LACKEBY GRIT CLASSIFIER GC
High performance grit separation and world class quality
When high efficiency, low costs and reliability are the priorities
- Grit separation
- Separation of any high-density particles
from process or waste water (Industry).
- Enhances efficiency of separation process
for solid material
- Maximises classifying and dewatering
- Minimizes maintenance.
- Robust design
- Long technical service life
- Shaftless screw conveyor for dewatering and discharge of separated material
- No submerged bearings required.
The incoming water flow is led into the wider section of
the tank through the top-mounted inlet. A vertical plate creates
an even laminar flow, which enables the solid material to
settle. The outlet is positioned in the narrow section of the tank, which is fitted with an overflow channel to reduce the risk of particle migration. The tank walls slope steeply to avoid the risk of bridging.
Settled material is transported out via a shaftless spiral, with intermittently
slowly rotating operation, for maximum dewatering. This shaftless spiral
reduces the need for maintenance, as there is no bearing at the bottom of
As a standard configuration, the classifier is manufactured in stainless steel or acid-proof steel. The unit is fitted with a shaftless spiral made of carbon steel (standard) or stainless steel (option) in the bottom of the through. The throughs are equipped with Hardox wear bars or Robalon wear liners. As additional options the wear liners are available for special applications such as high abrasive materials in mining or metal recycling industries.
