Whether a gravel yard operates efficiently depends mainly on whether the matching production line is scientific and reasonable.
In actual production, the main function of any ore crushing production line is to crush various ores, gravel, etc. to a reasonable particle size and shape. Since there are many devices that make up an ore-crushing production line, and the functions of each other are intertwined, it is not a matter of forcing a scientific production line. The production line must be tailored according to the material conditions, output requirements, finished product requirements and other conditions. The purpose is to save trouble and effort.
STLT Mobile Stone Crushing Plant Solution
A key advantage of mobile crushing plants is their environmental friendliness and elimination of the need for installation and foundation, which makes them highly efficient for processing a wide range of materials such as limestone, basalt, pebbles, iron ore, and construction waste.
Moreover, mobile crushers contribute significantly to quarrying efficiency and safety by allowing on-site material processing and reducing the need for extensive material transportation.
Our crushing plant is an entire production line composed of different equipment such as jaw crusher, cone crusher, sand making machine, sand washing machine, vibrating screen, and belt conveyor.
Note:We have both mobile stone crusher plant and stationary crushing line. According to the specific needs of different customers, we can customize personalized production line configurations.
Crushing Combination Solutions for Different Stone Materials
Before configuring the crushing and sand making production line, we must first figure out the raw materials that need to be crushed, such as its size, hardness, humidity, etc.
In addition, we must clarify our own requirements for output and finished product particle size and type. This will provide the necessary scientific basis for the later configuration of suitable types of crushers and sand making machines.
For example, if a hammer crusher is selected for hard rock, the direct consequence is that the hammer head will wear out quickly and the cost of replacing accessories will be high; and the disadvantage of choosing a cone crusher for soft rock is the high cost of equipment investment and subsequent maintenance.
Solution for stone production line and sand making line
The common configuration of a complete stone production line generally uses two-stageand three-stage crushing pro sses. Most
gravel plants usually use two closed-circuit process, that is, the secondary crusher and the screening equipment form a closed
circuit, ensuring that the product size can meet the requirements of sand and gravel aggregate.
The general configurations of the equipment are as follows.
- Vibrating feeder+ jaw crusher+ impact crusher+ belt conveyor+circular vibrating screen:
2.Vibrating feeder+ jaw crusher+ cone crusher+ belt conveyor+vibrating screen; - Vibrating feeder+ jaw crusher+ impact crusher+sand making machine+belt conveyor+circular vibrating screen
Sand making production line consists of a vibrating feeder, a Jaw Crusher, a Cone Crusher, an Impact Crusher (sand-maker), a vibrating screen, sand washer (sand classifier), a belt conveyor, a water treatment system and centralized electronic control system. We could also add a dust separator to the line to meet the specific requirements of our clients. We could assemble the production line according to the requirements of various processes to ensure the line has the best performance.
Solution for soft and less abrasive sand and gravel aggregates
Generally, it is divided into feeding, crushing, screening and conveying. The raw materials are conveyed to the vibrating feeder through the silo, and then conveyed to the first crushing equipment for coarse crushing by the vibrating feeder. The crushed materials are conveyed to the second crushing equipment (fine crushing) by the belt conveyor.
After crushing, the materials are conveyed to the circular vibrating screen for screening by the belt conveyor. The materials larger than the required size are returned to the second crushing for further crushing. The materials screened by the circular vibrating screen are finished materials.
If the particle shape is not good enough, you can add a vertical shaft impact sand-making machine for shaping. In this way, the particle shape of the crushed materials will be more rounded and the effect will be better.
Solution for hard and highly abrasive sand and gravel aggregates
Large hard rock materials are fed evenly to the vibrating feeder through the silo, and then enter the jaw crusher for the first crushing.
The coarsely crushed materials are screened by the vibrating screen as required and then conveyed by the belt conveyor to the cone crusher for the second medium and fine crushing.
After medium and fine crushing, the circular vibrating screen is used for screening, and the larger particles are returned to the cone crusher for crushing again. At this time, the required sand and gravel aggregates can be obtained.
If sand making and shaping are required, the materials that meet the requirements are put into the sand-making machine for further crushing and shaping. If the materials need to be cleaned, a sand washing machine can be added for cleaning. Finally, the materials that meet the requirements are classified and packaged according to different particle size ranges.
