The "5 cavity types" for the CH440 cone crusher refer to the five specific profiles: EC, C, M, MF, and F. This classification is typically based on the configurations most commonly utilized in domestic aggregate production lines. Depending on the specific *Top Shell* (upper frame) employed, these five cavity types are primarily categorized into two major application scenarios:
• Maximum Feed Opening: Approx. 215mm (F85) / 250mm (F90).
• Characteristics: Accommodates the largest feed material sizes; offers extremely high throughput capacity, though the resulting product size is relatively coarse.
• Maximum Feed Opening: Approx. 190mm.
• Characteristics: A standard medium-crushing cavity type that strikes an excellent balance between feed size capacity and crushing ratio.
This group of cavity types features a narrower feed opening and a longer parallel zone; it is primarily utilized for tertiary crushing or for the production of manufactured sand.
• Maximum Feed Opening: Approx. 135mm.
• Characteristics: A typical fine-crushing cavity type, suitable for producing aggregates in the 20–30mm size range.
• Maximum Feed Opening: Approx. 95mm.
• Characteristics: Used for producing smaller-specification construction aggregates or serving as a preliminary stage for sand manufacturing.
• Maximum Feed Opening: Approx. 65mm.
• Characteristics: Imposes strict requirements on feed material specifications, yet yields a very high proportion of fine-grained product; ideal for the production of high-standard, premium-quality aggregates and sand.

Consider the "Upstream Process": If your feed material comes from the discharge of a jaw crusher (primary crushing stage), the EC or C cavity type (Size 5 frame) is typically recommended. If the feed consists of intermediate material that has already passed through a cone crusher or impact crusher, select the M, MF, or F cavity type (Size 4 frame).
Consider "Product Specifications": The finer the required product size (e.g., a high proportion of material under 10 mm), the more you should lean toward the F or MF cavity types; conversely, if the priority is maximizing throughput while maintaining moderate requirements for particle shape, select the C or M cavity types.
Note on Upper Frame Replacement: It is important to note that the EC and C cavity types utilize a Size 5 frame, whereas the M, MF, and F cavity types utilize a Size 4 frame. This implies that if you wish to switch from a C-type cavity to an M-type cavity, you will typically need to replace not only the liners (concaves) but the entire upper frame assembly as well.
