In mineral production , the role , the crushing equipment is very significant, and therefore to choose the right , the crushing equipment. Specific selection method below.
Selection , the crushing equipment to determine the factors to be considered in addition to crushing equipment selection , but also consider the maximum size of the crushed product segment and the segment crushing requirements ( or design ) product granularity.
Large and medium-sized pieces of ore concentrator crushing hard and medium can crushed ores , the secondary and tertiary crushing often used cone crusher, cone crusher crushing chamber by the shape and length can be divided into parallel with standard, medium and short head type 3 category. Cushioning and protective devices these three categories of equipment mostly spring , there are hydraulic . Broken equipment often used in standard cone crusher or medium-sized cone crusher, crushing equipment commonly used in the short head type cone crusher . If the two-stage crushing process , and the second choice of medium cone crusher . Cone crusher cone crusher specification to ( fixed cone ) bottom diameter (mm) said its models with "B", "Z" and "D" represent the standard, medium and short head type . Cone crusher feed particle size should be less than 0.85 times the maximum feed opening width. Production capacity cone crusher large crushing ratio, suitable for crushing hard and medium hard ore minerals . The disadvantage is unsuitable for processing ore containing more than clay , Pai mine mouth can not be too small. Hanging plate cone crusher is a new type of ultra- fine crushing equipment. Small concentrator second crushing equipment, generally used crusher , hammer crusher . Most large-scale concentrator crushing operations with full jaw crusher solution.
Equipment installed:
Crusher is suitable for crushing medium can be broken and brittle mineral ores . It has a single rotor and double rotor of two types. Specifications expressed in the rotor diameter and length. Compared with other types of crushers , light equipment weight, small size , large capacity , simple structure, easy maintenance. Low energy consumption per unit of production , consumption ratio jaw crusher save 1 /3. Crushed product size uniform , fine-grained content and help to improve the efficiency of the grinding machine . Selectively crushed ore crushing too little . Crushing ratio, can be a complete request crusher and crushing machines , thus simplifying the process , saving investment. Disadvantages are: strike plate and back plate is easy to wear and require frequent replacement ; big noise, dust and more .
Roll crusher , also known as the roll crusher , roll it flat and Roll categories. Specifications expressed in the diameter and length of the roller . Roll crusher for crushing and requirements with clay and more uniform particle size of a medium can be broken and brittle ore crusher product size may be less than 1 ~ 2mm. It is characterized by simple structure, large crushing ratio , too little crush . Disadvantages are: low production capacity , an area of large , uneven wear of the roll surface . High-pressure roll crusher fine and uniform particle size , can effectively reduce the energy consumption of grinding operations.
