Description

The invention relates to the grinding equipment of enrichment plants, for example, in non-ferrous metallurgy.

A device for loading rods into rod mills is known, comprising a frame, a frame, an arrow and a tilting table with rods held on its surface by means of elastic bonds Cl.

This device is complicated in design, since in addition to moving the cart-table along the boom, additional pneumatic or hydraulic cylinders are needed to rotate the table on the boom.

According to its technical essence, the closest to the invention is a device for loading rods into a rod mill, which contains a roller table located at the throat of the mill, the support rollers of which form a tray for receiving a package of rods G23.

In the said device, a pusher and a crank mechanism with a drive are used to move the rods.

The disadvantage of this device is low productivity due to the single-piece feeding of the rods into the mill.

In addition, the performance of this device is low and is associated with the presence of reverse idle strokes of the mechanisms that feed the rods into the mill.

The aim of the invention is to simplify the design and increase productivity.

This goal is achieved by the fact that in the device for loading rods into a rod mill containing a roller conveyor placed at the throat side of the mill, the support rollers of which form a tray for receiving a pack of rods, the roller table is equipped with traverses for fastening it in the neck at an acute angle to the longitudinal axis of the mill , at the same time, a transverse rotary latch is mounted in the transverse section, and above the tray, at a distance from the end rollers of the roller table, not exceeding 0.25 the length of loading the 25th rod, a supporting roller is mounted,

Tray rollers can be set at an angle of 60-65 to each other.

FIG. 1 shows a longitudinal

30 slit mill mounted on

ycTpoactBOM for e-loading the rods in FIG. 2 shows section A-A in FIG. one.

The device includes a conveyor 1, mounted on the frame 2. The frame 2 through the traverse 3 is suspended on the neck 4 of the mill 5. The rollers b of the roller table 1 form a tray and are mounted under the coal 60-65 to each other. The latch 7 is installed in the device before entering the neck and is made rotatable.

The support roller 8 is mounted above the roller table from the mill side at a distance not exceeding 0.25 of the rod length from the end roller 9 of the roller table. The conveyor device is installed obliquely to the axis of the mill.

Before loading the rods, the device is supplied by the workshop crane to the mill and secured through the cross beams 3 to the neck 4. Then the rod packet is fed to the roller table 1. The rods held by the latch 7 lie on the roller table.

After the service personnel opens the latch, the rods, under the action of their own weight, will go off along the rollers 6 of the inclined roller table into the mill.

When the center of gravity of the rods has passed the last roller, the rods with the rear end will begin to tear off the rollers of the roller table and rest against the support roller 8, which will prevent the rods from falling prematurely with the front end into the mill.

The distance from the last roller 9 of the roller table to roller 8, not exceeding 0.25 of the rod length, is sufficient for placing the rods in the mill.

The rods are laid on the roller conveyor console. If necessary, the rods can be reported initial movement.

After the package of rods is loaded into the mill, the latch closes and the device can again accept the package of rods. After the rods are loaded, the device is dismantled.

Mechanized loading significantly improves the working conditions of maintenance personnel and complies with safety regulations for enterprises and organizations of the metallurgical industry.
