Bunny Tierernährung GmbH in Melle produces feed for small animals. The company's product portfolio includes ten premium quality varieties of hay, or instance, as well as a complete range of basic feed and snacks for bunnies, hamsters and other small animals.

Problem

During processing of hay feed, the delivered hay balls are automatically opened, screened and transported for packaging. Because the dust content in the feed needs to be kept as low as possible, operating technicians at Bunny were looking for a concept for dedusting the hay and grass on the (completely enclosed) screening and conveyor system, as close to the point where it was produced as possible.

Solution

Ruwac suggested vacuuming the dust from the enclosure, using a deduster from the modular DS 6 series. This series was designed with the goal of extracting floating dust, and reliably collecting even very small particles. The large filter surface area ensures low differential pressure and long filter service lives, without cleaning. The three-phase drive is designed for efficient, continuous operation.

Since organic dusts can be highly flammable in certain concentrations with oxygen in the air, the DS6 series is primarily produced in a dust-explosion protected design (zone 22).
