Introduction to efficient coal preparation process

Feeding in pressurized or non-pressurized feed two or three product HM cyclone for the host, without using desliming Process -50mm grain size of the original coal, the use of small diameter -0.5 mm slime heavy medium cyclone, The system is equipped with auxiliary equipment such as linear de-screening, centrifugal dehydrator, magnetic separator, automatic filter press, and automatic suspension medium density control device to form a heavy medium-weight high-efficiency coal preparation process. This process is suitable for difficult coal selection, especially high sulfur difficult to select coal. The process system is simple, the sorting precision is high, the adaptability is strong, the product quality is stable, the sorting density is controllable, and the operation and management are convenient. Another feature of the process is the effective removal of inorganic sulfur having a particle size lower limit of less than or equal to 0.045 mm. Whether or not flotation is employed is determined based on the number of masses of -0.045 mm. For the 150mm grain class, a dynamic sieve jig can be used for mechanical drainage.

Taking SKT jig as the main machine, the non-de-sludge process is used to treat -0.5mm granular raw coal, and the -0.5mm slime is combined flotation. The system is equipped with auxiliary equipment such as linear dewatering screen, centrifugal dewatering machine and automatic filter press. , the formation of jigging-flotation efficient coal preparation process. This process is suitable for easy selection to difficult coal selection. The process system is simple, the sorting precision is high, the adaptability is strong, the sorting density is controllable, and the operation and management are convenient.

The main machine of the moving sieve jig is used to process 300-25mm granular raw coal. The system is equipped with auxiliary equipment such as linear de-screening and automatic filter press to form a high-efficiency coal preparation process for moving sieve and jigging. This process is suitable for dynamic coal sorting. The process system is simple, the sorting precision is high, the adaptability is strong, the product quality is stable, the sorting density is controllable, and the operation and management are convenient.
