Abstract
The utility model proposes mining ball grinding machine lining boards.Middle part is equipped with elongated rectangular cylinder liner plate on the cylinder of mining ball mill, both ends are respectively equipped with end cap liner plate and squeeze fixation, end cap liner plate is equipped with bolt hole and secures it within end cap by bolt, shell liner both ends of the surface are equipped with faceted pebble, so that shell liner and end cap liner plate form an entirety.The shell liner and end cap liner plate section are trapezoidal corrugated peace shape face, and for trapezoidal corrugated liner plate for roughly grinding, flat shape liner plate is used for fine grinding.Facing directly for liner plate end face is designed as faceted pebble using shell liner installation end cover lining plate again is first installed by the utility model, and the bolt for cancelling shell liner connects no screw hole, avoids leakage ore pulp, and easy access disassembly shortens the period of installation and maintenance.It is suitable for being used as mining ball grinding machine lining board.
Description
Technical field
Provided by the utility model is the cylinder accessory of machinery field ball mill, is mainly used in mining ball mill.Specifically
It is mining ball grinding machine lining board that ground, which is said,.
Background technique
Mining ball mill grinding process is divided into corase grinding and fine grinding, and mineral aggregate enters through charging gear first is inlaid with waveform liner plate
Coarse grinding cabin, when cylinder around horizontal axis turn round when, the intracorporal milling medium of cylinder and the mineral aggregate ground are in centrifugal force and frictional force
Under the action of, it is promoted by shell liner to after certain height, falls or leave since gravity disengaging barrel freely rushes down, make mine
Stone is crushed by impact and grinding and peeling effect；The impact that mineral aggregate is subjected to milling medium can strike on liner plate, be crushed again,
The impact effects that waveform liner plate generates are more preferably；Enter the fine grinding storehouse for being inlaid with flat liner plate by partition by the broken mineral aggregate of corase grinding,
It is more mellow and fuller that flat liner plate grinds mineral aggregate, is impacting and is gradually being crushed under abrasive action, the powder of generation passes through discharging
The discharge of grate plate, completes grinding operation.
Currently, mining ball grinding machine lining board is usually rectangular liner plate, with fastened by screw on ball mill barrel.Shell liner top
End cap liner plate, when installation obtain first peace end cap liner plate and pacify shell liner again, installation period is long, and when maintenance is not easy to disassemble, cost compared with
It is high.Due also to liner plate, than relatively thin, easy to break after liner plate edge abrasion, fastening screw is easy to fall off, and at cylinder screw hole
Leakiness ore pulp, is easy to happen equipment breakdown.
Summary of the invention
In order to shorten mining ball grinding machine lining board installation and maintenance period, the utility model proposes mining ball millings
Machine liner plate.The liner plate solves lining by changing the erection sequence of end cap liner plate and shell liner and cancelling shell liner screw hole
Plate installation and maintenance shorten the technical issues of period.
The utility model solves scheme used by technical problem:
Middle part is equipped with elongated rectangular cylinder liner plate on the cylinder of mining ball mill, both ends are respectively equipped with end cap liner plate and squeeze
Pressing is fixed, and end cap liner plate is equipped with bolt hole and secures it within end cap by bolt, and shell liner both ends of the surface are equipped with faceted pebble, so that
Shell liner and end cap liner plate form an entirety.
The shell liner and end cap liner plate section are trapezoidal corrugated peace shape face, and trapezoidal corrugated liner plate is put down for roughly grinding
Shape liner plate is used for fine grinding.
Good effect first installs shell liner installation end cover lining plate again since the utility model uses,
Shell liner uses elongated overall structure, without disconnecting, facing directly for liner plate end face is designed as faceted pebble, and cancel cylinder
The bolt of liner plate connects no screw hole, avoids leakage ore pulp, and easy access disassembly shortens the period of installation and maintenance.It is suitable
Preferably it is used as mining ball grinding machine lining board to use.

Fig. 5 is flat shape lining-plate bolt hole sectional view.
In figure, 1. cylinders, 2. shell liners, 3. end cap liner plates, 4. bolts hole, 5. faceted pebbles, 6. trapezoidal corrugateds, 7. flat shapes
Face.
Specific embodiment
According to the figure, middle part is equipped with elongated rectangular cylinder liner plate 2 on the cylinder 1 of mining ball mill, both ends are set respectively
There is end cap liner plate 3 to squeeze to fix, end cap liner plate is equipped with bolt hole 4 and secures it within end cap, shell liner both ends by bolt
Face is equipped with faceted pebble 5, so that shell liner and end cap liner plate form an entirety.
The shell liner and end cap liner plate section are trapezoidal 6 peaceful shape face 7 of corrugated, and trapezoidal corrugated liner plate is used to roughly grind,
Flat shape liner plate is used for fine grinding.
Working principle of the utility model is:
Motor drives cylinder revolution by deceleration device, cylinder it is intracorporal by ore grinding material and milling medium when cylinder is turned round by
Frictional force and centrifugal force effect are taken to after certain altitude by liner plate due to gravity, and just generation, which leaves and rushes down, falls, and strikes
On liner plate, mineral aggregate is being impacted and is gradually being crushed under abrasive action.Pulverized mineral aggregate is discharged outside cylinder through discharge portion.Discharge
After mineral aggregate is classified out qualified products in spiral classifier, coarse sand is returned in ball mill by co-feeding device after continued powder
Mill.Continuously and uniformly feeding, mineral aggregate continuously and uniformly enter ball mill through co-feeding device to feeding machine, and the material being grated is in a steady stream
Constantly it is discharged from ball mill.
Liner plate includes end cap liner plate and shell liner, and end face is to face directly and using bolt fastening on the cylinder of ball mill.
Usually elder generation's installation end cover lining plate installs shell liner again, long construction period, and while overhauling is also not easy to disassemble, also easy at bolt hole
Leak ore pulp.Rectangular liners plate end face is faced directly and is changed to faceted pebble, shell liner is piece rectangle of strip and the screw for cancelling shell liner
Hole avoids leakage ore pulp, and handling is easy to put when installation, and shell liner puts certain altitude and pacifies the extruding of end cap liner plate, fastening end again
Cover lining plate screw, final shell liner and end cap liner plate form an entirety, are less prone to concentrated wear and fracture.Between gap
There are broken ball and slag filling to play a protective role cylinder.A clear gap is only needed to remove end cap screw i.e. by step when maintenance
It can.The installation and maintenance period is shortened, production efficiency is improved.
The characteristics of the utility model:
Since facing directly for liner plate end face is designed as faceted pebble, and the bolt for cancelling shell liner connects no screw hole, keeps away
Leakage ore pulp is exempted from, easy access disassembly shortens the period of installation and maintenance.
