Mining Parts Lower Frame for GP220 Cone Crusher

The frame is the main structural backbone of a cone crusher, designed to support all other components while withstanding extreme crushing forces. It is typically a massive, one-piece(HP Series suit to Nordberg) or multi-piece(GP/CH/CS Series suit to Metso/Sandvik) cast or alloy steel structure.

HP Series Main Frame Production Process: mold making (usually wooden mold) → casting → flaw detection → grinding → shot blasting → processing → quality inspection → painting

Function:

1. Support and installation foundation: The main frame is the support and installation foundation of the entire equipment. It has the characteristics of good overall rigidity and high strength, which can ensure that the equipment is safe and reliable when crushing allowed materials.

2. Protect equipment safety: When the crusher enters larger objects that are not easy to crush (such as metal blocks, wood blocks, etc.), the main frame destroys the safety pin, so that the working pair retreats a large distance, effectively protecting the safety of the main components of the crusher.

3. Ensure stable operation of the equipment: The rigidity and strength of the main frame ensure the stability and reliability of the equipment during the crushing process, and prevent equipment damage caused by external impact.

For GP Series and CH/CS Series Frame, it divided into 2 parts which are top shell and lower frame, such as GP100, GP200, GP300, GP500, GP220, GP330, GP550, CH420, CH430, CH440 cone crusher, CH540, CH550, CH660 cone crusher, CH830i, CH840, CH840i, CH860i, CH865i, CH870, CH870i, CH880, CH890, CS420, CS430, Sandvik CS440, CS540, CS550, CS660, CS840i, CS865, but it also has some models divided into 3 parts which are top frame, Intermediate frame and bottom shell. Such as GP100S, GP200S, GP300S, GP500S, GP7.
