1. Jaw crusher The jaw crushers are popular primary crushers for coal. They are often used in mines and quarries where large amounts of coal are mined. The working principle of the jaw crusher is to use compression force to compress coal between a fixed jaw and a movable jaw for coarse crushing.
The design is a single rotor Φ800 × 900 mm, irreversible multirow hinged hammer hammer crusher. It is suitable for crushing limestone, coal and gypsum or other medium hardness ore, crushing the material surface is not more than 8% moisture. This machine is gearing rotor, grate, and a framework of several parts.
for is 120mm, width, W, of each roll is 150mm, and the maximum roll gap, l, is 5mm. Maximum Size of the Particle that can be Fed into the Roll Crusher The maximum size of the particle that can be fed into the roll crusher is determined by the radius of the roll R, roll gap, L and the angle of nip .
LC201 model is recommended for crushing 2in (51mm) and smaller samples. It processes at a maximum rate of about 1,000lb (454kg) of coal material per hour. The final size is approximately 1/16in () and the rotor speed is 3,450rpm. Covered Feed Hopper capacity is ³ (), and the crushing chamber is 7x6in (178x152mm).
Primary Crusher. Primary crushers are heavyduty rugged machines used to crush ROM ore of (−) m size. These largesized ores are reduced at the primary crushing stage for an output product dimension of 1020 cm. The common primary crushers are of jaw and gyratory types.
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

Moreover, crusher manufacturers are making improvements to the equipment that extends the life of the rolls and the average time between maintenance. In the eastern, where a majority of the coal production is washed, primary crushers are usually reducing a 20 to 24inch feed to a more easily conveyed 4 to 6inch top size.
The process remained much the same, but the scale of process equipment was increased substantially. Fig. 2b shows a large gyratory crusher processing run of mine ore to 100150 mm followed by two stages of cone crushing to generate a P80 of 612 mm which could be fed into a large ball mill operating in closed circuit with hydrocyclones.

Jaw crushers we have more installed jaw crushers than anyone in the world. The leading choice due to their high reduction ratio and heavy duty design. Cone crushers capacities available to suit all
The article gives advice on crusher selection and application. Some factors dictating selection include the desired product size, capacity, Hard Grove grindability index, percentage of rock to be freed and hardness of that rock. The hardness of coal probably has greatest impact on product fineness. 2 refs., 1 fig., 1 tab.
Crushing tests were conducted using a pilotscale doubleroll crusher with a diameter of 350 mm, a length of 150 mm, and rolls with reticulated surfaces. The crusher was operated at 20 RPM. The coal samples in four different size classes ( × mm, × mm, × mm and. Shape factor
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 ...
For the 1in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/ = sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least + = sq ft.

As a matter of fact, where the secondary crushers are fitted with straight concaves, or jaw plates, as used to be standard practice, the difference between product curves on screened and unscreened feed was not significant, and no great discrepancy was introduced by considering them under the one heading.
The actual capacity was obtained to be 301 kg/h after the performance evaluation of the machine, and it has a 98 % material recovery rate and % machine efficiency. The machine has a ...
Table Source: Wikipedia (Crushers) Specifications and Features Important specifications and features when selecting industrial crushers include: Feed size, material, and hardness must be considered. Output size ranges. Crushers accept dry or wet input, or both. Crushers are feed in batches or continuously. Some units are mobile.
The article concerned the problem of coal preparation for gasification purposes. The main aim was to design the coal crushing circuit, which would produce the material within the particle size range between and 5 mm. The onestage crushing circuit based on hammer crusher was proposed.
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 m. Product: 300mm (for transport) to 200mm (for SAG mill) Feed Rate:
