Limestone mainly composed of calcium carbonate is used in large quantities as building materials and industrial raw materials. It has high application value and the profitability of processing plants is also very objective. Especially in recent years, various fields have developed rapidly and demand continues to rise. However, what equipment is good for crushing limestone? How much is the price? This article answers in detail, and attaches the production line process flow for reference. What equipment is good for crushing limestone?

The structure of limestone is relatively complex, with Mohs hardness of level 3 and brittle nature. It can be directly processed into stone and burned into quicklime. Generally, jaw crushers, impact crushers, hammer crushers are recommended, because they can meet both industry standards and customer needs.

Jaw Crusher

The particle size is less than or equal to 1200mm to be crushed to 10-350mm. It is generally used for coarse crushing. Its crushing cavity is deep and there is no dead zone. There is no need to worry about blockage, even fed large size raw materials. The wedge adjusts the discharge port to reduce the labor intensity and the downtime. Uniform particle size are helpful for the second-stage crushing treatment. Coupled with the optimization of the motion parameters and the large crushing ratio, it is very suitable for crushing large pieces of limestone.

Impact Crusher

The particle size is less than or equal to 800mm and is crushed to 5-60mm. It is generally used for the second crushing. The material is crushed by impact. The crushing is repeated between the hammer and the impact plate. The new structure design, the machine has strong rigidity and the rotor has a large moment of inertia. The finished product has good grain shape, cubic shape, no tension and cracks, and high comprehensive benefit.

Hammer crusher

Particle size ≤1000mm can be directly crushed to 5-60mm, and the hammer crusher can crushed raw material into final shape at one time and the finished product has a good shape. It is set without screen bottom, which is not easy to stick in the crushing cavity and avoids clogging. It is very suitable for processing such materials with high humidity and discharging. The particle size can be adjusted freely, and the hammer head is made of wear-resistant materials such as high soldering iron, which is more sturdy and durable, prolongs the service life, and reduces maintenance costs.

Limestone crushing production line technological process The processing of limestone into stone generally requires processes such as coarse crushing, medium and fine crushing, and screening. The particle size of raw materials, output requirements, budget, finished products, site, etc. must also be considered. Here is a technical manager who provides common configuration solutions for reference.

Solution one

Material pile→vibrating feeder→jaw crusher→impact crusher→vibrating screen→qualified material→belt conveyor→stock bin stacking.

Solution two

Material pile→vibrating feeder→hammer crusher→belt conveyor→vibrating screen→qualified material.

How much does the limestone crusher cost?

I learned from the above that there are many kinds of limestone crusher equipment, and the effects of each type are slightly different. The price is generally about tens of thousands to hundreds of thousands, and if a full set of production line equipment is configured, the price is different. Whats more, there are differences in selection, workmanship, and sales methods, so prices are unstable.
