Concave Mantle manufacturer


Overview


Engineered for robustness and reliability, these parts are ideal for processing hard and abrasive materials such as granite, basalt, and iron ore. Crafted from premium-grade materials like high-chromium alloy and heat-treated steel, Jaw Crusher Parts are built to withstand the extreme impact and pressure inherent in heavy-duty crushing operations. Their innovative design focuses on minimizing downtime, reducing maintenance costs, and maximizing throughput, making them strategic choice for mining, construction, and recycling industries seeking long-lasting crushing solutions.


Features


1. Enhanced Wear Resistance with Composite Material Technology

The fixed and movable jaw plates of Jaw Crusher Parts feature proprietary composite material combining the toughness of alloy steel with the abrasion resistance of tungsten carbide coatings. This hybrid structure increases wear life by 30% compared to traditional manganese steel plates, even in highly corrosive or abrasive environments. The optimized tooth profile with variable spacing ensures uniform material grip, reducing slippage and improving crushing efficiency by up to 25%.


2. Precision-Machined Eccentric Shaft with Dynamic Balance

The eccentric shaft, critical drivetrain component, is manufactured using CNC machining for micron-level precision. dynamic balancing process eliminates vibrations, reducing stress on bearings and extending their service life by 40%. The shaft is heat-treated to HRC 48-52, providing superior resistance to torsional fatigue and heavy loads, ensuring smooth operation even at maximum capacity.


3. Hydraulic Toggle Plate Adjustment System

A newly integrated hydraulic system allows for tool-free adjustment of the toggle plate, enabling quick and precise control of the discharge opening (ranging from 10mm to 150mm). This feature eliminates manual wedge adjustments, reducing setup time by 50% and ensuring consistent particle size output. The hydraulic system also includes overload protection, automatically retracting the toggle plate to prevent damage from uncrushable materials, such as metal contaminants.


4. Low-Maintenance Sealing Design

All moving joints feature double-lip seals with labyrinth grooves, effectively blocking dust and fine particles while retaining lubrication. This design reduces bearing failure rates by 60% and minimizes the frequency of lubrication maintenance, making Jaw Crusher Parts suitable for harsh, dusty environments common in open-pit mining and quarrying.


Applications


1. Mining Industry

Jaw Crusher Parts excel in primary crushing of hard ore deposits, including gold, copper, and iron ore. Their high wear resistance makes them ideal for processing ore with up to 300 MPa compressive strength, reducing replacement costs in deep-mining operations. They are commonly used in mineral processing plants to break down raw ore into feed sizes suitable for secondary crushers or grinding mills.


2. Construction & Infrastructure

In the construction sector, these parts are critical for producing aggregates for concrete, asphalt, and road base materials. The adjustable discharge opening allows customization for different project requirements—from coarse gravel for road subbase to medium-sized aggregates for concrete batching plants. They also process construction waste, such as recycled concrete and brick, into reusable aggregates, supporting sustainable building practices.


3. Recycling & Waste Management

Jaw Crusher Parts efficiently crush industrial waste like slag, fly ash, and municipal solid waste (MSW) during pre-processing for recycling. Their robust design handles contaminated materials with foreign objects, thanks to the overload protection system, making them reliable choice for waste-to-energy plants and scrap processing facilities.


4. Industrial Minerals Processing

For soft to medium-hard minerals like limestone, dolomite, and gypsum, these parts deliver consistent crushing performance for applications such as cement production, fertilizer manufacturing, and glass-making. The precise control over particle size ensures compliance with strict industry standards for mineral powder and granular products.
