Vertical mill grinding technology has more advantages

Slag, steel slag grinding technology, main roller ball mill combined grinding, pre grinding vertical mill + ball mill grinding, grinding mill. Among them, grinding process is simple, less land occupation, low construction cost, high grinding efficiency, low energy consumption, slag, steel slag treatment technology is an ideal. In order to adapt to market demand, Tangshan Jidong based on the introduction of foreign advanced equipment manufacturing technology, through digestion and absorption and re innovation, independent R & D and manufacturing of 3.5 meters, 4.6 meters, 5.6 meters series of slag and steel slag equipment.

The following principle of slag, steel slag vertical mill: vertical mill use center feed and side feeding in two forms, material from the upper part of the air lock valve into the vertical mill, down into the feeding tube falls directly on the disc, with the disc rotate outwards, again by the feeding material scraping device of vertical pipe welding the scraping, was thrown into the grinding area disc lining board, roller grinding surface of grinding zone just above this. Grinding is grinding roller grinding material, non finished by a small part of the new material of high moisture and most grinding too has lower water composition. This part of the non finished because of coarse grain large powder selecting machine after separation by return, also is the circulation of material. Auxiliary grinding roller slag exhaust compaction. The main roller is fixed on the main rocker, pressurized by the abrasive layer configured. The force is generated by the self weight and hydraulic system of roller grinding itself pressure. The grinding roller through the bed friction material and grinding and rotation. Installed on the rocker arm of sensor and buffer limit device can prevent the grinding roller and the grinding disc direct metal to metal contact. Effect of slag particles are milled under the centrifugal force to be thrown and through the barrier material ring, here is the airflow through the wind ring rise the collector. Dust and gas mixture flows through the grinding chamber, surrounded by the milling cylinder vertical it was fitted with a wear resistant lining board, enter the welding in vertical mill separator barrel body, powder selecting machine finished product will be elected. Through the annular air ring is composed of a discharge foreign bodies, and in the event of dynamic disorder, through the annular air ring into the grinding slag vertical mill cone, installed through the disc below the scraping plate, scraping to discharge, these two kinds of slag from gas tank after discharge, into the recirculation into the feeding tube again, grinding, powder selecting, until a qualified product.
