Lab Sample Preparation

For chemical and physical analytical methods such as AAS, NIR, ICP or XRF, it is needing to crushing and grining the sample to analytical fineness. Our  lab sample preparation equipment is specially designed for this job for getting coarse, fine and ultrafine size reduction of almost any material.

ZJH minerals has decades of years experience on the lab sample preparation equipment for the industry of mining and minerals processing, geology, metallurgy. We will supply the machine and solutions for laboratory scale crushing, grinding and screening system.

Some sample is with Explosivity and Combustible Character. And some samples can not be oxidation during crushing.  How shall we crushing this kind of meterial?


  1. Consider the Hazardous features of the raw material, the crusher shall equipped with the dust collector with negative pressure. And the crusher is adopted the seal type.
  2. Consider the Explosivity, the crusher and dust collector shall equipped with explosion-proof motor
  3. Consider Combustible feature and prevent oxidization, the crusher shall be filling the inert gases when it is working. Our crusher is equipped with the open for filling the inert gases
  4. Process shouldn’t increase impurities or at the rate of minimum level, the crusher shall be equipped with zirconia crushing parts.
  5. The crusher is sealed type

ZJH minerals for laboratory sample preparation
