HIGH-PRESSURE PULVERIZER

摘要

Disclosed is a high-pressure pulverizer, which comprises a pulverizer body (1) and an electric motor (2). A high-pressure container (3) is arranged outside the pulverizer body (1). A sealed space is formed between the high-pressure container (3) and the pulverizer body (1). A feeding port (3a) is formed in an outer wall of an upper portion of the high-pressure container (3). The feeding port (3a) is in sealed communication with a feeding pipe of the pulverizer body (1) through a soft feeding joint (4). A discharging port (3b) is formed in an outer wall of a lower portion of the high-pressure container (3). The discharging port (3b) is in sealed communication with a discharging pipe of the pulverizer body (1) through a soft discharging joint (5). A bearing base (6) is arranged at the bottom of the high-pressure container (3). The pulverizer body (1) is mounted on the bearing base (6) through a shock pad (7). A connecting shaft (8) is movably inserted into the top of the high-pressure container (3) in a sealed manner. The upper end of the connecting shaft (8) is in transmission connection with an output shaft of the electric motor (2). The lower end of the connecting shaft is connected to a main shaft of the pulverizer body (1). When the pulverizer is operating, high-pressure inert media is provided in a sealed space between the pulverizer body (1) and the high-pressure container (3). The pressure of the inert media is greater than or equal to the pressure in the pulverizer body (1). The pulverizer is suitable for pulverizing materials such as coal and non-metallic ore.
