Sand, Sinter Mix & Building Materials

Moisture Measurement Solutions

Washed sand, sinter mix, wood fiber, and similar bulk materials all need better moisture visibility to protect mixing accuracy, sintering efficiency, board quality, or drying safety. Inline monitoring helps operators adjust faster than periodic sampling can.

Industry Challenges

Key Pain Points

  • Sand moisture changes with weather and disrupts concrete water balance
  • Sinter mix moisture directly affects granulation and bed permeability
  • Wood fiber moisture outside the target range causes later board deformation or brittleness
  • Harsh, dusty environments make stable manual testing difficult

Technical Impact

Why Moisture Matters

  • Continuous values help keep batching and mixing closer to target
  • Better control improves production efficiency and final product quality
  • Replacing periodic checks reduces labor and improves consistency in harsh environments

Process Flow

Moisture Measurement Integration Points

Strategic measurement points across your production process for maximum quality impact.

01

Primary Transfer

Measure bulk material at feed or conveyor stage

02

Drying / Mixing

Track moisture during drying, granulation, or blending

03

Final Conditioning

Adjust water addition or drying intensity from live values

04

Dispatch / Use

Verify moisture before concrete mixing, sintering, or pressing

Case Study

Washed Sand Moisture for Concrete Batching

Challenge

Seasonal and weather-driven sand moisture swings make concrete water addition difficult to control.

Solution

Use online moisture measurement to continuously correct batching water instead of relying only on periodic lab checks.

Result

Plants can improve batching precision, lower labor demand, and keep concrete performance more stable.

Scope

Typical Applications

  • Suitable for washed sand, sinter mix, wood fiber, and other bulk materials with variable surface moisture
  • Supports batching, granulation, drying, and conditioning processes where moisture swings create large downstream errors
  • Works well in heavy-duty sites that need faster control than periodic grab-sample testing

Installation

Recommended Measurement Positions

  • Above conveyor belts carrying washed sand or sinter mix
  • At bulk transfer points before batching, pressing, or granulation
  • At dryer outlets or storage feed points for fiber and board raw materials

Details

Process Control Notes

  • Washed-sand moisture control focuses on concrete batching accuracy, where unstable sand moisture changes the effective water-cement ratio.
  • For sinter mix, moisture directly impacts granulation behavior, permeability, and stable furnace charging.
  • Wood-fiber and board-material applications use online moisture data to avoid warping, brittleness, and later product deformation.

FAQ

Industry-Specific Questions

Drying processes often change faster than laboratory checks can keep up with. In applications such as starch, baking soda, calcium carbonate, ceramics, PVC additives, and washed sand, moisture affects product quality, energy cost, flowability, storage stability, and downstream performance. Online measurement helps operators see those changes during production instead of after the product has already moved downstream.
