Abstract

The utility model discloses a roll body structure of shaft shoulder type high-pressure roll grinder. A shaft shoulder is arranged on the end of a roll body, and a crushing chamber is composed of the shaft shoulder and the roll body. Because the utility model disuses baffle plates which are arranged on both ends of the two roll bodies, the crushing chamber is formed by the shaft shoulder of the roll body, therefore a sliding friction problem of materials on both of the two ends does not exist, 'the edge effect' can be avoided, and the service life can be extended. Additionally, when a roll gap is enlarged and needs to be readjusted after the roll bodies are worn, only need to regulate the height of the shaft shoulder.

Description

Shaft shoulder formula high-pressure roller mill roll body structure

Technical field

The application relates to the high-pressure roller mill that industries such as mine, building materials are used, and relates in particular to the roll body of high-pressure roller mill.

Technical background

The high-pressure roller mill roll body all is cylindric at present, forms crusher chamber by the side shield at two roll bodies and roll body two ends.During broken material, because roll gap pressure is very high, the material in the crusher chamber certainly will be along roller axle to overflowing to both sides, for anti-spilled side shield will be along roller axle to applying pressure; The method that holds out against generally use leading screw (referring to " the novel extruding grinding technology of cement industry ", Huang Youfeng etc. write, and Chinese building material industry publishing house publishes, in March, 1996 front page.)。Since material under pressure with the side shield sliding friction, the side shield wearing and tearing are exceedingly fast, often promptly scrapped in 7-10 days, the wearing and tearing of side shield have aggravated the generation of " edge effect ", be that limit portion marker size is bigger, influenced the processing parameter matching of equipment such as high-pressure roller mill and relevant grinding machine, impacted for normal stable production.The existence of sliding friction causes roller end outer rim long term wear, has also increased useless power consumption.Irregular wearing and tearing shape is returned the adjustment of roller end side shield and is brought difficulty, and when serious, side shield does not have the backgauge effect at all.

Summary of the invention

The application's purpose is to overcome the deficiencies in the prior art, and the high-pressure roller mill roll body structure of a kind of nothing " edge effect " is provided.

The application's technical scheme is at the roll body end design shaft shoulder, constitutes crusher chamber by the shaft shoulder and roll body.

The application's technique effect is: removed the baffle plate at two roll body two ends from, formed crusher chamber by the shaft shoulder of roll body, therefore do not had the sliding friction problem of material at two ends, avoided " edge effect ".After the roll body wearing and tearing, roll gap becomes in the time of need readjusting roll gap greatly in addition, as long as shaft shoulder height is repaired.

Description of drawings

Fig. 1 is the schematic diagram that two roll body two ends respectively have the shaft shoulder; Fig. 2 is that the shaft shoulder, B roller are arranged is the schematic diagram of smooth roll at A roller two ends; Fig. 3 is that an end of A, B two roll bodies respectively has the schematic diagram of the shaft shoulder.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, each figure has respectively represented a kind of embodiment.Among Fig. 1 as A, when B roll body two ends respectively have the shaft shoulder 1, two roll shafts shoulder 1 connects and roll surface forms crusher chamber 2; Among Fig. 2 when A roll body two ends have the shaft shoulder 1, with the corresponding formation crusher chamber 2 of the roll surface of B smooth roll body; Among Fig. 3 when A and B roll body one end all have the shaft shoulder 1, the corresponding formation crusher chamber 2 of the shaft shoulder 1 of roll body with the roll surface of two roll bodies.Are advisable with 2-3mm in the gap in the above-described structure between two roll shafts shoulder or the gap of the shaft shoulder and smooth roll face.Form shown in Figure 2 also can A, B be exchanged.

Claims

1. shaft shoulder formula high-pressure roller mill roll body structure, it comprises A roll body and B roll body, it is characterized in that forming crusher chamber by the shaft shoulder and the roll surface of roll body end.

2. roll body structure as claimed in claim 1 is characterized in that A roll body one end has the shaft shoulder, and the B roll body other end has the shaft shoulder.

3. roll body structure as claimed in claim 1 is characterized in that A roll body and B roll body two ends respectively have the shaft shoulder.

4. roll body structure as claimed in claim 1 is characterized in that A roll body two ends have the shaft shoulder, and the B roll body is a smooth roll.
