Abstract
The utility model discloses an induced draft tower mill which comprises a vertical cylinder provided with a feeding hole and a discharging hole, and a plurality of pair rollers which are arranged in the inner cavity of the vertical cylinder and are driven by a power source, wherein the feeding hole is arranged at the bottom of the vertical cylinder, the discharging hole is arranged at the top of the vertical cylinder, the pair rollers are arranged at intervals from top to bottom, the diameters of two roller bodies of each group of pair rollers are different, the rotating directions are same, and the line rotating speeds are different; an induced draft selecting pipeline is arranged above the discharging hole, an air inlet of the induced draft selecting pipeline is positioned above the feeding hole, and selecting outlets are arranged on the pipe wall of the induced draft selecting pipe from top to bottom. The utility model improves the milling efficiency and the regularity of the milled material shape, thereby improving the output of the product. The induced draft selecting pipeline is arranged above the discharging hole, the granularity of needed materials is selected by adjusting the induced draft amount.
Description
Technical field
The utility model relates to pulverizer, especially relates to the air inducing tower mill.
Background technology
Present known pair roller type pulverizer, the direction of rotation of two roll body is rotation in opposite directions, and with same linear velocity rotation, by extruding reaches the pulverizing purpose to material, the material shapes irregularity after therefore pulverizing has directly influenced product quality.And the raw meal particle size after once pulverizing is bigger, if reach than small grain size, need thick material told and back fail in the machine pulverizing repeatedly more repeatedly, so the disintegrating process path length, power consumption is many, efficient is low.
The utility model content
The air inducing tower mill that provides a kind of crushing efficiency high is provided the utility model purpose
For achieving the above object, the utility model can be taked following technical proposals:
Air inducing tower mill described in the utility model, it comprises upright and the pair roller of chamber by drive power source that set within it that offers the charging and discharging mouth; Described charging aperture is arranged on the bottom of upright tube; Described discharging opening is arranged on the top of upright tube; Described pair roller is many groups that are provided with at interval from top to bottom; Identical and the linear velocity difference of diameter difference, the rotation direction of two roll bodies in every group of pair roller; Be provided with the air inducing pipeline of selecting materials above discharging opening, the select materials air inlet of pipeline of described air inducing is positioned at the top of charging aperture, offers the outlet of selecting materials downwards on air inducing is selected materials the tube wall of pipeline.
For realizing that classification selects materials, it is a plurality of for what be provided with at interval to be opened in the outlet of selecting materials that described air inducing selects materials on the pipe wall; Air-introduced machine is arranged on the air inducing pipe end of selecting materials.
The utility model advantage just is to take that two roll bodies are set to diameter difference, identical, different these technical schemes of rotating speed of rotation direction in every group of pair roller; Therefore in to the material crushing process, the material power effect that not only is squeezed is because the speed difference of two roll bodies makes material also be subjected to the grinding pressure effect that two roll body contact-making surfaces are produced, therefore after once pulverizing, can obtain the less material of granularity, improve crush efficiency.Rolling of material also improved the regularity of crushing rear material shape, thereby improved product quality.Above discharging opening, be provided with the air inducing pipeline of selecting materials, can choose the granularity of required material by regulating air inducing amount size like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, air inducing tower mill described in the utility model, it comprises upright 3 and the pair roller of chamber by drive power source that set within it that offers charging and discharging mouth 1,2; Described charging aperture 1 is arranged on the bottom of upright tube 3; Described discharging opening 2 is arranged on the top of upright tube 3; Described pair roller is three groups that are provided with at interval from top to bottom; Identical and the linear velocity difference of diameter difference, the rotation direction of two roll bodies 4,5 in every group of pair roller; Above discharging opening 2, be provided with the air inducing pipeline 6 of selecting materials, described air inducing select materials the air inlet 7 of pipeline 6 be positioned at charging aperture 1 directly over, spaced apart on air inducing is selected materials the tube wall of pipeline 7 be provided with two outlets 8 of selecting materials downwards; Air-introduced machine 9 is arranged on air inducing pipeline 6 ends of selecting materials.
