Fristam Powder Mixers, Shear Blenders and Colloid Mills are engineered for controlled, closed-system chemical processing. Smooth product-contact surfaces, sealed construction and corrosion-resistant stainless steel support safe handling of hazardous, corrosive and high-purity chemicals.

Yes. Fristam mixing systems are available with:

• ATEX-rated configurations
• Hygienic, 3A approved design (for fine and specialty chemicals)
• FDA-compliant materials where required
• ISO 9001 manufacturing
  This supports compliance with chemical plant safety, quality and environmental standards.

Yes. Fristam chemical mixers are fully CIP-capable and can be cleaned without dismantling. This supports safe product changeovers between batches and prevents cross-contamination in multi-product chemical facilities.

Yes and no. Direct powder induction helps to prevent dust release and vapor escape, improving operator safety and reducing the risk of explosion, inhalation or environmental contamination. ATEX-certified components are available where required. However, certain chemical powders and liquids are naturally unsuitable to be mixed – your Fristam representative will guide you on this.

Fristam mixers are used for a wide range of chemical powders and additives including:

• Polytetrafluoroethylene (PTFE) powders
• Fertilizers
• Calcium carbonate
• Carboxymethyl cellulose (CMC)
• Bentonite and layered silicates
• Micro-capsule powders
• Zeolite and aluminium hydroxide
• Pigments, fillers, polymers, resins and functional additives

These are commonly used in lubricants, drilling fluids, polyurethane production, coatings and speciality chemical formulations.

Powders are introduced directly into a controlled liquid stream, where immediate wetting and high-shear dispersion eliminate floating powders, fisheyes and undissolved particles.

Yes. Hydrophobic powders such as PTFE, electrostatic materials, fine pigments, polymer powders and thickeners are dispersed efficiently without floating or clumping.

Yes. Materials, seals and elastomers can be selected to withstand certain acid solutions, solvents, alkali solutions and abrasive mineral slurries such as calcium carbonate and silicates.

Inline powder induction ensures complete wetting and uniform distribution of solids, producing stable, homogeneous chemical formulations from batch to batch.

Yes. Controlled dispersion prevents settling, floating and concentration gradients, reducing formulation variability and rework.

Yes. High-shear dispersion delivers consistent colour, particle distribution and rheology in paints, inks, coatings, polymers and polyurethane systems.

Yes. Fristam powder mixers and shear blenders integrate easily into new or existing chemical process systems including blending skids, reactor feeds, slurry preparation and inline formulation.

Once installed, Fristam systems operate automatically with minimal manual input, improving safety, repeatability and process control.

Closed powder handling reduces dust, vapor release and manual bag tipping, lowering exposure risks and improving environmental control. Waist height operations means operators do not need to climb ladders to tip powders into a tank style design.

Inline powder induction delivers faster dispersion, better product quality and safer handling than manual powder addition to open tanks. Agglomerates cannot stick to tank walls and contaminate batches.

Yes. Efficient powder induction and closed transfer significantly reduce material losses during addition and mixing, helping to maximise the amount of valuable pigments, polymers and specialty chemicals that end up in the final product.

Lower energy consumption, reduced rework, minimal maintenance and long service life help reduce overall operating costs.

Fristam mixers are used in:

• Lubricants and additives
• Drilling fluids and emulsions
• Polyurethane production
• Paints, coatings and inks
• Detergents and surfactants
• Polymers, resins and speciality chemicals
• Biodiesel
• Soap stock production

Yes. Each system is engineered based on powder behaviour, viscosity, temperature, chemical compatibility, abrasiveness and safety classification.

Key data includes powder type, particle size, liquid phase, throughput, viscosity, temperature, chemical compatibility and ATEX or safety requirements.
