The High Speed Disperser (HSD) is the single most important machine in any paint factory. Without proper pigment dispersion at 1200–1500 RPM, paint has poor coverage, grit and colour inconsistency. IPCS recommends the exact HSD specification — motor size, tank volume, blade type — for your specific paint type and daily output. Learn more about our machine recommendation service.
| HSD Type | Tank Volume | Motor | For Which Factory |
|---|---|---|---|
| Fixed Shaft Small | 200–500 L | 5.5–11 kW | Starter, distemper, primer |
| Fixed Shaft Medium | 500–1000 L | 11–22 kW | Small emulsion, putty slurry |
| Hydraulic Medium | 1000–2000 L | 22–37 kW | Mid-scale emulsion, enamel |
| Hydraulic Large | 2000–5000 L | 37–75 kW | Large-scale paint factory |
Pigment Dispersion
Wets TiO2, fillers and pigments into base at 1200–1500 RPM. Essential for colour development, coverage and batch uniformity.
Pre-Mix Function
Combines water phase, thickener and dispersant before bead mill stage in premium emulsion production.
Right Sizing Critical
Wrong HSD size = batch rejection or wasted energy. IPCS calculates exact specification after understanding your product and output.
Frequently Asked Questions
What is the correct HSD size for my paint factory?
Depends on batch volume, product viscosity and daily output. For 500 L/day emulsion: 500–1000 L tank HSD (11–22 kW motor). For 2000+ L/day: 2000 L hydraulic HSD (30–45 kW). IPCS calculates the correct specification after reviewing your factory requirements.
What is the difference between fixed shaft and hydraulic HSD?
Fixed shaft HSD has a non-adjustable blade height — suitable for consistent fill levels and smaller batch sizes. Hydraulic HSD has a pneumatic/hydraulic ram for raising/lowering the shaft — suitable for variable batch sizes and easier cleaning.
Why is HSD mandatory for every paint factory?
Every paint type requires proper pigment wetting and dispersion to achieve uniform colour, hiding power and stability. Without adequate HSD processing, paint shows grit, poor coverage, colour separation and settling.
What RPM does the HSD operate at?
Standard operating speed: 1200–1500 RPM at the disc tip for pigment dispersion. Pre-mixing and let-down can be done at 200–400 RPM. IPCS SOP specifies speed for each production stage.
What blade design is correct for paint?
Standard Cowles tooth blade (8-tooth sawtooth) is most common for pigment dispersion in paint. IPCS specifies blade diameter as 1/3 of tank diameter for optimal dispersion efficiency.
Can one HSD handle multiple paint products?
Yes — same HSD can be used for different products by adjusting blade speed and mixing time. IPCS SOP specifies operating parameters for each product to avoid cross-contamination.
How to maintain a High Speed Disperser?
Daily: clean disc and shaft after each production run. Weekly: check seal for leaks, inspect motor bearings. Monthly: lubricate bearings, check electrical connections. IPCS provides a maintenance schedule as part of machine setup.
What is the motor rating needed for an HSD?
For 200–500L tank: 5.5–11 kW. For 500–1000L: 11–22 kW. For 1000–2000L hydraulic: 22–37 kW. For large-scale: 37–75 kW. Motor rating determines disc speed and shear force at the dispersion zone.
Can HSD be used for wall putty production?
HSD is used for pigment pre-dispersion in wall putty paste before transfer to the ribbon blender for dry powder mixing. It is not used as the main machine for dry powder putty — a ribbon blender handles that stage.
Is there a local manufacturer for HSD in India?
Yes — trusted HSD manufacturers are based in Ahmedabad, Mumbai and Pune. IPCS recommends specific manufacturers based on quality track record and after-sales service in your region.
