Tongli Cone crusher Introduction

A cone crusher is a type of crusher that breaks rock by squeezing it between an eccentrically gyrating spindle and a concave hopper. The spindle is covered by a wear-resistant mantle and the hopper is covered by a manganese concave or bowl liner. The rock enters the top of the cone crusher and becomes wedged and squeezed between the mantle and the bowl liner, resulting in size reduction. Cone crushers are used for various applications, such as mining, construction, recycling, and more. They can process and reduce different types of materials, such as aggregates and ores. Cone crushers offer many benefits, such as high crushing efficiency, adjustable discharge settings, ease of maintenance and operation, durability, and cost-effectiveness.

Tongli cone crusher structure

Tongli cone crushers feature strong and reliable main frames, mantles, concaves, and eccentric assemblies that deliver superior performance and reliability. Our cone crushers can meet your various crushing needs and help you achieve your goals.

Main Frame: The main frame of a cone crusher is the foundational structure that supports all other components. Its robust construction ensures stability and durability during operation. The frame’s design withstands the high forces generated by crushing, maintaining the crusher’s integrity. It also provides a platform for other components to be securely mounted, simplifying maintenance and ensuring long-term reliability.

Mantle: The mantle is a key wear component that covers the cone’s central portion. Its primary function is to crush the incoming material against the concave, breaking it down into finer particles. Made from durable materials, the mantle withstands continuous abrasion and impact. A well-maintained mantle guarantees consistent product size and shape, optimizing the crusher’s efficiency and performance.

Concave/Bowl Liner: The concave, also known as the bowl liner, is the stationary surface against which the mantle crushes material. Its unique shape directs the material towards the crushing chamber for efficient reduction. Crafted from wear-resistant materials, the concave endures abrasion and impact, ensuring its durability and longevity. An appropriately fitted and maintained concave improves the crusher’s capacity and minimizes wear on other components, maintaining efficient crushing operations.

Eccentric Assembly: The eccentric assembly consists of an eccentric shaft, eccentric bushing, and other related parts. It imparts the gyratory motion to the main shaft, causing the mantle to move in a circular path. This motion generates the crushing action necessary to break down material. Properly functioning eccentric assembly ensures smooth and efficient operation. Regular maintenance and proper lubrication of its components are essential to maintain optimal performance and extend the crusher’s lifespan.

Bowl Assembly: The bowl assembly houses the concave and provides a secure mounting for it. It also contains the adjustment ring that controls the crusher’s discharge setting. The ability to adjust the discharge setting allows for the production of various particle sizes. The bowl assembly’s sturdy construction and precise design enable consistent and accurate adjustments, contributing to the crusher’s versatility and adaptability.

Feed Hopper: The feed hopper is the entry point for material into the crusher’s crushing chamber. It ensures a consistent and controlled flow of material to prevent overloading and ensure efficient crushing. The hopper’s design minimizes spillage and blockages, improving overall throughput. Its strategic placement and design are crucial in maintaining a steady supply of material, optimizing the crusher’s performance and productivity.

Tongli Cone crusher design principle

Versatile Crushing Capability: Tongli cone crushers offer versatility in crushing various types of materials, from hard and abrasive rocks to soft and less abrasive ones. This adaptability makes them suitable for a wide range of applications across industries such as mining, construction, and aggregates. The ability to process different materials effectively enhances their utility and value in diverse settings.

Efficient Particle Size Reduction: Tongli cone crushers excel at producing uniform particle sizes through a combination of compression and impact forces. As material is fed into the crushing chamber, it’s gradually compressed between the mantle and concave, resulting in finer particles. This efficient reduction process delivers consistent end-product sizes, ensuring the production of high-quality aggregates and optimized downstream processes.

Consistent Product Shape: The design of Tongli cone crushers promotes a well-defined and consistent product shape. The concave’s curved profile and the mantle’s gyratory motion contribute to producing cubical and uniform particles. This aspect is especially crucial in applications where precise particle shape is essential, such as in concrete production or road construction, as it enhances the final product’s performance and aesthetics.

High Crushing Efficiency: Tongli Cone crushers are engineered for efficient crushing by utilizing the principle of inter-particle crushing, where particles are broken between two crushing surfaces. This results in a higher crushing ratio and better utilization of input energy, leading to enhanced crushing efficiency. High efficiency translates into reduced operating costs and improved overall productivity.

Adjustable Discharge Setting: The adjustable discharge setting of Tongli cone crushers allows operators to control the product size and shape according to specific requirements. By regulating the distance between the mantle and concave, operators can produce a range of desired end-product sizes. This feature also enables operators to adapt to changing conditions and requirements, such as different feed materials or output demands, ensuring optimal performance and flexibility.

Reliable Operation and Low Maintenance: Tongli Cone crushers are designed for reliable and durable operation. With fewer moving parts than other crushers, they have less wear and tear and fewer chances of failure. This simplicity reduces maintenance needs and downtime. Their robust design and quality manufacturing ensure their long service life and consistent performance.

Industry Knowledge extension

How does a cone crusher differ from other types of crushers in terms of design and operation?

A cone crusher is a type of crusher that has a unique design and operation compared to other types of crushers. Unlike other crushers that use impact, shear, or attrition to break down material, a cone crusher uses compression to crush material by applying force between a rotating cone-shaped mantle and a stationary concave bowl. The cone crusher has a vertical axis and a horizontal base, and the mantle is mounted on the top of the axis and can rotate and gyrate around it. The bowl is fixed to the base and has an inverted cone shape that matches the mantle. The material is fed into the top of the crusher and falls into the gap between the mantle and the bowl. As the mantle rotates and gyrates, it squeezes the material against the bowl, creating smaller and finer output as the gap narrows. The output size can be adjusted by changing the gap width, which can be done by hydraulic or mechanical means. The cone crusher can operate in different modes, such as open circuit, closed circuit, or interlocked, depending on the desired product quality and quantity.

What are some of the factors that affect the performance of a cone crusher?

The performance of a cone crusher depends on several factors, such as the feed characteristics, the crusher settings, the wear and tear of the cone and the bowl liners, and the environmental conditions. To optimize the performance of a cone crusher, one should choose the right feed size and type, adjust the crusher settings to achieve the desired product size and shape, replace or repair the worn or damaged liners regularly, and perform regular inspections and maintenance.
