Bespoke low temperature drying equipment.

Based in Wickhambrook, near Newmarket, family owned BG Europa (UK) Ltd have provided specialist drying plants for many industries, including dryers for aggregates, sand, slag, mineral, glass and recovered aluminium.

With increased demand BG Europa are well positioned to offer a range of aggregate drying equipment which include the SD Series of Parallel Flow Dryer Drums. At the top of the range is the SD 1.5 which are usually mated to the SF Series of Pulse Jet Fabric Filters to provide efficient low temperature drying at just above dew point. These drums are used extensively within the slag and sand drying industries and therefore flight design and drum construction are targeted to provide long operational life given the highly abrasive nature of these materials.

BG Europa Rotary Dryer Drums benefit from many years of design and experience of a diverse range of drying applications, where each dryer unit is designed to suit individual applications and requirements. Where additional versatility is required elements can be incorporated to allow dryer inclination and drum speed to be easily adjusted to suit the differing drying characteristics of a range of materials.

The SD 1.5 drying drum ensures long life expectancy and low operational costs by offering a heavy-duty chassis in stationary or relocatable designs.

A high specification drum shell is manufactured from 12.0mm thick boiler plate which is resistant to flaking under cyclical temperature conditions.

High efficiency flight pattern including insulation flights in the combustion zone to maximize radiant heat capture incorporate adjustable drum flights to enable the material veil to be modified to suit extraction and burner characteristics.

Trunnion assembly design:

The trunnion assembly consists of two trunnion rings forged from a solid billet of EN8 steel and machined to tolerance to provide a trunnion path free from joints.

The incorporation of pivoting trunnion roller support stools enables tracking by skewing the trunnion roller tangentially to the trunnion ring. This design ensures that the trunnion rollers have full face contact with the trunnion ring at all times, thus ensuring even distribution of forces over the roller and trunnion ring for minimum wear. This design is particularly beneficial when using nylon rollers which can be damaged by point loading.

BG Europa heavy-duty trunnion roller assemblies incorporate internal taper roller bearings to lock all thrust forces into the roller assembly. This design significantly reduces forces on the trunnion shaft and negates the need for keyways which are traditionally a source of weakness.

BG Europa trunnion rollers are manufactured from EN8 steel with flame hardened wearing faces for maximum life.
