Limestone is widely used in the construction industry due to its performance. Common crushing equipment includes jaw, impact and impact crushers, which are used for coarse crushing, medium crushing and fine crushing respectively. The production line requires multiple equipment to cooperate, and the equipment selection and configuration affect the benefits. It is critical to choose the right equipment manufacturer.

As a common building and industrial raw material, limestone is widely used because of its good thermal conductivity, firmness, water absorption and sound insulation. The profit margin of limestone processing plants has attracted the attention of many investors. So, what are the common limestone crushing equipment? What is the crushing process?

Common limestone crushing equipment

Jaw crusher (coarse crushing)

The jaw crusher is vividly called "tiger mouth" because of its large feed inlet and deep crushing cavity. It has a simple structure, easy operation and good environmental performance. It is mainly used in the coarse crushing of limestone.

Impact crusher (medium crushing)

The impact crusher is often paired with a jaw crusher for secondary medium and fine crushing. Its rotor runs at high speed and has a large crushing ratio, which is very suitable for crushing soft materials such as limestone. The finished particles are in good shape and cubic, with high comprehensive benefits.

Impact crusher (fine crushing)

The impact crusher, also known as a sand making machine, is a new type of intelligent fine crushing equipment. It can process stones with a particle size of no more than 65mm into sand and gravel of 0-5mm. The sand and gravel produced have uniform particle size and reasonable gradation, meet the standards for building sand, and have excellent quality.

Limestone crushing process flow

From raw stone to finished stone, the complete limestone crushing process usually requires the cooperation of multiple equipment. The following is a common limestone crushing production line process:

Coarse crushing

Large pieces of limestone are evenly fed into the jaw crusher by a vibrating feeder for coarse crushing, and the coarsely crushed materials are screened and enter the next step.

Medium crushing

The coarsely crushed limestone gravel enters the impact crusher for medium crushing. This step can effectively improve the crushing ratio and make the finished particle shape more regular.

Fine crushing and sand making

The medium-crushed materials enter the impact crusher for fine crushing and sand making. Through vibration screening, the finished materials that meet the requirements are sent to the silo, and those that do not meet the requirements are returned to the crusher for further processing.

Equipment selection and production line configuration

Configuring a complete limestone crushing production line requires consideration of multiple factors, such as ore particle size, output requirements, finished product particle size requirements, etc. Common equipment includes jaw crushers, impact crushers, impact crushers, vibrating screens, feeders and conveyor belts. Depending on different needs, the total investment in the crushing line ranges from hundreds of thousands to millions.

It is crucial to choose the right equipment manufacturer

When choosing limestone crushing equipment, it is crucial to choose a strong equipment manufacturer. Strong production strength not only ensures equipment quality, but also provides comprehensive after-sales service. It is recommended that investors visit the manufacturer on site before purchasing equipment to ensure that the selected equipment can meet actual production needs, help quickly put into production and realize profits.

By reasonably configuring equipment and optimizing production processes, limestone crushing and processing plants can achieve efficient production and bring considerable economic benefits to investors.
