Slag vertical mill is a negative pressure air sweeping type grinding equipment, which will dry the slag and grind the slag.
The slag ground by the grinding roller on the grinding disc is composed of two parts: a small part of new slag with high water content and most of the ground non-finished slag with lower water content. This part of non-finished slag is the coarse material returned after separation by the separator because of the larger particles. The strong negative pressure wind caused two parts of slag to fall onto the grinding disc.
Under the action of centrifugal force, the slag is guided to the auxiliary grinding roller, and the slag is compacted by reducing the blowing of the auxiliary grinding roller. The auxiliary grinding roller keeps a certain distance from the grinding disc, and is fixed on the rocker arm with very light weight.
The main grinding roller is fixed on the thicker main rocker arm, and the configured material layer is ground by pressure grinding. The force is generated by the weight of the grinding roller itself and the pressure of the hydraulic system.
The grinding roller rotates by rubbing against the abrasive bed. The sensor and buffer limit device installed on the rocker arm can prevent direct metal contact between the grinding roller and the grinding disc.
The ground slag particles are thrown out by the centrifugal force and flow through the retaining ring. Here it is captured by the airflow rising through the wind ring, and the dust and gas flow through the grinding chamber, so that it is surrounded by the vertical grinding cylinder equipped with wear-resistant lining and enters the powder separator. The powder separator is installed or welded on the vertical mill barrel.
Without the help of auxiliary transmission, the vertical mill can be directly loaded and started by the main motor under the condition of loading (after a short shutdown). In order to unload the main motor, the grinding roller is hydraulically lifted to reduce the pressure of the hydraulic system. The oil can be introduced into the rodless cavity of the hydraulic cylinder.
