Trials on a laboratory bead mill help to define grinding parameters – such as bead size, agitator speed and grinding time – before a product moves to a production bead mill. KRS builds laboratory bead mills alongside its High Energy Bead Mills for production.
PRODUCTS – LABORATORY BEAD MILLS
Laboratory Bead Mill Manufacturer in India
KRS laboratory bead mills for formulation development, trial grinding and small batches – the laboratory counterpart to KRS High Energy Bead Mills.
OVERVIEW
What is a laboratory bead mill?
A laboratory bead mill works on the same principle as a production bead mill: an agitator moves grinding beads in a closed chamber, and the beads reduce the particle size of a pre-dispersed product. Its small chamber makes it suitable for formulation development, quality control and trial grinding with small sample quantities.
HOW IT WORKS
How a laboratory bead mill works
Grinding chamber
The pre-dispersed sample is fed into a small closed chamber filled with grinding beads.
Bead motion
An agitator sets the beads in motion; impact and shear between them break particles down.
Separation
The beads stay in the chamber while the ground product is collected.
CONSTRUCTION
Machine construction and key features
A KRS laboratory bead mill combines a stainless steel grinding chamber with an agitator driven by a motor on a steel base plate with adjustable feet. The sample is charged through a stainless steel feed hopper; a return line from the chamber outlet leads back over the hopper so that the product can be recirculated, and a dial thermometer on the line shows the product temperature. Pipework connections are made with clamp fittings.

What is a laboratory bead mill?
A small bead mill for formulation work and trial grinding. It reduces the particle size of solids dispersed in a liquid on the same principle as a production bead mill, with a much smaller grinding chamber.
What is a laboratory bead mill used for?
For developing and testing formulations, grinding trials with small sample quantities, quality control and preparing the transfer of a product to a production bead mill.
Laboratory or production bead mill – which do I need?
A laboratory bead mill is for development, trials and small batches; a High Energy Bead Mill is for continuous production. Many manufacturers use both: trials on the laboratory mill, production on the larger machine.
Can laboratory results be transferred to production?
The grinding principle is the same, so laboratory trials help to define parameters such as bead size, agitator speed and grinding time for production. The transfer is evaluated for each product.
What information is required for a laboratory bead mill quotation?
Your product and application, viscosity and solids content, typical sample or batch size, target fineness and any requirements of your laboratory.
