·The crusher feed rate can increase to maintain the same crushing rate Taggart expressed the relationship between crusher capacity and reduction ratio in terms of a reduction ton or tonne Q R defined as Q R = Q T ⋅ R 80 where Q T is the capacity in terms of actual tonnage crushed per hour The quantity of feed actually crushed is
·In a crusher s design attention to the reduction ratio is critical This ratio reflects the degree to which the material is reduced in size from the feed to the product A high reduction ratio indicates a powerful crushing capacity such as reducing 150 centimeter wide iron ore to a 30 centimeter wide material
·Naturally it costs money to build such characteristics into a crusher and for that reason it is hardly to be expected that this improved design will entirely supersede existing standard models of the Blake crusher In very many applications receiving opening rather than optimum capacity is the predominant factor For such applications
Host and manage packages Security Find and fix vulnerabilities
·Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel depending on the character of the material to be crushed and the particular class of service for which the machine is intended Standard crushers in the small and medium sizes are customarily fitted with chilled iron head and concaves for crushing soft and medium
·3 JAW CRUSHER • A Jaw crusher is a machine designed to reduce large rocks into smaller rocks gravel or rock dust It is also called Toggle crusher • It may be used to reduce the size or change the form of waste materials so they can be more easily disposed of or recycled or to reduce the size of a solid mix of raw materials
·From Allis Chalmers Superior Primary and Secondary Crushers ° Actual required depends on stone hardness reduction ratio and so on If a 60 in gyratory crusher is to process material from a quarry where a shovel loads the raw material the shovel would probably have to have a dipper capacity of at least 5 cu yd to be compatible
Table 5 lists the technical specifications of the Blake type jaw crusher used The CCV methodology includes several modifications sample sieve sizes and mass calculations etc of the CI
