Moinhos Vieira manufactures industrial hammer mills for grinding citric acid, serving everything from small operations to large-scale industrial processes.

Our equipment is successfully used for the particle size reduction of citric acid, allowing different levels of grinding according to the needs of each process.

With extensive experience in industrial grinding, we carry out practical tests with citric acid to evaluate equipment performance and help select the most suitable solution for each application.

Technical notes

  • Automated feeding (screw, vibrating chute or belt) gives steadier output; manual feeding lowers capacity.
  • For less dust and more whole granules, combine a suitable screen with reduced speed (frequency inverter).

About citric acid grinding

Citric acid is an organic acid that is a component of all aerobic living organisms – most abundantly, and not surprisingly, in citrus fruits. This weak acid has been used as an additive in processed foods for over 100 years as a preservative, a bitter flavor or an emulsifying agent.

Due to its effective preservative properties, citric acid can be found in most canned and processed foods.

Moinhos Vieira has several customers who use its  mills for citric acid grinding.
