Abstract
The utility model discloses a mill roller and a mill ring of a Raymond mill, which comprise an inner ring base layer and an outer ring grinding layer of the mill roller, and an outer ring base layer and an inner ring grinding layer of the mill ring. The outer ring grinding layer of the mill roller and the inner ring grinding layer of the mill ring are high-chromium material layers which are high-chromium welding wire surfacing layers with thickness ranging from 10mm to 30mm. the inner ring base layer of the mill roller and the outer ring base layer of the mill ring are 20# steel or 20# silicon-manganese material layers. The mill roller and the mill ring has higher grinding hardness, greatly increases service life by three to five times, reduces replacement times, effectively saves maintenance time and increases production efficiency.
Description
(1) technical field:
The utility model relates to abrasive dust equipment machine parts, is a kind of grinding roller and bull ring of Raymond machine specifically.
(2) background technology:
Abrasive dust equipment is typical case's representative with the Raymond machine, its operation principle centrifugal force that to be the horizontal grinding roller of dependence produce in the revolution running and on bull ring rotation roll material (metal or nonmetallic ore) ground, because requirement to hardness, grinding roller and bull ring are handled through surface heat with the ZGMn13 high manganese steel material usually and are made, and make its working face have certain thickness wear-resisting milling (hard) layer.Under the long-term condition of work, the heat treatment of grinding roller and bull ring (hard) layer wearing and tearing gradually of milling, hardness reduces, and does not reach the requirement of milling to material (metal or nonmetallic ore), has only the grinding roller of replacing and bull ring for dealing with problems.Change grinding roller and bull ring continually,, can cause the delay of working time and the increase of financial cost particularly for large-scale Raymond machine.
(3) utility model content:
At the problem that traditional Raymond machine grinding roller and bull ring exist, the purpose of this utility model is to disclose a kind of prolongation grinding roller and bull ring service life, reduces the grinding roller and the bull ring of maintain and replace number of times.
Can realize the grinding roller and the bull ring of the Raymond machine of above-mentioned purpose, comprise the interior cyclic group bed of material of grinding roller and the outer shroud outer shroud binder layer of layer, bull ring and the interior ring layer of milling of milling, the outer shroud of different the is described grinding roller interior ring of layer and the bull ring layer of milling of milling is the high-chromium material layer, the high-chromium material layer has very high hardness, can increase substantially the rub proofness of grinding roller and bull ring.
Described high-chromium material layer be with built-up welding machine special equipment with high chromium welding wire built-up welding on the binder layer of grinding roller and bull ring.
According to each specification grinding roller and the bull ring and the processing object thereof of different Raymond machines, the built-up welding thickness of described high chromium welding wire built-up welding layer is between 10mm～30mm.
The interior cyclic group bed of material of described grinding roller and the outer shroud binder layer of bull ring can be selected low-cost No. 20 steel or the violent manufacture of materials of 20 silicon for use.
Advantage of the present utility model:
1, the layer of milling of the grinding roller of the utility model Raymond machine and bull ring adopts high chromium welding wire built-up welding layer, heat treated hardness is higher through the surface than traditional Z GMn13 high manganese steel material, increased substantially the service life (3～5 times) of grinding roller and bull ring, reduce the replacing number of times of grinding roller and bull ring, effectively save maintenance time, enhance productivity.
2, the utility model is the high chromium floor of built-up welding on the grinding roller of No. 20 steel or the violent steel of 20 silicon and bull ring binder layer, and overall cost is not that very high, more traditional grinding roller and bull ring has higher cost performance.
3, the utility model is fit to above metallic ore or the nonmetallic ore of 4 grades of hardness of processing Mohs.
(4) description of drawings:
Fig. 1 is the structural representation of grinding roller in a kind of embodiment of the utility model.
Fig. 2 is the structural representation of bull ring in a kind of embodiment of the utility model.
Figure number sign: 1, the interior cyclic group bed of material; 2, the outer shroud layer of milling; 3, outer shroud binder layer; 4, the interior ring layer of milling.
(5) specific embodiment:
In embodiment shown in Figure 1, No. 20 steel of the interior cyclic group bed of material 1 usefulness or the violent steel of 20 silicon of the utility model grinding roller process, the outer shroud of grinding roller is milled layer 2 for the high-chromium material layer, be with the interior cyclic group bed of material 1 of high chromium welding wire built-up welding with special-purpose built-up welding machine equipment in grinding roller, according to the specification and the purposes of grinding roller, its outer shroud mill the layer 2 (high-chromium material layers) built-up welding thickness between 10mm～30mm.
In embodiment shown in Figure 2, No. 20 steel of outer shroud binder layer 3 usefulness or the violent steel of 20 silicon of the utility model bull ring process, the interior ring of bull ring is milled layer 4 for the high-chromium material layer, be with the outer shroud binder layer 3 of high chromium welding wire built-up welding with special-purpose built-up welding machine equipment in bull ring, according to the specification and the purposes of bull ring, the built-up welding thickness that encircles the layer 4 (high-chromium material layers) of milling in it is between 10mm～30mm.
Claims (4)
