WEAR BLOCKS 30

Our wear Blocks combine a number of metallurgical properties into one unique wear resistant material which today has been widely used in most abrasive wear applications. Our wear block is an extremely hard laminated bi-metallic, wear resistant composite, which has a nominal hardness of 700 BHN (HRC 63) minimum. It is produced by combining a highly alloyed chromium-molybdenum white iron and metallurgically bonding it to a mild steel backing plate. The bonding possesses high shear strength of over 200 MPa and will not separate. The alloy s microstructure is made up of primary and secondary chromium carbides which are supported by a hard, finely dispersed Martenstic matrix. The hardness of alloy provides maximum abrasion resistance, while the steel backing plate acts as a means of absorbing high impacts and allows easy fitting and use. Typical applications of wear blocks include Excavator Buckets, Loader Buckets, Dragline Buckets, Face Shovel Buckets, Spider Arm Guards on Crushers, Discharge Chutes, Rock Boxes, Grizzly Bars on Feeders, Shredder and Grinding Mills, Sugar Cane Knife Edges, Adaptor/Attachment Protection, Dredging Equipment, Screen Feed Distribution and Fee Hopper Wear Areas. Wear blocks have been examined and tested for grade, quality, chemical analysis and hardness which guarantee high abrasion and impact resistance. Facts about wear blocks for wear protection: Alloy hardness of HBN700 (HRC 63) for long life Additional carbides of 1500 HV maximize resistance to abrasion Circular and dome design minimizes effects of impact, resulting in less chance of loss Easy to position for effective wear resistance Proven in mining and construction bucket applications Wear blocks are available in any sizes and shape customer wants.the most common ones are: chocky blocks shaped or standard wear bars wear buttons wear donuts shredder/grinder tips cane knife edges boomerangs wear plates wafer strips skid bars 31

Chocky Bars Our chocky wear bars were first in the market about 7 years ago and had been well proved in US and Australia market. Our chocky bars are easy to use. There is no pre-heating or post heating required when welding into place. They are easy to form and weld onto inner and outer contoured surfaces. The versatility of Chocs allows unique layouts to be created on equipment to reduce the effects of abrasion. The backing plate can be supplied with grooves to aid in the forming, bending and cutting of the block. The unique, formable design of Chocs offers effective protection on sliding abrasion in high wear areas for a wide range of applications on fixed and mobile plant equipment including: Wear bars for Buckets Chute Liners Crusher Liners Road planners Rock box ledges Hammer Tips Part No. Type Size Dimension Weight A B C D E F G (kgs) CB251 1 240*25*23mm 240 25 15 8 23 0.9 CB252 2 240*25*23mm 240 25 15 8 23 0.9 CB401 1 240*40*23mm 240 40 15 8 23 1.5 CB402 2 240*40*23mm 240 40 15 8 23 1.5 CB501 1 240*50*23mm 240 50 15 8 23 1.9 CB502 2 240*50*23mm 240 50 15 8 23 1.9 CB651 1 240*65*23mm 240 65 15 8 23 2.5 CB652 2 240*65*23mm 240 65 15 8 23 2.5 CB801 1 240*80*23mm 240 80 15 8 23 3.2 CB802 2 240*80*23mm 240 80 15 8 23 3.2 CB901 1 240*90*23mm 240 90 15 8 23 3.5 CB902 2 240*90*23mm 240 90 15 8 23 3.5 CB1001 1 240*100*23mm 240 100 15 8 23 3.9 CB1002 2 240*100*23mm 240 100 15 8 23 3.9 CB1301 1 240*130*23mm 240 130 15 8 23 5.2 CB1302 2 240*130*23mm 240 130 15 8 23 5.2 CB1501 1 240*150*23mm 240 150 15 8 23 7.3 CB1502 2 240*150*23mm 240 150 15 8 23 7.3 32
