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

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

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

## Hammer mill for mustard

- Mills tested with customers' mustard: [MCS 280](https://moinhosvieira.com.br/en/hammer-mill-vieira-mcs-280-5-hp/), [MCD 530](https://moinhosvieira.com.br/en/hammer-mill-vieira-mcd-530-20-hp/)
- Screens used: 0.2 · 0.3 · 0.4 · 0.5 · 0.7 · 0.8 · 1 · 1.2 · 1.5 mm

### Throughput (kg/h)

Measured in the tests:

- [MCS 280](https://moinhosvieira.com.br/en/hammer-mill-vieira-mcs-280-5-hp/): 85 to 240 kg/h · screens 0.4 to 1.5 mm · measured in factory tests with customers' mustard
- [MCS 350](https://moinhosvieira.com.br/en/hammer-mill-vieira-mcs-350-10-hp/): 85 to 850 kg/h (estimate) · screens 0.4 to 1.2 mm · Values projected from factory tests.
- [MCD 530](https://moinhosvieira.com.br/en/hammer-mill-vieira-mcd-530-20-hp/): 74 to 362 kg/h · screens 0.3 to 0.7 mm · measured in factory tests with customers' mustard
- [MCD 680B](https://moinhosvieira.com.br/en/hammer-mill-vieira-mcd-680b-30-hp/): 275 to 2,570 kg/h (estimate) · screens 0.4 to 1.2 mm · Values projected from factory tests.
- [MCD 680A](https://moinhosvieira.com.br/en/hammer-mill-vieira-mcd-680a-60-hp/): 525 to 5,150 kg/h (estimate) · screens 0.4 to 1.2 mm · Values projected from factory tests.
- [MCD 950](https://moinhosvieira.com.br/en/hammer-mill-vieira-mcd-950-100-hp/): 1,000 to 10,300 kg/h (estimate) · screens 0.4 to 1.2 mm · Values projected from factory tests.

Figures from earlier tests with other samples: they vary with moisture, the required particle size and the product. Actual throughput is confirmed in the grinding test.

### Technical notes

- High fat content: feed slowly and gradually, pausing so the air can clear the circuit; plan periodic cleaning stops (for build-up on the sides, remove the screen, close the mill and let the air carry the product to the cyclone).
- Screens below 0.7 mm require cleaning stops; smaller openings increase caking, and pure mustard on 0.4 mm was not feasible.
- A carrier such as starch made grinding on a 0.4 mm screen possible.
- To avoid clogging, the product should stay within 12% moisture and 8% oil.
