Insmart Automated Coal Sample Preparation System

Most ideal and modern system for third-party coal quality evaluation.
Insmart presents a ‘path-breaking’ and completely mechanized Sample Preparation System for large scale thermal power generation units and washries.
Here, collected samples are fed into the automated sample preparation system and the sampling unit performs size reduction, quantity reduction and representative sample drawal steps as per the IS 436 or ASTM D 2013 (depending on Indian and/or imported coal) guidelines and provides a completely mechanized preparation of collected samples.
Adhering to the IS 436 standards the Automatic coal sample preparation unit follows the following (tagged as 1 to 9 in the adjacent 3D image) sequential steps:
1. Primary crushing to -50 mm size
2. Elevating crushed sample & conveying to the divider
3. Sample Division to discard 3/4th increment & retain 1/4th increment
4. Secondary crushing to -12.5 mm size
5. Dispensing 1 Kg moisture sample at -12.5 mm sample size
6. 3rd stage crushing to 3.35 mm size
7. Sample conveying & dispensing sample for pulverization
8. Sample drying in heated conveyor
9. Sample pulverization
