Abstract

The utility model provides a combined roll ring for a roll crusher. The combined roll ring comprises a roll ring body (1), roll tooth sets (2), key ways (3) and a wear-resistant layer (4), and is characterized in that: the roll tooth sets (2) are formed by combining two large roll teeth (2.1) and a small roll tooth (2.2) respectively and are uniformly distributed on the roll ring body; the large and small roll teeth are non-uniformly arranged and the wear-resistant layer (4) is overlaid or embedded on the roll teeth; and the number of the key ways formed on the inner wall of a roll tooth body is relatively prime with the number of the roll tooth sets. The outer wall of the roll ring body (1) has a stepped cylindrical structure; a plurality of V-shaped key ways (3) are uniformly distributed on the inner wall of the roll ring body (1); the shape of the roll ring structure is formed by casting at one time; and the wear resistance of the wear-resistant layer (4) overlaid or embedded on the edges of the roll teeth is higher than that of the roll ring body and the roll teeth. The roll ring has a firm structure, and excellent wear resistance and impact resistance and is low in processing cost; the crushing performance of the roll crusher can be improved; and the service life of the roll crusher can be prolonged.

Description

The composite roll circle that is used for kibbler roll

Affiliated technical field

The utility model relates to a kind of composite roll circle that is used for kibbler roll, and kibbler roll is used for broken clinker, so that grog reaches the granularity requirements of regulation, is convenient to the further pulverizing of grog.

Background technology

The operating rate of kibbler roll probably is 4rpm, and hammer is broken to utilize tup impact grinding material so its smashing principle is different from, but utilizes the roller tooth on the roller circle that material is carried out attrition crushing.In whole shattering process, the roller circle directly contacts with material, and the quality of its performance has determined the quality of crushing performance.High cylindrical-shaped structures such as the many employings of roller circle body outer wall of kibbler roll use at present, roller circle body inwall keyway is that traditional keyway connects, and the roller tooth adopts even the distribution mostly.Though these roller circles also can be accomplished the material crushing operation, run into bulk materials and just can cause material to snap in the tooth, cause crushing efficiency to descend.In addition, increase the weight of and roller tooth discontinuity owing to the slip teeth surface wear of bulk materials on the flank of tooth in the shattering process, thereby the service life of having reduced the roller circle.

Summary of the invention

The purpose of the utility model is, a kind of firm in structure, processing cost is low, use is reliable, maintenance workload is little composite roll circle is provided, and this roller circle can improve kibbler roll crushing performance and service life.

The composite roll circle that is used for kibbler roll that the utility model provided; It comprises roller circle body (1), roller tooth group (2), keyway (3), wearing layer (4) part; It is characterized in that: roller tooth group (2) combines and is uniformly distributed on the roller circle body by two big roller teeth (2.1) and a pony roll tooth (2.2); Two kinds of roller teeth of size adopt non-homogeneous layout and built-up welding or inlay wearing layer (4) on it, and roller denticle number that inwall splines and roller tooth group number be prime number each other; Roller circle body (1) outer wall adopts the ladder cylindrical-shaped structure, roller circle body (1) the inwall plurality of V-shaped keyway (3) that evenly distributes; Roller coil structures type shape is through the casting one-shot forming, roller tip surface limit built-up welding or inlay wearing layer (4), and the wearability of wearing layer (4) is higher than roller circle body and roller tooth.

The beneficial effect of the utility model is: roller tooth group number and keyway number are mutual prime rwmber; The long strip type that the roller shell (5) that makes some roller circles combine structurally can avoid the forming perforation groove that gets stuck; On width, interrupted the periodicity rhythm and pace of moving things of gear hobbing; Avoided the roller shell periodically generation of apical tooth phenomenon in the period run process on the two broken rollers; And then having improved the uniformity of the crushing efficiency and the discharging-material size of disintegrating machine, the material ratio that broken back granularity is in the scope of design has brought up to 93% by about 76%; Roller circle body outer wall adopts the ladder cylindrical-shaped structure, and it can adapt to the material of different size shape with the formed ladder height difference of roller tooth, and then combines large and small roller tooth to realize material selective crushing, has optimized roller tooth utilization rate effectively; The roller circle body inwall V-type keyway that evenly distributes can make roller circle inwall stressed evenly and optimized the keyway force-bearing situation; The roller circle body adopts the casting one-shot forming, and processing cost is low, roller tip surface limit built-up welding or inlay the anti-abrasive resistance that wearing layer can be strengthened roller tooth crown position, thus roller circle service life has been brought up to more than 15000 hours from 7000 hours of routine.

The specific embodiment

Accompanying drawing 3 is one of embodiment of this utility model.In this embodiment, roller circle and unshowned in the accompanying drawings kibbler roll roll shaft adopt the V-type keyway to be connected to form roller shell, thereby the periodic running relatively of the roller shell on the two broken rollers realizes broken function.The accompanying drawing 3 described composite roll circles that are used for kibbler roll; Comprise roller circle body and the roller tooth that is positioned at roller circle body outer wall; It is 15 that the roller tooth adopts non-homogeneous layout quantity, and wherein 10 in big roller tooth, 5 in pony roll tooth are formed 5 roller tooth groups altogether, roller tip surface limit built-up welding or inlay wearing layer.Consider in the roller circle design material is nipped in the process of broken groove and broken material that roller tooth crown stress is bigger, and booster action is played at other positions of the flank of tooth, so the wearing and tearing of roller tooth crown are the most obvious.In order to improve material interlock ability, strengthen the antiwear property at roller tooth crown position, thus the service life of improving the roller circle; So in the process of roller circle; In the position that the position preprocessing of roller tooth crown goes out the wearing layer built-up welding or inlays, come the final roller tooth moulding of accomplishing through built-up welding or damascene process, design through reasonable technology; Can make roller tooth crown hardness reach 60～65HRC; When guaranteeing result of use, reduce processing cost and difficulty more, reduced maintenance cost, greatly improved production efficiency and economic results in society.
