Embodiment Construction

[0019] see figure 1 , 2 , 3. The present invention has front and rear positioning plates 1 and 4, and there are many dielectric rods 3 (generally 1-3 thousand) densely distributed between the two positioning plates, and the outer wall surfaces of one or two front and rear positioning plates 1 and 4 Three fixed ears 2 are welded on the upper part, especially: the dielectric rod 3 is a magnetically conductive stainless steel threaded screw rod, and its outer surface has thread serrations (multiple axial grooves can also be provided, or made into waves, etc., Forming a sawtooth structure), when installed and used, the density increases gradually from the inside to the outside. Generally, the vertical and horizontal arrangement spacing of the dielectric rods can vary within 1-6mm; the arrangement density of the dielectric rods 3 on the positioning plate increases gradually from bottom to top.

[0020] The magnetic stainless steel rod described in this embodiment has a diameter o...

Abstract

The invention relates to parts of preparation equipment, and is a gradient sawtooth magnetic medium box for a high gradient magnetic separator, comprising a front positioning plate and a rear positioning plate, wherein a plurality of medium rods are densely distributed between the front positioning plate and the rear positioning plate, and at least one fixing lug is welded at the outer wall surface(s), close to the upper part, of one or two of the front and rear positioning plates. The gradient sawtooth magnetic medium box is characterized in that the medium rods are magnetic guide stainless steel rods, the outer surfaces of the medium rods are in a sawtooth structure, and the arranging density of the medium rods on the positioning plates is increased in a gradient mode from bottom to top. According to the invention, the main problems such as large reluctance, high power consumption and unsmooth ore discharge of the existing magnetic medium box are solved, and the gradient sawtooth magnetic medium box is mainly used for the high gradient magnetic separator of metallurgy preparation equipment.

Description

technical field [0001] The invention relates to components in mineral processing equipment, in particular to a gradient sawtooth type medium box for a high gradient magnetic separator. Background technique [0002] The separation ring of the high-gradient magnetic separator has 24 to 128 magnetic media boxes evenly distributed on the surface of the drum according to the diameter of the rotating ring. The commonly used magnetic media boxes include mesh media and round rod media. Mesh media has a better effect on recovering fine ore particles, but it is rarely used due to the phenomenon of "magnetic short circuit" between media and easy clogging. [0003] Chinese patent 200610132431.9 discloses a manufacturing method of a round bar magnetic medium for a high-gradient magnetic separator. The magnetic medium consists of 1 to 2 thousand dielectric rods evenly arranged between two positioning plates at an interval of 2 to 5 mm. Generally, it is made of Cr series magnetically cond...
