a) Maximum Feed Opening — 625MM (25 In.) b) Recommended Product Range — 100MM to 19MM (4 In. to ¾ In.) Short Head (Tertiary) Cone Crusher (Refer to Fig. 2): The Short Head Cone crusher is normally applied as a third stage crusher in plants designed for three or four stages of crushers.
For example, for a largescale quarry or coal mine, choosing a crusher with a larger production capacity is usually necessary to meet production needs. At the same time, it is required for a smallscale construction site to choose a suitable small crusher. The crusher model selection also needs to consider the crushed materials.
As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the twostage pulverizing sec tion.
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 ...
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.

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.
Coal is one of the essential resources in an industry that requires energy. One of the industries that use coal as a source of energy is a steam power plant. In an industry that uses large numbers of coal with a certain size, it requires a coal crusher to change the shape of the coal into the desired shape. A coal crusher is a machine
Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
Criteria for selection of crusher The following are the criteria used in the selection of the right type of a crusher for crushing a material. Production requirement It includes output size and shape, and the required capacity.
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. These can include the owner's engineering staff ...

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.
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 ...
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
Mining of raw materials is a process that consists of several stages. In openpit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive strength, moisture content, capacity of crusher, abrasiveness ...
The width of the crusher must also be considered when taking into account the feed size. Selecting a crusher that is too narrow compared to the size of the incoming feed can result in the bridging of the feed material across the crusher opening. When this occurs, once again, throughput capacity is diminished and plugging of the chutes can occur.
It is stated as a percentage of the new feed to the crusher. The equation for circulating load percentage is: R = 100/E/r1 where R = circulating load, % E = screen efficiency, % r = % oversize in crusher product. To help understand this determination and the equation use, take the example of 200 tph original or new material to the crusher.
Crushers are widely used as a primary stage to produce the particulate product finer than about 50100 mm in size. They are classified as jaw, gyratory and cone crushers based on compression, cutter mill based on shear and hammer crusher based on impact.
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 crushing rolls can be rotated either inward or outward at slow speed and high torque, which minimizes slippage and fines generation. Slowspeed Sizers are selected for the specific material and lump size to be crushed. Tooth profile selection allows the material to be grabbed and pulled into the crushing zone for maximum efficiency.
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.
In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm. Therefore, in highthroughput and complex environments, the problem exists that harmful feeding materials such as iron and gangue are not easily detected, and thus fault diagnosis in the crushers lags behind.
To choose the type of crusher, consider the following factors: Material characteristics: The type of material being crushed, such as limestone, concrete, or granite, will impact the selection of a ...
