Abstract

A grinding roller for a roller mill comprises a roller shaft; a roller sleeve is connected fixedly and axially to the upper end of the roller shaft; the section of the roller sleeve is shaped like a reversed frustum, and the external form of the roller sleeve is shaped like the flame of a torch; the roller sleeve is made of wear-resistant mediums; the lower end of the roller shaft is sheathed with a bearing sheath with a hinge lug; a bearing is arranged between the bearing sheath and the roller shaft; and the roller shaft is shaped like the handle of a torch. The grinding roller can increase the wearable amount to the greatest extent within limited space, reduce the difficulty in machining high-hardness wear-resistant materials and bear frequent vibration and large axial force, and has the advantages of flexible operation, small operation resistance, long service life, convenient replacement and simple repair. The grinding roller can improve grinding efficiency and reduce noise, energy consumption and operation cost.

Description

The roller mill grinding roller

Technical field

The utility model relates to a kind of grinding device member, especially relates to a kind of roller mill grinding roller.

Background technology

Grinding roller is a requisite important component in the milling equipment, and whether its structure is reasonable, and whether mounting means science, and the simplicity of mill efficiency and grinding machine service life, maintenance and energy resource consumption height, running noises size etc. are all had a significant impact.

There is unreasonable structure in the grinding roller of existing roll mill pulverizer, and low as the high-abrasive material utilization rate of powder grinding medium, mill efficiency is low, and service life is short, and noise is big, changes drawbacks such as inconvenience.

The utility model content

Utility model provides a kind of mill efficiency that improves at the defective of the grinding roller existence of existing roll mill pulverizer, cuts down the consumption of energy, and long service life is keeped in repair easy roller mill grinding roller.

The technical solution of the utility model is: the roller mill grinding roller, comprise roll shaft, and the upper end of the described roll shaft roller shell that fixedly is coupling, described roller shell cross section is inversed taper platform shape, is similar to the flame of torch outward, and roller shell is a wear-resistant medium; The bearing holder (housing, cover) of the lower end socket one door assembly with hinge and glass in right hand and left ear of roll shaft is equipped with bearing between described bearing holder (housing, cover) and the roll shaft; Described roll shaft is similar to the handle of torch outward.

During installation, the hinge lug on the bearing holder (housing, cover) is connected with the rotating disk of roller mill by bearing pin.

The grinding roller of the utility model, but wear extent can in limited space, be increased to greatest extent; The difficulty that minimizing brings the machined of high hardness wear-resisting material; Can bear frequent vibration and larger axis to power, go slick, running resistance is little, long service life, and it is convenient to change, and keep in repair easyly, can improve mill grinding efficiency, reduction noise, energy consumption and operating cost.

Description of drawings

Fig. 1 is the structural representation of the utility model one embodiment.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

With reference to Fig. 1, present embodiment comprises roll shaft 2, the upper end of described roll shaft 2 roller shell 1 that fixedly is coupling, and described roller shell 1 cross section is inversed taper platform shape, is similar to the flame of torch outward, and roller shell 1 is a wear-resistant medium; The bearing holder (housing, cover) 4 of the lower end socket one door assembly with hinge and glass in right hand and left ear 3 of roll shaft 2 is equipped with bearing 5 between described bearing holder (housing, cover) 4 and the roll shaft 2; The handle of described roll shaft 2 outer likeness in form torches.

The torch shape grinding roller of the utility model, but wear extent can in limited space, be increased to greatest extent; The difficulty that minimizing brings the machined of high hardness wear-resisting material; Can bear frequent vibration and larger axis to power, go slick, running resistance is little, long service life, and it is convenient to change, and keeps in repair easyly, can improve mill grinding efficiency, cuts down the consumption of energy and operating cost.

Claims

1. the roller mill grinding roller comprises roll shaft, it is characterized in that, and the upper end of the described roll shaft roller shell that fixedly is coupling, described roller shell cross section is inversed taper platform shape, is similar to the flame of torch outward, and roller shell is a wear-resistant medium; The bearing holder (housing, cover) of the lower end socket one door assembly with hinge and glass in right hand and left ear of roll shaft is equipped with bearing between described bearing holder (housing, cover) and the roll shaft; Described roll shaft is similar to the handle of torch outward.
