Abstract
The utility model belongs to the technical field of machinery, and relates to a roller sleeve, in particular to a roller sleeve on a vertical mill. The roller sleeve solves the problems of unreasonable structural design, insufficient strength and the like. The roller sleeve comprises a body, and is characterized in that the body is provided with a central hole, a stepped hole is arranged in the central hole, and the outer surface of the body is further provided with a boss convenient for installation. The roller sleeve has the advantages that excellent connection of the body can be realized by the aid of the central hole arranged on the body, and a roller in the roller sleeve can be well protected from damage.
Description
Technical field
The utility model relates to field of mechanical technique, relates to a kind of roller shell, especially relates to a kind of vertical mill roller shell.
Background technology
Grinding machine is different according to milling medium and grinding material, can be divided into ball mill, rod mill, tube mill, and autogenous tumbling mill revolves mortar formula roller mill etc.Ceramic industry is generally adopted intermittent ball mill in producing; Adopt wet production, its abrasive action can be divided into two parts, the one, between the abrasive body and abrasive body and simplified between abrasive action; The 2nd, the percussion when abrasive body falls will be started with from this two aspect in order to improve grinding efficiency." the how broken few mill " technology and the technology of metallic ore are topics of having carried a lot of years, reduce the mill feed size of ball mill, before ball mill, increase by one section pre-grinding or ultra-fine broken technology, are the energy-saving and cost-reducing important technology innovations of bargh.The research of grinding machine comminution technology is one of emphasis in the Mineral Processing Engineering technology.Comminution technology is to utilize energy that ore is pushed, impacts and grinds through grinding machine, makes valuable mineral monomer cleavage in the ore, is beneficial to the process that the next stage sorts.
One of part that the roller shell grinding machine is indispensable, it is to be socketed in the part that plays a protective role above the roller, and roller shell exists the some shortcomings part at present, and unreasonable such as the existing structure design, problems such as insufficient strength still exist.
The utility model content
The purpose of the utility model is to the problems referred to above, provides a kind of intensity high, rational in infrastructure, the roller shell of long service life.
For achieving the above object, the utility model has adopted following technical proposal: the roller shell on this vertical mill comprises body; It is characterized in that; Shown body is provided with centre bore, is provided with shoulder hole in the shown centre bore, and this external surface look is convenient to the boss installed in addition.
Roller shell on above-mentioned vertical mill is provided with rounding in the described shoulder hole.
Roller shell on above-mentioned vertical mill, described body adopts the stainless steel manufacturing.
Compared with prior art, the advantage of the utility model is: body is provided with centre bore, can realize that through centre bore body well connects; Can protect running roller wherein, avoid its damage.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, body 1, centre bore 11, shoulder hole 12, boss 2.
The specific embodiment
As shown in Figure 1, the roller shell on a kind of vertical mill comprises body 1, and shown body 1 is provided with centre bore 11, and body is provided with centre bore 11, can realize that through centre bore 11 body 1 well connects; Can protect running roller wherein, avoid its damage.Be provided with shoulder hole 12 in the shown centre bore 11; Body 1 appearance complexion is convenient to the boss 2 installed in addition, can realize good location through boss 2, and boss 2 tops is provided with chamfering; Can reduce other part of its scratch; Be provided with rounding in the described shoulder hole 12, described body 1 adopts the stainless steel manufacturing, has prolonged the life-span of using through the stainless steel manufacturing.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
