Particle size reduction is a crucial initial step in the production of countless end products across all manufacturing industries. Think of wheat that needs to be ground in the production of flour, or rocks and rubble that must be crushed in order to make sand, and pharmaceutical ingredients that need to be finely milled for incorporation into drugs.
Click for larger picture Particle Size Analysis We offer state of the art particle sizing methods, wet and dry dispersed laser diffraction instruments as well as a complete set of air jet sieves. All instruments are calibrated on schedule to ensure that your product is sized per your specification.
The particle size of the product is smaller than that produced by any other method of size reduction. 2. Expansion of gases at the nozzles lead to cooling, counteracting the usual frictional heat that can affect heat-sensitive (thermolabile) materials.
1. Principles of milling bulk solids. Milling is the action of reducing the size of particles thanks to a mechanical action. The mechanical action is submitting the particles to a stress, under the stress, some cracks will appear and subsequently the particle will be broken in different parts.

This article details size-reduction techniques and equipment that may assist you when handling these materials. By J. Peter Clark. Feb 15, 2005
Particle Size Reduction Particle Size Reduction. This page is about the reduction in size of solid particles. For liquid particle size reduction, see our page on emulsification.. Homogenizers are commonly used to reduce the size of solid or liquid particles.
Apr 04, 2019· LASER particle size analyzer : This depends on the laser ray diffraction by the particle. This is suitable for online particle size determination. When the process is going on the particle size can be measured by LASER diffraction technique without the need to halt the manufacturing process.
For the < 9.5 mm particle size reduction for the extraction, there is information about not requiring particle size reduction where the surface area per gram …
Generally used for reducing material to a particle size as low as 180µm (80 mesh) they produce less dust and heat than alternative forms of milling. The gentle grinding action and quick discharge of correctly sized particles ensures tight particle size distributions (PSDs) are achieved.
The high shear action of the Silverson rotor/stator workhead can achieve rapid and uniform milling of both solid and semisolid materials to a low micron size in a single operation.. The degree of particle size reduction will depend on the hardness of the product, but for many applications, the use of a Silverson mixer will dispense with the need for conventional size-reduction equipment.

Particle size reduction: Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder.
Particle size reduction is a key process in laboratories and small scale manufacturing, right through to full size production. Dec can integrate various milling equipment into their process solutions including Dec's crusher, Co-Mill, hammer mill, UMS and Dec's jet mill range.
The conventional methods of size reduction involve mechanical micronization techniques that are simple and convenient methods to reduce drug particle size and increase the surface area and thus ...
WE SATISFY ANY UNIQUE PARTICLE SIZE REDUCTION NEEDS. Particle size reduction improves end product efficiency by increasing the surface area of the materials being processed. The particle size of ground feed ingredients, for example, has a direct influence on subsequent processing and handling of …
As about 99% of the energy for size reduction finishes up as heat, economy in the use of liquid nitrogen is a critical consideration. It is, therefore, desirable, if practicable, to effect a preliminary reduction of particle size in order to reduce the time taken for the material to be cooled by the liquid nitrogen.
Size reduction machines for large particle sizes above 40 mm are known as crushers or shredders while particle sizes below this are processed with mills. The most common mechanisms for the particle size reduction of solids are explained below.
Particle size reduction mills and micronisers capable of manufacturing to the most demanding specifications. The controlled reduction of a material's particle size by milling, grinding or micronising to achieve the required end product is a vital commercial process.
