LIMESTONE PRODUCTION LINE line is a production line specially used to crush large limestone raw materials into the required particle size. It is widely applied in building materials, metallurgy, chemical industry, highway construction and other fields. The following is a general introduction to its core components and process flow:
 

I. Main Equipment of the Limestone Production Line

l Vibrating feeder

Function: Feed limestone raw materials into the primary crusher evenly and continuously to avoid blockage.

Features: Adjustable feeding amount, wear-resistant lining design.
 

l Jaw crusher (coarse crushing)

Function: Crushing large limestone (≤1200mm) into medium particle size (about 100-300mm).

Advantages: Simple structure, strong processing capacity, suitable for high hardness materials.
 

l Impact crusher/cone crusher (medium and fine crushing)

Impact crusher: suitable for medium and low hardness limestone, good finished product particle shape, slightly higher powder content.

Cone crusher: suitable for high hardness or high output requirements, strong wear resistance, low energy consumption.

Discharge particle size: usually adjusted to 20-50mm.
 

l Vibrating screen

Function: Screen the crushed materials, qualified particle size enters the next stage, and oversize particle size returns to the crusher (closed loop).

Configuration: Multi-layer screen, graded as needed (such as 0-5mm, 5-10mm, 10-20mm, etc.).
 

l Belt conveyor

Function: Connect various equipment to realize automatic material transmission.
 

l Dust removal system

Function: Reduce dust pollution during the crushing process and meet environmental protection requirements (such as pulse bag dust collector).
 

2. Typical process flow of limestone production line

l Feeding stage

The limestone raw material is fed into the vibrating feeder to remove impurities such as soil.
 

l Coarse crushing stage

The jaw crusher performs the first crushing, and the discharge particle size is ≤300mm.
 

l Medium and fine crushing stage

The impact crusher or cone crusher performs secondary crushing, and the discharge particle size is adjustable (such as ≤30mm).
 

l Screening stage

The vibrating screen is used for classification, and qualified materials enter the finished product pile, while unqualified materials return to the crusher.
 

l Finished product storage

Finished products of different specifications are stored or loaded separately through conveyors.
