Apr 29, 2021· 4. The fixed condition of the slip ring should be checked frequently to prevent the phenomenon that a large amount of dust and ore enter the body of the equipment body because the slip ring of the dust-proof seal box is not found in the operation of the cone crusher, which affects the operation of the equipment or even causes serious failure of the equipment;
The primary contributor to poor crusher performance is crushing chamber selection. If the fit between the mantle and concave – in combination with the eccentric throw setting – is incorrect, then the optimal reduction ratio cannot be achieved.
Sep 21, 2019· Cone crusher can also be called cone crusher in some areas. Because of the widely application of the cone crusher, it is very popular with our customers. However, the cone crusher may have some defects in the process of working, and do you know whyThe possible malfunction and its reasons of cone crusher are as follows:1.
The maximum crushing action is created by closing the gap between the hard crushing surface attached to the spindle and the concave fixed liners mounted on the main frame of the crusher. The gap opens and closes by an eccentric drive on the bottom of the spindle that causes the central vertical spindle to gyrate.
Sep 23, 2020· Low quality or low quantity of lubricating oil may also cause dry friction. When the dry friction between the main shaft and the cone sleeve of the cone crusher causes the temperature of the contact position to rise, it will result in the expansion of the cone sleeve and other serious consequences.
Oct 23, 2019· 4, moving cone and fixed cone problem. If the moving cone and the fixed cone of the crushing equipment are severely worn during production, they cannot play a full role in the operation, and the material cannot be sufficiently broken, which affects the quality of the discharge and may even cause congestion problems.
Initial material feed: When the cone is initially fed material, the chamber isn’t full, so the material goes down to the bottom of the chamber, causing the upper frame to bounce. Once the material is able to build up in the chamber, and the crusher is choke fed, the upper frame bounce will be eliminated. Allowing tramp iron into your crusher.
Dec 15, 2020· As we know, the working condition of cone crusher is generally very severe, which will cause damage to cone crusher. Also, improper operation and maintenance will cause damage of cone crusher. In the production process of cone crusher, there are 3 checks
Poor circulation of lubricating oil caused by blockage of oil return pipe and low oil return. Excessive impurities in the oil reduce the quality of the lubricating oil and cause abrasion inside the crusher, which will cause the crusher to overheat and the lubricating oil return temperature is too high.
1) For spring cone breaking, when the spring tension of the crusher is not enough, the crusher will often vibrate. 2) When the feeding of the crusher is uneven or excessive, it …
The hydraulic cylinder of the single-cylinder hydraulic cone crusher is at the bottom of the machine body structure and cannot form uniform pressure around it. When large particles on one side pass through, it is easy to cause a layer of discharge opening to be too large, so …
The operation is similar to the standard cone crushers, except that the size reduction is caused more by attrition than by impact. The reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30°.
The JOYAL Hydraulic Cone Crusher is widely used for secondary and fine crushing in the fields of mining, building materials, metallurgies and so on. The hydraulic cone crusher can crush materials with middle and high hardness such as, ironstone, copper ore, …
The first fault is too high oil temperature of cone crusher. There are usually several reasons for this failure. Firstly, the quality of the oil used in cone crusher is poor. Secondly, there is not enough oil left in the cone crusher. Thirdly, the bearing damage and serious friction of cone crusher causes the oil temperature to rise high.
"Uncontrollable High speed" is the fault phenomenon of cone crusher, refers to that in the production process, the rotating speed of cone crusher's moving cone suddenly increases, the body suddenly generates violent vibration, the safety spring or the safety cylinder is in abnormal working state, the working current increases instantly, and the oil return temperature rises sharply.
When the cone sleeve is running, non-broken material enters the crushing cavity (like iron), resulting in excessive load, which causes the fixed cone sleeve's zinc pouring off, causing the cone sleeve to go up, the clearance between the spindle and the cone sleeve becomes smaller, forming "holding shaft", the spindle will follow the eccentric sleeve to run quickly and form "uncontrollable speed".
1) For spring cone breaking, when the spring tension of the crusher is not enough, the crusher will often vibrate. 2) When the feeding of the crusher is uneven or excessive, it will often cause the crusher to vibrate.
3. Due to the serious wear or damage of the moving and fixed cone of the cone crusher, some oversized materials will be blocked at the discharge opening, which will cause the equipment to clog. Therefore, it is necessary to check the movement of the cone crusher regularly. Cone and fixed cone, problems occur in time.
Nov 28, 2020· Poor circulation of lubricating oil caused by blockage of oil return pipe and low oil return. Excessive impurities in the oil reduce the quality of the lubricating oil and cause abrasion inside the crusher, which will cause the crusher to overheat …
