鄂式crusher maintenance content

The primary repair methods for jaw crushers are minor and medium repairs. By maintaining the equipment through these repairs, the scope of major repairs can be determined.

Above is the鄂式破碎机 produced by our company, suitable for crushing ores in various engineering projects.

The main content of the minor maintenance: Inspection and repair of adjustment devices, adjustment of ore discharge gap; Replacement of worn-out liners and thrust plates; Repair and replacement of transmission parts; Cleaning individual components of the crusher; Replacement of lubricating oil and repair and adjustment of the lubrication system, etc. Typically performed every half month or month, depending on specific circumstances.

The main content of the mid-term maintenance includes all the work of minor maintenance. It involves replacing worn-out shaft bushes, rods, pads, thrust plates; inspecting, turning, grinding, and casting eccentric shaft bushes, connecting rod head bushes, and moving jaw shaft bushes, etc. The interval between two mid-term maintenances depends on the wear condition of the main shaft bushes, connecting rod head bushes, and moving jaw bushes, usually occurring once a year.

The main contents of the major overhaul include all the work from the medium repair. This involves replacing and turning the eccentric shaft and swing jaw shaft; casting Babbit metal on the top of the connecting rod; replacing and restoring all worn parts and components; aligning the entire crusher, and carrying out technological innovation on the equipment. The interval between two major overhauls primarily depends on the wear condition of the eccentric shaft and swing jaw shaft, typically occurring every four years or so.

Many mining plants are currently opting for the repair of crushers by replacing entire components, known as the pre-maintenance method. During repairs, simply remove the worn-out parts and replace them with new ones, significantly reducing machine downtime and improving equipment operation efficiency.
