The mined ore raw material is coarsely crushed and then passed through a feeder into a jaw crusher for initial breaking and screening.
Materials first enter jaw crusher to be crushed to smaller size.Then they are lift to storage room by elevator.Vibrating feeder will feed materials into 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.The clean air will be discharged so that environment will be protected.The clean air will be discharged so that environment will be protected.Sbm coarse powder grinder can produce right size powder for industry.
Today, the jaw crusher is operated with jaws of a two-piece design, that is a new material solution for iron crusher applications.Another significant achievement has been made with the cone crushers, used at the iron ore fine-crushing stage.
Cone crusher is mainly used for medium-fine crushing, such as iron ore, non-ferrous metal ore, granite, limestone, quartzite, sandstone, river pebble, etc.For hard stones such as cobblestone, granite, coal gangue, if adopt the crushing process of jaw crusher + sand maker, it may cause serious wear of the sand maker.In order to relieve the pressure of the sand making machine, a cone crusher is added in the middle.From the process point of view, adding equipment is equivalent to increasing investment costs, but for long-term investment in quarry mining work, reducing the wear on fine sand making equipment, increasing the service life, creating more profits.Single-cylinder hydraulic cone crusher combines mechanical, hydraulic, electrical, automation, intelligent control and other technologies into one.It has the advantages of high crushing efficiency, convenient maintenance and adjustment, and excellent particle shape of the crushed product, widely used in metal, non-metallic ore, cement, sand and stone, metallurgy and other industries.
Our cone crusher includes symons cone crusher, hydraulic cone crusher, sprind cone crusher.Spring cone crushers are widely used in industries like metallurgy, construction, road building, chemistry etc, to crush many kinds of mid-hard or hard rocks and ores such as iron ore, limestone, granite, basalt, quartz etc.The standard ones are used for intermediate crushing; the medium ones are used for fine crushing; and the short head ones are used for super thin crushing.Compared with jaw crusher, spring cone crusher is of stable structure, high efficiency, easy adjustment, and economical using etc.The spring safety system of crusher acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the cone crusher.The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separated to make sure reliable performance.This type of crushing chamber depends upon the size of feeding and fineness of the crushed product.The standard type (pyb) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.
