating rate and lower investment;
- High efficiency and energy saving, aviation aerodynamic optimization design, low equipment resistance and reduced power consumption;
- High-efficiency and low-resistance cyclone dust removal technology, high collection efficiency and low resistance;
- Simple operation, convenient fineness adjustment, and remote control can be realized; wear-resistant parts are treated with anti-wear technology, with low wear and low maintenance cost.
