The most important components of common mixing equipment are as follows.
1. The occlusion between rotating parts and tangentially moving parts, such as power transmission belts and pulleys, chains and sprockets, racks and gears, etc.
2. Rotating shafts, including connectors, spindles, chucks, screws and rods, etc.
3. Rotated bumps and holes. Rotating parts containing bumps or cavities are dangerous, such as fan blades, cams, flywheels, etc.
4. The bite of opposing rotating parts, such as gears, mixing rollers, etc.
5. The intersection between rotating parts and fixed parts, such as spoke handwheels or flywheels and machine tool beds, rotating mixers and unprotected opening shell mixing devices, etc.
6. Close types, such as the hammer body of a forging hammer, the ram of a power press, etc.
7. Pass type, such as the workbench and bed of a metal planer, the blade of a shearing machine, etc.
8. One-way sliding parts, such as teeth on the edge of a band saw, abrasive particles of a belt grinder, convex movement belts, etc.
9. Between rotating parts and sliding parts, such as mechanisms on some flatbed printing machines, textile machine tools, etc.
