Description

Technical Field

[0001] This utility model relates to the field of ball mills, and in particular to a side-fixed vertical stirring ball mill. Background Technology

[0002] Vertical stirred ball mills are common equipment used for grinding or dispersing micron-sized powders. For ease of operation, vertical stirred ball mills have shafts installed on both sides of the mill jar, secured to the frame with bearings. This allows the jar to rotate and tilt around the shafts for easy unloading and operation. However, during operation, the jar must be fixed in place to prevent rotation. This is typically achieved by welding a fixing plate to the bottom of the jar and bolting it to the frame's crossbeams via connecting plates.

[0003] Due to factors such as processing and welding errors, the positions of the bottom fixing plate of the ball mill jar and the crossbeam of the frame are uncertain, requiring welding during assembly and painting only after welding. This leads to extended delivery times and wasted manpower and resources. Since the fixing plate and connecting plate are located at the bottom of the ball mill jar, their positions are very inconvenient for operators. Furthermore, when replacing the ball mill jar, the position of the fixing plate is difficult to determine, often resulting in misaligned bolts and holes. Utility Model Content
