Abstract
A pendulum flour mill grinding roll of the utility model belongs to the field of grinding machinery. The utility model provides a pendulum flour mill grinding roll composed of two parts in order to solve the problem of the unnecessary waste produced by the grinding roll of the existing food grinder. The outer liner and the inner liner of the utility model are connected through a bolt. The other end of the bolt is fixedly connected through a cap nut. The bolt is in an 'L'-shaped and is fastened in the elevator groove on the outer liner. The structure of the utility model is simple. The installation and the using are convenient. Because the utility model adopts two parts: an inner liner and an outer liner, if the inner liner is worn, the inner liner can be changed and if the outer liner is worn, the outer liner can be changed. The availability ratio of metal can be enhanced by more than 90%. The utility model has better social and economic benefit.
Description
Technical field:
The utility model belongs to the abrasive dust mechanical field.
Background technology:
Pendulum type ring roll pulverizer is high-power station's processing coal dust, the conventional machinery of nonmetallic ore processing ore powder, and the present use amount of China is greatly about more than ten thousand.Grinding roller is the main easily worn part of flour mill, and the grinding roller major part of existing flour mill is one-shot forming, when grinding roller is scrapped, has the metal about half not to be utilized, and virtually for enterprise has increased cost, also causes very big waste.
Technology contents:
In order to address the above problem, the utility model provides a kind of dimeric pendulum type ring roll pulverizer grinding roller.
Overcoat of the present utility model is connected by bolt with interior cover, and the bolt other end is fixedly connected by nut.
Bolt becomes " L " type, is stuck in the outer draw-in groove that puts.
The utility model is simple in structure, and is easy to install, owing to adopt inside and outside cover two parts, as long as interior cover wearing and tearing are overlapped in changing, the overcoat wearing and tearing are changed overcoat and got final product, and improve using rate of metal and reach more than 90%, have good social and economic benefit.
Description of drawings:
Accompanying drawing is the utility model structure cutaway view.
The specific embodiment:
The utility model is divided into overcoat 1 and interior cover 2 two parts, overcoat 1 and 2 correspondences of interior cover the screw passage arranged, by overcoat 1 and interior cover 2 are fixed together, bolt 3 other ends are fixedly connected by nut by screw for bolt 3.The quantity of bolt and screw passage can be decided according to fixation degree, but is one at least.
In order to reach better fixing, bolt 3 is made into " L " type, and bolt 3 is stuck in the draw-in groove on the overcoat 1.
