Perforated Metal Processing Screens

Large range of screens for all kinds of crops. Sefar Metal Mesh offers the largest range of perforated patterns for pre-cleaning. Screens that gently and thoroughly remove unwanted materials from all kinds of crops such as corn, grain, seed, maize, rice, legumes etc. Available in a wide range of precision slots and round hole perforations in various thicknesses and materials for your specific needs.

Pre-cleaning

• Cleaning will improve the storability of crops, reduce price penalties at the time of milling – and improve milling output and quality.
• Grain cleaning – Cleaning will remove straw, chaff, weed, seeds, soil, rubbish and other unwanted materials.
• Screening/sifting – Smaller materials such as weed seeds, soil particles and stones can be sieved from the grain through a smaller-sized screen.

Sefar Metal Mesh can provide you with screens in both galvanised and stainless steel with optimal airflow and strength. We guarantee high-quality and effective processing while still being
cost-effective.

We supply high-quality screens to make your processing more effective – and we always provide you with professional advice on your choice of perforation patterns and materials to optimize the process and your costs. The design of the screen affects the airflow – and the airflow rate affects directly the drying rate. We can tailor-make to virtually any design required.

Sefar Metal Mesh supplies high-quality screens to match your demand with the latest perforation technology to optimise production costs.

Optimal storage

Grain drying is a critical step in preparing the crops for storage. The drying and cooling process prevents the germination of seeds and inhibits bacterial growth. Air carries moisture away from the grain, and higher airflow rates give higher drying rates. The ability of a screen to move air through the grain will depend upon the screen design.

For the complex separation process, the quality of the perforation is extremely important for the final product quality and efficiency! Therefore, precision, efficiency and tight tolerance levels are common for all our solutions followed up by professional service and advice. We offer a variety of commercial screens that make it cost-effective to achieve uniformity in the size and shape of all kinds of crops. This could include gravity tables, rotary, indented cylinders and length graders screens.

Trieur Screens

Metal Mesh Trieur sheets are one of the most important components within specialist machinery that sizes/sorts grain and seeds or separates them from foreign bodies. In order to achieve the best results the correct shape of ‘pockets’ is vital. We are able to deliver sheets with almost any size of ‘pockets’ – round, flat or combined types. Moreover, the sheets can be supplied as flat plain
sheets cut to size or as rolled and welded cylinders. We offer you Trieur in mild and stainless steel. Or Trieur is developed with a minimum of spacing between the ‘pockets’ to provide the maximum sorting/sifting per square metre – for you to maximise your productivity!

Seed Cleaning and Grading

Seed cleaning – malformed, discoloured, germinated, broken, contaminated with other species or mouldy grains in seed lots can severely impact seed quality, viability and vigour and thereby the market value.

Seed grading – for commercial seed processing, seed grains should have a uniform size and weight. A variety of commercial equipment can be used to achieve uniformity in seed size and shape. These include gravity tables, rotary screens, indented cylinders and length graders.

We can offer you a specialist range of screens for hammer mills. We can offer you maximum open area screens to provide maximum throughput and lifetime. We can offer the world’s largest variety of screens and sizes. Two different types of perforation patterns are designed to optimize the throughput and lifetime of your screen, normal round hole perforation and Perfocon.

SCREEN DESIGN FOR HAMMER MILLS

There are many ways to reduce the particle size of cereal grains for feed ingredients. One of the most common ways is to use a hammer mill. The open area in a hammer mill screen determines
the particle size and grinding efficiency. The screen must be designed to maintain its integrity and provide the most possible open area. Screen openings (holes) that are aligned in a 60-degree
staggered pattern optimises the open area whilst maintaining screen strength.

Perfocon

The special product Perfocon which offers specially shaped holes that allow easy exit of particles through the screen – even with small holes in thick material. A unique product in order to obtain a perfect result in the milling process. Special production techniques enable a sheet to be produced with a thickness many times greater than the hole diameter. We offer Perfocon in mild, galvanised and stainless steel.

We produce high-quality screens that are reliable and effective for malting processes. We can offer you screens according to your specifications in stainless steel produced with high precision high
speed equipment to secure optimal quality and production efficiency.

After many years in the processing business, we have developed a broad range of high-performance screens for all kinds of crops. Moreover, we will always be able to meet your demands with tailor-made solutions with more than 30,000 patterns at our disposal. As your solutions provider, we always strive to provide you with the optimal solution. Contact Us to order perforated processing screens in Australia and New Zealand.
