Abstract

The utility model relates to a machine crushing materials and milling the materials into flour, which is composed of a one-stage conical crushing section and a two-stage column flour milling section. The periphery of a machine body is coated with a silencing layer for proofing sound, the utility model overcomes the requirement that the existing column mill needs to crush the materials into small blocks through a plurality of crushing procedures in advance, and the materials can be directly conveyed into the machine to be crushed and milled into the flour after the materials are crushed. The machine has the advantages and effects of simple structure, low noise, low equipment investment, small occupation area, wide application scope, etc.

Description

A kind of flour mill

The utility model belongs to the milling equipment of industries such as metallurgy, mine, cement.

Existing milling equipment has ball mill, Raymond machine and the column mill that forms by the Raymond machine development, shortcomings such as the above two have that energy consumption is big, noise is big, equipment investment and occupied ground area are big, though column mill belongs to a kind of novel milling equipment, but certainly require the piece grain little to the charging material, must give and carry out fragmentation through multiple other disintegrating apparatus earlier, have the big shortcoming of noise equally.

The utility model purpose provides a kind of relaxing the requirement of charging material piece, can break novel flour mill pure and that powder grinds voluntarily, reduces mechanical noise simultaneously.

The utility model scheme is to improve to form on existing column mill basis, in the cylindrical shell 4 of vertical installation, main shaft 2 is equipped with at the center, main shaft connects Multi-layer rotary top 7, circumferentially uniform on each aspect of rotating disk by roller axle 10, float several rollers 6 are installed, 9, main shaft drives rotating disk, rotating disk drive roller axle and roller are around main axis rotation, each roller gets rid of outside under centrifugal action, and at the anti-wearing liner 5 of material and cylinder inboard wall, 8, effect produces the roller rotation of accompanying rotation motion down, impact and the crowded material that grinds, reach the pulverizing requirement, it is characterized in that before the post abrasive dust grinds section, being provided with reduction stage, to enter post mill section powder again through the broken pure cobbing that becomes to adapt to column mill work of the broken material piece of the blade of a sword grinds, reduction stage is different from that the cylindricality powder grinds section and 5 retentions of tapered structure control breaker roll 6 and taper bush have descending varied pitch, will expect the descending broken purpose of piece gradually to reach.

Be minimizing noise unofficial biography, be equipped with by the double wall envelope in flour mill cylindrical shell periphery and wrap up in the noise reduction layer 11 that the foam quieter material constitutes.

Advantage and effects such as the utility model is owing to adopt the taper fragmentation, and the cylindricality powder grinds the form that combines, and has simple in structurely, effectively reduces equipment investment and floor space, and is widely applicable.

Accompanying drawing provides an exemplary construction of the present utility model

This machine is ground by two-stage post abrasive dust and the one-level fragmentation constitutes.Main shaft on body, is associated with rotating disk by bearing block 3 vertical support on the main shaft, the one-level reduction stage is made up of two-layer breaker roll, and two, three grades of posts mill section respectively is made up of three layers of roller, and respective rollers is then respectively by single, the two stacked three stacked formations of closing of closing.Four rollers are arranged on each aspect, make the connection that becomes to float of roller and rotating disk by roll shaft.Gapped between roll shaft and roller hole for this reason, between centers gap, breaker roll hole is 1～1.5 millimeter, 10～25 millimeters between centers gap, roller hole, and cooperate the section configuration of the roll shaft on the section to be made into rhombus pin shape the roller hole, roll shaft.
