Description

Technical Field

[0001] The utility model relates to the field of grinding machine dust collection, in particular to a grinding machine dust collection mechanism for a cement laboratory. Background Art

[0002] When the cement laboratory conducts cement clinker testing, it needs to grind the cement into powder through a grinder before testing. The grinder will re-grind the raw materials, clinker, limestone and other samples to achieve the fineness required to pass through a 0.08mm square hole sieve. When the cement is ground to the same fineness, the tester takes out the powder for testing.

[0003] After long-term use, the grinding disc and clamping device of the grinder will be severely worn. During the grinding process, some samples will be thrown out of the grinding disc to generate dust. This dust will not only cause harm to the human body, but also cause environmental pollution, while aggravating equipment wear and shortening the service life of the grinder.

[0004] Therefore, a cement laboratory grinding machine dust collection mechanism is needed. Utility Model Content
