Dynamic classifier
DCC Dynamic Classifier Our patented DCC series of dynamic classifiers are so-called air classifiers or turbo classifiers. The wide range of cut points and easy and exact adjustment of the cut point let this type of air classifiers dominate the market of powder processing for almost every product. A further advantage is the “hard classifying characteristic”. That means, by variations of the feed rate the cut point almost does not shift. This performance predestines the dynamic classifier to be used in grinding-classifying-circuits. It has the following advantages: -Airborne principle of design -The cut point does not shift even if the feeding is fluctuated. -Clean cut point without oversize particles -Easy adjustment of cut point -Suitable almost for all kinds of powders classification Technical data: The feed rate is in a range of 0.3t – 20t/h The cut point ranging from D97 3µm-150µm Application: mineral fillers, chemicals, pigments, quartz, abrasives, ceramic, fly ash, metal powder, graphite, mica, foodstuff, pharmacy…etc.

SSC static classifier
The SSC Static Classifier The SSC static classifier is a newly developed classifier with free vortex flow. As its name indicates, there are no rotating parts. Therefore, it is easy to be wear-protected for hard mineral processing. The classifier users find that the high-speed rotors are damaged easily under strong impact and abrasion, consequently, contaminating the products. This static classifier is approved to be the best solution for eliminating contamination. Furthermore, the optimized design of spiral flow and rinsing air guarantee the output of fine products free from oversize particles as well as coarse fraction clean. The SSC static classifiers can achieve a sharpness of cut point nearly as good as much more expansive multi-wheel classifier. The advantages as follows: -This classifier has neither rotor nor motor: low investment -Static classifier has no motor: low running cost - Easy to be protected with ceramic tiles or PU for iron-free production. -Easy maintenance on-site: low maintenance fee. -Sharpness of cut point as good as those of the most expensive multi-wheel classifier. - For fines collection a cyclone is sufficient, filters are not necessary. In the classifying process this kind is often used for taking away the dust from the end product to get clean particles. It is also used to separate the small amount of very big particles from the fines. When it is used for pre-classification it can optimize the main classifying process by rejecting either fines or coarse resulting in high classifying efficiency. Applications: •Suitable for classifying hard minerals, such as silica, quartz, pegmatite, feldspar, granite, ceramics…etc. •Suitable for classifying food stuff or spices particularly those with high content of fat. •Suitable for classification of flaky particles i.e. flaky metal effect pigments, talc, graphite ...etc. •Working in high temperature conditions which classifier with wheels cannot stand. Technical data: The feed rate is in a range of 20kg to 12000kg/h The cut point ranges from D97 5µm-120µm

Multi-wheel classifiers
The Multi-Wheel Classifiers Our IMC Multi-wheel classifier series have been developed especially for ultra-fine products. With the IMC series we extended our program of the DCC series. The multi-wheel classifiers have the principle similar to the dynamic classifier, but the wheels are in horizontal arrangement. As we know, the throughput of the product is related to the surface area of the wheel whereas the fineness of the product related to the speed of the wheels. The main point of its development was to achieve high throughput rate of ultra-fine end products, so a good sharpness, high efficiency and low specific energy consumption with highest output were set as the guideline for this target. We have achieved these criteria by optimizing the dynamics of air flow, the material resistance and the multi-wheel concept. Our IMC multi-wheel classifiers have the following advantages: -High output of ultra-fine products - Sharp cut point without oversize particles -High efficiency and low specific energy consumption -Robust construction for long serving life Technical data: The feed rate is in a range of 1t-50t/h The cut point ranges from D97 4µm -200µm Th Applications: Mineral fillers, ceramic fillers, chemical products, plastic powder, pigments and toner, graphite, mica, metal powder, foodstuff, pharmaceuticals and so on.

universal classifier
Universal Classifier The universal classifier belongs to the category of so-called air classifiers or turbo classifiers. It uses airborne principle to transport the feed material into the classifying chamber where a rotating wheel is installed. This type of classifier makes a wide range of cut points and easy and exact adjustment of the cut point by variation of the classifying wheel speed. Therefore, this type of classifiers dominates the market of powder processing for almost every product. A further advantage is that this type of classifier is characterized with “hard classifying features”. That means, the fluctuation of the feed rate almost does not shift the cut point. This performance predestines this type of classifier to be used with a grinder to form a grinding-classifying-circuit. It has the following advantages: -Airborne principle of design. The feed material transported pneumatically into the classifier chamber -The cut point does not shift even if the feeding is fluctuated. -because of optimal double sealing the product always has a clean cut point without oversize -Easy adjustment of cut point by the speed of the rotor controlled with frequency converter -Suitable almost for classification of all kinds of powders - Easy operation with low maintenance cost.

No wheel classifier
No wheel classifier No wheel classifier means there is no rotor in the classifying chamber. No wheel classifier is also named static classifier. Following free vortex flow principle we have developed such a classifier. With cutting-edge technology we solve the critical problem of classifying silica, pure quartz and many other hard minerals. The feed material is transported pneumatically into the classifying chamber. The mass flow goes along the guide vanes to form a spiral flow where the classification takes place. The rinsing air comes from the bottom enhances the classifying efficiency. The sharpness of cut point of the product from no wheel classifier is comparable to that coming from the much more expensive multi-wheel classifier, which allow it stand out among the many other types of classifiers in dealing with quartz and many other hard minerals. The advantages: -This rotor-less classifier does not need a motor and complicated structure saving investment. -saving a motor means saving running cost. -Easy to use different anti-wearing material for protection. -Easy repairing on-site, no need to send back to factory saving maintenance time and cost. -Multi-functional: suitable for either take away dust from the product to get clean fractions or eliminate small amount of big particles from the product -Used for pre-classification to make the main classification more effective. -Suitable for extreme working conditions, such as high temperature. Application: For hard and abrasive minerals (quartz, pegmatite, feldspar, granite, ceramic material), abrasive products, flaky metal powder, foodstuff with high content of fat, carbon black...etc. Technical data: Processing capacity: 20 kg/hr to 12000 kg/h. Particle size range: D97 5 to 150µm

turbo classifier
The turbo classifiers belong to so-called air classifiers or dynamic classifier. It consists three parts: the classifier chamber at the top with one wheel of vertical arrangement, the secondary air inlet in the middle and the lower part, a cone for feeding and discharging of the reject. Owing to the double sealing there is no oversize particles in the products. Meanwhile, the wide range of cut points are easily and exactly adjusted by the speed of the wheel control with a frequency converter. Therefore this type of air classifiers dominate the market of powder processing for almost every product. A more important advantage is the “hard classifying characteristic”. That means, even though variations of the feed rate occurs the cut point almost does not shift. This performance predestines the turbo classifier to be used in grinding-classifying-circuits. Technical data: The feed rate is in a range of 0.3t – 20t/h The cut point ranging from D97 3µm-150µm Applications: Mineral fillers, chemicals, pigments, paint, toner, silica, ceramic, abrasives, metal powder, foodstuff, pharmaceuticals, fly ash, solid waste...almost all kind dry powders products.
