Description

Technical Field

[0001] The utility model relates to the technical field of laboratory mineral processing equipment, in particular to a multi-grade wet screening device for a laboratory. Background Art

[0002] Traditional screening methods in mineral processing laboratories include dry screening and wet screening.

[0003] Dry screening is mainly performed by dry screening equipment. However, the problem is that the target material with compaction or clumping phenomena needs to be fully ground before screening. Otherwise, the screening efficiency and accuracy will be affected, especially when screening some difficult-to-screen materials. When the material is severely clumped, dry screening cannot be used and wet screening is the only option.

[0004] Wet screening primarily involves manually screening the target material using a standard sieve flushed with water. When a target mineral requires multiple fractions, the material under the larger mesh size is manually stored in a basin or bucket along with water. The material is then screened through a smaller mesh standard sieve, and the process is repeated multiple times. This multi-fraction screening method requires frequent screen changes and multiple screenings, resulting in complex operations, labor-intensive processing, and low efficiency. Utility Model Content
