A powder that does not flow, packs unevenly or has the wrong particle size creates problems at the hopper, the press and the customer. Our powders testing instruments measure those properties in a plant lab. As powders testing instruments manufacturers in India and suppliers in India, we supply process industries and development labs.
Instruments are grouped by what they describe. Size and surface are measured with the laser diffraction analyzer, sieve shaker and BET surface area analyzer. Density is covered by the bulk and tapped density tester and the helium gas pycnometer. Flow is studied with the orifice cup flowability tester, angle of repose avalanche tester and the shear cell used in hopper design. The halogen moisture analyzer measures loss on drying, and the compaction press shows how the powder behaves in tablets or briquettes.
A first lab often combines sieves, density and moisture tests, adding laser sizing and flow instruments for product development.

Taps a measuring cylinder at fixed rate to find bulk and tapped density, Hausner ratio and Carr index of powders. Used in pharma, food and chemical plants.
Volumetric nitrogen adsorption instrument measuring specific surface area and pore volume of powders. Used by catalyst, battery, pigment and carbon material producers. It also reports pore volume, helping qualify catalysts, carbons and fine ceramics.
Measures particle size distribution of dry and wet powders from sub-micron to millimetre range. Used by pharmaceutical, pigment, cement and ceramic QC and R&D labs.
Rotating drum instrument that records powder avalanche behaviour and dynamic angle of repose. Used to rank flow and cohesion of pharma excipients, toner and food powders.
Hydraulic bench press with instrumented die for compaction studies of ceramic, metal and pharma powders. Measures green density versus pressure and ejection force. It is used to study how pressure affects density and strength of pressed compacts.
Times the flow of free-flowing powders and granules through standard orifices and calculates flow rate. Used in metal powder, pharma and detergent industries. Results are in seconds per 50 g and help compare production lots quickly.
Halogen moisture balance for loss on drying of powders, granules and pastes. Used in pharma, food, chemical and mineral labs for fast release testing. Typical drying takes only a few minutes per sample, far faster than oven methods.
Annular or translational shear cell measuring flow function, cohesion and wall friction of bulk powders. Used to design silos, hoppers and feeders in chemical and food plants.
Electromagnetic shaker that vibrates stacks of test sieves to grade powders and granules. Used in cement, pharma, spices and mineral processing labs. Repeatable amplitude settings give consistent size fractions for QC reports.
Helium pycnometer determining true or skeletal density of powders and porous solids. Used in ceramic, pharma, battery and mineral labs. Helium fills open pores, so the result reflects the real solid density of the sample.

Powder instruments describe physical behaviour common to any dry solid: size distribution, surface area, density, flow and compaction. Pigment instruments are application tests on colourants, like tinting strength, oil absorption and fineness of grind in a vehicle. A pigment plant uses the powder tests for the raw material and the pigment tests for performance in paint, ink or plastic.

The complete Powders Testing Instruments range (10 products), in alphabetical order:
Confirm the size range, for example 0.1 to 1000 microns, and whether dry, wet or both dispersion modules are included. Ask about the ISO 13320 compliance, optical model software, repeatability and how easily the cell is cleaned. Sample quantity, ultrasonic dispersion and the availability of reference standards are practical points.
Tapped density tells how the powder packs in a container, which matters for filling, hoppers and shipping. True density from a helium pycnometer excludes pores and gaps and reveals the material itself, which is needed for porosity or particle sizing calculations. Many labs need both, with USP style tapping and gas supply considered.
If powder arches or ratholes in a hopper or silo, shear testing gives the flow function, cohesion and wall friction used to design hopper angle and outlet size. Check the cell type, annular or translational, normal stress range and sample volume. For simple quality checks, orifice flow or angle of repose may be enough.
Pharma and nutraceutical plants, chemical and fertiliser units, metal powder and 3D printing powder makers, ceramic and refractory producers, battery material plants, food ingredient and detergent manufacturers, and third-party characterisation labs. A usual starter set contains sieves, density tester and moisture analyzer, followed by laser sizing and flowability instruments.
Both come from bulk and tapped density. They give a simple indication of flowability, since a powder that compacts a lot on tapping tends to be cohesive and flow poorly.
It measures the specific surface area of a powder by recording how much nitrogen gas adsorbs on the surface at low temperature. Surface area relates to reactivity, dissolution rate and adsorption capacity.
Sieving suits coarse powders, typically above 45 microns, and is a low cost, traceable method in many standards. Laser diffraction covers fine particles and delivers full distributions, but needs correct dispersion and optical settings.
Yes. The instruments are made in India and supplied to plants and labs across the country and overseas. Technical datasheets are provided for tenders, and installation and training can be arranged.
A halogen moisture analyzer weighs the sample, heats it and records the mass lost as water and volatiles until the reading stabilises. It gives results in minutes instead of the hours needed in an oven.
