Sample Reduction Mining SGS

Sample Crushing. SGS laboratory staff most commonly use a jaw crusher as the primary crushing tool. These crushers can accommodate chunks up to 15 cm and can reduce them in size until 80% of the sample passes through a 2 mm screen. Staff then use ring and puck mills to prepare a smaller particle size if required for sample pulverizing.

Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones
