Product Overview

Highlight Advantages

Due to the lower specific gravity of fly ash compared to other materials, it occupies a much larger volume for the same weight. In response to this characteristic, we have redesigned the next-generation separator for fly ash separation, fully optimizing the separator area and the classifier's grading capability.Internal recycling technology, achieving zero emissions and pollution-free operation, creating green and environmentally friendly enterprises for our customers.

Compared to traditional sifter machines, the fly ash sifter machine boasts the following outstanding advantages:

Compared to traditional sifter machines, T-Sepax is highly efficientFly AshThe three-separation classifier boasts the following outstanding advantages:

T-Sepax High-EfficiencyFly AshThe three-separation sifter employs two-level separation and three-level dispersion, dividing materials into three parts, namely "coarse powder (d>150um), medium-coarse powder (60um<d<150um), and fine powder." It pre-separates the coarse particles from the mixed powder into the coarse powder cone in the first-level grading area. The second-level grading area is the grading zone, where separation is completed within the annular region formed by the guide vanes and the straight-cage rotor. Due to the pre-separation of coarse particles, interference from coarse particles is eliminated, resulting in high grading accuracy and a separation efficiency of over 85%.
2. T-Sepax High-EfficiencyFly ashThe three-separation classifier has a significantly higher yield compared to centrifugal, cyclone, and rotor classifiers of similar dimensions, making it more suitable for large-scale production needs. Its reasonable structure allows for a wide range of changes in classifier air volume, yield, and feed rate without affecting classification efficiency, and its grading performance is extremely stable.
3. The grading principle is excellent. By combining multiple selection powder principles and utilizing aeronautical aerodynamic analysis methods to optimize the entire flow field, the equipment's resistance is significantly reduced, and the selection efficiency is greatly improved, with remarkable energy-saving and consumption reduction. The selection machine rotor is equipped with an inventor-patented vortex rectifier, where the airflow inside the rotor rises relative to the rotor without rotation, resulting in a uniform and stable gas flow field on the surface of the grading ring: the relative error of airflow at any point is <5%. By utilizing the reduced momentum after the airflow enters the rotor, the driving power is saved and wear is minimized.
4. The sifter features stepless speed adjustment. Fine particle adjustment is easy, sensitive, and reliable, with a wide range of adjustment.
5. The selection area and upgrading zone have been re-optimized and redesigned. The T-Sepax high-efficiency three-separation classifier is compact in structure and small in size, suitable for any closed-loop powder grinding system composed of any powder grinding equipment. It is applicable to both open-flow grinding modifications, single closed-loop mills, and double closed-loop mills, particularly for semi-finished and finished powder grinding systems equipped with roller presses.
6. The wear-prone parts of the classifier, such as the撒料盘 (dosing disk),旋风筒 (cyclone tube),蜗牛角 (snail horn),导风叶片 (guide vanes), and impeller, are all made from wear-resistant materials or treated with anti-wear processes, resulting in extremely low wear rates. The classifier's interior lining is made of new manganese plates, effectively extending its service life.
7. The main shaft lower bearing seal employs a new design concept, effectively resolving two major issues: dust entry into the bearing and oil leakage from the lubricant, thereby significantly extending the service life of the lower bearing.
8. During the design of the sifter foundation, the principle of mechanical vibration reduction is adopted to ensure that the resonance frequency of the sifter and the foundation does not approach the inherent frequency of the sifter, thereby overcoming resonance and fundamentally solving the long-standing vibration issue困扰ing users.
9. Both coarse, medium coarse, and fine powder pipes utilize dual-locked air valves, significantly reducing the system's air leakage rate and overcoming the issue of excessive dust generation during the operation of old-style separator machines.

Working Principle

  In operation, the variable-speed motor drives the vertical drive shaft through a transmission device. Materials enter the separator chamber through the feed opening at the top of the classifier. They then fall onto the distribution pan via pipes set between the upper and lower cones of the coarse powder collection cone. As the distribution pan rotates with the vertical drive shaft, the materials are evenly scattered outward due to inertial centrifugal force. The dispersed materials are then subjected to a high-speed airflow through an external blower entering the separator chamber. The heavier coarse particles are propelled towards the inner wall of the separator chamber by the inertial centrifugal force. After collision, they lose kinetic energy and slide down the wall, falling into the coarse powder collection cone. The remaining particles are lifted by the rotating airflow and, as they pass through the area of the large blades, some coarse particles are again thrown towards the inner wall of the separator chamber by the impact of the large blades. After collision, they lose kinetic energy and slide down the wall, ending up in the coarse powder collection cone.
Coarse and fine powders are further elevated by an upward airflow after passing through the large fan blades, continuing to rise and enter the second-class selection area through vertical guide vanes. Under the influence of strong and stable planar vortices formed by the rotating cage-type rotor, the dust-laden airflow causes the coarse powders to lose kinetic energy and be thrown against the vertical guide vanes by centrifugal force, falling into the coarse powder collection cone and then discharged through the coarse powder tube. The fine powders that meet the requirements pass through the cage-type rotor and enter its interior, following the recirculating air into an efficient low-resistance cyclone separator, and then slide into the fine powder collection cone to become finished product.
