Coal mill for boiler plant

The coal flow into the boiler is an important factor for a coal fired power plant. But in fact, it is not easy to measure the coal flow from the coal mill to the furnace. The coal flow out of the coal mill is often estimated based on the incoming coal flow.

According to the market research, vertical coal mill is used most widely. There are also other grinding mils like traditional Raymond mill, roller mill, trapezium mill, etc. can also meet different requirements for grinding coal into different sizes and types. Customers can choose an appropriate coal mill according to their specific needs and the output.

Coal powder can improve coal burning efficiency, increase power output and reduce harmful gas emission, etc. As a result, coal mill or coal pulverizer and coal powder processing technologies are increasingly important in electric power plants, steel plants, cement plants and any other industry using injection type coal furnaces.

Artificial Sand Production Line

Large stone is transported to jaw crusher via vibrating feeder for primary crushing. Then crushed material is transported to sand making machine. Then the stones are screened out into several different types with a vibrating screen. Stone with satisfied size is transported to sand washing machine, then it will be final product, while overlarge stone is returned back to sand making machine for recrushing.

The raw material is transferred to jaw crusher for primary crushing by vibrating feeder, then the crushed materials are transferred to sand-making machine through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen. The materials with suitable size will be transferred to sand washing machine, after being washed, then clean final products will be discharged. The others with unsuitable size will be screened from vibrating screen, then will be transferred to the sand-making machine, this forms a closed circuit manifold cycles.

Iron ore beneficiation process plant

Magnetic separation of magnetite iron ores is one of the fastest-growing segments of the minerals beneficiation industry. The tonnage of taconite ores processed annually by magnetic separation zcill, in n few years, reaches 100 million.

Magnetic separation occupies an attractive position in the field of magnetite ore beneficiation. It is a simple effective method, used for some 150 years and steadily growing more important. This type of beneficiation originated in 1792, when William Fullarton was issued a British patent covering the separation of iron ore by magnetic attraction.

The crushed iron ore passes to low intensity magnetic separator, and materials of high magnetic pass to cleaner flotation and thickener flotation. The pure product of flotation cleaner is iron ore concentrate, while the iron materials with low Fe content are moved back to rough flotation for further separation. The product after thickener flotation is grinded by ball mill into fine particles and moved to dehydration tank and then successively to high intensity magnetic separator and disc magnetic separator for further separation. Low content iron ore is moved back to thickener and very content iron ore is discharged as tailings.
