Let’s all analyze the problems with the crusher; the answer is already available! There is a plate + hammer crusher with a power of 75 kilowatts, which is primarily used to crush coal into coal powder for use in boilers. The problem is this: during use, we noticed that the current drawn by the crusher became extremely high within half an hour of it starting up, and the bearing temperature was also very high. Despite several attempts at repair, it was difficult to resolve the issue. We repaired the bearing housing and the bearing caps, and we even purchased genuine bearings, but none of these measures solved the problem. Eventually, through careful analysis and discussion, we were able to resolve the issue. We would like everyone to share their opinions on the reasons behind this.
The belt of the crusher was too tight; after running for half an hour, the belt stretched out and the current supply was cut off!
Reply to 2# tjdxz: Not at all, let’s keep discussing!
Poor discharge from the outlet led to some accumulation of material, which caused the current level to rise.
Reply 4# mech: It’s an idea; it serves as a form of encouragement. Sometimes, the problems encountered during maintenance cannot be solved by using normal reasoning, haha. But whether it’s the reason or not, keep working hard!
:) Possible reasons: 1. During installation, the gap between the crushing teeth is small. 2. In terms of design, the quantities do not match, resulting in material blockage. 3. Misalignment of the shafts
Possible causes: 1. Excessive feed volume 2. Motor power not matching that of the crusher 3. Incorrect transmission ratio 4. Axial bearing clearance not meeting requirements 5. Excessive moisture in the feed 6. Improper installation 【Loose anchor bolts or incorrect level】
