Size Reduction

Crusher and Mill Solutions for Sample Preparation

From heavy-duty MACSALAB jaw crushers and high-capacity hammermills to precision lab mills and smooth roll crushers, Eriez size reduction solutions optimize feed size conditioning and grinding performance across a wide range of minerals, ores, coal and industrial samples.

Barrel Mill

Variously known as a Barrel Mill, a Swing-Mill, a Ring Mill or a Stone and Disc Mill, this highly efficient grinding machine comprises a steel vessel containing a solid steel bar (stone) and one or two steel rings, which oscillate with a rotary motion to grind materials from approximately 10 mm lumps down to powders finer than 50 microns.

Finger Crusher

MACSALAB Finger Crushers are of the double rotor type designed for breaking lumps of moderately hard materials, especially those tending to agglomerate in storage.

Hammermill

The MACSALAB Hammermills are specially designed and fabricated for the reduction of medium to hard friable materials.

Jaw Crusher

The range of MACSALAB Jaw Crushers is ideal for primary crushing of samples of moderately hard materials, including coal, limestone, ore, minerals and bricks and rubble. Units are sturdily constructed in Cast Iron and utilise reversible hardwearing Manganese Steel jaws.

Lab Mill 200

The 200 Cross Beater Lab Mill is used for crushing coal, chemicals, spices, bricks, soil, grain, ores and minerals, concrete and many more materials in the medium hard range. Once the material is fed into the feed chute, it quickly flows into the mill grinding chamber where it is pulverised against the chamber lining by impact with the fast moving hardened hammers.

Overhung Hammer Mill

The MACSA 300 Overhung Hammermill (Disintegrator Mills) have been introduced to satisfy the needs of laboratories, research institutions and industry requiring size reduction on a semi production scale. MACSA 300 Overhung Hammermills have been successfully installed in the coal, minerals and ore, sugar, food, chemicals and fryable grain.

Rod and Ball Mill

The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.

Rolls Crusher

MACSALAB Rolls Crushers are designed for secondary reduction after jaw crushing. These smooth roll crushers will rapidly reduce coal, ore and hard rock from a maximum feed size of 20mm to fine sand. Ruggedly constructed & easy to operate. Breakage of material is by nipping action with minimal fines generated.
