Abstract
The utility model provides a semi-autogenous mill grid plate which comprises an outer ring grid plate, a center rubber lining plate and an inner ring lining plate that is positioned between the outer ring grid plate and the center rubber lining plate, and is characterized in that the inner ring lining plate is provided with through holes. The design of changing the inner ring lining plate into a grid plate increases the aperture ratio of the semi-autogenous mill grid plate by 8.56%, leads the inner lining plates incapable of participating in the screening of ores originally to screen the ores also, improves the working efficiency of a semi-autogenous mill, and increases the ore discharge amount of the semi-autogenous mill. Simultaneously, the hour treatment capacity of the semi-autogenous mill is obviously increased from designed 537.2t/h to 610.7t/h, the time is saved, and the efficiency is improved. The weight of a single lining plate is reduced from 879kg to 584kg, and the production cost and raw materials are saved. The semi-autogenous mill grid plate is an ideal semi-autogenous mill grid plate in deed.
Description
Technical field
The utility model relates to a kind of grate, and particularly a kind of semi-autogenous mill grate belongs to the benficiation machinery technical field.
Technical background
In the ore dressing plant, semi-autogenous mill is very important a kind of benficiation machinery, the semi-autogenous mill exhaust end of prior art is by the grate of outer ring, the rubber lining at center, inner ring liner plate between outer ring grate and center rubber lining constitutes, because what the inner ring liner plate adopted is the blind plate design, so in ore dressing, the ore that meets required particle diameter can only be selected by the grate of outer ring.Ore quantity by grate is reduced, promptly can not once just all select qualified ore, can only repeatedly handle, not only make hour disposal ability of semi-autogenous mill not satisfy the demand of technological process, also can increase the ore dressing time, influence operating efficiency, the development that final restriction is produced.Therefore be necessary prior art is improved.
Summary of the invention
Low for solving existing semi-autogenous mill grate percent opening, ore dressing speed is slow, even will repeatedly screen just and can finish ore dressing, thereby causes ore dressing work inefficiency, time-consuming problem such as take a lot of work, and the utility model provides a kind of semi-autogenous mill grate.
The utility model is finished by following technical proposal: a kind of semi-autogenous mill grate, comprise the outer ring grate, and center rubber lining and therebetween inner ring liner plate is characterized in that the inner ring liner plate is provided with through hole, so that ore passes through hole and selects.
Hole on the described inner ring liner plate has a plurality of, and its percent opening is 11.78%, to increase the ore percent of pass.
Hole shape on the described inner ring liner plate is made as a kind of in circular port, rectangular opening, the mounting hole or is made as several combination in them.
Described inner ring liner plate is combined by the polylith fanning strip, through hole evenly or non-uniform Distribution on fanning strip, so that make interior lining panel also can carry out ore screening.
The utlity model has following advantage and effect: adopt such scheme, change the design of grate into by the inner ring liner plate, the percent opening of semi-autogenous mill grate has improved 8.56%, make the interior lining panel that can not participate in ore screening originally also can carry out ore screening, greatly improve the operating efficiency of semi-autogenous mill, increased the ore discharge amount of semi-autogenous mill.Simultaneously, the autogenous tumbling mill throughput per hour is significantly improved, and brings up to 610.7t/h from the 537.2t/h that designs, and the time of having saved has been improved efficient.Monolithic liner plate weight is reduced to 584kg by 879kg, and a cover grate is 16 blocks of liner plates, alleviates 4.9 tons altogether, has saved cost of manufacture and raw material.Be a desirable semi-autogenous mill grate in fact.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial enlarged drawing of interior lining panel among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.
The semi-autogenous mill grate that the utility model provides, comprise outer ring grate 1, center rubber lining 2 and therebetween inner ring liner plate 3, outer ring grate 1 and inner ring liner plate 3 interconnect circular by fanning strip in twos, on inner ring liner plate 3, be provided with through hole 4, so that ore passes through hole and selects, wherein, hole on the inner ring liner plate 3 has a plurality of, hole shape is made as circular port and mounting hole, and percent opening is 11.78%, and through hole 4 non-uniform Distribution are on fanning strip, to increase the ore percent of pass, carry out ore screening simultaneously.
Claims (4)
1. a semi-autogenous mill grate comprises the outer ring grate, and center rubber lining and therebetween inner ring liner plate is characterized in that the inner ring liner plate is provided with through hole.
2. semi-autogenous mill grate according to claim 1, it is a plurality of to it is characterized in that hole on the described inner ring liner plate has, and its percent opening is 11.78%.
