Produits principaux

Concasseurs à cône

Our cone crushers use a conical crushing chamber: the mantle spins and crushes rock against the fixed bowl liner. The output is cubical aggregate with a tight size distribution. We build standard and short-head models for secondary, tertiary and quaternary stages, depending on your feed size and what you need to produce.

Concasseurs à mâchoires

Jaw crushers crush with two opposing jaws: one fixed, one moving. They handle primary crushing of hard, abrasive rock and give you coarse, angular aggregate. Our single-toggle design includes hydraulic CSS adjustment on the larger models, so you can change the gap setting quickly when the feed changes.

Foire aux questions

?De quels matériaux sont fabriquées vos pièces de concasseur ?
Wear parts are manganese steel, usually Mn18Cr2 or Mn21Cr2. In service the surface work-hardens from about 200 HB up past 500 HB, which is what gives the wear life. Bushings are C93800 and C93700 bronze, centrifugal cast. Gears are 20CrMnTi or 18CrNiMo7, and shafts are forged 42CrMo.
?Vos pièces sont-elles compatibles avec les concasseurs OEM ?
Yes, they are built to the original specifications. We are a manufacturer, not a reseller, so the parts are cast, forged and machined in our own facilities using our own patterns.
?Combien de temps prend la livraison ?
Stock items leave in 3 to 7 days. Standard production runs take 14 to 21 days. Large castings or custom orders need 30 to 45 days. If you have an emergency breakdown we can arrange express shipping.
?Expédiez-vous dans le monde entier ?
Yes. We export to mines and quarries all over the world. Regular orders go by sea freight, urgent ones by air. Full customs documentation is included.
? I don't have a part number. Can you still help?
Usually yes. Send us the crusher make and model plus a photo or a dimensioned sketch of the part. We can identify it from our pattern library, or reverse-engineer it from a sample if needed.
