Description
P/00/0 11 Regulation 3.2 AUSTRALIA Patents Act 1990 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title: "A LINER COMPONENT FOR USE IN MINING AND QUARRYING INDUSTRIES" The following statement is a full description of this invention, including the best method of performing it known to me/us: A liner component for use in mining and quarrying industries FILED OF THE INVENTION This invention relates to liner component for use in mining and quarrying industries. This invention further relates to wear and impact resistant liner component for handling lumpy ore/materials in mining and quarrying industries. BACKGROUND OF THE INVENTION AND PRIOR ART. The materials that are used to withstand load and consequently wears, are presently rubber, cast, white iron alloys and various grades of abrasion resistant liner. However, no suitable material is known, which can be used for resistance of lumpy ore/materials. Therefore, the need exists to provide materials for use in liner components, which are abrasion resistant and impact resistant to lumpy materials and are also suitable rigid. OBJECTS OF THE INVENTION. It is an object of this invention to provide liner components, which are abrasion resistant, wear resistant and rigid. It is another object of this invention to provide liner components, which have greater life and are thus economical. A further object of this invention is to provide liner components, which can save the mother plates of the chutes or hoppers from damage. These and other objects of the invention will be apparent from the ensuing description. BRIEF STATEMENT-OF THE INVENTION. According to this invention, there is provided a wear and impact resistant liner component for use in mining and quarrying industries- comprising a rubber matrix rigidly supported on a steel plate, said rubber matrix having been provided with a plurality of steel strips spaced apart from each other. 1 The other features of the invention are as follows: (a) the said steel plate is provided with a plurality of pilot holes designed for fixing the liner component with the mother plates of chutes/hoppers used for handling solid materials. (b) counter holes are provided in the rubber matrix for the purposes of fixing and plugging. (c) the said steel strips are vertically inserted into the rubber matrix. (d) in one modification ,rthe lower ends of the steel strips are supported on the steel plate. (e) In another modification, the lower ends, of the steel strips lie close to and above the said steel plate. (f) the number of and spacing apart of the steel strips are designed based on the lump size of the material being handled. BRIEF DESCRIPTION OF THE INVENTION ACCOMPANYING DRAWINGS. The invention is now described with reference to the accompanying drawings in which Fig. 1 shows a plan view of the liner of the invention. Fig. 2 shows a part sectional view A-A of one type of the liner of the invention showing steel strips inserted into the rubber and supported on a backing steel plate.. Fig. 3 shows a part sectional view B-B of another type of the liner of the invention showing steel-strips inserted into the rubber, short of the backing steel plane and Fig.4 shows a part isometric view of the liner. DETAILED DESCRIPTION OF THE DRAWINGS. It will be seen from figure no (1), that the liner (1) and made of wear and impact resistant rubber has rubber portion (2) and longitudinally provided steel strips (3) shown in dotted lines. There are thus provided 'a plurality of such steel strips at pre selected places according to requirements and exigencies of the situation. The manner in whuich these steel strips are provided are shown in more detail in figures (2), (3) and (4). Figure no (1) also shows in dotted lines counter holes (4) provided on the rubber for fixing and plugging. 2 There are also pilot holes (5) on the backing steel plate more clearly shown in the other figures. for fixing with mother plates of chute/hopper which are the equipment of handling materials, and the main equipments on which the components according to the invention are used. Figure no( 2) shows an embodiment of the invention in front cross section . It shows the rubber portion (1),backing steel plate (2), vertically inserted steel strips (3) fixed to the steel plate and supported on the same. This figure also shows the counter holes (4) and pilot holes (5) clearly. Figure no ( 3 ) is slightly different from figure no (2) in that the steel strips are terminated a little distance away from the steel plate and are thus not supported on the steel backing plate. Figure no(4) is a part isometric view of figure no (2). The components are mainly used for resistance to lumpy ore/materials upto 3-4 ton lumps with velocity. They ensure greater life compared to other liners as on date. They save the mother plates of chutes and hoppers from simultaReous damage and reduce the overall cost. Principle of the working of the liner of the Invention. After the lumps on hit the steel-strips, the acting force will be divided into various directions. Only perpendicular force will be on the steel strips and other shearing forces will be absorbed by rubber due to its dampening properties and will resume its original shape due to its elasticity. There will be little or no wear and no permanent deformation. The total impact force is thus neither acted on the steel strips nor on the rubber. Steel-strips and rubber both take the share of forces. In case of floated steel strips with rubber, perpendicular force will also be transmitted to rubber. Steel strips ensure that the rubber is not cut through during operation. 3
