The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.
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.

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.
The research of methane adsorption on tectonic coal is an important content to gas disaster prevention and coalbed methane (CBM) exploration in outburst coal seams. Many projects of methane adsorption capacity and behavior of tectonic coal, such as adsorption difference between tectonic coal and its untectonic coal, adsorption evaluation of tectonic coal, factors for adsorption capacity of ...
The capacity of the coal transport truck is 100 t/h; the production capacity of electric shovels 1, 2, and 3 is 2800 t/h; and that of 4, 5, and 6 is 1250 t/h. The crushing production capacity of the three crushing stations is 2000 t/h on No. 1, 2500 t/h on No. 2, and 2500 t/h on No. 3.
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.
HIGHCAPACITY ROLL CRUSHERS The large surface mines in the West scoop up the coal, then crush it and ship it. The crushers range from 2,000 tph to 6,000 tph, breaking 48in. lumps down to 2 x 0in. Mines these days want higher capacity and longer wear life, explained Phil Schaefer, TerraSource Global's regional sales manager for the western ...
How to calculate the Roll Crusher Capacity using a Formula. ... Singleroll coal crushers are driven by the same gearandpinion arrangement used in singleroll stone crushers. Peripheral speeds range from about 400 to 800 ft/min, the doublerolls usually running at higher speeds than the singleroll machine.
Mine haultruck capacity is an important factor at primary crusher installations, because it is costeffective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine's trucks, then operators must slowly meter the ore into the receiving hopper.
Best suited for secondary crushing applications, cone crushers are designed to crush presized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher.
