Among these steps, screening is an essential process for coal separation [[5], [6], [7]]. Studies show that screening can increase economic benefits and reduce the slime water load of a coal preparation plant. Consequently, it is considered a conducive environmental protection process [[8], [9], [10]].

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

ABSTRACT Screening is used extensively for the size classification of coals. During the screening process, the impact of oversized material often causes damage to the screen surface, which then affects the reliability of the vibrating screen. In this study, an orthogonal experiment was designed, and the influence of vibration parameters on impact force was determined using range and variance ...

Coal is the main energy resource in China and provided 62% of the total energy consumption in 2016 [1]. Coal preparation is the prerequisite for clean coal utilization as well as the most costeffective method for clean coal technology. Screening is an indispensable unit operation in coal preparation [2], [3].

For an efficient coalscreening process, the kinetic properties of screen body should accord with the law of coalscreening principle. As we know, the blinding of apertures with nearmesh coal particles is inevitable in practice and can affect the other particles passing through the screen surface. For the traditional large vibrating screen ...

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

One of the most widely used screening technologies for steam coal preparation after removal of fine fractions, is a 6 mm screening method. We propose a novel variableamplitude equalthickness elastic screen (VAETES) to solve the problem of material accumulation and screen aperture blockage during the 6 mm screening process of steam moist coal.

The understanding of screening process is incomplete regarding the intricacies of particleparticle and particlemachine interactions. But the influence of these interactions on the screening process effects on both the efficiency and the value of the product (Soldinger 2000; Zhao et al. 2000; Jiao et al. 2006).We divide the screening process into four parts as follows: (1) looseness: the void ...
