Dual Valves releases eDart’s coarse sampler for mining and mineral processing

Dual Valves Australasia announces a new coarse sampler designed for process
slurry sampling applications in the mining and mineral processing industry.

The eDart coarse sampler is a robust poppet sampler specifically
designed for the mining industry’s coarse and abrasive slurries, handling
solids of up to 12mm in the slurry. eDart meets composite or shift sampler

Used to provide samples of slurry from cyclone feed lines, tails lines
and other mineral processing areas, the coarse sampler is pneumatically
operated, stroking the sampler head into the process line or sampling chamber
to trap a fixed volume of process slurry. The sampler then retracts fully to
allow the sample to discharge at atmospheric pressure through the outlet or
drop directly into a container.

eDart coarse samplers feature an integrated design with only one moving
part in the entire sampling cycle. The sampler can handle 400ml sample volume
per cycle and is typically used for calibration of densitometers and control
purposes in mineral processing.

Key features and benefits of eDart coarse samplers include line pressure
not exposed to the atmosphere when the sample is released at atmospheric
pressure; design head stroke of 70mm; 50mm barbed outlet at the bottom for
mining hose connection or to simply drop sample directly into a container; process
pressure rating up to 800 kPag; and extremely rugged stainless steel
construction, featuring a tungsten carbide piston plate and polyurethane
sampling chamber for increased wear resistance.

The eDart coarse sampler is optionally available with an integral flanged
sampling chamber for slurry to be piped from the sample point to another
location for ease of access/operator convenience. Typically used when the
sampling point is inaccessible or inconvenient to reach, the sampling chamber also
comes with an integral mounting bracket designed for ease of installation onto
site structural support.

Options available for the eDart coarse samplers also include actuated
and manual isolation valves to suit individual applications; integral timer
module for standalone control; PLC control with local panel mounting to control
timing and frequency, as well as sequence of operation in conjunction with
actuated isolation valves; proximity switch for fully retracted sampler head indication;
filter regulator set to pneumatic actuator; and solenoid valve to the pneumatic
