Dual-core jaw crusher--Innovative crusher
Anhui SUHMAN Engineering Machinery Co., Ltd.,a military-grade factory specializing in the R&D and production of various types of crushers. We are committed to improving crushing and screening performance, breaking through existing technological limits, and providing advanced tracked mobile crushing and screening solutions for customers in various industries worldwide. Suhman has now launched its new star product – Dual-Core Jaw Crusher, which redefines the crushing efficiency and versatility of jaw crushers.
In the mining and aggregate industry, achieving higher yield and better particle shape with lower energy consumption and less investment has always been a core consideration in equipment selection. Jaw crushers, as pioneers in crushing, have been the preferred choice for centuries due to their simple structure and powerful crushing capacity. Currently, the vast majority of jaw crushers on the market are compound pendulum jaw crushers. The biggest drawback of this type of crusher is that the crushing work on the material decreases as it moves towards the discharge port, and there is almost no possibility of crushing near the discharge port, resulting in a small crushing ratio.
Suhman has innovatively developed a dual-core jaw crusher, structurally solving the problem of insufficient crushing force distance at the discharge port. The inverted moving jaw provides a complete crushing stroke at the discharge end, thus achieving a super-large crushing ratio. While the common compound pendulum jaw crusher has a crushing ratio of 3 to 5 times, the dual-core jaw crusher can achieve a maximum crushing ratio of 15 times, thereby enabling a single machine to complete the entire process from raw materials to aggregate.
Working principle
Two nearly identical movable jaws are arranged in a rotationally symmetrical "V" shape (the jaw plates of the two movable jaws are identical and interchangeable). When the raw material enters the jaw crusher inlet, the upright movable jaw provides maximum crushing stroke and crushing force through an eccentric shaft. After the raw material is gradually crushed, it falls towards the discharge port. The inverted movable jaw at the discharge end also provides maximum crushing stroke and crushing force through an eccentric shaft, thus ensuring that the raw material receives complete crushing work throughout the entire crushing process, achieving a very high crushing ratio.
The two rotationally symmetrical movable jaws are connected by a belt to transmit power synchronously. When the eccentric shaft rotates 90 degrees, both movable jaws move simultaneously to either side of the center line of the "V" shaped cavity. A further 180-degree rotation moves both jaws towards the center line of the "V" shaped cavity, crushing the raw material. Afterward, a 90-degree eccentric rotation returns the jaws to the starting point, completing one full crushing cycle.
Technical parameters
The data from the equipment doesn't lie; if you want high performance, you need good technology.
| Max feed size | 1000mm | Allows for large-sized raw materials without pre-crushing. |

| Net weight | 12t | Q345 grade steel provides better earthquake resistance. |
| Power | 140kw/Eight-stage motor | More powerful performance |
| Rotational speed | 300/min | Optimal operating speed ensures efficiency while reducing energy consumption. |
| Output | 150-350TPH | It depends on the specific raw materials and the feeding rate. |
Comparison with traditional crusher
Producing Stones Smaller than 4.5cm: 50% Higher Finished Product Rate
When producing stones smaller than 4.5cm (45mm), traditional 1060 or 1160 jaw crushers often suffer from insufficient discharge end stroke, resulting in "insufficient crushing and incomplete crushing," leading to a high proportion of coarse material in the finished product, requiring re-crushing.
However, the dual-core jaw crusher, with its powerful crushing force throughout the entire stroke of the lower moving jaw, achieves a 50% higher finished product rate for stones smaller than 4.5cm compared to traditional 1060/1160 crushers. This means that with the same feed rate and energy consumption, you can obtain significantly more qualified fine material, greatly improving the effective output of the production line.
Sand Making/Shaping Process: Eliminating a Cone Crusher, Significantly Reducing Investment
In traditional medium-hard or hard rock sand making/shaping production lines, the process flow is typically: Jaw Crusher + Cone Crusher + Vertical Shaft Sand Making Machine (Shaping).
Today, a dual-core jaw crusher can replace the combined role of a jaw crusher and cone crusher. The new process simplifies to: a dual-core jaw crusher + a vertical shaft impact crusher.
Advantages: Reducing the need for a cone crusher not only significantly saves on equipment procurement, civil engineering, and installation costs compared to traditional models, but also eliminates the need for intermediate belt conveyors and electrical control systems, resulting in a smaller production line footprint and significantly reduced maintenance points and wear parts consumption.
Hard Rock, Water-Stabilized Materials, and Crushed Stone Subbase: Single Unit Replaces Jaw Crusher + Cone Crusher Combination
When processing hard rocks such as granite and basalt, or producing road water-stabilized materials and crushed stone subbases (stone with a size of less than 4cm), traditional methods require a two-stage crushing combination of a jaw crusher (coarse crushing) and a cone crusher (medium crushing) to achieve the desired finished product rate and particle shape.
The dual-core jaw crusher, with its high crushing ratio of 15:1 and powerful extrusion force, can achieve the finished product rate and output particle size of a traditional jaw crusher + cone crusher combined production line with a single unit. One machine does the work of two, making it particularly suitable for applications with limited space, high cost-effectiveness, or mobile crushing plants.
The dual-core jaw crusher, with its powerful crushing efficiency, has a wider range of applications and can significantly reduce equipment costs. More and more customers are choosing this new type of equipment. Want to learn more? Suhman – China's leading crusher manufacturer – is available 24/7 to answer your questions!
