Gyratory crushers are the part of primary crushing for heav y duty operation that reduces large rock pieces r esulted durin g mine blasting into the gravel size rock mixture. Design of this crusher is
In any operation that incorporates size reduction, selecting the primary crusher is vital to the overall success. The main parameters to first decide on a general type of crusher are the impact strength, product size and material hardness. The final design for a crusher will be selected primarily based on required capacity, feed and product size.
Design criteria can be calculated from a simple spreadsheet as shown in Table 2. Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable
Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
With the development of a completely new type of crusher, the so-called eccentric roll crusher type ERC25-25, thyssenkrupp says it has achieved a quantum leap in primary crushing. The new crusher features a particularly flat and robust design and high throughputs of up to 3,000 t/h, enabling it to process hard rock and ores efficiently and.
The number of crushing stages necessary to reduce ore to the proper size varies with the type of ore. Hard ores like gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: crusher selection, crusher layout and process design. 2.4 Crushers
Dependability and long service life are landmarks of good primary crusher design of up to 30 yrs. The selection of the primary crusher must consider best-in-breed maintenance services as the whole mine’s production goes through 1 or 2 of these machines and make the in-pit crusher a vital piece of equipment .

A Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws. Primary jaw crushers are typical of the square opening design, and secondary jaw crushers are of the rectangular opening design.

The term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant. The factors influencing the selection of a crusher for this service
Crushing Plant Flowsheet & Design-Layout. In the crushing section, the ore as it comes from the mine is broken down dry to a size suitable for the wet grinding machines ; these can, if necessary, be made to take lumps of 2-in. size, but they work much more efficiently if their feed is ½ in. or less. Before the advent of the Symons cone 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.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
The ore is a little harder and the sizing more critical however, this means the positioning of the equipment has to change a little. The ore is still discharged from the primary crusher to the scalping equipment. For this type of application this is usually a screen. Again the fine material is removed from the circuit while the course gets crushed.
