Raymond Mill Vs Ball Mill

Semi-portable crusher (also for semi-mobile crusher) consists of two main parts: moving parts and working parts.The moving part includes chassis, legs and oil tank, and the working part is fixed on the former part and contains a fixed crusher and power units such as electronic control system.Only with the help of a tractor can a semi-portable crusher move flexibly.

Shale king single roll crushers produce primary and secondary sized products and are designed specifically to process rock.They are ideal for oil shale and materials of similar hardness.

The feeding chute and the counterattack plate of the impact crusher can be equipped with heating device to prevent the material from binding, so the material with large water content can be crushed and the blocking is not easy to occur.

After years of research in production and offering types of mineral crusher machinery, this company has had noticeable activities not only in providing regular machinery but also in building special crusher machinery for various minerals of regional features.

4.Commit to an oil analysis program.Today, oil analysis has taken its place as an indispensable and valuable element of crusher predictive maintenance.There is only one thing that will wear out the inside of a rock crusher, and that is dirty lube oil. clean lube oil is the most important factor affecting the service life of the internal crusher components.

Generally speaking, the major differences between impact crushers, both vertical shaft (vsi) and horizontal shaft (hsi), and cone crushers is the type of crushing force.Impact crushers crush by material impacting another object.Cone crushers use compression crushing where the material is crushed by being squeezed or compressed between two crushing surfaces.Selection of the type of crusher and the crushing process for any application depends on material hardness, and density of the material, feed size, desired product size, and capacity needs; as well as initial costs for each crusher and the cost to maintain each style of crusher.Basic construction and working principle:horizontal shaft impactors consist of a hopper, two or three aprons, a rotor, and blow bars or hammers.Essentially, large products are fed into the hopper where they come into contact with hammers or blow bars to a spinning rotor which crushes the material into smaller pieces.As the larger material gets impacted by the hammers, it comes into contact with each apron rebounding it back to the rotating hammers for another round of impacting until it is discharged out of the hsi.Vertical shaft impactors consist of a feed hopper, a feed tube, a rotor, and either stationary anvils or rock shelves.Essentially, feed material drops through the feed tube into the rotor, which, through centrifugal force, throws the material against stationary anvils made up of composite metal alloys or rocks (through the installation of a rock shelf).When the rock impacts on the anvils or rock shelves, it shatters along natural stress lines, creating a uniform, cubical product.Cone crushers consist of a bowl liner, a mantle, both main shaft and frame, compression, and an eccentric inner and outer bearing.Essentially, material is reduced in size by squeezing the material until it breaks.Specifically, the material is compressed between a moving piece of steel, the mantle, and a stationary piece of steel, the bowl liner.The final products size is determined by the closed-side gap setting between the two crushing members at the bottom.As the cone eccentrically rotates, the material is crushed and works its way down through the crushing chamber, until it discharges at the bottom of the machine.Material composition for the crushing process:in order to understand cone and impact crushing processes, one must know the material that will be crushed, which will determine the optimal crusher for your business needs.When considering the material to be crushed, you must look at abrasiveness, hardness, density, amount of fines, and the finished particle shape you desire.Impact crushers are used to crush softer, less dense and abrasive material such as limestone.Because of its consistent striking process, an impact crusher produces uniform cubical finished products, which are desirable for hot asphalt producers.Depending on the application, impact crushers can have higher wear costs, higher maintenance, and produce more fines.Impact crushers may be used as a primary, secondary, or tertiary crusher depending on the producers final-product-size needs.These crushers are available in stationary, track and mobile designs.Another industry usage is slag, specifically blast furnace slag, which is less abrasive than steel furnace slag and can be broken down if processed through an impact crusher.Cone crushers are primarily used to crush harder, more abrasive and dense material, such as granite, which is used in construction, chemical, metallurgical and silicate industries.Cone crushers can be used in the primary, secondary, and tertiary position.These crushers are available in stationary, track and mobile designs.Cone crushers are also used in the steel furnace slag industry, which is a much more abrasive slag than blast furnace.Overall costs:impact crushers, initially, are less expensive than cone crushers.Although cone crushers are more expensive up front, they will require far less maintenance than impact crushers.The majority of maintenance costs on an impact crusher comes from wear on the blow bars and aprons which if used to crush highly abrasive material, may surpass the initial cost of the cone crusher.As stated earlier, producers must understand their industry needs and the materials they will mine in order to choose the optimal crusher.View telsmith cone crushersview telsmith impact crushers.
