Cryloc Rotary Screens

It’s hard to imagine the grain and bulk processing industry without the use of the Cryloc rotary screens. In the cylindrical housing one or two specially formed screens separate the fine particles from the incoming product. Maximum 10% fines at the inlet results in less than 1% in the finished product (fines are smaller than 2/3 of the pellet diameter). The wide capacity range makes the Cryloc rotary screen an essential sifter for the dry cereal processing industry.

The two screen decks are specially designed for hammer mills, which grind on different sieve perforations, or in combination with a crumbler.  In the sieve feed of the two screen decks is an electro-pneumatic operated valve which can rotate between the upper and lower screen. The process control is also provided with sensors for position feedback. An automatic cleaning with compressed air keeps the screen perforations clear of obstructions.
