According to different production processes and material characteristics, various crushing equipment and screening equipment can be flexibly combined to meet diversified production needs and achieve personalized production solutions.
Working Principle
The materials are orderly conveyed into the crusher by the feeding equipment. The crusher uses various crushing methods such as extrusion, impact, and grinding to decompose the materials into smaller particles in terms of grain size. The crushed materials are transported to the vibrating screen by the conveyor for classification and screening. The materials that do not meet the grain size standard will be sent back to the crusher by the conveyor for secondary crushing. Such a process repeats cyclically to form a closed loop until the materials reach the set grain size specification. The qualified finished materials are finally output by the conveyor.
Application Areas
Mining Exploitation
In various mining exploitation scenarios, it can crush ores of different hardness levels on-site, such as gold mines, silver mines, lead-zinc mines, etc., reducing the transportation cost of ores and improving the mining efficiency.
Tunnel Engineering
It is used for the crushing treatment of rock waste generated during tunnel construction. The waste is processed into reusable aggregates to achieve the recycling of resources, and it also helps to keep the construction site clean and tidy.
Open-pit Coal Mines
It can conduct preliminary crushing of coal at the coal mining site, making it convenient for subsequent transportation and processing, and improving the overall efficiency of coal mining.
Construction Waste Treatment
It can flexibly enter urban construction waste storage sites, crush and screen concrete blocks, waste bricks, stones, etc., and produce recycled aggregates for use in road base laying, filling projects, etc.
Component Composition of Track-Mounted Mobile Crushing Stations
Track-mounted mobile crushing stations are highly efficient and versatile equipment, commonly used across diverse complex environments and operational scenarios. Their intricate and precision-engineered structure relies on the coordinated operation of multiple critical components to ensure stable performance and accomplish various tasks.
The Travel System Is The Key To The Flexible Mobility Of Tracked Mobile Stations, Primarily Consisting Of Track Assemblies, Drive Wheels, Idler Wheels, Track Rollers, And Tensioning Devices.
1. Track Assembly: As the core component, it forms a flexible chain link with track plates and track pins. It offers excellent adhesion and wear resistance, providing sufficient traction across various terrains to ensure stable movement of the equipment.
2. Drive Wheels: Responsible for power transmission, typically driven by hydraulic motors or engines. Rotation propels the tracks forward or backward. Designed for high strength and wear resistance to withstand harsh environments.
3. Idler Wheels: Mounted at the front of the tracks, these guide direction. Adjusting their position and angle enables precise control of the unit's travel path.
4. Idler Wheels: Support the entire machine's weight while rolling with the tracks. Designed for high load-bearing capacity and wear resistance to ensure stable operation during prolonged use.
5. Tensioning System: Adjusts track tension to maintain optimal running tension. Typically driven by springs or hydraulic systems, allowing real-time adjustments based on operational conditions.
Drive System
The drive system serves as the power source for the tracked mobile station, primarily consisting of an engine, hydraulic motor, reducer, and drive shaft, responsible for supplying energy to the equipment.
1. Engine: As the core power source, either diesel or electric variants can be selected based on operational requirements. Diesel engines offer high power and fuel efficiency, making them suitable for heavy loads and extended operation. Electric engines are environmentally friendly and quieter, better suited for scenarios with stringent environmental requirements.
2. Hydraulic Motor: Specifically powers the drive wheels, utilizing the hydraulic system to rotate them. It is compact, lightweight, yet powerful, capable of adapting to complex environments.
3. Gearbox: Reduces the hydraulic motor's rotational speed while increasing output torque to precisely meet the drive wheels' requirements. Its design emphasizes load-bearing capacity and transmission efficiency, ensuring stable operation and high productivity.
4. Drive Shaft: Transfers power from the engine to the hydraulic motor and drive wheels, facilitating power distribution. Engineered for strength and durability, it reliably withstands harsh operating conditions.
The Control System Serves As The "Nerve Center" Of The Tracked Mobile Station, Responsible For Remotely Operating The Equipment. It Primarily Consists Of Joysticks, Brake Pedals, And Various Switches.
1. Joystick: Controls the direction and speed of the equipment. Moving it up, down, left, or right enables precise control, making operation highly intuitive.
2. Brake Pedal: Controls the braking system for emergency stops or deceleration. Designed for both comfort and reliability, it enables rapid response in critical situations.
3. Various Switches: Manage equipment functions such as start/stop, lighting activation, and audio system operation. Emphasizing ease of use and safety, they ensure stable and reliable equipment performance.
Suspension System
The suspension system primarily supports the equipment while absorbing shocks and vibrations encountered during operation, ensuring smoother running and easier handling. Its core components are the suspension mounts and suspension springs.
1. Suspension Mounts: One end connects to the equipment body, while the other attaches to the suspension springs, providing support and stability. Design focuses on load-bearing capacity and stability to prevent equipment sway during operation.
2. Suspension Springs: These absorb and cushion impacts and vibrations during operation, enhancing equipment stability and comfort. Spring selection requires consideration of stiffness and damping characteristics to suit diverse operational environments and requirements.
The Load-Bearing System Supports The Main Body And Various Attachments Of The Tracked Mobile Station, Serving As The Key To Stable And Reliable Operation. It Primarily Consists Of The Platform Structure And Load-Bearing Supports.
1. Platform Structure: As the main framework of the equipment, it mounts various devices and attachments. Design must prioritize load capacity and stability to ensure operational steadiness.
2. Load-bearing Supports: Specialized components for securing and supporting diverse equipment and attachments, preventing detachment or damage during operations. Design emphasizes load-bearing strength and reliability, adaptable to varying operational requirements and scenarios.
FAQ
Q: Why did the equipment suddenly shut down?
A: Possible causes include:
V-belt too loose causing slippage;
Improper feed size or speed leading to blockage;
Insufficient pressure to drive material;
Eccentric shaft jammed or bearing failure.
Q: How to increase the production capacity of a tracked mobile jaw crusher?
A: Strictly control feed size and volume to synchronize feeding rhythm with the crusher's processing cycle. Adjust the feeder angle for pre-screening, then optimize the jaw crusher's discharge opening and attack angle.
Q: What are the disadvantages of tracked mobile crushing plants?
A: Initial investment is higher than fixed crushers. Fuel consumption increases in complex operating conditions. Long-term processing of ultra-hard materials may accelerate equipment wear.
