The main reason for this inefficiency is in the random distribution of forces on the particles inside the crusher. With certain simplifications, the theoretical energy efficiency of comminution can be estimated to fall between 5 and 10 % (Legendre & Zevenhoven, 2014) while the measured energy efficiency in actual comminution testing As important equipment in the process of coal preparation, crushers can improve the crushing efficiency of materials as well as product quality [1,2].However, because of high belt speed, high throughput, and invisible iron crushing conditions in industrial production, whereby in a large coal preparation plant with a capacity of 30 Feeding Material Identification for a Crusher Based on Deep

In Bubbling Fluidized Bed Combustors (BFBC) utilizing coal, efficient combustion requires that feed size of coal particles be in the maximum size range of 2 to 6 mm. This requires that the comminution process be effective. In this work, various types of coals have been comminuted in an impact crusher.The size reduction process is Shanghai TY Machinery Co., Ltd. is a high-technology minerals processing company, Professional manufacturer of mini.

The coal agglomerates are relatively low-strength, with considerable cracking of the particles, and so following the HPGR with a ball mill or a roll/race pulverizer is more efficient than using the ball mill or pulverizer alone (Fuerstenau et al., 1995). The HPGR is more suitable for pulverizing coal than for breaking it down to a suitable feedThe plate warping reduces the crusher performance, resulting in low crusher efficiency, high cost of replacing the crushing plates, and higher energy consumption.

For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 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 20.1 + 15.2 = 35.3 sq ft.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.

The coal rock crusher is classified according to the working principle and structure. The crusher machine can realize to deal with the massive and high efficiency of coal. At present, the more widely used is the hammer crusher. The machine can crusher the coal that larger than the size of the discharged material.At the second stage, the studies were carried out for a coal charge consisting of two classes of 3-10 mm and 10-20 mm, the finished class 0-3 mm was removed (conditionally considering the screening efficiency E s = 100 %). The experiments were similar to the first ones. At the third stage, studies were carried out for a coalExperimental Studies of the Process of Crushing Coal
