1. Crushed mine: generally adopts small jaw crusher, roller crusher, disc crusher and single and double layer vibrating screen. The specifications of 98 fused magnesia crushing equipment can be determined according to the particle size of the ore and crushed products.

2, grinding, generally using a conical ball mill or cylindrical ball mill, rod mill, the former is mostly used in flotation or magnetic separation laboratory, the latter is mostly used for re-election of the laboratory.

3, rock and mineral identification: the production equipment generally uses slicer, grinding machine, polishing machine and inlaying machine, etc., medium and small dressing laboratory - generally do not set these devices. The identification equipment generally uses a polarizing microscope (for transparent minerals), a reflective microscope (for opaque minerals), and a photomicrography device. Medium and small laboratories generally only have high-power stereo microscopes.

4. Beneficiation: The ore dressing test equipment is determined according to the selection method. Commonly used equipment is:

1) Re-election generally adopts jig, centrifugal concentrator, spiral concentrator, shaker, hydraulic classifier, hydrocyclone and various chutes;

2) There are many types and specifications of flotation equipment, and it is necessary to determine the specifications and quantity according to the scale of the laboratory;

3) The dry magnetic separator generally adopts a single roll and a very strong magnetic separator;

4) Wet magnetic separator: magnetic separation tube, drum magnetic separator, magnetic dehydration tank, etc. are generally used for processing ferromagnetic minerals; flat ring and roller type strong magnetic separator are used for weak magnetic minerals;

5) Others: Test equipment such as electric selection, light picking, and friction selection may be added as needed.
