The classic:
coarse and fine grain screening
In coarse or fine grain sieving, all particles that are above or below the desired grain spectrum and are thus too large or small for further processing are sieved out. These coarse and fine fractions are separated as reject grain and disposed of. In some cases, they can be fed back into the product process or recycled. Coarse grain and fine grain sieving have two main objectives:
Best possible processability of raw materials and intermediate products if they have to be available in a certain grain size in production process.
Ensuring the quality of the end product immediately before packaging by screening out unwanted coarse and fine particles.

Do you need more details?
This is how you get the best results in
sieving out coarse and fine grains!
High separation precision depends on…
the type of sieve movement,
the retention time and optimum distribution of the product on the screen mesh, and
the precision of the sieve insert or sieve mesh.
Enough sieve surface for a high throughput depending on…
the grain size of the product being sieved,
the properties or sieving behavior of the product,
the sieving process and
the throughput capacity to be realised
Grains sticking? Our sieve cleaning systems ensure maximum permeability of the sieve mesh:
balls
triangles
ultrasound

Project highlights
Coarse and fine screening
Oversize and undersize screening in pharmaceutical production
Screening pellets – sounds comparatively simple. However, when it comes to pharmaceutical pellets in sensitive production environments, it quickly becomes challenging.
Sorting oversize and good grains: efficient separation process for PVC
One processing step in the production of S-PVC is oversize separation and dust removal. Find out here how we solved this task with the JEL Freischwinger.
Separation of coarse and fine grain before tea filling
Various types of tea are to be freed from small dust particles and breakage as well as from larger foreign bodies before packaging – and this as gently as possible. Find out how we solved the task with the JEL Freischwinger linear stroke screening machine in this project example.
