Superfine wollastonite powder magnetic-attraction vibrating screening device

Abstract

The invention discloses a superfine wollastonite powder magnetic-attraction vibrating screening device comprising a machine body. A screen net is arranged inside the machine body. Multiple vibrators are arranged at the bottom of the screen net. A reinforcing ring plate is fixedly arranged on the outer ring of the screen net. Multiple extension plates are circumferentially arranged on the outer ring of the reinforcing ring plate. The tops of the extension plates are provided with first permanent magnets. A feeding pipe is installed in the middle of the top of the machine body. A hopper is arranged at the upper end of the feeding pipe. A material conveying shaft is arranged in the middle of the inner side of the feeding pipe. The inner side of the feeding pipe is further provided with a spiral blade located on the material conveying shaft. The upper end of the material conveying shaft is connected with an output shaft of a second transmission. The input end of the second transmission isconnected with a lower output shaft of a double-extension motor. An upper output shaft of the double-extension motor is connected with an input shaft of a first transmission. An L-shaped support rod is installed on an output shaft of the first transmission. A second permanent magnet is installed at the lower end of the L-shaped support rod. The superfine wollastonite powder magnetic-attraction vibrating screening device is novel in structure, good in screening and filtering effect, high in efficiency, so that the wollastonite powder can be reliably used.

Description

technical field [0001] The invention relates to the technical field of vibration screening equipment, in particular to an ultrafine wollastonite powder magnetic suction vibration screening device. Background technique [0002] The composition of wollastonite is Ca3, triclinic crystal system, usually in the form of flaky, radial or fibrous aggregates, white with grayish tinge, glass luster, and pearl luster on the cleavage surface. It is mainly produced in the contact metamorphic zone of acidic intrusive rock and limestone. It is the main mineral component of skarn, and it is also found in some deep metamorphic rocks. Wollastonite belongs to a kind of chain metasilicate, and it is also fibrous and needle-like. Because of its special crystal structure, its properties are determined. Wollastonite has good insulation, high whiteness, good dielectric properties, and high heat resistance and weather resistance. Wollastonite is widely used in ceramics, chemical industry, metallur...

AI Technical Summary

Problems solved by technology

[0003] Wollastonite powder has needle-like and fibrous crystal forms, high whiteness and unique physical and chemical properties. At present, it is necessary to screen bulk raw materials in the production of fine wollastonite powder. The structure of the current screening machine is relatively simple compared with the traditional one. When the dust overflows seriously, there are deficiencies such as low efficiency and poor screening effect
