Wide application of limestone crusher plant
Stone crushing production line is applied to the crushing and processing of limestone, basalt, granite, pebbles and other rocks. The quality of the finished product completely meets the construction standards, which provides qualified aggregate for highway, railway, water conservancy, concrete batching plant and other industries.
The working process
The crushing plant process includes: silo-vibrating feeder-jaw crusher-impact crusher-circular vibrating screen-final product
First primary crushing
The limestone of the original material passes through the silo, it is uniformly fed by the vibrating feeder, and transported to the jaw crusher for primary crushing. The material after the primary crushing and the fine material screened by the vibrating feeder are transported to the compact crusher together with the belt conveyor.
Medium crushing and fine crushing
After the rough crushing, material transported to the impact crusher is crushed, the limestone after impact crusher and crushing is screened by circular vibrating screen: the larger particle limestone is returned to the impact crusher and crush again.
Final product
And the grain size qualified material is graded according to the demand and transmitted by the belt conveyor to the stock piles or transported directly to the construction site by the truck.
Advantages of limestone crusher plant
- Good grain shape of final product
Most of the finished limestone particles treated by the crushing production line are cubes, which is helpful to deep processing limestone in the later stage.
- Scientific and simple technological process
The process flow of the production line is simple, scientific and reasonable, smooth operation.
- Reasonable and suitable equipment configuration
The complete equipment configuration, and equipment collocation of limestone crushing production line are reasonable, which is beneficial to limestone crushing.
- Less pollution, less noise
Lime stone crushing production line is equipped with high-tech sealing device, resulting less dust pollution, less noise and good environmental protection performance.
Crushers of limestone crushing plant
Primary rough-crushing: jaw crusher
Feed particle size: ≤1500mm
Processing capacity: 1-2200t/h
Features: simple structure, compact layout, large crushing ratio, uniform grain shape, simple operation, convenient and fast maintenance, strong treatment capacity, high production capacity.
Jaw crusher is widely used in mine, metallurgy, building materials, highway, railway, water conservancy and chemical industry.
Secondary crushing: impact crusher or cone crusher
Impact crusher:
Feed particle size: ≤800mm
Processing capacity: 30-800t/h
Features: The structural design is unique, the control-ability and flexibility are strong, the discharged particle size can be adjusted reasonably, the grain shape of finished product is better, and the comprehensive economic benefit is high.
The plate hammer of impact crusher is easy to wear, it is also limited in the application of hard material crushing. Impact crusher is usually used for rough crushing, medium crushing and fine crushing limestone, quartz, dolomite, iron sulfide other medium hard brittle material.
Different types of cone crusher:
Hammer crusher
Hammer crusher is kind of new crushing device. It is designed, optimized and produced based on common hammer crusher, impact crusher, vertical hammer crusher and mechanical principles of hammer head/board hammer on the stone to crush. It changes the method of controlling the particle size with grid section, reduces the wear of hammer in the crushing cavity, prolongs the service life of hammer by 4-6 times, achieves great breakthrough of crushing technology and the effect of getting twice the result with half the effort.
Hammer crusher has the advantages of large feeding particle size, small discharge particle size, turns three-stage crushing into first-order crushing, which completely realizes the low-cost operation of one crusher instead of two crusher pieces. As a result, the cost can be reduced by 35%. It is equipment with low energy consumption and low investment. It can crush wet material, that is, water can be added when crushing wet material to reduce dust pollution and protect workers’ health and environment.
Why choose AIMIX equipment?
Low operation cost: the whole limestone crushing production line doesn’t need much labor. Automation degree is high, and the operation cost is low.
Low investment cost: for purchasing a whole set of crushing plant, the crushing efficiency is high, preferential treatment is great, and the investment recovery cycle is short.
High profit: the final product produced by limestone crusher plant is matched with the market demand, and the market demand is large, which is beneficial for clients to get high profit.
