·Introduction A stone crusher plant is a machine designed to reduce the size of large rocks eliminate gravel or rock dust to smaller sizes for various applications These plants find application in quarrying mining construction and recycling operations Stone crusher plants consist of several components including a primary crusher secondary crusher and vibrating
Nordberg® GP300S secondary cone crusher has lower installation height that reduces installation costs since smaller support structures and shorter conveyors are needed The IC50C crusher automation enables adjusting Nordberg® GP300S secondary cone crusher from a distance which reduces risks and improves the safety of the plant personnel

The Jaw crusher is used as Primary and Secondary crushers for crushing all kinds of minerals and rocks with compressive strength less than 320 mpa There are two types of Jaw crusher Compare this product Remove from comparison tool See the other products Henan Hongxing Mining Machinery CO LTD
The feeder s main function is to regulate and maintain a steady supply of material for the crushing process ensuring that the crusher operates effectively and continuously A crushing plant has different sections primary secondary tertiary where different crushing and transport cycles are done in order to obtain different stone sizes
·There are five crushers consisting of primary crusher secondary crusher tertiary crusher and two crawler crushers at this crushing facility The ore coming from the quarry is passed from the grid with a clearance of 150 mm and the material above a grain size of 150 mm are conveyed to jaw crusher with a capacity of 400 tonne/h
·Secondary Crusher As the name suggests secondary crushers follow the primary crushers and are used to further reduce the size of the material They are designed to handle medium sized materials and produce a finer output compared to primary crushers Tertiary Crusher Tertiary crushers are employed when further reduction in size is required
2 ·It is common to use multiple crusher types within a project and set them up as stations in a circuit format to perform the necessary material reduction work In many cases primary secondary and tertiary and quaternary stations are installed to reduce the rock to the desired size shape and consistency
Secondary coal crusher Used when the coal coming from the supplier is large enough to be handled by a single crusher The primary crusher converts the feed size to one that is acceptable to the secondary crusher Read more View chapter Explore book Read full chapter
·This mechanism ensures a more uniform and concentrated force distribution across the material resulting in efficient crushing The double toggle crusher is known for its ability to process hard and abrasive materials with a higher reduction ratio making it ideal for both primary and secondary crushing applications
·An impact crusher uses mass and velocity to break down feed material First the feed material is reduced as it enters the crusher and makes contact with the rotating blow bars or hammers in the rotor Secondary breakage then occurs as the material is accelerated into the stationary aprons or breaker plates
Impact Crushers Secondary The NGS Impact Crusher is extremely versatile The most common application involves taking primary run limestone from either a Jaw Crusher or impact breaker and reducing it into a construction grade aggregate However with the optional third curtain assembly it is possible to increase the amount of chip stone for
·The need for the secondary crusher is dictated by the size of the product required The product size from a primary crusher is limited by the possible reduction ratio which normally is around 10 1 The feed size to a primary crusher from the mines could be 1 m; thus the maximum product size possible is 10 15 cm which is normally too
·Secondary Crusher These crushers break down materials into smaller sizes and often have a reduction ratio less than 3 1 in crushing A secondary impactor hammermill and cone crusher are popular secondary crushers Still note that you may use a jaw crusher as a secondary crusher in some cases
The secondary crusher housing is a rugged fabricated steel plate construction with external bracing for increased strength For quick and easy inspection of the internal wear parts the housing is fitted with large doors which are secured / opened by a special dove tail locking mechanism The housing system is stress relieved to increase its

·The type of secondary crusher will vary according to the characteristics of the ore Usually a cone type crusher is recommended for this secondary crushing although in many cases a jaw crusher can be used as the secondary crusher setting up the jaws closer than in the primary crushing operation The interchangeability of parts is important if
·Figure 1 Double roll crusher geometry Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4] [5] For rolls that have equal radii and length tangents drawn at the point of contact of the particle
·The most common HPGR based circuit involves feeding primary crusher product to a secondary crushing circuit with of cone crushers in closed circuit with screens followed by tertiary crushing with HPGRs also operating in closed circuit with screens The product of these two stages of crushing and screening then passes to secondary milling
Hammer crushers are used either as a one step primary crusher or as a secondary crusher for products from a primary crusher They are widely used for crushing of hard metal scrap for different hard metal recycling processes Pivoted hammers are pendulous mounted on the horizontal axes symmetrically located along the perimeter of a rotor and

·Where the material is not reduced sufficiently in the primary crusher it is then crushed by a secondary crusher to achieve the correct size of the material Wear on parts of the crushers affect the performance and volume of material being crushed the parts subject to high impact and abrasive wear include the hammers rotors teeth and mantles
·Standard Secondary Cone Crusher Refer to Fig 1 The Standard Cone crusher is normally applied as a secondary crusher in a multi stage crushing circuit The small diameter feed distributor and the wide throat opening at the top of the liners enable the Standard Cone crusher to accommodate the larger feed produced by the Primary crusher
