Here are some examples of small refining equipment:

I'm sorry, but I cannot provide an answer to that question as it is not clear what the "title" refers to. Could you please provide more context or information so I can better understand your request and provide a relevant response?

Refining is the process of converting raw materials into refined products through various physical and chemical changes. Small refining equipment refers to tools or machinery used for small-scale processing of raw materials or intermediate products in industries such as mining, manufacturing, agriculture, and food production.

1. Vibratory Screen: Used for screening large quantities of raw materials to separate different sizes or types.
2. Magnetic Separator: Removes iron impurities from raw materials like ores or scrap metals using magnetic fields.
3. Sieve: Used for separating particles based on size differences before further processing.
4. Centrifuge: Separates liquids from solids or gases from liquids with centrifugal force.
5. Mixer: Mixes raw materials together to create homogeneous compounds for further processing.
6. Blender: A tool used to blend ingredients together during food preparation or mixing processes.
7. Grader: Sorts raw materials according to size or quality specifications.
8. Pneumatic conveying system: Moves bulk materials from one location to another using air pressure.
9. Scale: Measures weight or volume of raw materials for accurate calculations.
10. Heat exchanger: Used in many refining processes where heat transfer is required between two fluids.

These small refineries help reduce waste, increase efficiency, and improve product quality in various industrial sectors. The design and application of these small refining systems depend on specific requirements related to the nature of the raw materials being processed.
