Summary of the invention

The present invention overcomes the deficiency that prior art exists, and provides a kind of volume little, the novel grinding mill that the speed of milling is fast, milling efficiency is good.

To achieve these goals, the present invention is by the following technical solutions: a kind of grinding mill, it is characterized in that: include motor, motor output rotation axis, discharging chamber, milling mechanism, conveying mechanism and cooling body, wherein milling mechanism includes the chamber of milling, be arranged on the rotating disc of milling in chamber, rotating disc is fixedly installed on motor output rotation axis, the described chamber of milling becomes six to 12 prisms, described rotating disc is circular, oblique being arranged on of rotating disc milled in chamber, rotating disc outer peripheral face and the gap between cavity wall of milling arrange, rotating disc is divided into low-pressure cavity and high pressure chest the chamber of milling, the end of the low-pressure cavity in the described chamber of milling is connected with discharging chamber, the mill end of high pressure chest in chamber is connected with conveying mechanism, described conveying mechanism includes conveyor chamber, carry leaf and carry motor, described conveyor chamber is tapered, the little head end of conveyor chamber connects with the high pressure chest in the chamber of milling.

By adopting such scheme, well solved originally can only by roll realize mill principle, grinding mill of the present invention is divided into high pressure chest and low-pressure cavity by the rolling disc high speed rotating chamber that makes to mill, material enters high pressure chest from conveyor chamber, thereby because making mutual frictional impact between material, the rotation of rotating disc reaches the effect of milling, entered low-pressure cavity by the powder after rolling from the gap of rotating disc periphery, finally from discharging chamber, drop out.

The further setting of the present invention is: described cooling water cavity is arranged on the periphery in the chamber of milling, on cooling water cavity, be provided with water inlet pipe and water outlet pipe, described motor output rotation axis along prism mill chamber shaft centre line position arrange, described discharging chamber arranges around motor output rotation axis, between discharging chamber and low-pressure cavity, connect along motor output rotation axis peripheral clearance, on discharging chamber, be provided with feed opening and steam outlet.

By the scheme of further setting, by cooling water cavity is set, can, to the chamber cooling of milling, make machine operational effect better like this, on discharging chamber, be provided with steam outlet in addition, prevent that like this steam of the material high temperature generation being milled from cuing open bad equipment.

Last setting of the present invention is: described prism is nine prisms, its width of all edges of described rotating disc is axially in a parallel set with the cavity wall of milling, the angle of the axis in rotating disc and the chamber of milling, between 60 degree-70 degree, is provided with feed hopper on described conveyor chamber.

By the scheme of further setting, make the milling efficiency of product better, wherein the prism chamber of milling is that the mill angle of axis in chamber and rotating disc and the chamber of milling of nine prisms draws by repeatedly calculating and realizing between 60 degree-70 degree, adopt such scheme can improve to greatest extent the speed of milling, milling efficiency is also best.

Newly be described in further detail originally practical below in conjunction with accompanying drawing.
