Size reduction is the process of breaking solid materials into smaller, more manageable particles through impact, attrition, or grinding.
It is an essential step in powder processing, helping achieve consistent particle size and improve material flow, mixing, solubility, reactivity, and overall downstream performance.
We've delivered mills into food plants, chemical reactors, mineral and metal powder lines, pharma floors and recycling operations. Hover any tile for the detail.
01Food & IngredientSugar, lactose, cocoa, dried spice and plant protein — soft, sticky and heat-sensitive feeds that have to hit a narrow micron band.Full 316L wet-clean contact surfaces, tool-free rotor access and a jacketed chamber that keeps the product below its melting point through the whole run.
02Mineral & MetalGypsum, limestone, silica and talc, plus aluminium, copper and alloy powders — hard, dense feeds that grind the machine as much as the machine grinds them.High-chrome and tungsten-carbide liners on every wear face, oversized bearings for continuous duty, and replaceable strike plates you change without pulling the rotor.
03Chemical & PigmentResins, polymers, dyestuffs and pigments — fine organic powders that build static and can carry an explosion risk in the chamber.Fully sealed and inertable housings, earthed and ATEX-ready builds, plus polished internals so one colour batch does not carry into the next.
04PharmaceuticalActive ingredients, excipients and sterile raw materials — high-value feeds where particle size decides dissolution and dose uniformity.Crevice-free 316L construction with sanitary seals, CIP-ready geometry and material traceability documents to support your validation file.
05RecyclePlastics, rubber, e-waste and battery black mass — mixed recovered feeds that arrive contaminated and never twice the same.Tramp-metal tolerant rotors, hardened breaker plates and a hinged chamber that opens in minutes so a jam costs you one shift, not one week.
06Battery & EV MaterialGraphite and silicon anode powders and cathode precursors — feeds where a trace of iron from the mill ruins the cell.Ceramic-lined chambers and media-free jet grinding, so the material is broken by itself and never touches a steel wear surface.
Every card carries how it works, what it suits, and the numbers — all five visible at once.
