The 50-ton/hour (50tph) limestone crushing production line is a small and medium-sized scale and is widely used in building materials, metallurgy, chemical industry and other industries.In order to achieve efficient and stable operation, it is necessary to scientifically select and rationally configure key equipment.
Jaw crushers are generally used in primary crushing equipment.The compressive strength of limestone is moderate (usually 100–200MPa), the jaw breaking structure is simple and easy to maintain, and the bulk limestone above 300mm can be broken to below 100mm to meet the first-level crushing requirements.
Then, according to the particle size requirements of the finished product, it is decided whether to set up a secondary crushing.If the final product requires a particle size of less than 30mm, a counterattack crusher is often configured.Counter-breaking has the advantages of good particle shape and less over-crushing, which is especially suitable for medium-hardness materials such as limestone.
In addition, screening equipment is indispensable.A circular vibrating screen is commonly used to grade the broken materials, and the qualified particle size enters the finished product warehouse, and the over-specification materials can be re-fed to the second break to form a closed-circuit cycle to improve the yield.
The auxiliary system includes a belt conveyor (connected to each host), a dust removal device (to meet environmental protection requirements), and an electronic control system (to achieve centralized control).The entire line should adopt a four—stage layout of “feeding—coarse breaking—fine breaking-screening", with a simple process and a compact footprint.
In summary, a complete set of 50tph limestone crushing line should include: vibrating feeder, jaw crusher, impact crusher, circular vibrating screen, multiple conveyor belts and supporting dust removal and control systems.Reasonable matching of equipment production capacity and power can ensure stable and efficient operation of the system.
