This technique requires skilled welders to ensure strong defect-free joints that can withstand the applied load without breaking. Safety measures include grounding the crusher to prevent electrical hazards and using heat-resistant barriers to protect adjacent components.

Implementation begins with cleaning the object's surface to improve weld adhesion and selecting appropriate filler metals based on the object's material composition. Force application must be gradual and aligned with the extraction path to avoid bending or snapping the object. Post-extraction the welded fixture is removed and the area is inspected for any residual weld material that might interfere with operation. This approach is particularly useful for deeply embedded objects that resist mechanical pushing or prying.

Oxygen-Acetylene Cutting Decomposition in Extreme Cases

Oxygen-acetylene cutting is employed as a last resort for fragmenting large irremovable metal objects within the crusher chamber using high-temperature flames to melt and sever the material. This process demands specialized training in gas handling and flame control to prevent explosions or unintended damage to crusher components. Operators must wear full protective gear including flame-resistant clothing and goggles and ensure that the work area is clear of combustible materials. The technique is reserved for situations where other methods have failed and the object's value justifies the risks.

Cutting proceeds in small sections to manage heat input and avoid thermal distortion of the rolls or nearby structures. Cooling sprays may be applied intermittently to control temperatures and minimize the risk of warping. Post-cutting the fragments are removed manually and the chamber is inspected for heat-affected zones that might require repair or replacement. This method highlights the importance of having contingency plans for the most stubborn jams while upholding strict safety protocols.
