Crusher Frame

Crusher Frame Overview

The crusher frame is the skeleton structure of large crushers such as cone crushers and jaw crushers, supporting all the working parts of the equipment, and its structural design has a greater impact on production. The crusher frame is a four-wall rigid frame with upper and lower openings, which is used to support the eccentric shaft and bear the reaction force of the crushed material. Small-capacity jaw crushers can also use good cast iron to replace cast steel. Large-capacity jaw crushers need to be cast in sections, and then reinforced with screws to form a whole. The casting technology is complicated. Jaw Crusher This series of products adopts cast steel crusher frame and movable jaw, with high strength and long service life. It has the characteristics of large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance and low operating cost.

1. The movable jaw and fixed jaw of the crusher continue to be used after the tooth shape is worn, and they are not repaired in time. 2. During production, the quality problems of the equipment itself caused by insufficient casting technology or welding. 3. The fixing of the fixed jaw plate is not strong enough, and the crusher works in a continuous vibration state for a long time, which causes the fixed jaw to become loose and hits the front wall of the crusher frame, causing damage to the frame. 4. The bolts of the crusher frame bearing are not tightened during installation, and there is a loose phenomenon. 5. The rigidity of the base of the main machine is out of tolerance or collapsed, causing the crusher frame to jump; 6. The direction of the flywheel counterweight is dislocated due to damage to the eccentric shaft, pin or loose expansion sleeve. 7. The selection of brackets and bracket pads is unqualified and cannot withstand huge impact force. When the crusher is subjected to strong impact, it cannot play the role of buffering and self-protection, resulting in damage or breakage of the crusher frame.

The Crusher Frame forms a load-bearing or process-facing structure within cement and heavy industrial equipment. Its performance cannot be judged by outside dimensions alone. Load path, mating parts, operating environment and the condition of the surrounding equipment all affect whether a replacement will fit correctly and run reliably. AGICO therefore reviews the component as part of the machine rather than treating it as an isolated catalogue item.

For a replacement project, the most useful starting point is the current drawing together with the equipment model and site observations. Wear photographs, failure location, maintenance history and measurements taken during shutdown help distinguish normal consumption from an interface, alignment or operating problem. This review allows the quotation to state the proposed supply boundary and the information that still requires confirmation.

The production route for the Crusher Frame is established after drawing review. It typically coordinates casting-process design, controlled melting and pouring, heat treatment and machining. Process hold points depend on material, geometry and the buyer's inspection requirements. Critical datums and machining references are identified early so that later operations protect the interfaces used during installation.

Inspection is planned around product risk rather than added only at final dispatch. Material chemistry and heat-treatment traceability; Casting surface and agreed NDT inspection; Machined datums, interfaces and overall dimensions; Final documentation, marking and release review. When a test or report is required, it should be listed in the enquiry so that sampling, acceptance criteria and document format can be agreed before manufacture. Final release checks also confirm marking, quantity, surface protection and the packing list.

AGICO can prepare a drawing-based Crusher Frame for new supply or replacement service. The technical review covers the requested material, configuration, interfaces, inspection scope and documentation. If the original drawing is incomplete, provide measurements, nameplate information and clear photographs; the missing points will be listed for confirmation. No order-dependent dimension or performance value is treated as final until it appears in the approved technical documents.

Packing is planned for component weight, geometry, transport mode and destination. Finished surfaces can be protected against handling damage and corrosion, while loose accessories and documents are identified against the packing list. For international delivery, buyers should state the destination, preferred trade terms, lifting or site-access restrictions and required arrival schedule so that the quotation can separate manufacturing scope from freight and local handling.
