Longer wear life – lower cost per ton with JYS Casting’s gyratory crusher wear parts
The JYS Casting primary gyratory crusher wear parts have the most important role in rock size reduction in mine operations as the crushing process starts from a primary crusher. The highest possible wear life is combined with mechanical reliability through the component life cycle. As the production stops are very expensive for mine operations, the JYS Casting manganese gyratory crusher wears are easy and quick to install.
Manganese steel mantle wear parts are provided with different shapes, surface profiles, and steel grades. Alloy steel, white iron, and manganese steel concave wear parts are designed for hardest rock in surface and underground operations.
JYS Casting has applied the same engineering problem-solving to gyratory crushers which have proven so effective on cone crushers. We went into the field and studied the many areas for potential improvement: poor nip of feed material, excessive wear in the lower crushing chamber, poor throughput from partially worn parts, excessive wear metal discard costs and problems with uneven or localized wear. We’re the leader in gyratory crusher liner innovations, and it’s a rare crusher which cannot show significant gains in production and wear life from a Columbia analysis and improved wear parts.
Gyratory spares – the genuine alternative
The JYS Casting product range of precision machined replacement parts to suit gyratory crushers includes complete mainshaft assemblies, mainshafts, cores, spider assemblies, spider bushings, spider seals, topshell assemblies, bottom shell assemblies, eccentric bushings, shell bushings, mainshaft nuts, spider rim liners, spider shields, dust seal rings, retainers, step washers, piston wear plates, pinion shafts, shell bolts and many more.
Furthermore, our premium range of primary gyratory crusher manganese steel and alloy castings are proven in mining and aggregate production applications worldwide.
JYS Casting Concave Segments
Pin or Key Concaves
Tapered dowel pins are driven between concaves forcing them outward to make contact with the top shell and create even spacing. The key concave has parallel sides and is easily removed with a wedge. Once the key concave is out, the remainder is easily removed.
