Problems solved by technology

[0004] During the grinding process, since the grinding media (steel balls) point contact with the ore in the way of throwing and falling, the contact area is small and the grinding efficiency is low; there will also be friction between the steel balls. Ineffective direct impact, resulting in self-consum...

Abstract

The invention discloses a compound pendulum type roller mill which is capable of increasing the grinding area and improving grinding efficiency, high in efficiency and low in consumption. The compound pendulum type roller mill comprises a swinging box, wherein a bottom plate of the swinging box is in an arc shape, and the swinging box is equally divided into two parts at bearing central shafts at the two ends so that the swinging box tends to be in a two-force balance state in the moving process. The swinging box is hinged to the two ends of a support through the bearing central shafts. Spring boosters are mounted on the ground and located on the two sides of the swing of the swinging box. The spring boosters and a driving device jointly drive the swinging box to conduct compound pendulum motion under resultant force. The driving device is a crank and rocker mechanism. A box body is divided into two or more working bins by partition plates. Each partition plate is provided with material fineness control and material passing holes. A grinding medium roll is placed in each bin and conducts curvilinear motion to grind and impact ore to be thin and broken.

Description

technical field [0001] The invention relates to ore crushing and grinding equipment used in metal and nonmetal mining industries, in particular to a compound pendulum roller mill. Background technique [0002] In the metal and non-metal mining industry, grinding equipment is often used to grind ore into powder. The existing grinding equipment is mainly a ball mill. The grinding energy consumption of the grinding equipment should account for more than half of the total production machinery consumption, but The maximum effective power of the ball mill does not exceed 6%. The existing ball mill uses a circular cylinder as the fuselage, and the grinding medium (steel ball) and the ore to be ground are installed in the cylinder, which accounts for about 25%-45% of the volume, and the cylinder is driven by a motor to rotate. Drive the steel ball up, and then rely on the gravitational potential energy of the steel ball to drop, impact and wear away the ore. The existing ball mill...
