HD-PRT Gravity Chute Sampler
HEAVY DUTY MODEL

The HD-PRT belt end sampler model of gravity chute sampler from Intersystems provides representative and repeatable samples, employs very simple and reliable operation and uses minimum headroom. It samples fines, small or large particles and works with abrasive materials.
Mounting may be in chutes, hoppers, at belt-end or head chutes. When activated, a slotted sample tube enters the product stream with the slot facing down. While fully extended, the sample tube rotates 270 degrees, taking a representative sample through the product stream. The sample tube then retracts out of the product stream, into the sampler housing and deposits the sample into the discharge. Sample tube can be driven pneumatically or hydraulically.

SAMPLE TUBE OPERATION

- At rest & retracted – tube then begins to enter product stream at the 6 o’clock position
- As the tube moves through the product stream it rotates from the 6 to 3 o’clock position while collecting sample
- After collection, tube retracts back into the HD-PRT sample
- Retracted, the tube rotates back to the 6 o’clock position & releases sample into the chute – ready to repeat
