Abstract

The invention relates to a novel taper vertical mill, consisting of a body (1) and a crushing chamber (2) which is positioned at the bottom end of the body (1), a rotor (7), a charge inlet and a discharge outlet are arranged in the crushing chamber (2). The novel taper vertical mill is characterized in that: the rotor (7) is single layer structure or structure with two or more layers, a plurality of hammerheads (9) are arranged at the rotor (7), the hammerheads (9) are distributed and arranged at the edge of the rotor (7), an intra cavity wall in the crushing chamber (2) is inclined, and a tilting grinding disc (24) is formed; a backlash d is arranged between the hammerhead (9) and the grinding disc (24), an inclined plane discharge channel (10) is formed, a rotor (5) is connected with a drive mechanism by a rotating shaft (3), the upper end and the lower end of the rotating shaft (3) are connected with the body (1) by a bearing (31, 32); an inclined working plane is formed between the rotating rotor (7) and the grinding disc (24). The discharge channel of the invention can not be blocked by blocky crushed aggregates caused by seeper, thus discharging speed is fast and efficiency is high. The service life of the hammerhead and complete appliance is prolonged. The effects of saving material, electricity, and energy conservation are realized.

Description

technical field [0001] The invention relates to a material grinding equipment, in particular to a conical vertical mill, which is the fifth-generation vertical mill with multiple structural improvements. It belongs to the technical field of material grinding equipment. Background technique [0002] Ball mill is currently the most widely used grinding equipment, but its grinding efficiency is low and the grinding effect is poor. The roller mill and vertical roller mill developed later have improved grinding efficiency, but the finished product is needle-shaped, which deteriorates product performance and is not suitable for final grinding. [0003] The invention with application number 02115262.4 discloses a conical material bed vertical mill, which is characterized in that it is composed of a machine body, a rotor and a wind power control device. The material bed and the high-speed rotating rotor drive the extrusion head to extrude the material in the conical material bed. ...
