Description

Technical Field

[0001] This utility model relates to the field of mill feeding, specifically to a feeding device with a three-way valve. Background Technology

[0002] Feeding the raw materials into the mill is a crucial step in the grinding process, involving the accurate and uniform delivery of these materials for grinding. During this process, operators need to carefully control the feeding speed and quantity to ensure stable mill operation and achieve the desired grinding effect. Proper feeding not only improves mill production efficiency but also reduces energy consumption and wear, thereby enhancing overall production benefits.

[0003] The existing mill feeding devices still have the following problems in use:

[0004] After the mill starts up normally, the 307 three-way valve needs to be turned to the mill feed position. This requires manual opening of the manhole door and striking the valve plate with a sledgehammer to turn it to the correct position, which increases unnecessary operational risks and labor intensity.

[0005] When the mill malfunctions and cannot quickly reach the slag discharge chamber, it is still necessary to manually open the manhole and use a sledgehammer to strike the valve plate before it can reach the correct position. This increases the amount of material entering the mill, as well as the unnecessary safety risks and labor intensity.

[0006] Therefore, we have made improvements to this by proposing a feeding device with a three-way valve. Utility Model Content