Here we take common minerals of quartz, cobblestones, sandstone, granite and limestone as examples to recommend the configuration of sand production line for you.
Quartz
- Mohs hardness: 7-7.5
- Density: 2.64g/cm³-2.71g/cm³
Quartz is a hard, wear-resistant, chemically stable silicate mineral, the main component of which is silicon dioxide. It is an important industrial mineral raw material. Generally, after crushing and sand making, it is used in glass, building materials, ceramics, and even high-tech electronics industries.

Common Crusher Solutions in the Crushing Process
In the crushing process, several types of crushers are commonly used, each designed for specific applications and material types.
Jaw crusher
The jaw crusher is used in the first crushing process of the crushing line, and can crush large particles with a compressive strength of no more than 320MPa into 100mm~300mm.
- Function: Primarily used as a primary crusher to break down large, hard materials.
- Mechanism: Utilizes a movable jaw plate and a fixed jaw plate to crush the material by compressive force.
- Applications: Suitable for crushing ores, minerals, and rocks, often used in mining and aggregate production.
Impact crusher
The impact crusher can generally handle ores or rocks below 500mm and with a compressive strength of up to 350MPa. The crushed materials are cubic particles. The impact crusher is generally used in the second crushing process of the crushing line, and can also be used as the first crushing process for materials with smaller feeds.
- Function: Designed to crush softer materials and produce a high reduction ratio.
- Mechanism: Utilizes high-speed impact forces; material is struck by hammers or blow bars and thrown against an impact plate.
- Applications: Commonly used in construction and demolition, recycling, and road building.
Cone Crusher
The cone crusher uses the principle of laminated crushing to form a protective layer of the material layer. It has the characteristics of reliable structure, high crushing efficiency, convenient adjustment, and economic use. Like the impact crusher, the cone crusher is often used in the second crushing process of the crushing line, and can also be used as the first crushing process for materials with smaller feeds. However, the feed particle size of the cone crusher is generally smaller than that of the impact crusher.
- Function: Typically used for secondary and tertiary crushing.
- Mechanism: Features a rotating cone that crushes materials against a fixed bowl liner through a combination of crushing and grinding.
- Applications: Effective for hard and abrasive materials, widely used in mining, quarrying, and recycling
Hammer Crusher
Hammer crusher has the characteristics of large crushing ratio, high production capacity and uniform product particle size. It is one of the primary equipment for fine crushing of limestone, coal or other brittle materials with medium hardness or below in metallurgy, building materials, chemical industry and hydropower industry.
- Function: Used for crushing and grinding materials into smaller particles.
- Mechanism: Uses rapidly rotating hammers to impact and break the material.
- Applications: Commonly used in the agricultural and recycling sectors for materials like biomass, wood chips, and food products.
Vibrating Screens
In addition to the main crushing equipment, some auxiliary equipment such as vibrating screens, feeders and cVionveyors are also required to complete the configuration and operation of this production line.
- Function: Used to separate materials by size, ensuring that only appropriately sized materials proceed to the next stage of processing.
- Applications: Essential for preparing feeds for crushers and ensuring consistent output grades.

Stationary Crushing Plant Equipment Solutions
Fixed crushing production lines have a long service life, mature and stable technology, and most mines have fixed crushing stations. A fixed crushing station is a crushing production line that installs crushing equipment at a suitable site and cannot be moved after a one-time installation.
Semi-stationary Crushing Plant
Semi-fixed crushing station is a transitional mode from semi-mobile crushing station to fixed crushing station. From the connection with the ground, the crushing machine frame has a solid connection with the ground (anchor piles can be used in bedrock areas, and reinforced concrete foundations can be used in loose areas).
From the layout position, it is generally fixed on the fixed side of the mining site to reduce the frequency of relocation as much as possible and increase the service life, which is particularly important for rock crushing and transportation.
When a semi-fixed crushing station is relocated, only the equipment body connected to the foundation with bolts can be disassembled and moved for reuse, and the foundation buried below the surface is discarded.
Advantages: Because the semi-fixed crushing station has a solid foundation, it can be large-scale when selecting a model. It is suitable for mines with large processing capacity and has a long service cycle.
Disadvantages: It is necessary to build a fixed foundation, the construction period is long, the relocation project is large, the relocation operation time is long, and the civil engineering cost is high.
