Limestone is an important building material and is widely used in construction and industry. Its processing production line is efficient and stable, including primary, medium and fine crushing and shaping and sand washing steps. Limestone plays an important role in various projects due to its excellent physical properties and efficient processing.

Limestone is a widely distributed sedimentary rock whose main component is calcite and usually exhibits a crystalline structure and layered structure. It has important application value in construction and industry. It is hard and easy to process and is a high-quality raw material for infrastructure construction.

Full analysis of limestone crushing production line

Characteristics of limestone

The compressive strength of limestone ranges from 20 to 120MPa, and the density ranges from 2000 to 2600 kg/m. When clay impurities exceed 3% to 4%, their frost resistance and water resistance will be significantly reduced. Siliceous limestone is favored for its high strength and good durability. Due to its fine texture and strong weathering resistance, limestone is widely used in construction projects, including foundations, exterior walls, bridge piers, steps and pavements.

Limestone processing and production technology

The limestone processing production line designed by Shanghai Shibang is efficient and stable, can give full play to the performance of the equipment, has large production capacity and uniform discharge particle size.

1. Primary crushing

The raw materials are evenly fed into the jaw crusher through the vibrating feeder for primary crushing, and then transported together with the fine materials to the impact crusher through the belt conveyor.

2. Medium and fine crushing

The coarsely crushed materials are further crushed in the impact crusher and screened by the circular vibrating screen. Qualified materials are graded according to demand and sent to different storage piles via conveyor belts or directly to the construction site.

3. Finely chop and shape

The VSI5X series new sand making machine is used for shaping sand and gravel materials, and combines multiple crushing modes to provide high-quality sand and gravel aggregates for highways, high-rise buildings and other projects.

4. Sand washing finished products

The XSD series sand washing machine effectively cleans the sand-making products to ensure that the quality of the sand and gravel meets the standards.

Practical application cases

A customer has built a well-planned stone plant in Zhejiang, equipped with PE1000*1200 jaw crusher, PFW1315III hydraulic impact crusher and VSI1140 high-efficiency sand making machine. The production line is capable of processing limestone and providing finished sand to local large-scale mixing stations to meet market demand.

Equipment advantages

Jaw crusher: High compressive strength and excellent crushing ratio, suitable for primary crushing of bulk materials.

Hydraulic impact crusher: heavy-duty design and high yield, supporting rapid adjustment of discharging particle size.

High-efficiency sand making machine: uniform particle size, excellent product shape, suitable for artificial sand making and stone shaping.

As an important source of building materials, limestone plays an indispensable role in various projects due to its efficient processing and excellent physical properties.
