Abstract

The invention discloses a milling roller for a roller mill. The milling roller comprises a roller shaft, wherein a roller sleeve is fixedly coupled with the upper end of the roller shaft, the cross section of the roller shaft takes the shape of a reverse frustum, the appearance of the roller shaft looks like the flame of a torch, the roller sleeve is made of a wearable medium, the lower end of the roller shaft is sleeved with a bearing sleeve with a hinge lug, a bearing is mounted between the bearing sleeve and the roller shaft, and the appearance of the roller shaft looks like a handle of the torch. The milling roller is capable of maximizing the wearing amount in a limited space, reducing difficulties caused by the machining of the high hardness wear material, bearing frequent vibration and larger axial force; the milling roller is further flexible in operation, little in operation resistance, long in service life, convenient to exchange, and easy to maintain; by use of the milling roller, the milling efficiency of the mill can be improved, and the noise, the energy consumption and the operation cost can be reduced.

Description

A kind of roller mill grinding roller

Technical field

The present invention relates to a kind of grinding device member, especially relate 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.

Summary of the invention

Invention 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.

Technical scheme of the present invention is: a kind of 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 present invention's grinding roller, 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 one embodiment of the invention.

The specific embodiment

Below in conjunction with drawings and Examples the present invention 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 present invention's torch shape grinding roller, 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. a 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.
