Portable Mineral Grinding Plant,Niger- DRG Crusher

A crusher is a heavy-duty machine used to reduce large-sized rocks, stones, ores, and similar hard materials into smaller pieces. Crushers are fundamental equipment in crushing and screening operations and allow materials of various granulations to be obtained using different types of crushers (jaw, cone, impact, vertical shaft, etc.).

What is the function of a crusher?
Crushers are used in many industries to reduce raw materials to processable sizes. Their main functions are:

• Breaking stones and ores into smaller pieces

• Producing aggregate (crushed stone) for the construction sector

• Preparing raw materials for concrete and asphalt plants

• Reducing ore size before mineral beneficiation processes

• Making concrete and construction waste reusable in recycling plants

How does a crusher work?

• Material is directed into the crusher via a feeder hopper

• Inside the crusher, the material is broken by compression, impact, or shear force

• Crushed material is sent to a screening system and separated by size

• Properly sized products are transported via conveyor belts to stockpiles or other processes

Where are crushers used?

• Stone quarries and aggregate production

• Mining (metallic and non-metallic ores)

• Concrete and asphalt production plants

• Major construction projects such as roads, bridges, dams, ports

• Construction waste recycling facilities

What is a Mobile Crusher?
A mobile crusher is a portable crushing and screening plant mounted on a tracked or wheeled chassis, integrating crusher, screen, and conveyor systems. These systems can be easily moved from site to site and quickly commissioned on location.

What does a mobile crusher do?

• Performs crushing operations directly at the site

• Processes material in place, reducing transportation needs

• Saves time with shorter setup times

• Provides practical solutions for temporary or project-based worksites

How does a mobile crusher work?

• Material is loaded into the feed hopper with an excavator or loader

• It is then crushed by the crushing unit (jaw, impact, or cone crushers)

• The screening unit separates material into desired sizes

• Sized material is conveyed to the stockpile via belts

• All processes are integrated within the mobile system

Where are mobile crushers used?

• Temporary quarries

• Infrastructure projects (roads, bridges, dams)

• Mining sites

• Construction waste recycling projects

• Mountainous or hard-to-access areas as a mobile solution

What is a Stationary Crusher?
A stationary crusher is an industrial crushing and screening plant permanently installed in one location and capable of handling high-tonnage operations. These facilities are built on large areas and designed for continuous, long-term production. Each component is fixed to concrete foundations.

What does a stationary crusher do?

• Performs high-volume rock and ore crushing

• Produces continuous material supply for large-scale projects

• Provides high capacity and operational efficiency

• Supports the heavy demand of industrial, mining, and construction sectors

How does a stationary crusher work?

• Material is unloaded from trucks into a hopper or feeder

• It is then crushed using jaw, cone, or impact crushers

• The screening system separates material by size

• Conveyors transport material to stockpile areas

• All systems are fixed and typically powered by grid electricity

Where are stationary crushers used?

• Large-scale stone quarries

• Metallic ore processing plants

• Concrete and asphalt aggregate production

• Major infrastructure projects such as dams, airports, highways

• Industrial raw material processing facilities

Differences Between Mobile and Stationary Crushers

What is a Mineral Grinding Plant?
A mineral grinding plant is an industrial facility that reduces the physical size of ore to micron levels for enrichment or direct use as raw material in various industries. These plants are a critical stage in the mineral processing chain.

What does a mineral grinding plant do?

• Reduces ore to fine particles

• Prepares material for metal beneficiation (flotation, magnetic separation)

• Produces raw materials for ceramics, paint, glass, and cement industries

• Facilitates the recovery of valuable minerals

• Improves product quality through micron-level grinding

How does a mineral grinding plant work?

• Ore is pre-crushed and fed into the grinding system

• Grinding is carried out using ball mills, rod mills, or SAG mills

• Material is ground by rotation and friction down to micron size

• Ground material is classified using cyclones or spiral classifiers

• Final product is either concentrated or sent directly for industrial use

Where are mineral grinding plants used?

• Metallic mineral processing (gold, silver, copper, zinc, iron, etc.)

• Processing of industrial minerals (calcite, dolomite, feldspar, barite, etc.)

• Cement and clinker production

• Ceramics, glass, and paint industries

• Chemical and metallurgical sectors

• Waste and ash recycling facilities
