Luoyang XTC launches a combined solution for primary and secondary crushing teeth and tertiary crushing segment in coal mines

As the "pioneer force" of the toothed roller crusher, the primary crushing tooth mainly undertakes the task of coarse crushing large pieces of raw coal and hard gangue. The newly launched primary crushing tooth adopts a high-strength alloy steel matrix and wear-resistant hard alloy composite technology, achieving both high impact toughness and high wear resistance. The unique enlarged tooth shape and optimized discharge angle design give it stronger crushing capacity and faster feeding response speed when dealing with large materials, reducing the risk of material blockage and laying the foundation for stable operation of the whole machine , while increasing the overall service life by 3-6 times.

 

 

 

Secondary crushing tooth: Precise Particle Size Control, Improved Crushing Efficiency

The secondary crusher teeth are responsible for further refining the particle size of materials. The new generation of secondary crusher teeth adopts a "gradient crushing surface" structure in its tooth shape design, which can effectively control the residence time of materials in the crushing zone, making crushing more uniform and stable. In terms of materials, the product uses high-chromium wear-resistant materials and hard alloy reinforcement technology, significantly improving wear resistance and life. Under continuous high-load conditions, its stability and wear resistance are outstanding, which can effectively reduce the frequency of equipment downtime and maintenance costs.

 

 

Tertiary crushing segment – wear-resistant fine crushing, achieving stable particle size control

 

The tertiary crushing segment is used for medium and fine crushing of materials after primary crushing. It is constructed from high-chromium cast iron, Cr-Mo alloy steel, or hard alloy brazed structure, offering advantages such as low wear rate, controllable particle size, strong bonding, and resistance to fragmentation. The segment can be customized according to customer operating conditions, making it compatible with various models of double-roll crushers.

 

 

Combining coarse and fine crushing creates a highly efficient crushing process.

 

The full-chain performance improvement across coarse, fine , and final crushing stages , but also features systemic innovations in structural optimization, material upgrades, and assembly methods . The primary crushing teeth handle the initial crushing of large materials, the secondary crushing teeth handle the secondary crushing, and the tertiary rollers complete the final particle size control. Actual operating data shows that, when used in combination, equipment efficiency increases by 20%–35%, wear-resistant part life increases by 2–5 times, downtime for maintenance is reduced by more than 30%, and energy consumption per unit output decreases by 10%–15%.

 

 

Helping the mining and coal industries reduce costs and increase efficiency

 

This combined solution provides coal mines and mineral processing enterprises with a more efficient, stable, and lower-maintenance crushing path. Luoyang Jinlu will continue to promote the innovative application of cemented carbide in the crushing field, contributing to the industry's intelligent and low-consumption development.

 

In the future, we will continue to deeply focus on the field of wear-resistant materials, constantly optimize the wear and crushing tools, surfacing and composite manufacturing processes, develop construction tools products with higher performance for crushing and wear resistance, and provide customers with more economical, efficient and reliable overall solutions for wear protection.
