Classifier - Import export

The PAS integrated classifier mill is designed to treat a wide variety of products obtaining a particle size of 99% down to 10µm. The PAS is equipped with a grinding plate and integrated classifier that are driven independently by frequency variation motors. Different versions of the PAS are available, giving a wide flexibility in terms of installation and usage. The variety of grinding tools (plates, liners) when associated with a variable speed static and dynamic classifier guarantees a high quality ultrafine finished product for all applications. The PAS can be equipped with our latest patented technologies SEALMAX© new generation classifier, OPTICYCLE© internal ultrafine recycling system.

The MICRODYN is an abbreviation of the words "MICROclassificateur DYNamique". It is composed of one or several variable speed classification rotors, clean air for rinsing and a waste discharge spout. It is particularly effective for the production of very fine powder from a pulverulent produced by an existing grinding process. It is fitted as standard on the PAS Integrated Classifier mills. The fine particles are transported by the pneumatic circuit towards a finished product collector (cyclone or filter for finer products). The oversized particles are evacuated out of the circuit along a skirt or through a rotary valve.

The SMA is a mechanical airclassifier, autonomous equipment designed to separate a material of intermediate fineness (0 to 5 mm for instance) or a ground product (0 to 1 mm or less) into two fractions of different finenesses one fine fraction (particles from 0 to 40 microns up to 500 microns); one coarse fraction (from 40 microns to 5 mm for instance). This air classifier can be used either as a classifier operating in an open circuit (for extraction of natural raw material like sand for instance) or in a closed milling circuit, to control the fineness of ground product or to "preclassify" when the classifier is placed after the air separator and grinding oversize only.

The SHR is the latest generation of our High Efficiency Dynamic Classifier. Our new SHR is used to classify a large range of particles (d98 from 5 to 1000 microns) at a high level of efficiency. This Classifier which is fed by gravity discharge is particularly suited to high throughput rates up to several hundred tons per hour. The SHR is fitted with our patented air seal SEALMAX which allows a very sharp top cut even for very high fineness. The SHR is able to reach high fineness up to D98 5 microns depending on the product. It has been designed to be coupled with every type of mill. In order to improve the yield of this type of separator, POITTEMILL has designed an original system of air purge that extends the time the product remains in the selection zone. With this solution, the recycling becomes external and the recycling of the installation is now meazurable and visible. We can optimize all the classification process

The DYNAIR is a Double Whizzer Dynamic classifier. This type of separator is usually installed on Pendulum Roller mills but can be used in a pneumatic circuit, alone or combined with a Pulverizer or Ball mill with the possibility of recycling the oversized particles
