· P&Q University Lesson 7: Crushing & Secondary Breaking. In the quarry, crushing is handled in four potential stages: primary, secondary, tertiary and quaternary. The reduction of aggregate is spread over these stages to better control the product size and quality, while minimizing waste. The primary stage was once viewed merely as a means to ...
Impact Crushers - Primary. McLanahan offers a wide selection of Impact Crushers for quarried limestone and semi-abrasive minerals. McLanahan draws from the 75 years of field experience with the Universal line of Impactors, which includes impact breakers and Andreas-style impactors. At present, we offer the New Holland-style primary impact ...
· Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher. The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in size.
Primary breakers that treat ROM coal are usually rotary breakers, jaw crushers, or roll crushers; some of these are listed below. Rotary Breakers ( Fig. 1 ). The rotary breaker serves two functions—namely, reduction in top size of ROM and rejection of oversize rock.
· Crushers and lump breakers are used to reduce lumps in chemicals, pharmaceuticals, foods, agricultural feeds, pet food, aggregates, and other materials, to a consistent size. The offerings range from slow-speed machines for coarse or hard materials, to higher-speed machines that produce finer discharge sizes.
· Hydraulic breakers are often used as standard in the secondary reduction of oversize boulders in the rock pile where mounting a breaker on a mobile carrier is said to provide a unit that can be used at several points in the quarry. Terminator, an impact breaking tool, is used as the primary means of winning rock.
The rock breaker boom system is used to break up oversized pieces in the crusher or to free up the transport routes to the crusher. Uses for primary gyratory crushers Large and powerful rock breaker boom systems with large hammers constructed for continuous and heavy operation are intended for primary gyratory crushers.
The breaker booms and hammers are engineered to meet the requirements set by rough primary crushing applications. These packages are optimized to work together and support primary crushers, ensuring the best productivity of the whole primary crushing station.
Secondary Impact Crushers. The Stedman Grand-Slam secondary impact crushers are built to handle thousands of materials, ores, and chemicals in wet and dry applications.

Available in three sizes, the well proven original Parker ''Kubitizer'' Impact breaker produces material with outputs ranging from 40-200 tonnes per hour and is ideal for working in a composite crushing arrangement with Parker primary crushing plants, screens and conveyors. Feed material is broken along natural lines of weakness (the grain ...
Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
· Rock breakers are commonly used in primary crushing stations to break oversized boulders that are fed into the crusher and to clear clogging in the cavity. Today, most of the primary stations use ...
Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.

· Fairmount type crusher During the same years wherein the industry was concerned with development of larger and still larger primary crushers,another member of the family was born: the single, sledging- roll crusher. The Allis-Chalmers Co. entered this field in 1911 ...
small range booms are light-weight, multi-purpose breaker units typically used in quarries, next to primary crushers, to clear any blockages and bridging in stationary crushing plants as well as mobile crushers. Light-weight booms also offer an effective solution for demanding specialized applications such as the breaking of refractory linings in metallurgical …
crusher. Primary Crusher — The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary or tertiary crushers. Product — Output from the crusher. Reduction Ratio — The ratio of the top size of

Primary Impact Crushers are preferred for their high capacity and reduction ratios in crushing soft and medium hard rocks like limestone, gypsum. Due to their operating principle, reduction ratio is higher than in jaw crushers.
· Crushers and lump breakers are used to reduce lumps in chemicals, pharmaceuticals, foods, agricultural feeds, pet food, aggregates, and other materials, to a consistent size. The offerings range from slow-speed machines for coarse or hard materials, to higher-speed machines that produce finer discharge sizes.

The jaw crusher is also called the jaw breaker. It has been widely used in many fields, such as mining, metallurgy, building materials, highway, railway, water conservancy, chemistry and so on. It is able to crush all kinds of materials whose compressive strength is
In compression crushing, jaw crushers tend to be more of a blunt instrument compared to cone crushers, which is why they''re often used in the primary rock crushing circuit stage. Jaw crushers are also known as "rock breakers" and are used to break up larger, harder materials into more manageable pieces.
