In mining sites, the weight of a cone crusher mantle is a very important technical parameter. It directly determines the structural integrity of the equipment, the crushing force applied to the ore, and the sustainability of the crushing process. Clearly understanding the weight of the mantle is indispensable for the following tasks: stabilizing the machine, allowing the crusher base and foundation to be stronger so that the machine will not shake excessively or even collapse during operation; helping select cranes, since the mantle and its components generally weigh in tons and require cranes during replacement, enabling better crane selection and minimizing lifting risks; observing the flywheel effect during machine operation to evaluate crushing efficiency.

The total weight of the mantle assembly (including mantle casting, main shaft, mantle liner, and concave) varies significantly depending on the equipment model and specifications.
| Equipment Model | Mantle Assembly Weight (kg) | Mantle Assembly Weight (lbs) | Data Source |
|---|---|---|---|
| Metso HP100 | Approx. 1,250 kg | Approx. 2,755 lbs | [1] Metso HP Series Technical Parameters |
| Metso HP300 | Approx. 3,850 kg | Approx. 8,488 lbs | [1] Metso HP Series User Manual |
| Metso HP500 | Approx. 8,220 kg | Approx. 18,122 lbs | [1] Metso HP Series Product Brochure |
| Sandvik CH430 | Approx. 3,300 kg | Approx. 7,275 lbs | [2] Sandvik Product Guide |

To ensure these heavy components strictly meet the above precise specifications, the mantle manufacturer Duma is equipped with a large integrated production base covering 42,000 square meters. Through full-process independent control (from raw material inspection to final machining), Duma can ensure that each casting meets the precise weight and dimensional tolerances required by international brands such as Metso and Sandvik.
Which Component Is the Heaviest?
The mantle is composed of the mantle liner, concave, and locking nut. Among these components, the mantle liner is the heaviest, followed by the concave. According to the official parts databases of Sandvik and Metso, the mantle of Sandvik CH440 weighs 643.65 kg, while the concave of the same model and cavity type weighs approximately 500–600 kg; the mantle of Metso GP300S weighs 962.9 kg, while the concave of the same model weighs 881 kg.

The "mantle" is not a single component, but an assembly of several key parts, including the mantle body, mantle liner, concave, locking nut, etc. These components work together to complete the crushing process, and the total weight is distributed among multiple key parts:
Cone crusher mantle and concave liners are core wear-resistant liners. High-quality liners are made of high-density high-manganese steel (Mn13, Mn18, or Mn22). This type of material provides the mass required for crushing hard ore while maintaining structural stability.
The cone crusher mantle locking nut, although smaller than the mantle liner, is a heavy-duty specialized fastener. The locking nut must ensure precise fit through precision machining so that it can avoid loosening as much as possible under severe vibration conditions.
The structural base mass includes the internal mantle casting used to support all liners. It is recommended that liners undergo controlled solution heat treatment (water toughening), which ensures a stable austenitic structure and enables the heavy assembly to resist brittle fracture. Duma follows this approach.
The mantle will continuously lose mass during the rock crushing process, and the loss is usually up to 15%–25% of the original weight. Operators rely on the consistency of casting performance to predict the replacement cycle. If rigorous high-magnification metallographic inspection and non-destructive testing (ultrasonic / magnetic particle testing) can be carried out, then this stability can be better guaranteed, and the possibility of premature mantle fracture caused by internal defects will be greatly reduced. Clarifying the component weight is the basic prerequisite for safe operation. Whether it is a brand-new mantle or a scrapped liner, the lifting team must use certified equipment for the operation. From the precision-manufactured mantle locking nut to the large mantle and concave assemblies, weight is an important indicator for evaluating crushing capacity.
