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.
This type of crusher is generally used with soft materials like coal, seeds or soft metallic ores. ... Apt dimensioning of the discharge conveyor with regards to crusher's capacity. Selection of proper material and size for the impacting members. Setting of the optimum number of hammers, rotor speed, etc.
By referring to equipment manufacturer's bulletin on crushers, Fig. 1, a crusher producing 80% passing 3/4″ requires a close side setting of approximately 5/8″. Since the selected crusher capacity must be in excess of 143 tons per hour, the next higher figure (159) is chosen. The 159 indicates a 548 crusher size with 1″ eccentric throw.

Roll crushers GR Series .....C are designed for crushing coal. Crushers are characterized by high efficiency, high performance and low operating costs thanks to the selction of rolls: diameters of 800, 1000, 1200 mm. Proper selection of rotational speed of the toothed rolls our crushers the phenomenon of surge crushing coal and pulping the ...
Properties of coal gangue feed, especially its particle size distribution (PSD) and variable hardness, result in considerable impacts on both the efficiencies of the circulating fluidized bed (CFB) boiler and wastage of crushers. These two aspects are addressed in this study. First, the Aspen Plus software was used to optimize the coal gangue crushing system for the CFB boiler; it facilitated ...
proposed a crusher with the help of a pneumatic singleacting cylinder crank mechanism. Hadi et al . [7] developed an automatic crusher using a programmable logic controller with an inductive and capacitive sensor to detect whether the object is metal or nonmetal. Despite the growing interest in crusher design
McLanahan specializes in a variety of crushing solutions to reduce ROM coal to a transportable and marketable top size. McLanahan crushers can take the coal producer through all stages of crushing process, from initial reduction in the primary stage to further reduction and refinement in the secondary and tertiary stages, all while minimizing the generation of dust and fines.
Typical rules for primary crusher selection: Rule 1: Always use a jaw crusher if you can due to lower costs. Rule 2: For low capacity applications, use jaw crusher and hydraulic hammer for oversize. Rule 3: For high capacities, use jaw crusher with big intake openings. Rule 4: For very high capacities, use gyratory crusher.
Commonly, Gyrol crushers are used as secondary crushers due to its high crushing capacity. The machine is easy to operate and has low running costs. These gyrol crushers can be used in different applications such as mining, highways, construction, chemical processing, etc. ... Be it coal, salt, ore, rock, wood chips or anything like clay, the ...
The selection of a crusher for tertiary crushing calls for both practical experience and theoretical knowhow. This is where producers should call in an experienced applications specialist to make sure a system is properly engineered. Types of crushers. Most crushers used for aggregate production fall into one of three main categories/types:
With numerous options available, finding the perfect one can be overwhelming. However, fear not! In this blog section, we will explore various aspects to consider when choosing a coal, it is essential to evaluate your specific needs. Determine the size and type of coal you are working with, as well as your required output capacity.
Screening capacity can be described by the following formula with factors specified below: Qu = A x B x C x D x E x F x G x H x J x K x L x Af, where: Qu = Screening capacity. [t/h] (passing through) A = Nominal capacity [ (m³/h)/m²] (passing through) B = Oversize factor. C = Halfsize factor. D = Deck location factor.
1. Wet Coal Jaw crusher: (1) The jaw crusher is a driven extrusion type, which consists of two jaw plates, a movable jaw and a static jaw, forming a crushing cavity. Simulate the movement of two jaws of an animal to complete the material crushing operation; (2) Specifically, the jaw wet coal crusher is suitable for feeding granularity of 1200mm, with a wedgeshaped adjustment outlet.
There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.
The specifications and manufactured limitations, rather than economy, generally govern the selection of crushers. To find the required areas of screen, the rate of feed of material as well as gradation of the feed must be known. The 1½in. screen under the jaw crusher is the top deck—no deck correction factor will be necessary.
Coal breakers and crushers. There are a number of breaking devices commonly used for reducing the top size of "RunofMine" coal. These vary in their capacity and ability to deal with very hard, soft, or sticky coals, and in some cases they can also reject coarse rock that contaminates the coal. Rotary Conventional ...

Weight: 220, 378 kg. 5EJCA Series Jaw Crusher is designed for primary crushing of mediumhard, brittle and tough materials. Typical sample material includes coal, coke, limestone and so on.
Given the total raw coal capacity of the surveyed plants (158,187 tons per hour), this corresponds to a cleancoal capacity of 790 million tons per year, assuming 24/7 operation. The number of preparation plants increased by 53 since the 2000 survey, and at least 10 new plants were built and 25 were significantly upgraded in the
Nowadays, with a maximum annual capacity of 30 million tons in one large coal preparation plant, the corresponding belt speed can reach 7 m/s and the coal layer thickness will be more than 500 mm. These lead to harmful components, such as iron, gangue, and wood, being mixed into the coal and seriously damaging parts of sizer crushers (sizers ...
