Powder Blending System Design & Installation
Turnkey blending rooms: ingredient intake, weighing, mixing and packing, designed and installed as one system.
Klausen Process Machinery designs and installs complete powder blending systems: the mixer, and everything around it that makes it work safely and efficiently. Platforms and stairs, bag lifters, bag tip stations, bulk bag dischargers, conveying, dust collection and controls are designed together, built in our Kings Park, Sydney workshop and installed on site by our own team.
Most blending problems are not caused by the mixer. They come from how ingredients get to it and how the blend leaves it: operators lifting 25 kg bags overhead, dust escaping at the charging point, slow manual weighing, or a mixer that cannot discharge cleanly into the packing line. We solve those problems as one project, with one point of responsibility.
What a KPM blending installation includes
Platforms, mezzanines and access
- Operator platforms and mezzanines sized around the mixer, bag stations and maintenance access

- Commissioning and training. We run your product, fine-tune the system and train operators and maintenance staff.
- Service and spares. Ongoing support, spare parts and maintenance across Australia.
Who we work with
Food and beverage, dairy and infant formula, nutraceuticals and supplements, pharmaceuticals, chemicals and detergents, and plastics compounders. Projects range from a single mixer with a platform and bag lifter to complete blending rooms with conveying, dosing and packing.
Why KPM
- One contractor for the whole system. Equipment, steelwork, installation and commissioning under one scope.
- Since 1998. Decades of powder handling projects for Australian manufacturers.
- Local workshop and team. Design, fabrication and service from Kings Park, Sydney.
- New or used equipment. We can build a project around quality used mixers from our own stock to cut cost and lead time.
Frequently asked questions
Can you add a platform and bag lifter to our existing mixer?
Yes. Many projects start with an existing mixer. We design the platform, bag station and lifter around it.
How long does a blending installation take?
It depends on scope. A platform and bag station can be installed in days; a full blending room is planned over several months, with on-site work scheduled around your shutdowns.
Do you work outside Sydney?
Yes. We install and service equipment across Australia.
Can you reduce dust in our blending room?
Yes. Enclosed charging, extraction at every open transfer point and pneumatic conveying are the usual fixes.

What makes a good powder blending system?
A powder blending system is judged by a few simple outcomes: every batch meets specification, operators can work safely without heavy lifting, dust stays where it belongs, and the line produces the volume you need with a predictable cost per tonne. The sections below look at the decisions that shape those outcomes, from batch or continuous operation to the level of automation, weighing accuracy and how the finished system is proven before handover.
Batch or continuous blending?
Most Australian food, chemical and nutraceutical plants use a batch powder blending system: a measured quantity of each ingredient is loaded into the mixer, blended for a set time and discharged as one lot. Batch operation suits frequent recipe changes, traceability by batch number and products with many minor ingredients.
Continuous blending uses feeders to meter each ingredient at a controlled rate into a continuous mixer, producing a steady stream of finished blend. It suits high volumes of a small number of recipes, such as feeding an extruder or a packing line that runs all day on the same product. A continuous powder blending system depends heavily on the accuracy of its loss-in-weight feeders, because there is no batch mixing step to even out errors.
3 levels of automation for a powder blending system
- Manual with engineered handling. Operators weigh ingredients on floor scales and tip them at a bag station on a platform, using a bag lifter. The mixer has simple start, stop and timer controls. This is often the best first upgrade from fully manual work, giving large safety and dust improvements for modest cost.
- Semi-automated batching. Major ingredients are conveyed and weighed automatically into the mixer from bulk bags or silos, while minor ingredients are still hand-added at a prompt from the control system. Recipes, batch weights and mixing times are stored in the PLC and each batch is recorded.
- Fully automated. All ingredients are dosed by feeders or weigh hoppers, the mixer cycle runs to recipe, and the blend is discharged and conveyed to packing without operator intervention. Operators supervise, refill and handle exceptions.
The right level for a powder blending system depends on batch numbers per shift, the number of ingredients, labour availability and how critical traceability is. Many sites start at the first level and design the layout so the powder blending system can move up a level later without being rebuilt.
Weighing and dosing accuracy
Blend quality can never be better than the accuracy of the ingredients going in. In a powder blending system there are three common ways to weigh:
- Weighing in the mixer on load cells, adding each ingredient until the target weight is reached. Simple, and well suited to major ingredients.
- Weigh hoppers above the mixer that receive ingredients by conveyor or feeder, then discharge the full batch together. This frees the mixer to blend while the next batch is being prepared.
- Separate minor ingredient weighing on precise bench scales or dedicated feeders, because small additions such as vitamins, colours or actives need tighter tolerances than the bulk ingredients.
Matching the scale or feeder resolution to the smallest addition is important in any powder blending system. A large platform scale that is perfectly adequate for 500 kg of flour may not be accurate enough for 200 g of a premix.
Choosing the mixer for your powder blending system
The mixer at the heart of a powder blending system is selected from the product properties, batch size and mixing quality required. Ribbon blenders suit most free-flowing powders, paddle mixers are gentler on fragile or mixed-density ingredients, conical mixers handle sensitive products and small minor additions, and high-shear mixers are used where liquids must be dispersed or agglomerates broken down. Our guide to powder mixer types compares them, and our powder mixers page shows what we supply.
Proving the powder blending system at commissioning
Commissioning is where the design is confirmed with your real products. During installation and commissioning, KPM checks that each machine runs correctly on its own, then runs the complete powder blending system with product.
- Mechanical and electrical checks, including guards, interlocks and emergency stops.
- Calibration of load cells, scales and feeders against test weights.
- Mixing trials, with samples taken from several points to confirm blend uniformity and set the mixing time.
- Throughput trials to confirm the line achieves the required batches per shift.
- Operator and maintenance training, with documentation for cleaning and routine checks.
Preparing for a powder blending system quotation
The more we know about your powder blending system at the start, the more accurate the proposal. Before a site visit it helps to gather:
- A list of ingredients with bulk densities, packaging type and approximate usage.
- Batch sizes, batches per shift and planned growth over the next few years.
- Product data sheets and safety data sheets, particularly for combustible or hazardous powders.
- A floor plan or photos of the area, with ceiling height and column positions.
- How the blend will be packed and any traceability or recording requirements.
Reducing hazardous manual tasks is often a key driver for a new powder blending system. Safe Work Australia’s model code of practice for hazardous manual tasks is a useful reference when setting priorities. For room-level planning, read our guide to planning a powder blending room.
More powder blending system questions
Can a powder blending system be automated later?
Yes, if it is planned for. Leaving space for weigh hoppers, conveying lines and control upgrades allows a manual system to be automated in stages.
Batch or continuous: which is better?
Batch blending suits frequent recipe changes and traceability by batch. Continuous blending suits long runs of a few recipes at high volume.
How do you check that the blend is uniform?
During commissioning, samples are taken from several points in the mixer at set times and tested, confirming the mixing time needed for a uniform blend.
