Powder Processing Equipment & Systems The cutting edge in economical size reduction TYPICAL WORKING VALUES FOR NIBBLER RANGE Size reduction systems from 500mm to 150 micron

Gericke Nibblers; Simple, Flexible and Comprehensive Size Reduction. The most effective method of particle size reduction has been a major consideration for solids handling processors for many years and in the past has traditionally involved the use of large scale equipment with high capital cost and energy requirements. Today, Gericke Nibblers provide the ideal alternative. Cost effective, highly efficient solutions for coarse and fine size reduction and also the de- agglomeration of lumps. The well proven Nibbler principle is based upon a cutting or grating action, Gericke Nibbler offer...

The Reductor: Coarse Size Reduction. Particle Size Range: 500mm to 20mm The Reductor is designed for pre-breaking blocks, lumps and slabs up to 500mm square with no restriction on the height of the material. A rotor assembly complete with internal discharge screw and cutting teeth mounted onto the outside of the drum rotates slowly to reduce the blocks to approximately 25mm pieces. Holes cut into the rotor body around the teeth allow the reduced pieces to pass into the discharge screw and out of the machine. The Reductor does NOT require a metered feed and can be used in combination with a...

The Nibbler: Medium Size Reduction. Particle Size Range 25mm - 1mm A gravity feed of product enters the nibbler which uses a low speed high torque rotating paddle assembly to sweep the material across a static serrated screen, inducing a cutting or grating action. The gap between the rotor blade and screen is fully adjustable and this movement together with a frequency inverter, used to change the rpm of the rotor, optimises the performance of the machine to deal with different material characteristics and to provide a controlled output feed with consistent particle size, without the...

Particle Size Range: 25mm - 1mm Five standard machine sizes: 200 x 200, 300 x 350, 300 x 450, 300 x 800 and 450 x 800 Quick release basket assembly with safety switch Side cleaning door(s) with safety switch. Fixed bearing and seal assembly Food quality seals and hygienic design Air purge seals Carbon steel and stainless steel contact part options Pressure rated casings Heating/cooling jackets FDA paint, bead blast and polished finishes Typical Applications Products Processed De-agglomeration after drying, spraying and mixing Activated Carbon Briquettes After storage in silo’s, big bags,...

The Cone Nibbler: Fine Size Reduction. Particle Size Range 6mm - 150 micron The Cone Nibbler incorporates a vertically mounted rotating tool which moves the material across a conical static serrated screen introducing a low velocity high impact cutting action into the product which is fed by gravity into the machine. Sub screen size product passes through the screen into the chamber whilst oversize particles not reduced by the first pass are carried by the vortex action of the tooling up towards the inlet returning it into the cutting chamber until the desired particle size distribution is...

Particle Size Range: 6 mm - 150 micron Three standard machine sizes: 150, 300 and 450 Quick release access to cutting chamber with safety switch Fully adjustable gap between rotor and screen Top adjustment of rotor gap from outside of machine IN-LINE CONE NIBBLER IN VACUUM CONVEYING SYSTEM Gap adjustment indicator Quick release rotor assembly Air purge seals Food quality seals In-line unit suitable for installation into Dilute Phase Conveying Systems Screen options range from 150 micron to 12 mm with various hole patterns. Pressure rated casings (10 Bar) Variable speed drives Mobile units...
