Perforated Metal for Grain Industry

Perforated metal sheets are widely used in grain industries for drying, cleaning and screening.

Grains Drying

In grain drying machines, the air continuously passes through the perforated metal sheets, keeping the grain fresh and drying quickly. By improving ventilation in grain bins, grains can remove moisture quickly and prevent bacterial growth. Therefore, grains are stored in good conditions as seeds, thereby leading to greater grain yield.

Grains Cleaning

Perforated metal grains cleaning machine will remove straw, chaff, weed, seeds, soil, rubbish and other unwanted materials, so that it improves the storability of crop, reduce price penalties at time of milling and improve milling output and quality.

Grains Screening and Sifting

When storing grains, impurities such as debris, pebbles, and particles may be mixed in. Hammer mill screens, by determining the holes size of the perforated sheet mesh according to the size of the grain to screen the impurities out, smaller materials such as weed seeds, soil particles and stones can be sieved from the grain through a smaller sized screen, so that perforated metal screens will ensuring the cleanliness of the grains.

Hole Types and Hole Size

Because of the shapes of the seeds or grains, the round holes and oblong holes are working at higher efficiency and then required widely. Qinghe Metal Mesh can make the holes from 1mm to 30mm, we are pleased to find the right solution to your needs, keeping on making precision and uniformity quality for grains industry.
