Used to reduce hard, friable materials like coal, rocks, ores, and minerals into a fine powder, typically to an analytical size of approximately 75 microns.

Used for grinding coal and coke into fine powder, these bench-type machines are designed for laboratories and industrial settings to prepare coal samples for analysis or research, and they can also be used with other materials for sample prepa [...]

Used to divide or halve dry materials such as cement, gravel, powdered ores, coal, coke, sand, soils, etc. Material poured into the hopper is divided into two equal portions by a series of chutes that discharge the material alternately in oppo [...]

Used for particle size analysis by separating a sample into different size fractions using a combination of horizontal oscillating and vertical tapping motions. It automates the sieving process to provide consistent and repeatable results for [...]

The Preiser Rotary Sample Divider (RSD) provides fast and accurate sub-division of coal, minerals, ash and other granular samples.
