SHANVIM Introduces Integrated Multi-Tooth Jaw Plate for High-Efficiency Fine Crushing and Aggregate Shaping

Jinhua, China — SHANVIM, a leading manufacturer of wear-resistant crusher spare parts for the global mining and aggregate industries, today announced the release of its new Integrated Multi-Tooth Jaw Plate (IMTJ). The product is engineered to significantly improve crushing efficiency, deliver more uniform product sizing and extend service intervals for fine-crushing and aggregate-shaping applications.

The new jaw plate is the latest addition to SHANVIM’s growing portfolio of high-manganese steel wear parts, which already serves customers across Russia, Indonesia, Australia, Finland, Central Asia, Europe and beyond. Designed for crushers operating in secondary fine-crushing and recycling duty, the IMTJ plate responds to a clear market demand: operators want more consistent output, faster installation and lower per-tonne wear costs without investing in entirely new machinery.

One-Piece Casting, Multiple Teeth: A Smarter Geometry
Unlike conventional jaw plates, which consist of a single broad plate with one row of teeth, the SHANVIM Integrated Multi-Tooth Jaw Plate combines several rows of teeth into a single, integrated cast body. This one-piece structure is the heart of the product’s performance advantage.

The multi-tooth geometry creates a denser pattern of crushing peaks and biting points across the entire crushing cavity. When the moving jaw closes against the fixed jaw, material is engaged at multiple points simultaneously rather than at a single wide surface. The result is a more aggressive and stable gripping action that holds feed material firmly in place.

Key benefits of the multi-tooth design include

Stronger material grabbing and less slipping. The dense tooth arrangement prevents hard-to-hold feed — such as wet or fine material, construction debris and asphalt millings — from sliding upward and out of the cavity. This keeps the crushing chamber full and the operation stable.

Uniform product size and better particle shape. The special tooth profile and optimized cavity curve deliver a more consistent crushing and shearing path. As a result, operators achieve a well-shaped, cubical final product with fewer flaky or elongated particles, which is especially valued in aggregate shaping and concrete recycling.

Finer crushing capability. The finer tooth geometry is tailored for secondary and tertiary reduction, allowing a standard jaw crusher to be switched into fine-crushing duty simply by changing the wear plate — no new machine investment required.

Designed for Faster Installation and Lower Downtime
One of the most practical advantages of the IMTJ plate is its one-piece, ready-to-fit design. Because all teeth are cast onto a single base, the plate is installed as one component rather than several separate segments that must be individually aligned and gapped.

This delivers measurable value on the job site:

Significantly reduced installation time. Technicians no longer need to align, shim and adjust each separate tooth segment. One piece in, one piece out — a faster changeover that shortens planned maintenance windows.

No risk of segment misalignment. Because there are no independent segments to work loose or shift during operation, the crushing cavity keeps its designed geometry throughout the wear life, avoiding the efficiency loss caused by drifting plates.

Lower skill requirement for changeouts. The simple, foolproof fit reduces the chance of installation error, making maintenance easier for crews of all experience levels.

Superior Structural Rigidity and Uniform Wear
The integrated casting gives the IMTJ plate greater overall rigidity than segmented or multiple-piece jaw plates. Because the load from the crushing stroke is distributed across one continuous body, stress is spread more evenly, reducing the risk of a single tooth or segment cracking, loosening or breaking under heavy shock loads.

Equally important is uniform wear behaviour. Since all teeth are part of the same body and work against the same feed, they wear at a consistent rate. Operators benefit from:

Fewer unexpected failures. A rigid, evenly loaded body is far less prone to the tooth fracture and segment loosening that can shut down a line.

Less frequent maintenance. Instead of inspecting and replacing individual teeth at different times, the whole plate can be changed as a unit at a predictable interval, simplifying inventory planning.

Predictable, lower total cost of ownership. A single wearable part with consistent life means simpler stockholding and less unplanned downtime — two factors that directly improve operating profitability.

Wide Application in Fine Crushing and Recycling
The Integrated Multi-Tooth Jaw Plate is ideally suited to the following operating conditions:

Secondary fine crushing of aggregate and quarry stone, where consistent sizing is critical;

Construction and demolition waste recycling, including concrete and asphalt millings;

Aggregate shaping and cubical product requirements, where particle shape directly affects selling price;

Low- to medium-hardness materials that benefit from a denser tooth pattern rather than heavy-duty coarse crushing.

It is worth noting that, by design, the IMTJ plate is not intended for primary coarse crushing of large, hard rocks, where feed size is large and impact is extreme. It is a purpose-built solution for the fine-crushing and shaping stages, where its strengths are most fully realised.

Premium Materials, Rigorous Quality Control
Consistent with SHANVIM’s commitment to durability, the IMTJ plate is manufactured in high-manganese steel grades such as Mn13Cr2 and Mn18Cr2, selected for their excellent impact toughness and work-hardening behaviour. As the manganese content is work-hardened under crushing pressure, the surface becomes progressively harder while the core remains tough — the ideal combination for a long-service wear part.

Every plate is produced under strict quality control, with careful attention to casting integrity, tooth geometry and dimensional accuracy to ensure a precise fit for the designated crusher model. SHANVIM also offers customized cavity design and material selection to match the specific crushing chamber, feed characteristics and production targets of each customer’s operation.

SHANVIM as a global supplier of crusher wearing parts, we manufacture cone crusher wearing parts for different brands of crushers. We have more than 20 years of history in the field of CRUSHER WEAR PARTS. Since 2010, we have exported to America, Europe, Africa and other countries in the world.
