Description

Technical Field

[0001] The utility model belongs to the technical field of grinding mills, and more specifically, particularly relates to a vertical grinding mill. Background Art

[0002] Grinding mills are widely used in the grinding of mineral products in the fields of metallurgy, building materials, chemicals, mining, etc. Among them, the vertical grinding mill is equipped with a wind separation mechanism above the grinding chamber. The fine and light powder is sucked into the wind separation net through suction, and then passes through the wind separation net into the air duct and is transported to the collection device through the centrifugal force to obtain the ground powder. The powder blocks that do not meet the particle requirements fall back to the grinding disc in the grinding chamber for further grinding.

[0003] However, some large particles are too heavy to be sucked up by the air separation mechanism. Before they become powder, they move to the edge of the grinding disc during the grinding process and cannot be ground any further, causing some large particles to accumulate at the bottom of the grinding chamber and become inconvenient to handle.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a vertical grinding equipment is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a vertical grinding equipment to solve the problem that large-particle powder cannot be ground any further after moving to the edge of the grinding disc during the grinding process, resulting in some large-particle powder accumulating at the bottom of the grinding chamber and being inconvenient to handle.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting up the feed pipe and the recovery pipe, the feed port is led out away from the pulverizing chamber, and the suction fan is used to provide suction for the three-way pipe, so that the material particles at the feed mechanism enter the grinding disc of the pulverizing chamber through the feed pipe, and the suction of the three-way pipe also acts on the recovery pipe. The large particles of material that fall from the side of the grinding disc and cannot be sucked away by the air separator fall into the collecting bucket and enter the feed pipe again through the recovery pipe. The suction of the suction fan can be adjusted to make it much greater than the suction of the air separator, so that large particles of material can be circulated and ground, thereby improving the pulverizing efficiency and avoiding the accumulation of large particles of material in the pulverizing chamber.
