CRAB - Calibrated Reagent Applicating Blender
The CRAB is a
technically advanced active dosing system meeting strict calibration
requirements and should be treated as a scientific instrument.
Specifications &
Dimensions
 |
A CRAB can be made to suit your
requirements. |
|
The CRAB can be designed for un
manned operation. |
|
A standard
machine dimension are 2.35 metres high x 1.25 metres wide x
3.05 metres long
|
|
weight (empty) =
1250kg |
|
Complete Stainless Steel
Construction |
|
Specialist machines to suit site
applications. |
Dustless Hopper Filling System
The CRAB
has a dustless hopper filling system that allows extremely alkaline reagents
such as calcium hydroxide & calcium oxide to be 'loaded' with out skin
contact. A remote bag opener is activated to release the contents of the
bag.
Calibrated Flow
|
In order to ensure absolute
accuracy with calibration of reagent, a number of influencing factors
must be known - |
-
Belt speed.
-
Auger speed.
-
Water flow through the machine
-
Laboratory results.
|
All of the above lead to a Mixture
Ratio. |
Liquid Reagent Introduction System
|
The use of liquid reagents such as sodium hydroxide require extreme
caution and exact calibration. This issue has been effectively addressed
by fitting a second container that houses the reagent. The reagent is
then introduced at necessary intervals via the calibrated taps and injected
into the impeller housing ensuring complete mixing. |
|
The Liquid Reagent Introduction System can be manufactured to relate to
job size. |
Fail Safe Shut Down
|
The CRAB is designed to shut down via the low oil pressure system
essentially shutting down the generator leading to shutting down all systems.
|
|
The Fail Safe System contained include - |
-
Earth leakage on electrical system.
-
Low water level - sump.
-
Variator over speed.
-
Extreme alkalinity probe.
Types of Applicators
|
The CRAB can encompass such activities as - |
-
High volume treatment.
-
Remote drain spraying.
 Quad
bike with remote sprayer.
 25metre Sprinkler Spread
-
Remote hose spraying.
Semi submersible boom spray.
-
Dams - rivers - drains - roads - rock faces.
 Float attachments for use in large water areas.
-
Mass circulation of water bodies.
-
Artificial Sumping
Transport Options
The CRAB is designed to be fitted to any number of
transport systems to access all sites including -
Government and Agri-business have become aware of
decreasing water quality on coastal strips below 5 metres AHD.
The problem on the coastal strips has been
identified by acid run off due to oxidation of acid sulphate soils.

tonne bag cutter shown.
A bag of
chemical fits straight in, the lid is closed and the contents empty directly
into the hopper ready for calibrating before dispersing via the chosen output
method.
