Dry pair roller strong magnetic separator

Abstract

The present invention proposes a dry double-roller strong magnetic separator, which includes a supporting frame, a transmission chain, and a feeding hopper arranged on the top of the supporting frame. At least two sets of relatively parallel toothed magnetic poles are wound on the electromagnetic roller, and the left and right sides of the electromagnetic roller are provided with unloading bearing seats, and the unloading bearing seats are provided with unloading brushes that match the toothed magnetic poles A discharge hopper is provided below the electromagnetic roller, and the electromagnetic roller drives the unloading brush wheel to rotate through the auxiliary sprocket assembly and the transmission chain arranged on the support frame. The dry-type double-roller strong magnetic separator of the present invention adopts the paired structure magnetic system and the tooth-shaped magnetic pole effect of the electromagnetic roller to increase the magnetic penetration depth, the magnetic field gradient is high, and the magnetic induction intensity of the magnetic separation area can reach 2.5T; the separation effect is good, It can sort dry and fine materials without environmental pollution.

Description

technical field [0001] The invention relates to mineral processing equipment, in particular to a dry double-roller strong magnetic separator. Background technique [0002] my country is rich in non-metallic ore and coal resources, but overall there are few high-grade ore and many low-grade ore. At the same time, due to the continuous improvement of users' consumption and quality of high-quality non-metallic minerals and coal mine products, such as: ceramics, papermaking, and paint industries have requirements for the whiteness of potassium albite feldspar and kaolin; power plants desulfurize coal powder before combustion to reduce environmental pollution , Improve the combustion efficiency of pulverized coal, there are still many deficiencies in many aspects of dealing with weak magnetic mineral impurities, thus forcing the magnetic separation equipment for impurity removal and storage to be continuously improved and perfected. [0003] At present, magnetic separation equip...

Problems solved by technology

The main features of this type of equipment are good separation effect, high magnetic field strength, and the magnetic field can reach more than 1.0T. The disadvantage of the equipment is that it needs supporting water addition and dehydration process, the process is complicated, the production line occupies a large area, consumes water and electricity, the cost is high, and the tailings are difficult to treat and put into production.
