Key TakeawaysNo single cone crusher cavity type covers every aggregate grade. Pick the right cavity and the crusher delivers capacity at a reasonable load; pick it too coarse or too fine and you get bridging, excess return, unstable gradation or fast liner wear. Selection comes down to three things: maximum feed size, target product size and the screen return ratio. Vanguard Machinery's cone crusher line spans coarse, medium and fine cavities so you can match the cavity to the aggregate spec.1. ...
Key TakeawaysA vibrating screen is not the "star" like a crusher, but it decides the quality and output of your finished material. Oversize it and you waste capital and floor space; undersize it and screening is incomplete, material piles up and the whole line loses efficiency. Size it scientifically from capacity, deck area, deck number, aperture, material and installation together — not just the nameplate tonnage of one unit. Vanguard Machinery's YA series circular vibrating screen covers grad...
Key TakeawaysFor abrasive hard rock - granite, basalt and river stone - primary crushing almost always starts with a jaw, not an impact crusher. But there is no single "best model"; it depends on max feed size, target capacity, product size, material and whether the line is fixed or mobile. For most granite, basalt and river-stone jobs, a heavy jaw on primary, a cone on secondary and a screen is the most practical setup. Common machines across scales are the 6CX European jaw crusher and the PE-s...
Key TakeawaysProducing four aggregate grades at once — 0–5 mm, 5–10 mm, 10–20 mm and 20–31.5 mm — is not a matter of picking one crusher by "final size." You design the whole circuit from rock type, max feed, target gradation, shape, capacity and closed-circuit screening. A jaw takes primary; a cone or impact does secondary/fine; a sand-making machine shapes and tops up manufactured sand; multi-deck screens split the finished grades. Multi-stage closed-circuit crushing and screening usually cont...
Executive SummaryModular-mobile crushing and screening plants occupy the middle ground between a fixed production line and a wheeled or crawler mobile unit. They are delivered as bolt-together, skid- or container-mounted modules that a crew can assemble on a shallow foundation and relocate when the working face moves. This technical article explains how such a plant is structured, how material flows through it, and which components actually do the work - from the feeder and crushing chamber thro...
Executive SummaryThe 6CX European jaw crusher from Vanguard Machinery is the primary crusher at the head of a stationary crushing line: a moving jaw squeezes feed against a fixed jaw, taking mine-run boulders down to a top size the cone or impact stage can swallow. Its deep chamber, low nip angle and forged eccentric shaft let it eat big feed, survive hard rock and make a more cubic product. Below we take the machine apart - structure, principle, parts, performance and maintenance - and set it a...
Expert OpinionThere is no single best crushing form. In the field across a dozen countries, Vanguard Machinery (a Chinese-made crushing and grinding equipment brand) keeps seeing the same pattern: the cost of picking the wrong format is rarely the equipment price. It is the project that starts trapped from day one — either it cannot be moved when the pit shifts, or the civil works quietly crush the cash flow before ramp-up. The real rule is simple: understand project life, relocation frequency a...
Project OverviewA 120 t/d iron ore mine in Mongolia, on a water-scarce plateau with long cold seasons and little water access. The owner ran only an old dry separator - low concentrate grade, poor recovery. In 2025 they awarded us the full dry beneficiation line, with the core aim of balancing crush and dry grind so the iron minerals liberate well without over-grinding, using no water at all. This is a typical dry-grinding case for a water-short mine; we give re-computable design parameters belo...
Maintenance OverviewI have seen too many stoppages, and eight of ten are the same neglect: bolts left loose, points left unlubricated, passages left uncleaned. The costliest was a Cebu impact crusher whose blow bar snapped, 8 hours down — that day's lost output would have bought half a year of wear parts. Make the lists below a habit and downtime drops sharply. Three things matter: track tension, lube points, screens and electrics.Daily Checklist- Walk-around before start: track, lines, bolts fo...
Key takeaways:The CI6X Series Impact Crusher is a horizontal-shaft impact crusher built for the coarse and medium crushing stages of large aggregate and mining lines, where shape and cost matter as much as tonnage. Its involute crushing chamber delivers a more cubical product and a high reduction ratio in a single pass. It fits soft to medium-hard, low-abrasive rock such as limestone, dolomite, weathered rock, construction and demolition waste, and coal. For hard abrasive rock like granite, basa...
