Abstract

The utility model discloses a kind of rib corrugated liner, the circular arc of cross section lower end is consistent with the circular arc of cement mill cylinder inner tube wall, including integrally formed corrugated working face and lateral side baffle；Fixation hole is equipped in the middle part of the corrugated working face, the lateral side baffle side is corrugated corresponding with corrugated working face, and the lateral side baffle upper width b is less than lower width a.The utility model increases a dribbling surface side side guard compared to traditional corrugated plating, grinds interior grinding dead zone and substantially reduces, as cylinder rotates, abrasive body can be taken to higher position and left again, grinding efficiency improves；Increased lateral side baffle can also play the role of backgauge, make extended residence time of the material in mill, and the fineness for grinding cement out is thinner.

Description

A kind of rib corrugated liner

Technical field

The utility model relates to mechanical seal fields, more particularly to a kind of rib corrugated liner.

Background technique

Cement mill is the cylinder that a both ends have support device, built-in material abrasive body (steel ball) and ground (such as lime stone), total charge weight are the 25 ~ 45% of cylinder dischargeable capacity.Cylinder is turned round around horizontal central axis, and cylinder is intracorporal Abrasive body and material are promoted by shell liner to certain height under the action of centrifugal force and frictional force, are then detached from cylinder waterfall It rushes down or leaves, the movement in cylinder of Matter Transfer is by the continuous Ground shock waves of abrasive body, rod jam pressure and abrasive action and by powder It is broken into the product for certain particle size requirement.Material enters from the hollow shaft of cylinder one end, and the product after being milled is another through cylinder Hold hollow shaft discharge.

Key wear component liner plate is the protection board of cylinder and inlet and outlet material end cap in cement mill motion process, bears to grind The impact and grinding of mill body and material.With the enlargement of cement mill, traditional cement mill corrugated liner does not adapt to The requirement of modern large-sized grinder is primarily present following defect: 1, grinding dead zone is larger in mill, and grinding efficiency decline influences grinding machine Yield；2, flow velocity is fast in grinding, and grinds cement fineness out and runs slightly, influences cement quality.

Utility model content

In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of rib corrugated liner.

The technical solution adopted in the utility model is: a kind of rib corrugated liner, the circular arc and cement of cross section lower end The circular arc of grinding mill barrel inner tube wall is consistent, including integrally formed corrugated working face and lateral side baffle；The corrugated work Make Middle face equipped with fixation hole, the lateral side baffle side is corrugated corresponding with corrugated working face, the lateral side baffle Upper width b is less than lower width a.

Further, the corrugated working face there are three or five ripples.

Further, the lateral side baffle upper width b is 3mm smaller than lower width a.

The beneficial effects of the utility model are: increasing a dribbling surface side side guard compared to traditional corrugated plating, grind Interior grinding dead zone substantially reduces, and as cylinder rotates, abrasive body can be taken to higher position and left again, and grinding efficiency improves； Increased lateral side baffle can also play the role of backgauge, make extended residence time of the material in mill, grind the fineness of cement out It is thinner.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the side view of the utility model.

Liner plate connected enlarged view when Fig. 3 is the side view of cement mill cylinder.

Specific embodiment

It is further to the utility model with reference to the accompanying drawing in order to be more clearly understood that the technical solution of the utility model Explanation.

Such as Fig. 1, a kind of rib corrugated liner shown in 2,3, the circular arc 4 and cement mill cylinder inner cylinder of cross section lower end The circular arc of wall 5 is consistent, including integrally formed corrugated working face 1 and lateral side baffle 2；1 middle part of corrugated working face Equipped with fixation hole 3,2 side of lateral side baffle is corrugated corresponding with corrugated working face 1,2 top of lateral side baffle Width b is less than lower width a.

In this preferred embodiment, there are three the corrugated working faces 1 or five ripples.

In this preferred embodiment, the 2 upper width b of lateral side baffle is 3mm smaller than lower width a.

Working principle: the liner plate is laid in barrel by fixation hole 3 according to fixation as shown in Figure 3, cement grinding mill is worked as When machine drum body rotates, the intracorporal abrasive body of cylinder and material are promoted by shell liner to certain under the action of centrifugal force and frictional force Height, then be detached from cylinder waterfall rush down or leave, moving in cylinder for Matter Transfer is rolled by the continuous Ground shock waves of abrasive body, rod Squeeze and abrasive action and be crushed into the product of certain particle size requirement.Material enters from the hollow shaft of cylinder one end, and grinds Product after powder is discharged through cylinder other end hollow shaft.

The utility model structure is simple, easy to operate, compared to traditional corrugated plating, increases a dribbling surface side side bumper Plate 2 grinds interior grinding dead zone and substantially reduces, as cylinder rotates, abrasive body can be taken to higher position and left again, grinding efficiency It improves；Increased lateral side baffle 2 can also play the role of backgauge, make extended residence time of the material in mill, so that The fineness for grinding cement out is thinner.

The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
