ATP Turboplex Ultrafine Classifier

The compact Hosokawa Turboplex ATP Ultrafine Classifier is a universal classic perfectly suited to a wide range of practical applications where ultrafine powder is essential, such as in the cosmetics, toner engineering and additive manufacturing sectors. Available in a range of eight single-wheel or five multi-wheel classifier models, the flexible and robust design of the Turboplex ATP means that extremely tight processing tolerances can be achieved, resulting in the efficient elimination of oversized particles and ultra-high fineness values, even for difficult to process material.

Offering high performance and a number of practical features – including sophisticated technology, stable operation even when feed rates fluctuate, economical operation and customised integration of wear protection materials, such as ceramic and PU, which help to contribute to the longevity of the equipment – the Turboplex ATP can easily be integrated into a flexible Hosokawa Multi-Processing System, which is a particular advantage to customers when developing and refining new products.

The Turboplex ATP range is complemented by the new generation ATP-NG range, offering a new type of classifier wheel, processing capability in the sub-micron fineness range and advantages such as 30-50% lower energy consumption for high yield processing. Conveniently, the standard Turboplex ATP can be upgraded by exchanging its classifying wheel and drive unit to the new ATP-NG wheel.

ATP Turboplex Ultrafine Classifier Specifications

The Turboplex ATP Ultrafine Classifier is available as a bespoke, standalone product and comes in two model ranges: Single-Wheel and Multi-Wheel. In addition, there is the new-generation NG models, which offer more energy-efficient operation with comparable and even better results than the standard Turboplex ATP range.

The entire Turboplex ATP collection is customisable, depending on the material being processed, and can be designed to have features such as wear protection using ceramic and PU linings and tungsten carbide coatings, a ceramic classifying wheel, classifier head that can be hinged open and an enlarged fines discharge. There is also the option to have the classifier pneumatically fed (in-line mode). The Turboplex ATP is available in a range of materials, including stainless-steel or mild steel.

The majority of models are available as a pressure-less design, with the exception of the ATP 750 and ATP 1000, and can be ordered in an explosion/pressure/shock-proof design to 10 bar overpressure.

Standard Turboplex ATP models (non-NG) can easily be upgraded to integrate the new-generation ‘NG-style’ classifier wheel and a new drive unit.

Single-Wheel Turboplex ATP Ultrafine Classifier Range

The Single-Wheel version comes in eight sizes (ATP 100, ATP 200, ATP 315, ATP 400, ATP 500, ATP 630, ATP 750 and ATP 1000), which between them offer different options for scale-up, power, wheel speed, air volume, cut point (d97) and product capacities, which include d97 = 8µm, d97 = 20µm and d97 = 45µm..

Multi-Wheel Turboplex ATP Ultrafine Classifier Range

The Multi-Wheel version, specifically designed to process metal powders, mineral powders, toner, abrasives and wax, is currently available in five model sizes (ATP 100/4, ATP 200/4, ATP 315/3, ATP 315/6 and ATP 500/4) and offers the same options for scale-up, power, wheel speed, air volume, cut point (d97) and product capacities, which include d97 = 8µm, d97 = 20µm and d97 = 45µm.

Turboplex ATP-NG Ultrafine Classifier Range

The Turboplex ATP-NG is particularly suited to sub-micron processing requiring a high yield, such as for talc and limestone filler, so is perfect for fineness values that were previously out of reach for production-scale systems. The ATP-NG is also ideal for a coarse end product with a steep particle size distribution. Currently available in a range of eight model sizes (ATP-NG 315, ATP-NG 500, ATP-NG 630, ATP-NG 750, ATP-NG 315/3, ATP-NG 315/6, ATP-NG 500/3, ATP-NG 500/4 and ATP-NG 630/4), this range offers a product capacity of between d97 = 4µm and d97 = 10µm, depending on the model chosen.

The Turboplex ATP Ultrafine Classifier range is intended for the classification of superfine powders with a fineness of d97 = 5 to 10µm, while the new generation NG model can achieve fineness levels of d97 = 2µm (d50 = 0.3µm). Applications include mineral powders, printer toner, pharmaceuticals and talc fillers.

The Hosokawa Turboplex ATP Ultrafine Classifier is an adaptable, piece of processing equipment suitable for universal classification applications where ultrafine powders are required. Available in two model ranges, the Turboplex ATP is integrated with either a single or multi-wheel classifier and is designed depending on the specific nature of the material to be processed and the results that are required.

Classifying air enters the Turboplex ATP and flows in a centripetal direction through the classifying wheel. During the operation, the classifying wheel extracts fines from the feed material through centrifugal force, then transports the ultrafine material to the fines discharge. The remaining coarse material, which has been rejected by the classifying wheel, gravitates downward and out through the course discharge. Before exiting the classifier, the course material is thoroughly and intensively rinsed by air to remove any remaining ultrafine material, resulting in extremely clean course materials.

The product is either gravity-fed through a rotary valve or drawn into the classifying air, in the case of an air-flow classifier model. The fineness of the product is determined by adjusting the classifier wheel speed using a frequency converter. Because the classifying wheel is horizontally arranged, even difficult-to-process and extremely abrasive materials can be processed without difficulty.

For multi-wheel Turboplex ATP models, several classifying wheels of the same diameter are integrated and driven independently at a common speed made possible by a frequency converter. Advantages include superfine end products and high throughput rates from one classifier instead of multiple versions, one metering unit, one exit point for course material and one outlet duct for the fines, enabling variable adjustment of the air flow through the classifier.

Where classification to ultrafine levels is required, the amount of energy required by the standard Turboplex ATP increases. The new generation Turboplex ATP-NG offers a new-style classifier which requires 30-50% less energy to achieve comparable and even finer results and classification down to d50 = 0.3µm.

The Turboplex ATP Ultrafine Classifier is available as a tailor-made standalone product, but the multi-wheel versions can also be integrated into a Hosokawa-designed processing system, which might also include equipment such as a Fine Impact Mill UPZ, blower and product tanks for the course and fine materials. This classifier is also integrated into an AWM Table Roller Mill and is used to assist with the comminution of brittle, yet elastic mineral materials that require fineness values of between 10µm and 100µm.

The Hosokawa Multi-Processing System

For laboratory, pilot-scale and R&D purposes, the Hosokawa Turboplex ATP may also be integrated into a Multi-Processing System suitable for CIP procedures, which also combines a Hosokawa Spiral Jet Mill 100 AS, AFG 100 Fluidised Bed Opposed Jet Mill, Fine Impact Mill with 50 ZPS Classifier and Fine Impact Mill 100 UPZ.

Ideal for producing product samples for testing, the systems offer a very flexible and reliable way of maintaining reproducibility and defining parameters for scale-up to production-scale process milling and classification equipment and systems.

The beauty of the Hosokawa Multi-Processing System is its simple concept, which integrates a series of processing components that are common to each of the mill modules available in the multi-processing system and scaled up versions. Each mill module offers a different range of features, adapting to material differences such as Mohs’ hardness, high density materials and cohesive products. The module is chosen depending on the fineness value required, providing processed material with steep particle size distributions, free of oversized particles and contamination-free.

The different grinding modules can easily be exchanged within a few minutes and can be chosen depending on the nature of the raw material and fineness results required.
