In order to facilitate the observation of the rod grinding process, there is an observation window on one side of the outer cover.

The outer cover is also provided with a ventilation fan, and the top of the outer cover is also provided with a lighting device.

In order to reduce dust flying, there is a dust funnel on the rack below the grinding rod platform, and the dust funnel is connected with a dust collection bag.

The beneficial effect that the utility model can reach is:

1. The utility model has reasonable structure, high degree of automation, stable product quality, greatly reduced labor intensity, and eliminates most of the safety hazards due to the reduction of human operations.

2. The working environment of the utility model is airtight, and most of the dust is collected, which ensures the physical health and environmental sanitation of workers.

3. The utility model is not affected by factors such as the site and the length and thickness of the mandrel, and has a wide range of applications.
