The primary crusher is the first stage in the crushing process. It is typically a large machine that takes in the raw material from the mining site and reduces it in size to a more manageable form.Manufacturers tend to use rules of thumb to de-rate crusher capacities for the treatment of highly competent ores that display high Bond crushing work indices (CWi). One such rule is the following: de-rate = (16/CWi)^0.5. However, care is required when using this rule as CWi test methods vary and simplistic approaches do not address all of theRock Crushing Rule of Thumb 911 Metallurgist

Selecting the right type of crushing equipment Quarry

A pit-portable primary crusher can be an economically sound solution in cases where the producer is crushing at the quarry face. In modern plants, it is cost-effective to use a mobile primary crusher, so it can follow the movement of the face where raw material is extracted. The most common use of track-mounted primary crushers is inThis type of crusher consists of a long, conical, hard steel crushing element suspended from the top. It rotates and sweeps out in a conical path within the round, hard, fixed crushing chamberSources of failure on primary crushers in the mines (Cone

Types of Crushers: What You Need to Know Machinery

There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers. Crushing is an versatile process and the kind of crusher you need depends on the 'stage' of crushing. The three main stages of crushing are primary, secondary, and tertiary all of which have their own unique benefits.Secondary crushing is the second stage of material processing after the first crushing. After that, the product to be crushed will pass through a second crusher or a cone crusher, which is effective in crushing such materials. There are also third and fourth crushing stages to obtain smaller sizes of material.What is Primary, Secondary and Tertiary Crushing?

The primary operating costs of a crusher are parts and labour for maintenance, which can vary approximately twice as much as the power for the motor. Gyratory crushers generally cost less than $1500 per hour to run, while Jaw crushers cost less than $200, including electricity (Infomine, 2008).The crusher can produce different crush curves and final grain sizes for the same base material by adjusting the rotor speed in a range of approximately 30 to 40m/s and by adjusting the crusher gap of -100 to +150mm at the lower apron and 0 to 300mm at the upper apron.Evaluating effective mobile crushing systems Quarry
