PROTECT BLEND CONSISTENCY THROUGH EVERY TRANSFER

Reduce unnecessary disturbance while protecting ingredient condition.

Different particle sizes, densities and shapes can respond differently during conveying. UniTrak selects the conveying method, feeding and discharge arrangements around the complete mixture. Reducing unnecessary transfers and mechanical disturbance helps protect the blend as it moves between process stages, with actual-material testing available to assess its behaviour.

COORDINATE FEEDING AND DISCHARGE

Review how material leaves the supply vessel and enters the next process, as well as its movement through the conveyor.

MIXTURES CAN COMBINE VERY DIFFERENT MATERIAL BEHAVIORS

Many blended products contain ingredients with substantially different physical characteristics. The conveying system therefore has to accommodate the behavior of the mixture as a whole rather than optimize for only one component.

Food & Ingredient Blends

Examples may include:

  • Cereal blends
  • Granola and snack mixtures
  • Dry bakery mixes
  • Seasoning blends
  • Powdered food mixes
  • Grain and seed mixtures
  • Nuts, inclusions and dried ingredients
  • Sugar and ingredient blends

Common concerns: These products may combine fragile pieces, powders, granules and ingredients with very different densities.

Animal Nutrition & Feed Blends

Examples may include:

  • Premixes
  • Mineral blends
  • Feed ingredients
  • Pelleted and granular mixtures
  • Nutrient blends
  • Additive-containing formulations

Common concerns: The challenge may involve maintaining ingredient distribution while handling materials that differ in particle size, density or flow behavior.

Chemical & Specialty Powder Blends

Examples may include:

  • Powder formulations
  • Granular chemical blends
  • Additive packages
  • Pigment-containing mixtures
  • Dry process blends
  • Multi-component specialty products

Common concerns: Containment, dust control and consistent transfer can be as important as maintaining the blend itself.

Plastics & Polymer Mixtures

Examples may include:

  • Resin and additive blends
  • Pellets with regrind
  • Masterbatch combinations
  • Powder and pellet mixtures
  • Compounded-material feed blends

Common concerns: Differences in particle size and density can influence how these components move through a handling system.

Mineral & Industrial Blends

Examples may include:

  • Mineral formulations
  • Granular industrial blends
  • Abrasive mixtures
  • Dense and light component combinations
  • Specialty process materials

Common concerns: These applications may combine segregation concerns with abrasion, dust or high bulk density.

            WHERE MIXTURES CAN BEGIN TO SEPARATE

            Blend consistency is influenced by more than the conveyor itself. The way material is introduced, moved, transferred and discharged can all affect what reaches the next process.

            Feeding

            If ingredients enter the conveyor inconsistently, the conveying system cannot restore the original formulation automatically.
            Consider: Hopper behavior, bridging, surging and uneven withdrawal can change the composition of the material entering the conveyor before conveying has even begun.

            Conveying

            Acceleration, vibration, repeated mechanical interaction and differences in particle behavior can influence how a blend moves.
            Consider: The goal is to avoid unnecessary disturbance while still achieving the required capacity and conveying route.

            Transfer Points

            Transfers often deserve particular attention.

            Long free falls, abrupt changes in direction and uncontrolled discharge trajectories can allow ingredients with different sizes or densities to separate.

            Consider: Reducing unnecessary transfers can simplify the material path and reduce another source of variability.

            Discharge & Downstream Handling

            The blend still has to leave the conveyor and enter the next process consistently.

            Discharge height, receiving hopper design and downstream flow behavior can all affect how the material redistributes after conveying.

            Consider: The complete transfer should therefore be considered as one system.

            MIXTURES & BLENDS CONVEYING FAQ

            Why do mixtures segregate during conveying?

            Ingredients with different particle sizes, densities, shapes or surface characteristics can respond differently to gravity, vibration, acceleration and air movement. Those differences can allow components to redistribute as the material is fed, conveyed, transferred or discharged.

            Can a conveyor guarantee that a blend will not segregate?

            No. Blend behavior depends on the material and the complete handling process. The goal is to select and configure a conveying approach that avoids unnecessary disturbance and reduces opportunities for separation while meeting the required process conditions.

            What makes one mixture more difficult to convey than another?

            Large differences in particle size, bulk density, shape, flow behavior or fragility can increase the likelihood that ingredients will behave differently during handling. Fine particles mixed with larger granules are one common example.

            Does conveyor speed affect blend consistency?

            It can. Higher velocities, abrupt acceleration or unnecessary impact may influence how different particles behave. However, speed is only one factor. Conveyor type, transfers, feeding, discharge and material characteristics also matter.

            Why are transfer points important with blends?

            At a transfer point, material may accelerate, fall or change direction. Components with different sizes or densities can follow different trajectories, creating another opportunity for segregation.

            Can TipTrak handle mixtures and blends?

            Yes. TipTrak carries compatible mixtures in interlocking buckets with controlled movement. Combining horizontal and vertical conveying reduces intermediate transfers, while the infeed and discharge arrangements are selected around the blend and downstream requirements.

            Does TipTrak's relatively low belt speed mean low capacity?

            No. TipTrak uses deep continuous buckets that carry substantial material volume. This allows high conveying rates to be achieved at relatively low belt speeds compared with systems that depend primarily on higher conveying velocity.

            Can Powderflight convey blended powders?

            Yes. Powderflight provides enclosed conveying for compatible powder blends with low product retention. Assess the complete mixture’s response to the aeromechanical conveying action. UniTrak’s Potter Group case includes a source-reported result of no separation of blended products.

            Can a belt conveyor be used for mixtures?

            Yes, depending on the material and application. KleanTrak supports material on the belt and may be worth evaluating where gentle conveying, sanitation or product visibility are important.

            Can UniFlex convey blended materials?

            UniFlex can convey many powders, granules and dry bulk materials. For blends where segregation or product integrity is particularly important, the effect of screw conveying on the specific material should be evaluated as part of equipment selection.

            Can mixtures containing fragile ingredients be conveyed without excessive breakage?

            They can often be handled more gently by selecting a conveying method that limits unnecessary mechanical interaction, impact and free fall. The actual material should be evaluated because fragile ingredients can behave differently within a blend.

            What if part of the blend is dusty?

            Dust may create both containment concerns and mixture-consistency concerns because fine particles can behave differently from larger ingredients. Enclosure, transfer design and the overall conveying approach should be considered together.

            Can material testing show whether a blend will segregate?

            Testing can help evaluate how a specific material behaves in available UniTrak test equipment and may reveal separation, flow or discharge characteristics that are difficult to predict from specifications alone. It does not guarantee identical behavior in every full-scale process condition.

            Should the complete mixture be tested or just the individual ingredients?

            Where practical, the actual blend is generally more useful because the interaction between ingredients is part of what determines conveying behavior. Testing requirements and availability depend on the material and available equipment.

            What information does UniTrak need to review a mixture application?

            Useful information includes the material composition, bulk density, particle-size range, required conveying rate, conveying distance, vertical elevation, current handling method, downstream process requirements and the specific problem you are trying to solve.
