A crusher is a machine that uses mechanical energy to break blocks of stone, concrete, or other building materials into smaller blocks of a specific grain size.

Crushers are classified according to the fineness with which they fragment the starting material. There are primary or secondary crushers (coarse finished products) and tertiary or quaternary crushers (fine particle finished products).

Mobile crushers with the most comprehensive product series-coarse crushing, medium crushing, fine crushing, ultra fine crushing, sand-making and screening.

As crushing and screening equipment, Mobile Crushing Plant can move on the production site automatically.

Mobile crushing and screening plant is researched and designed by our experienced engineers. It is of stable performance and beautiful structure. Our mobile crushers are able to be widely used in phases such as coarse crushing, intermediate crushing, fine crushing, ultra fine crushing. sand-making sand washing, sand shaping and screening in fields of metal mines, building aggregates and solid waste treatment, etc.

Granite is composed of feldspar, quartz, biotite and other ingredients. It has compact structure, high hardness, no debris, high temperature, strong durability, and low water absorption. It is a good natural stone.

The broken granite can be widely used in construction, bridge arches, pavement, foundation stone, chemical industry, metallurgy and other fields. It is an investment project with development prospects.

Applications of granite sand and gravel aggregates in different sizes

80-150 mm (gravel in over-large size)
40-80 mm (gravel in large size)
20-40 mm (gravel in medium size)
5-20 mm (gravel in small size)
Under 5 mm (sand)

If you need to make a lot of sand for your business you are going to want to invest in a quality sand making plant. This plant allows you to take rocks and dirt and turn it into sand. You can produce all of the sand you need.

The machine can make other things as well like gravel. The machine is easy to use and it is crucial to have this machine if you need to produce these materials for your construction business.

The machine crushes grit and turns it into sand and plaster. Whether you are using it with rocks or stones, you can rely on the sand maker plant to crush the large materials and process them into grit and stand.

The machine consists of a vibrating feeder that moves the materials into the jaw crusher. Once the rocks have passed through the jaw crusher they go into the impact crusher where the materials are broken down into fine pieces. The vibrating screen screens out the larger pieces so you are left with the grit and sand.

1. What is  Neodymium Iron Boron Magnetic Powder (NdFeB) ?
NdFeB is also called magnet. This mineral is a tetragonal crystal composed of neodymium, iron and boron. Has a strong magnetic attraction.

2. The application of Neodymium Iron Boron Magnetic Powder
The strong magnetism of NdFeB makes it called a permanent magnet, and it is also one of the most commonly used rare earth magnets. This kind of magnet is widely used in electronic products such as hard disks, mobile phones, earphones, and batteries.

In the entire production process of neodymium iron boron, it is necessary to make powder and then complete a series of later processing processes.

1. Specific powder making process is: The raw material is fed through a bucket elevator into a European mill or a trapezium mill or a vertical mill for grinding, where it is ground to the required particle size and then passed through an analyser for powder selection and then into a powder collector for bagging.
