Screening machine hoses

In this area we would like to support you in selecting the suitable hose for use in screening machines. In the following we have compiled an initial selection of the most suitable hoses for use in various screening machines such as vibration screening machines, tumbler screening machines and plansifters. Depending on the product type, our polyurethane hoses for screening machines are either antistatic (AS), food safe (FOOD) or both (FOOD-AS) and are marked accordingly in the product name. Further important information on screening machine hoses can be found below.

Hoses for screening machines

Applications and properties:
NORRES has developed the PROTAPE® PUR-C 335 FOOD-AS FLAT especially for use on screening machines. The abrasion- and vibration-resistant polyurethane hose has a food-safe and permanently antistatic wall. Thus the 335 FOOD-AS FLAT can be used for the transport of food as well as in explosion hazard areas . It does not matter whether it is used on vibration screening machines, tumbler screening machines, plansifters or windsifters, the PROTAPE® PUR-C 335 FOOD-AS FLAT is characterised by a very long service life and flexibility.
As alternative products we offer further hoses. These include in particular the PROTAPE® models PUR 301 AS (XLD), PUR-INOX 330 FOOD-AS (LD) and PUR 330 FOOD (LD).

Frequently asked questions:
Which hose type is used on tumbler screening machines?
For this, the hose PROTAPE® PUR-C 335 FOOD-AS FLAT can be used.

Why should hoses be resistant to microbes?
In non-microbe-resistant hoses microbial contact may occur on contact with organic materials such as soil, whereby the hose is then no longer usable.

Technical details and standards:
All antistatic hoses which are presented in this section have the following properties:
• Permanently antistatic wall: according to ISO 8031 electrical and surface resistance < 109 Ohm
• Certified according to TRGS 727 and ATEX 2014/34/EU
