coal grading crusher

Product description

Huashengming’s innovative design makes its （Coal Classification Crusher） coal grading crusher an ideal choice for industries such as coal mining, chemicals, and construction. It excels at crushing raw coal, including gangue, in large coal mines or coal preparation plants. This machine not only crushes but also screens materials, providing dual functionality and offering significant crushing capacity.

Advanced Safety and Reliability Features

Huashengming ensures safe and reliable operation by integrating a limited-distance hydraulic coupler that directly connects the motor to the reducer, effectively preventing power overload. The design also includes sensor overload protection for added safety. Operators can hydraulically adjust the tooth pitch, while the gear roller bearing benefits from centralized lubrication. With optimized tooth shapes focused on shear force, this crusher delivers high efficiency and low energy consumption, resulting in uniform particle output.

Special Cavity and Tooth Shape

Huashengming revolutionizes the traditional double-tooth roller crusher by introducing a design that grades and screens materials through the gaps between teeth, rather than relying solely on impact and extrusion. This special cavity and tooth shape enhance the crusher’s performance, ensuring more precise material processing.

Low-Speed, High-Torque Transmission

The crusher is equipped with a new transmission structure and gear roller design that significantly boosts crushing capacity, automation, and reliability. This low-speed, high-torque transmission system is a key component that enhances overall efficiency.

Multiple Automatic Protection Devices

Huashengming’s coal grading crusher is equipped with various automatic protection devices. These include systems for automatic regular filling of lubricating oil and centralized programming control, ensuring smooth and uninterrupted operations.

coal grading crusher Versatile Applications

This crusher is versatile and can be used to crush a wide range of materials, including surface rocks, coal, limestone, clay ore, iron ore, gold ore, uranium ore, nickel ore, bauxite ore, talc, gypsum, coke, and glass. It is particularly effective in open-pit mining operations.

How It Works: Efficient Crushing Mechanism

The coal grading crusher uses two horizontally mounted and parallel toothed rollers within the crushing chamber. These toothed rollers, equipped with crushing teeth, rotate in unison through a transmission device powered by either a single or dual motor system. This rotation generates a powerful crushing force, breaking down materials at their weak points through impact, shear, and stretching.

Once the material is crushed, the crusher discharges it between the rollers and the comb plates on the side walls. The design ensures that no oversized particles are produced, as materials already meeting the desired size are quickly discharged to avoid unnecessary crushing. This process not only reduces the powder output rate but also boosts overall productivity.

coal grading crusher Performance Advantages

Compact and Efficient Design: The crusher’s small height and structure fit various operational environments perfectly.

Special Gear Structure: The unique gear design handles dry, wet, muddy, and sticky ores without blockages.

High Processing Capacity: The crusher processes up to 14,000t/h, crushing materials with compressive strengths up to 300MPa.

Overload Protection: The hydraulic coupling and electric control prevent damage by stopping and reversing the crusher during overloads.

Ease of Maintenance: The crusher’s design simplifies maintenance, reducing downtime and ensuring long-term reliability.
