With over 30 years designing and manufacturing experience in the Australian market for the Australian Market we have learnt that the highest form of design is "simplicity without compromise" and no range better exemplifies that value than our extensive range of
Machines are made to order and clients are encouraged to come and inspect their new equipment as it moves through the manufacturing process. Precisionscreen's extensive range is designed as modular components and we can easily customise to suit the client's needs, no square pegs for your round sandpit.
Our equipment includes dry or wet screen box stations, bucket wheels, screws, weirs, cyclones, dewatering screens, barrel washers, filters, sumps, tailored solutions you need for your sand washing process.
The SRD240x has been designed to provide a mobile solution for new and existing sand washing projects.
The road towable chassis allows the plant to be moved via prime mover easily with minimal set-up costs normally associated with sand washing plants.
The SRD240x requires a clean water source supplied to the 3 inch inlet manifold for the washing screen deck and a 10 inch waste water pipe discharging from the machine to a settlement pond. The machine is packed full of features that makes this the perfect tool for testing sand deposits out cost effectively to give you measurable results before investing in a full plant. The SRD240x is fed via additional conveyor with dry material from another source.
The plant has the ability to make up to 3 different sand grades at the same time.
Features:
8x5 two deck rinser screen
Wash kit fitted both top and bottom
Dual bucket wheel dewaterer with variable speed
High frequency dewatering screen
Submerged screw with variable speed
44.8m Galvanised weir area
250mm Cyclone with rubber lined pump
Cyclone on a swing allowing it to be stockpiled separately
Road towable chassis
Engine hydraulic powerpack on-board runs all components
Single or double discharge points for sand via screw conveyor
The SRD180 Dewaterer is used to collect sand particles from slurry material fed from a wet screening process.
The SRD180's primary job is to pick up the heavier particles of sand as they sink to the bottom upon entry to the tank via the feed tubes. The very efficient poly bucket inserts allows water to drain from the sand discharging it at the other side onto a stockpiler. The plant allows for excellent settlement time of the finer particles. The under water screw drags these particles back to the buckets for collection. The organic material floats to the back of the tank with the silty water and is dealt with by a 44.8m (linear) weir that eventually allows effluent water to escape out the 10 inch discharge pipe back to pond.
Features:
Galvanised inlet chutes (two off)
Ability to make two size Sand fractions
Galvanised bucket wheels with poly inserts
Submerged screw for fines conveying back to bucket
Option of single or twin discharge chute for washed sand
Large adjustable Weir 44.8m linear
Large dewatering capacity
Buckets and screw variable speed with individual control
Wheel mounted with tow bar for site movement
Galvanised legs for operation mode
Option of 10x5 screenbox attached to Dewaterer as one complete unit
Fines recovery Pod is used at the end of the sand washing process to help dry (dewater) the sand from a previous stage or concentrate on recovering the fine sand from the waste water before going back to Pond. Fine Sand recovery is achieved via the on-board 250mm Cyclone fed by the rubber lined pump that collects feed material from the base of the tank. The Cylcone then discharges the heavy particle (ie fine sand) onto the high frequency dewatering screen for draining. The newly recovered sand can then be deposited to the side of the unit (via screw) or out the front of the Pod onto a Stacker. This sand discharge point is optional depending on Pod Configuration.
Features:
Vibrating dewatering screen
250mm Cyclone with rubber lined pump
Cyclone is on a swing that allows fine material to stockpiled separately
Cyclone pump and screen driven hydraulically
Large weir area for effluent water 44.8m linear
Optional discharge point from dewatering screen
Designed to work in conjunction with Precisionscreen Sand Washing products
The Precisionscreen Barrel Washer is designed to scrub and clean natural pebble or crushed aggregate.
The Barrel Washer circuit can be used in conjunction with a Precisiosncreen feed hopper to form a standalone circuit or be incorporated into an existing plant set-up. Ideal feed size for the Barrel is 50mm minus but it can handle up to 150mm size rock. The feed material then enters the feed box on the Barrel washer where a large volume of water forces the material into the rotating Barrel. The internal lifters help agitate, scrub and clean the rock creating a rock on rock cleaning action, assisted with the injection of fresh water via the internal spray bar that's runs the length of the barrel. Retention time inside the barrel is controlled via the variable speed controller ranging from 1-10 RPM. Material discharges onto to the 2.4m long mesh Trommel for final cleaning and draining of dirty water. The mesh on the outside of the Trommel is cleaned via a spray to help prevent blinding before material is discharged of the chute.
Precisionscreen Barrel Washer
Features:
4x independently hydraulically driven wheels to rotate the barrel
10mm heavy duty Rubber Lining in the barrel with 12 lifters
Enclosed barrel length 4m long with 1.5 diameter
Heavy duty skid mounted frame
2.4m long rotating trommel at the discharge end to help drain dirty water away
Internal spray bar runs the entire length of the barrel adding clean water
Spray bar on the outside of the mesh to keep it clean from build up
This plant can accept material from any drying screening process delivered via conveyor belt or a Cyclone mounted above the screen.
Can make up to three different sand fractions and waste material of the front of the wash screen. Cyclone in this case needs swung out away from the machine to make separate product (fine brickies loam).
The water in this set-up has to go through two 44.8m (linear) weirs before discharging to settlement pond.
Precisionscreen offers a wide range of machines available to hire; from track mounted crushers, screens and scalpers we have the right machine to cater for any job.
