Crushing is often performed on bulk field samples of harder materials like ores, minerals, and rock. Crushers are often utilized as the first step of sample preparation before mills and pulverizers are used to further reduce particle size.
- Jaw Crushers - for primary size reduction of hard rock, ores and minerals are available in several different Bico and Heavy-Duty Morse models. Bico Chipmunk crushers are equipped with reversible plates that extend plate life, and the Badger model has a higher crushing capacity. Morse crushers are heavy-duty and designed for high throughput and oversize feed, and available in models with 3, 5 or 10hp motors.
- Portable Crushers – This new line of Hammermill and Jaw Crushers offers rugged construction, portability and versatility of use. All can be equipped with gasoline, diesel or electric power.
- Mini-Crusher – A 2x2in (51x51mm) feed opening crushes materials up to 1in (25.4mm) to 1/16in (1.6mm) and finer sizes. A ceramic jaw and cheek set can be ordered to avoid metal contamination, as can a tungsten carbide set for those tougher jobs.
- Marcy® Lab Cone Crusher – Ideal for reducing aggregates and mineral ores, the Marcy GY-Roll 6in or 10in Lab Cone Crushers have 300lb/hr or 600lb/hr throughput capacity. Throughput rate is dependent upon the material crushed; with coarser settings, throughput capacity may be higher.
- Holmes Hammermill Coal Crusher – With 1,000lb/hr or 4,0000lb/hr throughput, 2in or 6in feed size models effectively reduce bulk samples of coal and coke with rotor-swing hammers. Weights stated are approximate.
- Marcy® Double Roll Crusher – Double Roll Crushers are used in intermediate size reduction of medium hard to hard materials such as rock or ore, and can bridge the gap between laboratory and production outputs. Models with 3,000lb/hr or 8,000lb/hr capacity reduce most materials from 0.5in (13mm) feed size to minus No. 10 (2mm).
