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.
Some researchers have conducted a series of studies on the faults of different crushers. Targeting sensor signals such as the vibrations during the working process of the crusher, Zak et al. [3] used Alphastable distribution for analysis and Jha et al. [4] studied coal ring crushers by measuring the horizontal vibrations of the coal crusher.
The difference between the cumulative percentages at the ″ and ″ points on the curve gives us the amount, of such product to be expected from the output of the primary crusher This is 85 minus 43, or 42% of the primary crusher product. If our problem had covered a crushing condition calling for 80 instead of 85% passing the opening ...

[t/h] (passing through) A = Nominal capacity [ (m³/h)/m²] (passing through) B = Oversize factor. C = Halfsize factor. D = Deck location factor.
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.
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.
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.

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 ...
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 ...
A cone crusher and a vertical shaft impact (VSI) crusher were operated in closed circuit to compare the performance of the two different crushing machines. The crushers were operated in closed ...
The test results in a value for HGI were generally between 30 and 100. A high value indicates that a crusher using this material will have a high output while a low value indicates the crusher will have a reduced capacity using this material. Galena was assumed to have an HGI value of 100 and lower value of HGI means harder material. 4. Results
Jaw Crusher Capacity Estimation. The capacity of jaw crushers is a measure of the mass or volume of crushed material produced in unit time of operation. The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings, 3.
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.
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.
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.
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 ...
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.

The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of Wet, sticky and extremely hard or tough feeds will tend to reduce crusher capacities.
Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.
