SAMPLE PREPARATION

Laboratory Crushers & Sample Preparation Equipment

Laboratory jaw crushers, hammer crushers, and double-roll crushers for rock, aggregate, concrete, clinker, mineral, and coal sample preparation.

Lithostek laboratory sample preparation equipment is selected around the complete reduction workflow: maximum feed size, target output range, required throughput, material hardness and toughness, moisture, contamination limits, wear-part material, batch or continuous operation, electrical supply, dust control, and downstream milling. A laboratory jaw crusher is normally the primary reduction stage; hammer and double-roll crushers provide alternative or secondary reduction where material behavior and the required particle-size distribution make them more suitable. Published output size is a crusher setting, not a guarantee that every particle passes a specified analytical sieve, so representative sampling and any required fine grinding must be planned separately. For coal projects, the configuration can be reviewed against the crushing stages referenced by ISO 13909-4; this is workflow mapping, not machine certification. Related materials workflows are available in Aggregate Testing, Concrete Testing, Cement & Mortar Testing, and Rock Mechanics.

Performance Selection Criteria

Start with the largest feed particle

Confirm the largest dimension and representative batch mass. The crusher inlet and practical feed limit must accommodate the real sample without unsafe pre-breaking.

Define the next process, not only the gap

State whether the crushed sample goes to splitting, sieving, pulverizing, chemical analysis, or a materials test. Crusher discharge settings do not replace downstream milling when sub-millimetre powder is required.

Match the crushing principle to the material

Use jaw crushing for robust primary reduction, hammer crushing for brittle materials and higher reduction ratios, and double-roll crushing where controlled narrow output and low over-grinding are priorities.

Control contamination, dust, and access

Confirm jaw, hammer, roll, and liner materials; cleanout access; sealed enclosures; extraction connections; interlocks; emergency stop; noise; voltage; and phase before quotation.

Frequently Asked Questions

Choose from the material, maximum feed size, target output, batch mass, hourly throughput, moisture, contamination limit, and next preparation step. Jaw crushers are the usual primary stage; hammer or double-roll crushers may be better for brittle feed, higher reduction, or controlled secondary crushing.

Usually not. A jaw crusher commonly reduces coarse feed to millimetre-scale material. Chemical, XRF, or other analytical workflows may still require representative splitting and a disc mill, ring mill, or other fine pulverizer after primary crushing.

No. The setting controls the crushing gap or selected screen, while the actual particle-size distribution depends on feed shape, mineralogy, moisture, wear condition, loading, and operating technique. Confirm any all-passing requirement separately.

Yes. Jaw plates, hammers, screens, rolls, liners, dust connections, collection trays, voltage, phase, frequency, and documentation can be reviewed for the sample and destination laboratory before quotation.
