Stevenson Construction Materials - Sealing Chip Plant - Drury, NZ

In 2017 Rocktec complete the Drury Quarry Sealing Chip plant for Stevenson Construction Materials



  • 12x Conveyors
  • 2x Rocktec 16' x 5' Avalanche Screens
  • Rocktec BTM96-R VSI Crusher (520KW)
  • TEREX 20' x 8' Cedarapids Horizontal Triple Deck Screen
  • Produces 5 Graded Chip Products and 1 PAP Product
  • Optional TNZ Production Mode
  • Skid mounted modular type design


The Drury Sealing Chip Plant was constructed in the location of the old block plant. The main feed hopper was refurbished with a new Rocktec Vibrating Feeder as the starting point of the new build. In addition to the BTM-96R VSI Crusher, Rocktec have installed a TEREX 20x8 Triple Deck Horizontal Screen—this provides the large capacity to efficiently screen the main PAP product. All crushed aggregate is then washed and screened to deliver up to five different graded products.

Common wear parts are used throughout the plant to reduce spare stock holdings. The screens feature roll-away front chutes for additional accessibility.
