It is praised as the most advanced &quot;high-efficiency and high-quality&quot; coal preparation plant with the most advanced technology and technology in China. In terms of comprehensive analysis, the main advantages of Ushita coal preparation plant are:</p><p><br/></p><p>1. High yield of clean coal. Ushitai Coal Preparation Plant adopts a graded washing process. Raw coals with different thickness adopt different sorting densities and process parameters to achieve effective sorting, effectively improve the effect of heavy medium cyclone sorting, and maximize product production rate. The yield of clean coal will increase by 1 to 1.5%, and the annual increase in profit will reach 10 million yuan.</p><p><br/></p><p>2. Low energy consumption. The dual-source pressure less three-product heavy-medium cyclone has the characteristics of high sorting efficiency, low supply medium pressure and small amount of suspension circulation. Compared with the single-source cyclone, the supply pressure can be reduced from 0.3 MPa to 0.15 MPa, and the dielectric power consumption can be reduced by 1 Kw·h.</p><p><br/></p><p>3. Low consumption. After being graded and washed, 50~3mm thickness products are removed by vibrating screen. Compared with the non-grading and sorting technology, the unit processing capacity and the stripping efficiency are improved.</p><p><br/></p><p>4. Reasonable simplification of the process system and large-scale equipment, reducing the number of equipment and equipment are easy to do production management and maintenance. The reduction in the number of equipment reduces the total investment in the early and late periods. The use of a graded washing process can reduce the investment by 20% over the mixed washing investment.</p><p><br/></p>
