- Recommended Mixing Equipment for Carbomers
Carbomers are water-soluble acrylic acid polymers available in dry powder form. Acting as thickening and gelling agents, different grades of carbomers produce a wide range of viscosities for suspending insoluble ingredients and stabilizing emulsions.
- Recommended Mixing Equipment for Catalytic Slurries
Catalytic slurries consisting of solid catalysts and support materials suspended in a liquid medium are commonly prepared in batch tanks agitated by low-speed mixers such as propellers, anchor paddles and pitched blade impellers. These devices can sometimes suffer from long cycle times and inadequate dispersion especially in large batches.
- Recommended Mixing Equipment for Graphite Dispersions
Graphite, a highly conductive crystalline form of carbon, is used in a wide range of products, from batteries, heat sinks and solar cells to coatings, lubricants and composites.
- Recommended Mixing Equipment for Milk Powders
Dissolving powders like milk, whey, cocoa, sugar, thickeners and stabilizers into liquid can be a processing challenge. Conventional batch mixing systems commonly suffer from long cycle times, floating powders, lump formation and excessive foaming.
- Recommended Mixing Equipment for Fumed & Precipitated Silica
High surface energy silicas require adequate shear for optimal dispersion into liquid. Improper powder wet-out and insufficient mixing lead to decreased efficiency (i.e. higher loadings of silica needed to achieve the desired properties)
- Dissolve solids rapidly.
Consider high-speed sub-surface solids injection for demanding and high-volume dissolution requirements..
- Eliminate floating powders
Consider high-speed subsurface powder injection to eliminate floating powders and stubborn lumps in your mixing operation. Technologies such as the ROSS Solids/Liquid Injection Manifold (SLIM) are highly efficient at maximizing yield as a result of faster and more complete solid dispersion.
- Reduce cycle time in your large capacity mixer.
This bulletin discusses a method of raw material handling and addition that simplifies large capacity mixing and can reduce cycle times by up to 80%..
- Streamline your mixing process
Installing an inline powder injection system with large batch tanks can significantly reduce cycle times, simplify clean-up and maintenance, enhance batch-to-batch consistency and improve overall production efficiency.
- Optimize powder injection in your batch mixer.
Solids dispersion remains to be one of the most formidable processing challenges even today. A new high speed powder injection system described in this bulletin is ideal for dispersing hard-to-wet powders into liquid without agglomeration,floating or dusting..
- Dust-free mixing of pigments
A common issue in dispersing pigments into liquid is dust generation. Charging solids into an open, top-agitated vessel inherently causes lightweight powders to become airborne. Using a high shear mixer equipped for sub-surface powder induction helps minimize dusting, maximize yield, improve dispersion quality and accelerate production.
- Improve safety in your mixing
This bulletin discusses some practical and technical solutions for improving safety in the mixing area..
- Reduce foaming and air
entrapment during mixing.
Foaming and air entrapment are common phenomena encountered in many mixing processes. Different applications call for different solutions, including addition of chemical defoamers, mixing under vacuum and high-speed sub-surface powder induction..
- Accelerate bulk powder dispersion into liquid.
An inline rotor/stator mixer equipped for powder induction is ideal for high speed mixing of bulk solids into liquid. Aside from high throughput, benefits include ease of operation, mobility and simple maintenance.
- Select a powder induction mixer that can serve multiple mix tanks of virtually any size.
An inline rotor/stator mixer equipped for powder induction offers flexibility, capability and portability to serve multiple mix vessels of virtually any size. Its straightforward operation and convenience further maximize equipment utility while simplifying material handling.
- Eliminate “fish eyes” in your mix.
Inefficient mixing can lead to agglomerates and “fish eyes” which are difficult to disperse once formed. Using a high shear mixer equipped for powder induction helps prevent the formation of agglomerates, maximizes yield and cuts cycle time.
- Use of powder induction mixing technology can significantly reduce raw material costs.
Many batch mixing processes can be optimized with the addition of an inline rotor/stator mixer. The supplemental agitation and shear provided by an inline mixer boosts production by reducing cycle time. Multiple batch tanks can be serviced by a single inline mixer and benefit from its pumping capabilities. Another practical advantage to an inline mixer is that it is easily installed without disturbing pre-existing equipment.
- Eductor-less solids induction systems offer improved processing reliability
In traditional eductor-based powder induction systems, balancing the performance of the main components -- pump, eductor and mixer – often requires a skilled operator and can prove to be difficult. A high speed powder injection unit utilizing just one device to perform all three functions is simpler to use and offers a more reliable performance.
- Apply high speed solids induction to eliminate dusting in the mixing area
The release of airborne particles into the plant atmosphere when powders are added to a mix vessel leads to significant maintenance costs and safety concerns. A high speed induction device can eliminate dusting and accelerate both production and process changeover.
