Gate Mixers

Transkem fluid mixers gate type agitators are generally used for low speed, high viscosity duties.

A gate mixer impeller would typically be used up to viscosities of up to 50,000 centipoise. A viscosity greater than 50,000 centipoise can be mixed by a double start helical ribbon as mixing efficiency reduces when the Renolds number is very low. The gate mixers impellers are designed specifically to meet each application and vessel size. Similar to top entry turbine mixers, gate mixers can be made in most materials. The seals & drives can be supplied to suit the customer’s preference or site standards.

Our gate mixers are designed to be a close tolerance to the vessel wall in order to keep the sides of the vessel clear of product or/and enhance heat transfer. Alternatively the impeller may be fitted with hinged scraper blades to clean the side of the vessel.

Gate mixers are excellent aids for heat transfer in more viscous applications where a simple turbine unit would not be efficient.

Similar to contra rotating mixers, gate mixers can be fitted with a top entry emulsifier or most commonly a bottom entry emulsifier for manufacture of creams and emulsions. As with all Transkem fluid mixers the emulsifiers and homogenisers can be supplied to suit the clients preference for drive & seal.

Transkem gate mixers are typically used for mixing shampoos, chocolate, adhesives, creams, flocculants, paints etc…
