Abstract

The utility model discloses a feeding device for a vertical type ring mill. A material equalizing plate is installed at the top end of a main shaft of the vertical type ring mill, and a material sliding hopper is installed on the inner wall of the vertical type ring mill. An adjustable feeding cylinder is installed at the lower end of a feed hopper and provided with an adjusting handle. The feeding device for the vertical type ring mill has the technical advantages that the material equalizing plate is installed at the top end of the main shaft of the vertical type ring mill and rotates along with the main shaft, materials dropping from the feed hopper drop on the material equalizing plate, are thrown to a material stopping hopper along a material guide spoke under the effect of centrifugal force and then drop on a milling ring along the inclined surface of the material sliding hopper, so that the materials drop on the whole milling ring uniformly, the phenomenon of milling without the materials is avoided, the rate of finished products at a time is high, and energy is saved.

Description

Vertical ring grinding mill blanking device

Technical field

The utility model relates to a kind of vertical ring grinding mill blanking device.

Background technology

The blanking of current vertical ring grinding mill is, on the top of vertical ring grinding mill, trapezoidal platform of blanking is housed, material is accumulated in the inclined-plane along trapezoidal platform of blanking outer rim on trapezoidal platform of blanking and falls on rolling ring, because material is free-falling, material falls very inhomogeneous, when falling in a side when too much, material falls from the hammer wheel outside, can not be ground to by the hammer wheel, when falling very few in a side, during even without material, form empty mill, accelerate the wearing and tearing of rolling ring and hammer wheel, at the bottom of the one-pass finished rate, also cause energy dissipation.

The utility model content

The purpose of this utility model is to provide a kind of vertical ring grinding mill blanking device.

The technical solution of the utility model is, a kind of vertical ring grinding mill blanking device, be equipped with equal charging tray on the top of the main shaft of vertical ring grinding mill, at vertical ring grinding mill inwall, is equipped with and slips hopper, in the lower end of feed hopper, adjustable feeding cylinder is housed, the adjustment handle is housed on adjustable feeding cylinder.

All on charging tray, the guide spoke is being arranged.

Have sieve aperture slipping on hopper.

The utlity model has following technique effect, because the refining dish is equipped with in the upper end at the annular grinder main shaft, the refining dish rotates with main shaft, and the material fallen from hopper drops on the refining dish, under the effect of centrifugal force, along the guide spoke, be thrown on the backgauge bucket, then along slipping the hopper inclined-plane, fall on rolling ring, material drops on whole rolling ring very uniformly, has overcome the phenomenon of empty mill, the one-pass finished rate is high, saves energy.

The accompanying drawing explanation

Fig. 1 is B-B cross section view of the present utility model.

Fig. 2 is A-A cross section view of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of vertical ring grinding mill blanking device, be equipped with equal charging tray 4 on the top of the main shaft 2 of vertical ring grinding mill 1, at vertical ring grinding mill 1 inwall, is equipped with and slips hopper 3, adjustable feeding cylinder 5 is housed in the lower end of feed hopper 6, is equipped with on adjustable feeding cylinder 5 and adjusts handle 8; All on charging tray 4, guide spoke 7 is being arranged; Have sieve aperture 9 slipping on hopper 3.
