wear-resisting plate

Primary Crusher Teeth and Jaws are a fundamental category within products for crushing & mixing, specifically classified as crushing tools. As essential wear and crushing tools, they are designed for the initial size reduction of bulk materials in mining and mineral processing. The primary function of these components is to endure extreme forces, placing them at the forefront of industrial crushing and mixing tools.

What are Primary Crusher Teeth/Jaws?
As core crushing tools, Primary Crusher Teeth and Jaws are installed on the movable/fixed jaw plates of jaw crushers or the mantle/concave liners of gyratory crushers. Their function is the primary mechanical crushing of raw coal or large-sized run-of-mine ore, reducing it to a size suitable for secondary crushing or direct screening. Operating under extreme conditions, these wear and crushing tools directly endure high-velocity impact and extreme compression from large, high-hardness material, resulting in severe abrasion within an exceptionally harsh environment.

Main Types and Corresponding Equipment
Primary crusher teeth/jaws, key products for crushing & mixing, are primarily differentiated by their crusher type. The first type is Jaw Crusher Jaw Plates (Jaws), which are flat crushing tools with wavy or triangular corrugations. A movable and a fixed jaw plate form a V-shaped chamber, using a compressive chewing motion suitable for various materials. The second type is Gyratory Crusher Liners (Mantle/Concave), conical wear and crushing tools with spiral grooves. The gyrating mantle against the stationary concave creates continuous compression and bending, making these components powerful crushing and mixing tools ideal for large-scale, high-tonnage primary crushing of hard and abrasive ores.
