Impact crusher is a highly efficient crushing equipment, mainly used for medium and fine crushing of various ores and rocks. Its working principle is to use blowbar on the high-speed rotating rotor to break the material entering the crushing chamber, so that it collides with the impact plate and the wall, thereby achieving material crushing. In limestone crushing process, the impact crusher has the advantages of large crushing ratio, uniform product particle size, less over-crushing phenomenon, and low energy consumption.
Common types and characteristics of impact crushers
Simple structure: It consists of main components such as rotor, impact plate, and crushing chamber. The structure is relatively simple and easy to maintain.
High crushing efficiency: The high-speed rotating rotor drives the plate hammer to hit the material, which can achieve efficient crushing operations and is suitable for crushing limestone below medium hardness.
Adjustable product particle size: The particle size of the product can be adjusted by adjusting the gap between the impact plate and the rotor to meet different production needs.
Higher crushing ratio: With two rotors, the material is crushed twice in the crushing chamber, with a higher crushing ratio, and the limestone can be crushed finer.
Strong production capacity: The double-rotor design greatly improves the processing capacity of the equipment, which is suitable for large-scale limestone crushing production lines.
More uniform product particle size: After two crushing and impact, the particle size of the product is more uniform, which can better meet the requirements of high-quality limestone products.
Single-stage crushing: It combines the advantages of impact crushing and hammer crushing, and can achieve single-stage crushing of limestone, reducing the crushing process, equipment investment and operating costs.
High-chromium plate hammer: The use of high-chromium plate hammer and other high-quality wear-resistant materials increases the service life of the plate hammer and reduces the replacement frequency and cost of wearing parts.
High degree of automation: Equipped with advanced automation control system, it can realize remote monitoring, fault diagnosis and other functions, and improve production stability and efficiency.
Considerations for selecting impact crusher
1.Production capacity: According to the scale and output requirements of the limestone crushing project, select an impact crusher with appropriate production capacity. Generally speaking, large limestone mines or cement plants need to process a large amount of limestone, and should choose a dual-rotor or new single-stage impact crusher with large production capacity; while small processing plants can choose a single-rotor impact crusher.
2.Material properties: The hardness, humidity, particle size and other characteristics of limestone will affect the selection of impact crusher. For limestone with higher hardness, equipment with more wear-resistant materials for hammers and impact plates should be selected; for limestone with higher humidity, the discharge performance of the equipment should be considered to prevent material blockage.
3.Product particle size requirements: If the particle size of the product after limestone crushing is required to be fine and uniform, such as for the production of high-end building materials or chemical raw materials, a dual-rotor impact crusher or a new single-stage impact crusher can be selected. They can better control the product particle size and produce fine-grained products that meet the requirements.
4.Investment cost and operating cost: The prices of impact crushers of different types and specifications are different. Choose the appropriate equipment according to the investment budget of the project. At the same time, the operating cost of the equipment should also be considered, including energy consumption, replacement cost of wearing parts, maintenance cost, etc. Generally speaking, although the investment cost of the new single-stage impact crusher is relatively high, it may have better economy in long-term operation due to its high efficiency, energy saving and low maintenance cost.
People Also Frequently Asked For - FAQ
1. What is the best crusher for limestone?
Jaw crushers are workhorse crushers and the most commonly used. They're fit for abrasive material as well but are far more portable than gyratory crushers and can be relocated each year as necessary. Impact crushers are best for less abrasive material, like limestone.
2. Is limestone hard to crush?
Limestone is an easy to crush sedimentary rock that is a soft to medium-hard. Crushed limestone has a variety of uses from dense graded aggregates (DGA) to aggregates for concrete and asphalt materials.
3. What crushers are used in limestone mines?
The ideal limestone crusher on the market are limestone jaw crusher, limestone impact crusher, limestone cone crusher, limestone sand making machine, limestone mobile crusher.
