Primary crushers including compression jaw cone impact and gyratory crushers are essential in the first stage of the crushing process reducing large rocks to smaller manageable pieces for secondary crushers; Highly adaptable and can be employed in a variety of industries such as mining construction and recycling;
Primary crushers are machines designed to break down large materials into smaller pieces They are typically the first stage of the crushing process and are capable of handling relatively large sample sizes These crushers are used in various industries to reduce the size of different types of materials such as rocks minerals and ores
OM Siderurgica primary and secondary crushers stand out for a strength and reliability construction obtained thanks to the over dimensioning of fixed and mobile parts the rational design of the parts and the use of special high quality anti wear alloys Thanks to this design OM Siderurgica guarantees to the final customer the desidered output
Primary crushing brings run of mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below Dry crushing includes work on ore as mined which may be somewhat moist when delivered It is succeeded by comminution in water arbitrarily called grinding
Selecting the right primary crusher is foundational to success at a crushing site The primary crusher is the engine that drives the rest of the plant; it s the workhorse that takes blast feed sizes and reduces them to sizes that are manageable for other site components the belts the screens and eventually any secondary crushers on the road to a finished product
Jaw crushers are mainly used in primary crushing stages and are rarely used for secondary crushing As a compression crusher this type of machine generally produces the coarsest material because it breaks the rock along its natural lines of weakness Jaw crushers are an excellent primary stage solution to prepare rock for subsequent processing
Jaw crushers cone crushers gyratory crushers and roll crushers all operate on the compression principle Impact crushers utilize the impact principle while hammermill crushers follow the principle of attrition Compression crushers Jaw crushers Jaw crushers are often used as primary crushers and are perhaps the most popular crusher worldwide
The open air primary crushing station can be divided into fixed primary crushing station semimobile primary crushing station and mobile primary crushing station 1 Fixed primary crushing stations are always located outside the boundary of open pit stope or intermediate platform and some are also located in the concentrator which have the
PE crushers often chosen for primary crushing jobs are built strong enough to take in big chunks of materials and break them down efficiently With PE crushers you can expect a high volume of reduction PEX crushers however shine when it comes to grinding down the already crushed material even more in secondary or tertiary crushing giving
Blake type crushers come in various sizes and are commonly used for primary and secondary crushing roles How Jaw Crushers Are Sized Jaw crushers are sized based upon the dimensions of the top feed inlet gape or the dimensions of the jaws For example a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw
2 Typically the minimum setting on most primary crushers will be about 4 to 6 inches as noted above Compression style jaw cone impact crushers and gyratory crushers are most often appropriate as primary crushing equipment types though there can be overlap between primary and secondary crushers as far as suitable types 2 Secondary Crushing
While primary crushers process material from a much larger scale secondary crushers process material refined to a particular size and shape The key differences between the two types of crushers are the specific function of each and the size of the output they produce When choosing between primary and secondary crushers several factors must
Primary vs Secondary Crushing Jaw crushers are primarily utilized for initial material reduction crushing tasks while cone crushers are used in secondary crushing refining materials that have already undergone primary crushing stages Processing Capacity A key differentiator is the processing capacity Jaw crushers designed for robust
