Embodiment 1
[0022] Weigh 90.7% iron powder, 8.5% kaolin and 0.8% graphite for batching according to mass percentage, mix them evenly through a mixer, and put them into a spherical mold for later use. The material used for each pellet is about 10g, and the punching machine is automatically controlled Feed the material, set the stamping time each time, automatically complete the pressing of the ball blank in the spherical mold, place the ball blank on the ceramic base, put it on the conveyor belt, and enter the continuous heat treatment furnace for sintering. The maximum sintering temperature is 1000°C. Sinter at the highest temperature for 1 hour to obtain jigging medium pellets.

Abstract
The invention relates to a jigging medium ball for jigging and a preparation method thereof, and belongs to the technical field of oredressing. The jigging medium ball comprises iron powder, carbon powder, glass powder, a binding agent and a lubricating agent. The preparation method comprises the following steps of: uniformly mixing the iron powder, the carbon powder, the glass powder, the binding agent and the lubricating agent; putting into a ball-shaped mould; placing the ball-shaped mould at a punching position of an automatic punching machine; automatically finishing punching a ball billet by using the automatic punching machine; and sintering the ball billet in a continuous heat treatment furnace at the temperature of between 300 and 1,100 DEG C for 1 to 20 hours so as to obtain the jigging medium ball. The medium ball prepared by the method has controllable density and overall dimension, has high concentrate recovery rate, high efficiency and lowered bed stone offset during jigging, has a simple preparation process and low cost, and is applicable to industrial production.
Description
technical field [0001] The invention relates to a jigging medium pellet used for jigging ore dressing and a preparation method thereof, belonging to the technical field of ore dressing. Background technique [0002] Jig beneficiation refers to the relative transfer of mineral particle mixture under the action of vertical pulsating medium flow, and the relative transfer of particles with different densities under the action of static pressure difference and sedimentation velocity difference, and finally realizes the separation of light and heavy minerals, and discharges separately to obtain concentrate and tailings. Jig beneficiation is an important method for processing coarse, medium and fine-grained ores with simple process operation, large equipment processing capacity and low production cost. However, at present, the jigging materials used in traditional jigging beneficiation are all natural ores, such as pyrite after crushing. Due to the irregular shape and size of nat...
