Sep 02, 2019 Today, primary crushing is viewed as more important within the balance of production and proper sizing needs. The size and type of the primary crusher should be coordinated with the type of stone, drilling and blasting patterns, and the size of the loading machine. Most operations will use a gyratory, jaw or impact crusher for primary crushing.

Jun 05, 2021 Primary crushers. The primary crushers directly receive material from ROM (run of mine) after blasting and produces first reduction in size. Secondary crushers. Output of the primary crusher is then fed to a secondary crusher, which in further reduces the size of material. Tertiary crushers. Similarly, output of secondary crusher is fed to ...
In Mineral Processing Design and Operations (Second Edition), 2016. 6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size.
These crushers are designed as two Double Roll Crushers, with both the primary and secondary stage achieving a 4:1 reduction ratio. The intermeshing tooth design in the McLanahan crusher means that no timing gears are required.
gyratories expected soon, as well as secondary and tertiary machines of up to 3,000 mm (120 in). • Rising energy costs are causing owners to increase the integration of mine and mill design, so that they can identify ways of reducing overall electrical power consumption. • Electronic control of crusher discharge opening and feed rate.

Secondary apron is equipped with
Secondary concrete crushers usually have some type of pulverizing jaws and are used on jobs where primary demolition is accomplished by hammers, crushers, blasting, ball and crane, or sawing. In this instance, the primary demolition work creates large quantities of concrete rubble which the secondary crusher further reduces, separating concrete.
A cone (or “conical”) crusher breaks down material with the use of an eccentric rotating head and a bowl. It is often used as a secondary or tertiary crusher. It is best for crushing material 200 mm and less. Advantages of a cone crusher include high productivity and low operating costs.

ratory crusher, and short-shaft gearless gyratory crusher. The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine, and its product normally requires additional crushing before produc- ing the final ...
A crusher can be classified depending on the size reduction factor as follows . a. Primary crusher The raw material from mines is processed first in primary crushers. The input of these crushers is relatively wider and the output products are coarser in size. b. Secondary crusher: The crushed rocks from primary crusher are sent to these

Jul 24, 2015 Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher. The fines will be taken out of the circuit. Once the secondary has finished with the ore it will be reclassified by a second set of screens with the oversize going to the tertiary crusher.
In Mineral Processing Design and Operations (Second Edition), 2016. Abstract. Detail descriptions of designs are given of large gyratory crushers that are used as primary crushers to reduce the size of large run-of-mine ore pieces to acceptable sizes. Descriptions of secondary and tertiary cone crushers that usually follow gyratory crushers are also given in detail.
Impact crusher – Impact crushers are typically used for hard and moderately abrasive stone. The primary impact crusher, also known as a primary breaker, has a reduction ratio of 20:1. Impact crushers are higher maintenance than a jaw, although are still considered low maintenance with regard to their tonnage rate and overall productivity.
