Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like figure 1 As shown, an improved ball mill includes two bearings 1 and a cylinder body 2. The hollow shaft heads at both ends of the cylinder body 2 are fixedly supported by the two bearings 1. It is characterized in that a supporting device is provided outside the cylinder body 2.

[0016] The supporting device of the present invention is a single group or multiple groups; the supporting device includes a transmission belt or a transmission ring 3, a rolling device 4 and a support 5, and the transmission belt or the transmission ring 3 is sleeved on the outer circumference of the cylinder 2, and the rolling device 4 Mesh with drive belt or conveyor ring 3, rolling device 3 is fixed by support 5

[0017] This structure adopts several supports within the length of the cylinder to ensure multi-point support during the operation of the equipment...

Abstract

The invention discloses an improved ball mill, comprising two bearings (1) and a barrel, wherein, hollow shaft heads of two ends of the barrel (2) are fixed and supported by the two bearings (1), a supporting unit is arranged outside the barrel (2); the supporting unit can be a single set or a plurality sets, the supporting unit comprises a driving belt or a conveying loop (3), a rolling unit (4) and a support (5), the driving belt or the conveying loop (3) is sleeved on the external circumference of the barrel (2), the rolling unit engages with the driving belt or the conveying loop (3), and the rolling unit (4) is fixed through the support (5). According to the invention, a plurality supports are arranged in the length of the barrel to guarantee the multi-point supporting in the running process of the device, thus the bearing capacity of the two ends is reduced, the fatigue damage of the barrel is reduced, and the long-time normal running of the device can be guaranteed.

Description

technical field [0001] The invention relates to a ball mill, especially a ball mill with a fixed supporting device, in particular to an improved ball mill. [0002] Background technique [0003] At present, the rotating mechanism of the main cylinder of the ball mill generally adopts hollow shaft heads at both ends, supported by rolling self-aligning bearings, and ensures that the main cylinder rotates in a certain direction. However, due to the long-term load operation state, fatigue damage is caused to the connecting parts of the shaft end, resulting in cracks and fractures in some parts, resulting in the failure of the equipment to operate normally, resulting in consequences such as shutdown, and maintenance is also very difficult, and the losses caused cannot be Estimate. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the main cylinder of the ball mill has fatigue damage to the connecting parts of the shaft end du...
