Concrete block brushes

Weber is one of the leading suppliers of special brushes for concrete block production.
Introduced in the early 1970s, Weber’s original strip brush has set the standard in terms of quality and performance. These standards are still valid today. We have been working with leading manufacturers of concrete block producers and concrete block production machine manufacturers for more than 40 years.

Feed drawer brushes KingCon® 2.0

Plastic on the outside, metal wire on the inside, tightly connected to a galvanized steel profile back. To this day, a unique system from Weber. The bristle density is higher than in any other comparable brush. The new generation with optimised bristle anchoring is even more durable than its predecessors!

Weber feed drawer brushes have been designed to withstand the extreme stress occurring during the production process. Our special material mixture, the comparatively high bristle density, the improved fixation as well as the number of bristle lines ensure a consistently high quality of the concrete blocks and a thorough cleaning of the stamp. We offer three different types of brush holders which are attached to the feed drawer.

The unique Weber principle

Powerful double action: The flat wires on the inside are protected and stabilized from the outside by abrasion-resistant nylon bristles. The result: effective shoe cleaning and extended service life.

  • Outer bristles: nylon 2 x 3 mm white / poly 1.2 mm yellow
  • Inner bristles: metal wire 1.1 x 0.25 mm
  • Bristle length: 115 and 85 mm (others on request)

Spiral brushes

Rotary brushes for green products

The spiral-shaped bristle arrangement produces a lateral sweeping movement so that burrs on the side or on the back can be removed more easily. Thanks to the loose spiral shape, this brush can be set deeper than conventional brushes. The effect: the bristles are able to penetrate the gaps between the stones deeper without causing any damage.

Technical specifications:

  • Pipe diameter: 45, 55, 65, 80, and 103 mm
  • Sweep diameter: 150-500 mm
  • Length: up to 2.500 mm
  • Spiral slope: 20 mm (< 100 r.p.m.), up to 50 mm (> 100 r.p.m.) and fully covered
  • Material: premium-quality nylon bristles or standard qualities such as polypropylene

Sweep-out brushes are used to effectively clean bristle heads and interspaces in spiral brushes to prevent mud points or encrustations. The length of the brush carrier and of the bristles, as well as the number of retaining brackets, can be individually adapted to the spiral brush.

Board sweeping brushes

Crust Cracker® 2.0

The optimum cleaning

Crust Cracker® 2.0 provides the highest cleaning performance of any inline system. Its three overlapping plate brushes reach every inch of board surface. 

Depending on operating conditions and the conditions of the production boards the brushes are fitted with the most suitable bristle type: from super aggressive nylon grit to the only mildly abrasive polypropylene. Embedded concrete, encrusted parting agents, grime and rust are eliminated promptly while new build-up is effectively prevented. 

The Crust Cracker® 2.0 operates as a selfcontained, auto-controlled system and will fit existing production lines.

Features

  • for cleaning production boards made of steel, plastic and wood
  • different bristle types available
  • auto controlled system with height adjustment
  • active contact pressure with adjustable rotation speeds
  • better cleaning performance due to higher brush rotation
  • compact design
  • fits existing production lines
  • suitable for dust extraction

As an addition to the Crust Cracker® we recommend the special release agents for production boards from Rhein-Chemotechnik GmbH.

tectol CoatRelease and tectol CoatRelease 2 are environmentally friendly special release agents for production boards in concrete products coating processes. The application of tectol CoatRelease and tectol CoatRelease 2 before coating concrete products significantly reduces sticking of coating material to the production boards.

To the products

  • effective release action
  • easier removel of coating material overspray
  • to be applied easily
  • economical in use
  • readily biodegradable
