Description
Technical field
The present invention relates to ball mill equipment technical field more particularly to a kind of spring capping formula charging ball mill apparatus.
Background technique
When laboratory ball mill works, the ore materials of certain partial size are fitted into ball mill cylinder by feeding device, are led to
It crosses specific movement to smash and grind ore materials by the steel ball in ball mill cylinder, is allowed to partial size and is constantly refined,
To be used for subsequent chemical analysis of mineral；The feeding device requires charging door after charging, and gland and pressure pad are to described
Charging door has certain pressing force, seals the charging door well.Currently, laboratory ball mill cylinder is mostly monotubular
Formula, ball mill cylinder, which is mounted on the rack, drives its rotation by belt pulley, so that the steel ball in ball mill cylinder is to ball milling machine barrel
Interior ore is ground, and under normal circumstances, ball mill cylinder cannot be dismantled.
Such as Fig. 1, the feeding device of laboratory ball mill, generally by charging door gland 3 and hold-down bolt 1 and charging cage
5, the parts composition such as right plug 6, charging lid pressure pad 7；The outer spiral shell of internal screw thread and hold-down bolt 1 in the centre bore of charging door gland 3
Charging door gland 3, is inserted into the spline of 4 shell of ball mill cylinder by line connection, and then rotation sticks into it in ball mill cylinder 4
Inner walls, and 1 front end of hold-down bolt heads into the inner hole of charging cage 5, charging cage 5 connects with right plug 6, charging lid pressure pad 7
It connects and is pressed at 4 right end feed inlet of cylinder, be allowed to seal；This feeding device is the spiral shell by hold-down bolt 1 and charging door gland 3
Line connection charges to make hold-down bolt 1 form axial movement (charging door gland 3 is motionless because cylinder inner wall mouth limits) to adjust
Cage 5 and right plug 6 compress it to the aperture of 4 right end of cylinder.There are two disadvantage, disadvantages one: charging cage 5 and the right side for this device
Plug 6 needs square toes one end with the tool holders such as spanner hold-down bolt 1 when aperture compresses and unclamps, and then carries out positive or anti-
It is relatively elaborate and need third party's tool to rotation；Disadvantage two: due to being that screw thread rotation compresses and release, rotation are turned around only
The stroke of one screw pitch, so that hold-down bolt 1 needs to rotate, a few could compress charging cage 5 and right plug 6 or release is taken out,
It is inefficient.
In addition, since current laboratory ball mill is all made of single-cylinder type, under normal circumstances, when in addition to repairing, experiment
Cylinder is non-removable to room ball mill during normal operation.Since ball mill cylinder needs frequently charging and discharging, every time
The interior meeting adhesion of cylinder remains some ore materials after grinding discharging, will affect what different ore materials below carried out after grinding in this way
Analysis of components result；So ball mill cylinder needs in laboratory are often cleaned, to guarantee each tribolite constituent analysis
Accuracy.But because of cylinder under normal conditions non-dismountable, therefore cylinder is carried out directly on ball mill using external water pipe
Inner wall rinses, troublesome in poeration and have biggish pollution to indoor environment.
Summary of the invention
In view of this, the embodiment provides the spring pressures that one kind can efficiently and readily open its charging door
