Mobile roller sorter

Reference: RS

The DEMA mobile roller sorters are extremely suitable for sorting potatoes and onions, among other things. The sorting principle is identical to the system of a roller set on the receiving hopper, where the opening is infinitely adjustable. Efficiency is lower than that of a web sorter but the permissible flow rate is much higher. The ideal machine for gross (pre)sorting at a decent speed.

Besides these standard mobile roller sorters, many other versions are possible for cleaning and sorting your product.

Hopper

Hopper

The DEMA hopper is available in many different versions! From a simple hopper without extra modules to an elaborate version with several cleaning and sorting possibilities.

There is no such thing as a standard hopper for us. Configure your own machine on our website or visit us and we will listen to you and build a machine to your needs. Every hopper depends on the type of product, the soil and the objectives of the customer. So we are not talking about a standard hopper, but a custom-made machine, consisting of our standard available modules! If you don't find the module you want, then we sit down and develop the machine with you!
