Sand Moisture

Sand processing can have its difficulties when it comes to moisture control as too much can cause clumping and inconsistencies while too little can create excess dust and out of spec product, all of which puts a strain on cost, energy and wasted product.

MoistTech manufactures a state-of-the-art moisture analyzing system that can be mounted directly onto the line to provide a continuous reading of the moisture levels in the entire product. The sensors can be mounted throughout the process to control the moisture at any point, allowing the user full control over the final product quality. Sand Moisture 1

Installation

The IR-3000 sand moisture sensor should be mounted several inches above the conveyor, before and after the dryer. This will allow the user to continuously monitor the process and can control the glass moisture content either manually or automatically in the manufacturing process.

If the IR-3000 has to be installed close to the dryer outlet where it will be susceptible to extreme heat conditions, it is necessary to cool the sensor with either air or water.

Benefits of Sand Moisture Detection

  • Low Cost & High Accuracy Results
  • Improved Product Quality Monitoring
  • Lower Energy Costs & Less Waste
  • Total Process Optimization
  • NIR Technology – Outperforms Competing Technologies
  • Less Downtime
  • Low to Zero Maintenance
  • Fuel Consumption & Water Savings
  • Efficient Dryer Control

MoistTech’s technology can rapidly control the drying system resulting in quality spec sand without wasting time, energy, and money. Our quality sensors are designed for the harshest of installations; a simple Plug-and-Play operation by mounting 4”-12” above the moving product, we can measure with a repeatability of 0.1% moisture or better.

Dryers are much more efficient when the input moisture content is consistent. The moisture content of the sand entering the dryer varies constantly. Typical sand stockpiles can vary from 2%-8% moisture. This variation in the stockpile sand results in heating inadequacies wasting energy, money and out of spec sand.

Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. Typical accuracy is about ±0.1% moisture. Typical analog range is 1-10% moisture. The outputs can be adjusted to optimize PLC or recording requirements.
