Solving Methods of Usual Malfunction of Hammer Crusher

Today we will introduce the performance and structure of hammer crusher. Firstly comes the crusher briefly, thus, we can better understand the theme. Crushers mainly can be divided into jaw crusher, impact crusher, hammer crusher, roll crusher, combination crusher etc. . Here basically, we’ll make the hammer crusher introduction, and other types involved will be introduced in the following-up articles. Attention, please.
1. The bearing runs hot.
Reasons: The lubricating grease is insufficient; there are two much lubricating grease; the lubricating grease goes bad; the bearing is damaged.
Elimination ways: Add proper amount of lubricating grease; the lubrication grease inside the bearing should be half of its volume; clean the bearing; change new lubricating grease; change the bearing.
2. The granularity discharged is too big.
Reasons: The abrasion of the hammer is serious; the grate bar breaks.
Elimination ways: Change new hammer; change the grate bar.
3. The output decreases.
Reasons: The gap of the grate bar is blocked; the materials are not fed in an even manner.
Elimination ways: Stop the machine and clean the tamper inside the gap of the grate bar; adjust the material feeding mechanism.
4. There is knock on the elastic coupling.
Reasons: The pin roll is loose; the elastic ring is abraded.
Elimination ways: Stop the machine and tighten the pin roll nut; change new elastic ring.
5. There is knock inside the machine. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like stone crusher, Henan Hongxing is always doing the best in products and service.circular vibrating screen: http://www.china-hxjq.com/p21.html
Reasons: some materials that cannot be crushed go inside the machine; the fasten part of the lining board is loose and the hammer knock on the lining board; the hammer of other spare part breaks.
Elimination ways: Stop the machine and clean the crushing chamber; examine the tightness of the lining board and the gap between the hammer and the grate bar; change the broken spare parts.
6. The hammer crusher vibrates.
Reasons: The static balance of the rotor does not reach the requirement when changing the hammer or due to the abrasion of the cone head; the hammer breaks and the rotor loses its balance, the pin roll twists and breaks; the triangle plate or the round plate breaks; the foundation bolt is loose.
The main working part of this series of stone breaker is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the stone crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. There is a screening plate under the rotor, so that materials with size smaller than the screen mesh will be screened out and others are left to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.
