Abstract

The utility model relates to a vertical mill which comprises a groove body, a frame, a grinding wheel, a main axis, a draw bar, a millstone, an electric machine and a drive pair, wherein the groove body is fixed at the frame, the millstone is arranged at the bottom of the groove body, a wheel edge of the grinding wheel is pressed on the millstone, a shaft of the grinding wheel is glidingly coated with the main axis which is positioned at the middle of the groove body and is perpendicular to the bottom of the groove body by an axle-box; the main axis is rotatablely connected with the groove and the frame, and rotatablely connected with an axis of the electric machine by the drive pair; one end of the draw bar is connected with the main axis, and the other end is hooked with an axis end which is positioned at the other side of the grinding wheel; a water intake and a discharge opening are respectively arranged at the upper part and the lower part of a vertical wall of the groove body. Through the grinding wheel mills on the millstone, the utility model greatly increases grinding efficiency and reducing noise and cost; grooves which are distributed at the millstone are capable of preventing ores slide; an external wheel sleeve of the grinding wheel takes the knock-down structure, thereby making maintaining conveniently, and the grinding type minishes friction reduces medium loss and effect for the qualities of the ores.

Description

Vertical grinding mill

Technical field

The utility model relates to a kind of size reduction machinery, particularly a kind of vertical grinding mill.Be mainly used in grinding to ore.

Background technology

General now employing ball mill carries out grinding to ore, as abrasive media ore is carried out impact friction by spheroid, thereby reaches the purpose of grinding, and this breaking method efficient is very low, and noise is big, production cost is high.

Summary of the invention

The purpose of this utility model just provides a kind of high efficiency, noise is lower, production cost is low vertical grinding mill.

The technical solution of the utility model is: comprise cell body, frame, emery wheel, main shaft, draw bar, mill, motor, transmission, cell body is fixed on the frame, on mill is positioned at the bottom of the cell body, the wheel rim of emery wheel is pressed on the mill, the rotating shaft of emery wheel by the axle sleeve slip cap be positioned at the cell body center and with the main shaft of its bottom vertical on, this main shaft and cell body and frame are rotationally connected, and are in transmission connection by transmission and motor shaft; One end of draw bar is connected with main shaft, and the axle head of the other end and described emery wheel opposite side articulates; Upper and lower at the wall of cell body has water inlet and discharging opening respectively.

Middle part projection at the bottom of the described cell body, described mill are annular disk and place between cell body wall and the projection the annular end; Described discharging opening position is a little more than the upper surface of mill.

Described transmission comprises: reduction box, driving bevel gear, passive bevel gear, connecting axle, the power shaft of reduction box is connected with the axle of described motor, output shaft is connected with connecting axle one end, driving bevel gear is connected the other end of this connecting axle, and passive bevel gear is connected with the driving bevel gear engagement and with described main shaft; Main shaft is connected with described cell body and frame by bearing; The connecting axle of driving bevel gear is connected with frame by bearing, and passive bevel gear is positioned at an oil tray.

Described emery wheel has 2-6, is distributed on the described mill, overlaps mutually nested the composition by interior wheel body and foreign steamer, and both connect by screw.

The utility model rolls on mill by emery wheel, has improved crush efficiency greatly, has also reduced noise and production cost; Grooves distributed can prevent that ore from sliding on mill; The foreign steamer of emery wheel cover is demountable structure, greatly facilitates maintenance, has reduced friction and roll grinding mode, has reduced the loss of abrasive media and to the influence of ore quality.
