About the REMCO VSI Crusher
Vertical shaft impactors work on rock-on-rock or rock-on-anvil principles, so the wear parts are the rotor tips and the anvil ring or crushing chamber lining. The rotor is the heart of the machine: tip condition decides the product shape and the throughput.
Because the wear surfaces see high-speed abrasion rather than heavy impact, these parts are cast in high-chrome grades, and the tip design is matched to the feed gradation and the required product curve.
Wear parts we supply for the REMCO VSI Crusher
- Rotor tips / rotor protection tips — Cr26 · tungsten carbide composite
- Anvils, anvil ring, anvil blocks — Cr26
- Crushing chamber wear plates, cavity liners — Cr26
- Distributor plate, feed tube, feed eye ring — Cr26 · Mn13Cr2
- Rotor assembly wear parts, cavitation plates — Cr26
- Top and bottom wear plates — Mn13Cr2 / steel
Casting materials
| Material | Character | Typical use |
|---|---|---|
| Mn13Cr2 | Work-hardening manganese, good toughness | General quarry and recycling duty, cheek plates, chamber liners |
| Mn18Cr2 | Higher manganese, better resistance to heavy impact | Primary jaws, cone liners on coarse feed, gyratory mantles |
| Mn22Cr2 | Highest toughness of the manganese range | Large primary liners where impact is severe |
| Cr26 / Cr20 (high chrome) | High abrasion resistance, lower toughness | Blow bars, VSI tips and anvils, fine-crushing chambers |
| Bronze | Bearing grade, machined | Eccentric bushings, socket liners, thrust and step washers |
Material is chosen from the feed size, the rock type and the amount of uncrushable material in the stream — tell us how the current liners fail (worn out, cracked, or deformed) and we will match the grade.
How to order
- Send the machine model and part number, or your own drawing, measured sample or photos with dimensions.
- We confirm the profile, material and weight, then quote — FOB Ningbo or Shanghai for sea freight, with an air option for urgent stops.
- Patterns: a large pattern library is already on hand; where there is no pattern we make one (3D-printed pattern with a machined mould).
- Pouring, heat treatment and machining are carried out in our own foundry, then the parts are inspected against the drawing before packing.
FAQ
Rock-on-rock or rock-on-anvil wear parts?
Both are supplied. The chamber lining and the tip design differ between the two configurations, so tell us which configuration the machine runs and we will quote the matching set.
How do I choose between high chrome and composite tips?
High chrome is the standard choice for most feeds; composites are used where tip life is the limiting factor and the feed is highly abrasive. Send us the current life and feed details and we will advise.
Do you supply the complete rotor or only the wear parts?
Wear parts — tips, distributor plate, feed tube, anvils and chamber plates. Rotor assemblies themselves are supplied only against a drawing.
