The utility model discloses increased high chromium composite metal hemisphere, welt surface be the metal hemisphere and the compound plane of muscle immediately promptly, has increased the absorbent area of contact of metal magnetic nature, and whole thickness is corresponding reduction 20mm also to reduce the overall weight of welt, increase the inner space of ball mill.
Description
Technical field
The utility model relates to ball mill technical field, more particularly, and particularly a kind of long-life height chromium composite metal magnetic liner plate.
Background technology
Ball grinding machine lining board is the key core parts in ball mill, and its life-span decides interim life-span and the mineral products amount of whole ball mill.
Fig. 1 is the structure chart of protocorm lining board of grinder, comprises metal coating shell 1 ＇, permanent magnet 2 ＇, groove 3 ＇, stud 4 ＇, and this liner plate bag surface adopts single stud structure; in use, because the contact area of metal magnetic absorption is little, want to reach certain adsorptive value; namely need to increase thickness; it uses high manganese steel lining plate simultaneously, and its life-span is short, wears no resistance; volume is large; operating rate is low, and ball mill internal volume is little, and treating capacity is very limited.For this reason, the long-life height chromium composite metal magnetic liner plate designing a kind of improvement is necessary.
Utility model content
The purpose of this utility model is to provide the high chromium composite metal magnetic liner plate that a kind of wearability is good, lightweight, the volume little life-span is long.
In order to solve problem set forth above; the technical solution adopted in the utility model is: a kind of long-life height chromium composite metal magnetic liner plate; comprise metal coating shell and permanent magnet; the upper end of described metal coating shell is provided with some grooves; described permanent magnet is located at the lower end of metal coating shell; and the corresponding permanent magnet of each groove, have stud between adjacent groove, each bottom portion of groove is equipped with the high chromic composite metal hemisphere raised up.
According to a preferred embodiment of the present utility model: described metal coating shell adopts nonmagnetic steel material.
Compared with prior art, the beneficial effects of the utility model are: the utility model adds high chromic composite metal hemisphere, namely backing surface is the composite plane of metal hemisphere and stud, add the contact area of metal magnetic absorption, integral thickness also reduces 20mm accordingly, thus reduce the overall weight of liner plate, increase the inner space of ball mill.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 2 a, 2b and 2c; the utility model provides a kind of long-life height chromium composite metal magnetic liner plate; comprise metal coating shell 1 and permanent magnet 2; the upper end of described metal coating shell 1 is provided with some grooves 3; described permanent magnet 2 is located at the lower end of metal coating shell 1, and the corresponding permanent magnet 2 of each groove 3, between adjacent groove 3, there is stud 4; be equipped with the high chromic composite metal hemisphere 5 raised up bottom each groove 3, optimize the wear-resisting knot performance of liner plate working face.
Described metal coating shell 1 adopts special nonmagnetic steel material; material improves further the content of elemental chromium; improve the content of carbon and the content of chromium in steel; nonmagnetic steel selection is focused on attention and is had wear-resisting, acidproof, alkaline-resisting, corrosion-resistant, the elastomeric material such as magnetic permeability is strong, without hindrance magnetic, and the Main Ingredients and Appearance of material is as following table 1:
Table 1
| Main component | C | Si | Mn | Cr |
| Occupy % | 1.1-1.3 | 0.6-1.0 | 12-14 | 2-3 |
Described permanent magnet 2 adopts and adds the strong magnetic materials such as neodymium, iron, boron to change the change of magnetic field structure and magnetic field force, and liner plate is firmly adsorbed on containment vessel surface under the action of a magnetic force.
Described high chromic composite metal hemisphere 5 adopts high-chromium material, and the Main Ingredients and Appearance of material is as following table 2:
Table 2
| Main component | C | Si | Mn | Cr |
| Occupy % | 1.5-2.0 | 0.6-1.0 | 0.6-1.0 | 15-18 |
In use, magnetic circuit form forms small-closed-loop by ball mill barrel, magnetic liner plate, protective layer (broken ball section, magnetic material) three to the utility model.
After have employed scheme of the present utility model, entirety has the following advantages:
1, because liner plate working face adopts high chromic composite metal hemisphere 5, change by the single stud plane of backing surface the composite plane that hemisphere and stud combine into, improve the contact area of metal magnetic absorption, improve wearability.
2, improve the carbon of steel and the content of these two kinds of elements of chromium in metal coating shell material, the hardness of its liner plate, anti-wear performance is further enhanced, and has again certain toughness.
3, because permanent magnet magnetic force increases, fundamentally decrease the thickness of magnetic liner plate, the overall weight of magnetic liner plate is reduced further, increases ball grinder interior volume space.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
