The invention provides a spiral stirring mill for sepiolite The spiral stirring mill mainly solves the technical problems that an existing sepiolite grinding machine is low in grinding efficiency, not thorough in grinding and the like According to the technical scheme, the spiral stirring mill is characterized by comprising an outer barrel (1) and a spiral cone (2), wherein the spiral cone (2) is arranged in the outer barrel (1); the small end of the spiral cone (2) is arranged at one end of an inlet of the outer barrel (1); and the large end of the spiral cone (2) is arranged at one end ofan outlet of the outer barrel (1) The spiral stirring mill is mainly applied to sepiolite crushing

Spiral stirring mill for sepiolite

The invention discloses a spiral cone stirring ball grinding mill. The spiral cone stirring ball grinding mill comprises a mill body, a driving device, a slewing bearing, a movable cone device, a fixed cone device and multiple grinding balls, wherein the slewing bearing, the movable cone device, the fixed cone device and the multiple grinding balls are arranged on the mill body. The driving mechanism can drive the movable cone device to rotate around the axis of the fixed cone device through the slewing bearing, and the grinding balls are placed in a cavity defined by the movable cone device and the fixed cone device jointly so as to carry out stirring and powder grinding on materials jointly. By means of the cooperation of the slewing bearing and the grinding balls, materials can be subjected to sufficient powder grinding, the effective work duration of the spiral cone stirring ball grinding mill is prolonged, the maintenance frequency can be reduced, and therefore the working efficiency and the powder grinding effect of the spiral cone stirring ball grinding mill can be greatly improved.
