Feb 26, 2014 PRIMARY CRUSHER SELECTION CRITERIA • Will it produce the desired product size at required capacity • Will it accept the largest feed size expected • What is the capacity to handle peak loads • Will it choke or plug • Is the crusher suited to the type of crushing plant design • Is the crusher suited for underground or in-pit duty ...
A crusher’s wear parts need to last as long as operationally-economically possible. Typical numbers are for liner and mantles to have a useful wear-life of almost 2,000,000 tonne on abrasive taconite and 9,000,000 tonnes on porphyry copper ores. Dependability and long service life are landmarks of good primary crusher design of up to 30 yrs.
CRUSHER SELECTION QUICK GUIDE 1. A typical example of primary crushing is reducing topsize from 900 to 300 mm. 2. A typical example of secondary crushing is reducing topsize from 300 to 100 mm. 3. a typical example of fine crushing is producing concrete aggregates in fractions below 30 mm. 4.
Design Raptor cone crushers have been designed with input from plant operations and maintenance people around the globe. This input has led to many designs and features that reduce maintenance time and increase production. Raptor cone crushers’ critical load bearing components meet specifications that typically exceed what is commonly
This is not intended to be a typical situation, though it does involve common crusher and screen units often used in aggregate plants. Crushing Screening Plant Assessment Example. Quarry rock of 12 in. maximum size is to be handled in a two-stage crusher plant at the rate of 70 tons per hour.
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping ...
Plant Design CHEN 451 Engineering design of new chemical and petrochemical plants and the expansion or revision of existing ones require the use of engineering principles and theories combined with a practical realization of the limits imposed by industrial conditions. A
Figure 6.4 is a typical set-up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a roll crusher. Such circuits are chosen as the feed size to standard roll crushers

Secondary and tertiary crushing, if nece ssary, are the final steps in reducing the material to a desired product size. Historically, cone and roll crushers were the most common choice crushers, but in recent years impact crushers are more widely used. These crushers also are sometimes used as primary crushers for fine-grained gravel deposits.
The crushing force is doubled compared to single toggle crushers and it can crush very hard ores. The jaw crusher is reliable and robust and therefore quite popular in primary crushing plants. The capacity of jaw crushers is limited, so they are typically used for small or
Aug 01, 2014 Above 1000 tph primary gyratory crushers begin to look interesting, and after the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.
Crushing reduces the overall topsize of the ROM coal so that it can be more easily handled and processed within the CPP. Crushing requirements are an important part of CPP design and there are a number of different types. Screening. Screens in screening plant are used to group process particles into ranges by size. Dewatering screens are used to remove surface water from the product.

The disadvantage of this type of crusher, when high capacity is required, is the relatively small discharge width, limiting the capacity as compared with the discharge circuit of a gyratory crusher. Jaw crushers are mainly used in plants producing up to approximately 1600 t/h. Primary crushing with gyratory crushers
