Description
Technical field
The utility model is related to chemical machinery technical fields, and in particular to a kind of novel bull ring of grinding machine and grinding roller.
Background technology
Raymond mill is also known as raymond mill, commonly uses milling equipment, is mainly used for barite, calcite, potassium feldspar, cunning
Stone, marble, lime stone, dolomite, fluorite, lime, atlapulgite, activated carbon, bentonite, kaolin, cement, rock phosphate in powder,
Gypsum, glass, green stone, petroleum coke etc..It is widely used in mine, cement plant, the milling equipment in chemical plant is nonmetallic mineral depth
One of important equipment of processing.Because Raymond mill performance is stable, adaptable, cost-effective, from introduce China over more than 20 years, by
Popularization and application is in the processing of nonmetallic mineral.
Its main operational principle is that large-block material, will by elevator after jaw crusher is crushed to required granularity
Material is sent to storage bin hopper, then is continually fed into mainframe grinding chamber and is ground through oscillating feeder equal and quantitative, the powder after grinding
Material is taken away by fan airflow.Grinding mainly rolls bull ring under the action of the centrifugal force by grinding roller, and scooping up material by perching knife is sent to mill
Among roller and bull ring, material is broken into powder under the action of grinding pressure.
Traditional bull ring and roller surface is plane, and milling area is small, and effect is poor, and efficiency is low.
Utility model content
A kind of novel bull ring of grinding machine of the utility model offer and grinding roller.
The specific technical solution of the utility model is：Including bull ring, grinding roller, groove, sawtooth, convex tooth, axis hole；The bull ring
Being one has honest and kind annulus, and in bull ring inner ring face middle position, setting is fluted, and groove is in the bull ring cross section
A dovetail groove；The grinding roller is a cylinder, is made of upper and lower two discs and outer surface, in grinding roller outer surface lean-with
It installs and is equipped with convex tooth, the convex tooth is trapezoidal protrusion；The bull ring inner ring groove both sides are provided with sawtooth, outside the grinding roller
The surface both sides Tu Ya are provided with sawtooth；It is axially provided with axis hole in grinding roller.
It is further preferred that the bottom edge of the groove and the angle of two waist edges are 125 degree ~ 90 degree.
It is further preferred that the bottom edge of the convex tooth and the angle of two waist edges are 125 degree ~ 90 degree.
It is further preferred that the bull ring and grinding roller are made of wear-resistant materials.
The utility model has the beneficial effects that：Compared with traditional bull ring and grinding roller, bull ring provided by the utility model and
The fluted and raised tooth of grinding roller band increases the area of grinding, while groove design can allow material to be easier, the longer time stops
Protrusion on abradant surface, grinding roller can crush effectively, grinding material, and more preferably, multiple small-sized sawtooth can effectively be ground grinding effect
Smaller material block and particle.

Specific implementation mode
The technical issues of in order to keep the utility model solved, technical solution are more clearly understood, below in conjunction with attached drawing and
The utility model is further described in embodiment.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
As shown in Figures 1 to 4, a kind of novel bull ring of grinding machine and grinding roller, including it is bull ring 1, grinding roller 2, groove 3, sawtooth 4, convex
Tooth 5, axis hole 6；The bull ring 1, which is one, honest and kind annulus, and in 1 inner ring face middle position of the bull ring, setting fluted 3, recessed
Slot 3 is a dovetail groove in 1 cross section of the bull ring；The grinding roller 2 is a cylinder, by upper and lower two discs and outer surface group
At being provided with convex tooth 5 in 2 outer surface middle position of the grinding roller, the convex tooth 5 is trapezoidal protrusion；It is recessed in 1 inner ring of the bull ring
3 both sides of slot are provided with sawtooth 4, and convex 5 both sides of tooth in 2 outer surface of the grinding roller are provided with sawtooth 4；Axially it is provided with axis in grinding roller 2
Hole 6.
The bottom edge of the groove 3 and the angle of two waist edges are 125 degree ~ 90 degree.
The bottom edge of the convex tooth 5 and the angle of two waist edges are 125 degree ~ 90 degree.
The bull ring 1 and grinding roller 2 are made of wear-resistant material, such as high chrome, low-chrome steel, B2 steel, chrome-moly steel.
Compared with traditional bull ring and grinding roller, bull ring and the fluted and raised tooth of grinding roller band increase the area of grinding, together
When groove design material can be allowed to be easier, rest on abradant surface for more time, the protrusion on grinding roller can crush effectively, abrasive material
Material, more preferably, multiple small-sized sawtooth can effectively grind smaller material block and particle to grinding effect.
The utility model is described in detail above by specific and preferred embodiment, but those skilled in the art answer
This understands that the utility model is not limited to embodiment described above, within the spirit and principle of the utility model, is made
Any modification, equivalent replacement etc., should be included within the scope of protection of this utility model.
