An iron remover in fact, a magnet can be added to the upper part of the belt conveyor to preclude the wire, nails, welding heads and the like.
Jul 07, 2021 Failure Analysis of Jaw Crusher. July 07, 2021. Jaw crusher is the key crusher equipment for stone crushing production. Many customers will meet various kinds of fault problems during production process, which will affect the whole production schedule. Here, We summarizes the common failure and treatment of the jaw crusher. 1.
1. The discharge port of the cone crusher is blocked, too much or uneven feeding will lead to the blockage of the discharge port, resulting in excessive production load of the crushing machine, resulting in the fracture of the fuse and lead to shutdown. 2.
Jun 17, 2021 Hydraulic cone crushers are widely used in crushing operations in many areas such as mines, construction, road construction, etc., and have the advantages of large crushing ratio, high work efficiency, and uniform product size, so they are deeply liked by users. Some customers have reported that after using the cone crusher for a long time, the discharge is too slow.
Aug 21, 2019 For the manufacturer of the cone crusher, the stable operation of the cone crusher is important during the use, followed by the crushing efficiency and the quality of the discharge.If the cone is of poor quality or improper use, the failure will result in downtime maintenance. Customers are very reluctant to see, because time is money, time is not waiting for people.
Mar 09, 2019 1 Moving cone imbalance. The vibration and moving cone action of the hammer crusher will cause the moving cone to wear, which will cause the center of gravity of the moving cone to shift to form an eccentricity, resulting in an unbalanced moving cone. The problems caused by the imbalance of the hammer crushing motor cone are 1 The moving ...
The secondary crushers are designated as Standard cone crushers having stepped liners and tertiary Short Head cone crushers, which have smoother crushing faces and steeper cone angles of the breaking head. The approximate distance of the annular space at the discharge end designates the size of the cone crushers.

May 26, 2021 3. Equipment Failure Of Cone Crusher. During the operation process of cone crusher, if the motor fails, it will cause damage to the pulleys and bearings, slippage of the conveyor belt and even burning. The motor cannot normally provide kinetic energy for cone crusher, which will also cause the raw material blockage in cone crusher. 4.
Mar 14, 2019 If the material in the crushing chamber of the cone crusher cannot be discharged in time, the cone crusher will block the material. In the case, the discharge port parameters are not changed according to the nature of the feed, so that the crushed material cannot be retained in the crushing chamber through the discharge port, causing the cone crusher to block the material.
Apr 15, 2020 Cone crusher discharge compartment maintenance If the under-crusher discharge compartment is not properly maintained and material builds up on the crusher arms or the countershaft box, crushed product will be restricted from exiting the crushing chamber, this will result in a low crusher throughput tonnage at an extremely high-power level.
Field Adjustments. Cone Crushers are configured with Hydraulic Lifting-Arm, where in the case of power failure, it allows the operator for rapidly rotating and removing the top-shell in order to remove the stuffed material inside the crushing chamber. The hydraulic adjustment unit will also allow easily and rapidly to perform the required setting adjustments, and changeovers of discharge ...
Cone Crusher Function A cone crusher has an annular crushing chamber. The CSS runs around the chamber so the action is basically rotational. Raw material enters the chamber on the OSS and is crushed one half revolution later by the CSS. This cycle takes place in most cone crushers
2. GYRATORY CRUSHERS The original patent for the gyratory crusher was granted to Phile- tus W. Gates in 1881. This fint crusher was used by the Buffalo Cement Co. At the time these early gyratory crushers were developed all mining and quarrying, either underground or open pit, was done