Station de concassage
Fixed crushing stations are usually arranged outside the boundary of the stope, or set up inside the stope and combined with the chute. They are not affected by the advancement and deepening of the stope steps, and are connected to the ground with a permanent fixed foundation.
After they are built, they are used permanently and will not be moved. There are various feeding methods, such as direct unloading by cars or feeding by ore discharge devices with buffer silos. Fixed crushing stations are generally located in the crushing workshop of the ore dressing plant and have the same service life as the mine.
Disadvantages: Its biggest disadvantages are long ore transportation distance, high transportation cost, and difficulty in reasonable adjustment.
Mobile Crushing Plant Equipment Solutions
Mobile crushing stations generally integrate feeding, crushing and conveying. They are moved by crawler or tire type (there are also walking type), and can adjust their position at any time in the mining site as the working surface moves.
Replace dump trucks, reduce procurement costs; reduce transportation costs by 50% to 70%; reduce spare parts costs; reduce labor costs; reduce pit road maintenance; and have the characteristics of safety and environmental protection.
Because it is a three-in-one device, and the continuous transportation equipment connected to it is a belt conveyor, the crawler mobile crushing station is more suitable for large-scale open-pit mines and is suitable for large-scale, continuous mining processes.

Wheeled Mobile Crushing Plant
The tire or wheeled type is moved by the front of the vehicle and needs to be towed by a truck when traveling on the road. It is generally used to process construction waste in urban areas, or in processing sites with strong mobility and the need to frequently change the work site. The machine needs to travel on a flat road, but the requirement for the site area is not high.
The integrated unit equipment installation form eliminates the complicated site infrastructure installation work of the separate components, reduces the consumption of materials and man-hours, and is a production line that integrates process equipment such as receiving, crushing, and conveying. The unit’s reasonable and compact spatial layout improves the flexibility of site deployment.
Crawler/Tacked Mobile Crushing Plant
Crawler type crusher is a fully automatic type. The crawler is driven by a hydraulic system and can be put into operation by remote control, which has a higher degree of automation.
Because the crawler has strong grip and the machine body is heavy, it can travel on hillsides and rugged roads. Therefore, this machine is often used for climbing operations and crushing operations in mountainous or uneven work sites.
According to the actual production requirements, corresponding equipment is equipped and various combinations can be made to form a “crushing before screening” or a “screening before crushing” process.
It can be combined into a two-stage crushing and screening system of coarse crushing and fine crushing, or a three-stage crushing and screening system of coarse crushing, medium crushing and fine crushing. It can also operate independently, which has great flexibility.

Mobility
The wheel-type mobile crushing station cannot be fully classified as a mobile crusher because its movement relies on being towed by a semi-trailer. Therefore, in terms of mobility, it is not as effective as the track-type mobile crusher, which is self-driven by hydraulic power.
Applicable Sites
Due to the fact that the wheel-type mobile crushing station is towed by a vehicle, it is more suitable for various applications in industries such as construction waste treatment, earth and stone projects, urban infrastructure, road construction, and construction in general, where a variety of sand and gravel materials need to be crushed.
The track-type mobile crusher features a chassis with a fully rigid boat-shaped design. It has high strength and low ground pressure, providing good adaptability to hilly and wetland environments, even enabling slope operations. Therefore, it is commonly used in harsh operational environments like mining and open-pit coal mining.
However, due to its convenient and fast mobility, it is increasingly used for processing urban construction waste, and many manufacturers now focus on producing track-type machines.
Equipment Performance
The wheel-type mobile crushing station has a short wheelbase and a small turning radius, allowing it to navigate without damaging the road surfaces. It can travel flexibly on regular highways and within work areas.
The track-type mobile crushing station operates on tracks, enabling it to turn in place. Its standard configuration includes wireless remote control, making it easy to load the crusher onto a trailer and transport it to the operational site.
Product Outcomes
Currently, mobile crushing stations are used for the processing of construction waste. The recycled aggregates produced by mobile stations have good particle shapes, which is beneficial for recycling. The semi-open discharge system is suitable for crushing construction waste containing a small amount of rebar, resulting in fine output with minimal over-crushing and well-shaped particles. This makes it particularly suitable for producing environmentally friendly bricks.
Prix
Generally speaking, the price of track-type mobile crushing stations is slightly higher than that of the same series of wheel-type mobile crushing stations.
