Why Hydraulic Ram in an Internal Mixer?

5 Comments

In internal mixers, hydraulic ram assembly is an apt replacement (over pneumatic ram) because they improve rubber compounding quality.

In pneumatic rams, pressure may vary while the hydraulic version ensures constant, reproducible ram pressure. When you cut compressed air, operating costs reduce because you remove the central compressed air requirement in your plant. You also remove the maintenance issues associated with these air systems in the process. This leads to energy savings in your operations.

A constant pressure from hydraulically actuated rams eliminates variations in ram pressure caused by varying compressed air-supply to the mixers’ pneumatic cylinders. Hence, these are more efficient than air compressors for application of sustained batch-mixing pressure. This in turn, provides consistent mixing process conditions that enhances product uniformity – all of which leads to improved mix quality.

The hydraulic rams can be fine controlled with the hydraulic power. The result is shorter mixing cycles, higher productivity and improved batch-to-batch consistency. Further, the hydraulic ram reduces the noise level within the vicinity of the mixer. So, apart from improving the work environment they use less energy and are quieter in operation.

In intermeshing type of mixers, cooling water passed through ram provides extra cooling. This control feature is critical when processing heat-sensitive compounds.

Please remember, this is a technology upgrade. Hence, when you choose your tangential and intermeshing mixer, you need to ask for this option. Else, you may continue to receive manufacturer’s standard pneumatic ram only.

Existing pneumatic ram on your internal mixers can be converted to hydraulic ram. Internal mixer manufacturers like HF Mixing Group, Kobelco, Bainite Machines, etc can guide you with energy-saving data for your mixer and offer conversion at an optimized investment.

  5. good article..got an idea about the difference of pneumatic & hydraulic rams.Also it’s better to mention the advantages of pneumatic ram than the hydraulic..Just an idea. keep it up. 🙂
