Analysis of crushing effect of vertical impact crusher on tin ore

Tin is a silver-white metal with a strong gloss, a relative density of 7.0, a low melting point (230 ° C), a hardness of 3.75, and good soft ductility.

Tin is mainly used in the metallurgical industry to produce tinplate and various alloys. Tinplate is the main consumer of tin, accounting for about 40% of tin's consumption. It can be used as a container for food and beverages, as a variety of packaging materials, household appliances, and dry battery casings.

Tin ore is a non-ferrous metal ore, of which metal minerals account for about 20%, mainly including cassiterite, pyrite, iron sphalerite, and brittle sulfur, lead and zinc ore; gangue minerals account for about 80%, mainly quartz, calcite, and siderite.

1. Vertical impact crusher is a high-strength self-lined impact type ultra-fine crushing equipment.

2. The finite element calculation method is adopted in the rotor design to better meet the requirements of design and material selection.

3. After the equipment is manufactured, the electrical stress analysis of the rotor is carried out. The results are consistent with the finite element calculation. The accuracy of the finite element calculation is verified, and the safety and reliability of the actual rotor operation are verified.

4. The crushing test was carried out with materials of different properties such as sintered high alumina bauxite, waste magnet, steel slag, and tin ore, and the desired crushing effect was obtained.

5. Compared with the vertical crusher, the crushing particle size curve is in the same range, and the impact crusher achieves the crushing effect of the crusher.
