Maintenance OverviewA construction waste mobile crusher eats rebar-bearing, muddy, brick-laden demolition feed every day, which is harder on equipment than a granite hard-rock line: rebar jams the chamber, mud cakes the mesh, dust is heavy, and the magnet never stops. Its upkeep logic differs from a hard-rock line — the real enemy is not normal wear-part consumption but foreign objects and contamination dragging the whole line down. Below are the daily, weekly, and monthly checklists and a fault...
Project OverviewIn 2024, a downtown redevelopment demolition site in Hanoi, Vietnam produced about 2,000 t/day of demolition C&D waste — concrete chunks and brick mixed with rebar — which crews used to haul to distant landfill at high cost, wasting space. The owner wanted to convert it on site into recycled aggregate for nearby road base and block plants. Vanguard Machinery configured a mobile crushing line to the site conditions; it went into production in Q2 2024 and has run steadily since.1. ...
Field ExperienceAfter visiting demolition and infrastructure sites across a dozen countries, one shift is clear: five years ago everyone hauled C&D waste to landfill; now they install mobile crushing lines on site and turn it into aggregate. This isn't one company's preference—policy, hauling cost and carbon limits together made "resource recovery" a necessity. Below we break it down across demand, region and policy.1. Why demand is hot now- Landfills saturating: perimeter capacity near big citi...
Quick AnswerConstruction waste isn't one "ore" — it's a mixed pile: concrete, brick, mortar, with rebar, wood and plastic mixed in. So you don't size the equipment by hardness; you size it by how much rebar and how much dirt is in the pile. The setup we reach for most often: a jaw up front (takes big lumps, doesn't care about rebar), an impact crusher for the mid and fine stage (concrete breaks into good cubical recycled aggregate), and a magnetic separator in between to pull the rebar out. If t...
As urbanization accelerates and urban renewal projects multiply, construction waste generation continues to climb. In China alone, annual construction waste output reaches approximately 3.55 billion tonnes, accounting for over 40% of total municipal solid waste. Construction waste, however, differs fundamentally from natural ore: it is complex in composition, scattered in distribution, limited in volume per site, and highly variable in particle size and strength. These characteristics create sig...
