Fote Heavy Spar Grinding Machine

The uses of heavy spar are in added-value applications which include filler in paint and plastics, sound reduction in engine compartments, coat of automobile finishes for smoothness and corrosion resistance, friction products for automobiles and trucks, radiation-shielding cement, glass ceramics and medical applications. Heavy spar is supplied in a variety of forms and the price depends on the amount of processing; filler applications commanding higher prices following intense physical processing by grinding and micronising, and there are further premiums for whiteness and brightness and color. Todays, with the rapid development of construction industry, the demand for barite has been significantly rising. Global heavy spar industry has witnessed a leap in the price and output. Therefore, plaster producers should seize this valuable chance of development.

As for the processing flowchart of heavy spar, it mainly can be divided into the crushing stage and grinding stage. Large-size heavy spars first enter the jaw crusher to be crushed to smaller size. Then they are lift to the storage room by elevator. Later, vibrating feeder will feed smaller barite stones into the grinding chamber evenly and gradually. After being grinded, the powder will be blowed to cyclone by blower. Then the material will be transferred to storage room through pipes, and then will be discharged as final products. The whole process works in a negative pressure environment. First, through pipes, the air from the blower enters the cyclone collector above the storage room along with powder, and then returns to the blower through return pipe. In the way, air can be recycled. There is a powder locking equipment under the cyclone, which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity. In addition, the residual air and dust under the main unit will be transferred to dust catcher equipment through pipes and be cleaned there....
