Introduction of stone production line
The stone production line is also called gravel production line. It is mainly composed of vibrating feeder, jaw crusher, impact crusher or cone crusher, circular vibrating screen, belt conveyor, centralized electric control, etc. The designed output is generally 50-800t/h, and it can be equipped with other products or tailored according to different processing needs of customers.
Site of stone production line
1. Feeding system
The system feeds the raw materials into the crusher equipment and the screening machine according to the crushing and screening process. The equipment that completes the feeding process has a vibrating feeder or other type of feeding equipment.
2. Crushing system
This system is the heart of the entire set of equipment. Its work is to crush various ore raw materials into finished product with the required particle size. A joint stone production line can be composed of multiple crushers. These crushing machines have different properties and work together to complete the crushing of the stone.

3. The screening conveyor system
The system screens the crushed ore through a screening machine. In the stone composite production line, the sand and stone materials need to be separated, and the graded sand and gravel materials need to be transported to their respective sites. The equipment used in this process is generally a linear vibrating screen or other screening machinery.
Application: The stone production line has been successfully applied to the crushing of limestone, basalt stone, granite, cobblestone and other rocks. The quality of the finished product after crushing has fully met the GB14685-2001 standard, which providing qualified bones for the highway, railway, water conservancy and concrete mixing stations.
Widely application areas
The major equipment of stone production line
1. The hardness of the material does not exceed 320mpa
Such as granite, basalt stone, etc., all of which are applicable to the crushing process of the secondary sandstone production line.
The major equipment including vibrating feeding - jaw crusher (primary crushing) - stone crusher (second crushing such as impact crusher, hammer crusher, and impact sand maker.) - vibrating screen - finished products, in the middle there is a belt conveyor to transfer materials.
Stone production line of the hardness of the material does not exceed 320mpa
2. The hardness of the material does not exceed 150mpa
In order to save customer cost and improve work efficiency, one-time molding equipment is generally used.
The major equipment including vibrating feeding-high-efficiency compound crusher-vibrating screen-finished products, in the middle there is a belt conveyor conveying the material.

Introduction of the major crushing equipment
It is the first step in the crushing stone production line and can be widely used in many sectors such as mining, smelting, building materials, roads, railways, water conservancy and chemical industries, and crushing various materials with compressive strength not exceeding 320 mpa.
It is used for secondary crushing. It can crush all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.) with a feed particle size not exceeding 500mm and compressive strength not exceeding 350mpa. It is widely used in hydropower, highway, artificial sand and gravel, crushing and other industries.
It is also used for second crushing. Suitable for raw materials in metallurgy, construction, road construction, chemical, silicate and other industries, aiming to optimize the crushing materials from coarse to fine to meet the needs of modernization.
It has the characteristics of one-time forming, large crushing ratio, high production capacity and uniform product size. It is one of the major equipment for crushing limestone, coal or other brittle materials below medium hardness in industrial sectors such as metallurgy, building materials, chemical industry and hydropower.
Mobile crushing station
It has small size, convenient movement, and the characteristics of convenient operation, complete functions and flexible matching. It can directly enter the site during the work process, which greatly saves the installation time and transportation cost of the equipment, and does not need to occupy a large space.

Basic process of stone production line
The large stone material in the stone production line is uniformly sent to the jaw crusher by the vibrating feeding for coarse crushing. The coarsely crushed stone material is sent to the impact crusher by the belt conveyor for further crushing; The stone material is sent to the vibrating screen by the belt conveyor for screening, and several stones of different specifications are screened out. The stone that meets the grain size requirement is sent by the finished belt conveyor to the finished material pile; the stone that does not meet the grain size requirement is returned by the belt conveyor. The material is sent to the impact crusher for re-crushing to form a closed circuit multiple cycles. The finished product size can be combined and graded according to the user's needs. In order to protect the environment, auxiliary dust removal equipment can be equipped.

The configuration of the stone production line
Take the limestone as an example
The equipment frequently arranged in the limestone crushing production line including vibrating feeder, jaw crusher, impact crusher, vibrating screen and other equipment. Let's take a closer look:
1. Feeding equipment
The main function is to uniformly feed large pieces of limestone from the silo into the receiving device for further processing. It has the characteristics of stable operation and continuous operation.
2. Jaw crusher
The jaw crusher is one of the indispensable crushing equipment in the limestone crushing production line. The equipment is mainly used for primary rough crushing processing of large limestone. The structure of the device is simple and reasonable, and it adopts a deep V-crushing cavity type, and the work is reliable. The utility model has the advantages of large processing capacity and crushing ratio, high passing rate and output and strong flexibility, and the inlet and outlet ports can be reasonably adjusted according to the actual production demand of the user, and the adjustment range is wide.
3. Impact crusher
The equipment is designed and developed based on the introduction of foreign new technology and combined with limestone characteristics. The limestone is highly targeted, the structure design is more advanced and novel, the installation operation is simple and convenient, the later maintenance and repair is convenient and fast, and the equipment has less downtime. The utility model has the advantages of high operation efficiency, low energy consumption, large production capacity, excellent granularity of finished materials, and no noise and dust pollution in actual operation, and fully meets the requirements of national environmental protection standards.
4. Vibrating screen
The vibrating screen is a high-efficiency screening equipment in the crushing production line. It has a complete range of models, including linear vibrating screens, circular vibrating screens and high-frequency vibrating screens. Users can use different types according to their own needs. The device has fine screening, high screening efficiency, simple equipment structure, light weight, small volume and convenient installation.
The performance characteristics of stone production line
The performance characteristics of stone production line
- 1. The stone crushing production line has a high degree of automation. The entire line requires no manual operation except for the start up and maintenance of the equipment and daily maintenance.
- 2. The equipment has large crushing ratio, high production efficiency, low operating cost, large processing capacity, high profit, and meets the requirements of national high-speed materials.
