CN2614785Y - Honycomb type whole-wave shape non-bolt lining plate for ball mill - Google Patents

Abstract

The utility relates to a ball grinder honeycomb-type full-waveform non-screw spear plate, which comprises a spear plate body (1), a spherical honeycomb structure (2) on the spear plate and a groove (3), and is characterized in that the spear plate is full-waveform face. One end face (B) of the spear plate is a plane, and the other end face is the middle concave to form two small planes (A). A rivet plate (4) is arranged between two spear plates. The ball grinder honeycomb-type full-waveform non-screw spear plate of the utility model is all wave-form on the whole surface of the spear plate, which makes the spear plate have strong ball-keeping ability, and accomplishes an ideal grinding smashing effect. The joint between two spear plates is more compact and reliable. A rivet plate is arranged between two spear plates, which makes the spear plate form strong fastening force when the inner stress changes, and enables the spear plate to operate safely and reliably without pull-off. The spear plate of the utility model has the advantages of long serve life, low production cost, and strong serviceability, or the like.

Description

Ball mill honeycomb fashion all-wave shape non-bolt liner plate

Technical field

The utility model relates to mining machinery, specifically uses ball mill honeycomb fashion all-wave shape non-bolt liner plate.

Background technology

Ball mill is the big machinery main process equipment that industries such as cement, mine, power plant, metallurgy generally adopt; Wherein, apply one deck liner plate protection grinding mill barrel in the ball mill.Ball mill is a kind of high energy consumption, inefficient mechanical crushing, milling apparatus.Owing to have certain defective on the existing ball grinding machine lining board structure, make liner plate shorter relatively service life.Only be used in the metal material consumption on the liner plate, the whole nation reaches more than 300,000 tons every year, and in order to improve the service life of ball grinding machine lining board, my patent formerly (ZL94209924.9) has reduced the abrasion of liner plate metal to a certain extent.The structural shape that full classification advances is in service with empty grinding machine in theory, and liner plate plays " classification " effect really to abrasive body (abrading-ball), i.e. the obvious segmentation of sizes of balls; But fill very thick one deck in actual production process because in the grinding machine and treat comminuting matter, abrasive body is not in the operation of liner plate surface, drops on the material but incline, and material is done to pulverize grind.So its " classification " effect there is not condition to manifest, actual effect is unsatisfactory.

Summary of the invention

The purpose of this utility model provides a kind of better wearability that has, the ball mill honeycomb fashion all-wave shape non-bolt liner plate that service life is higher.

The technical solution of the utility model is: comprise the liner plate body and on sphere honeycomb and groove, it is characterized in that liner plate is full wavy surface, liner plate one end face has the riveting plate for the other end, plane is middle recessed formation two facets between liner plate and the liner plate.

Ball mill honeycomb fashion all-wave shape non-bolt liner plate of the present utility model is a wave mode all on whole liner plate face, makes liner plate have stronger dribbling ability, the grinding-crushing effect of realizing ideal.End at liner plate is middle recessed formation two facets, make it compacter when liner plate is connected with liner plate, reliable, when liner plate is installed on the cylindrical shell of ball mill, between liner plate and liner plate, be provided with the riveting plate, make liner plate when internal stress changes, still can form very strong fastening force, make liner plate safe and reliable to operation, unlikely coming off.Advantages such as liner plate of the present utility model has long service life, production cost is low, and is practical.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a lining plate structure schematic diagram of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is a liner plate mounted configuration schematic diagram of the present utility model;

Fig. 4 is a riveting plate structure schematic diagram of the present utility model.

Among the figure, 1-liner plate body, 2-honeycomb, 3-groove, 4-riveting plate, 5-ball mill barrel.

The specific embodiment

As shown in the figure, ball mill honeycomb fashion all-wave shape non-bolt liner plate of the present utility model by liner plate body 1 and on sphere honeycomb 2 and groove 3 and liner plate be that full wavy surface, liner plate one end face B are that the recessed two facet A that form constituted in the middle of plane, other end were; Riveting plate 4 is arranged between liner plate and the liner plate.Honeycomb on the liner plate is rule or irregular small rut structure, and monoblock liner plate surface is wavy entirely.When liner plate was installed on the ball mill barrel, by the polylith ball grinding machine lining board that is formed by connecting, the usage quantity of riveting plate can be with four (or being determined on a case-by-case basis), as shown in Figure 3.

Claims (1)

1, a kind of ball mill honeycomb fashion all-wave shape non-bolt liner plate, comprise liner plate body (1) and on sphere honeycomb (2) and groove (3), it is characterized in that liner plate is full wavy surface, liner plate one end face (B) has riveting plate (4) for the other end, plane is middle recessed formation two facets (A) between liner plate and the liner plate.
