Grubb Tumbling System

The innovative engineering of the Grubb Tumbling System (GTS) sets a new standard for tumbling concrete products. The unique rugged design of the GTS minimizes the cost of tumbling concrete pavers, brick and retaining wall units by reducing the routine maintenance required and providing features to maximize profitability and minimize culls.

Design Features

• The tumbler Section Feeding Box (SFB) provides an efficient, cost effective
  method to remove sections of concrete products from the storage pallet
  and gently feed the sections into a tumbler. The cube pusher indexes
  a single section of concrete pavers, brick or retaining wall units into
  the feeding box which slowly tips backward and raises to the top of
  the tumbler. Once at the top the units are gradually fed into the tumbler.
• The spiral steel tumbler drum is submerged arc welded from 3/8"
  steel for maximum rigidity and roundness, providing a long,
  dependable life.
• A long-life rubber lining 2" (51 mm) thick is attached
  to the drum with three hardened steel T-bars. The
  simple design permits straightforward, simple
  replacement of the liner when needed.
• A 24" (610 mm) long hardened steel wearing plate with debris evacuation slots cut at
  45 degree angles at the end of the tumbler allows the product to gently fall from the
  tumbler, reducing breakage as the units fall from the tumbler onto the output conveyor.
  At the output of the drum, a heavy-duty output conveyor transfers the product onto a product
  accumulation turntable for manual cubing.
• Manual or automatic product aligning conveyors positioned at ground level convey
  rows of product to the packaging system.
