Automatic sundry removal material extrusion double-roller machine

Abstract

The invention relates to an automatic sundry removal material extrusion double-roller machine, which comprises a machine frame, a feeding hopper, a material collecting hopper and two extrusion rollers, wherein the material collecting hopper is arranged under the feeding hopper; the two extrusion rollers are embedded at the lower part of the feeding hopper in a way capable of oppositely rotating; the two ends of the two extrusion rollers are connected with the machine frame; each of the two extrusion rollers is in a cylindrical shape; a plurality of extrusion strips are uniformly distributed on the surface of each extrusion roller; each extrusion strip is welded on the corresponding extrusion roller; when the two extrusion rollers rotate, the extrusion strips which approach to each other always maintain the engaged state; sundry removal cabins are arranged at two sides of the feeding hopper; and a permanent magnet is arranged in each sundry removal cabin. Compared with the prior art, the automatic sundry removal material extrusion double-roller machine has the advantages that sundries can be automatically removed; the service life is long; and the cost is low.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to an automatic impurity-removing material extrusion double-roller machine. Background technique [0002] At present, the batching processing equipment for lead-containing materials or raw ore in the lead smelting industry is a pulverizer. Although its manufacturing cost is low, the pulverization noise is large and the service life of the equipment is short. The prior art also has the use of powder to roll forming machines. Because when the lead-containing material or raw ore particles are larger than the gap between the cylinder and the roller, the powder material roller forming machine cannot exert its efficiency at all, so its powder making rate is only 60% to 70%. If the processing principle remains basically the same, mainly through measures such as increasing the diameter of the extrusion roller, improving the material, and reducing the speed of the extrusion rolle...

AI Technical Summary

Problems solved by technology

Because when the lead-containing material or raw ore particles are larger than the gap between the cylinder and the roller, the powder material roller forming machine cannot exert its efficiency at all, so its powder making rate is only 60% to 70%.

If the processing principle remains basically the same, mainly through measures such as increasing the diameter of the extrusion roller, improving the material, and reducing the speed of the extrusion roller to increase the milling rate of the lead-containing material or raw ore, the cost is expensive, the volume is large, and it is too Bulky, high power consumption, high processing costs, high maintenance costs; moreover, iron-containing impurities are often mixed in the raw ore, causing serious damage to the milling equipment
