Vertical roller mill reconstruction

The inner tube separator extend technological status quo because the original design of the mill ATOX50 separator back pink inner tube and position the disc space is relatively high, so that the rising air vents ring the center of the swirl of negative pressure caused disorder, separator machine selection powder feed meal back twice brought up by higher vertical roller mill pressure, increase the amount of circulating meal appears separator blade wear and inner wear over-grinding phenomenon, poor efficiency separator. Technical innovation in order to collect back as far as possible within the circulation coarse grinding into the disc again qualified powder, reducing material in the grinding cycles, plus the original inner cylinder port position based on the actual space inside the mill down. Pressure drop effect of the mill, separator speed, power consumption has declined, Taiwanese mill increased by about 20t / h. 3, the scraper blade head cavity technological status quo Vertical roller mill spit large amount of slag circulation and uneven particle size, plus iron raw materials used in steel slag ingredients, wear scraper blade chamber head is very serious. A new pair of squeegee head life cycle is only about two weeks, the wear and tear of the scraper strip so effectively reduce scum outer loop, the main motor load is relatively high, and the replacement of the blade head can cause human and material resources and waste extend the maintenance time. Technological transformation in the double-sided blade head affixed UP board to increase the durability and the overall strength of the blade. Effect engineered squeegee head life cycle is greatly improved, increased from the original two weeks to about three months or more, which saves a lot of maintenance time, while saving manpower, material resources, effectively improve the mill operation cycle.
