Bettersize instruments provide test data of particle size distribution and the physical performance of powder so as to contribute to the whole process of pharmaceutical research, development and production. Grain size measurement attaches great importance to the pharmaceutical industry.

Among pharmaceutical products, solid pharmaceutical preparations account for about 70% – 80%. They include powders, granulates, capsules, tablets, powder filling, suspensions, etc. The unit operations involved consist of smashing, grading, mixing, pelleting, drying, preforming, packaging, transportation and storage. In the preparation process, most solid preparations need to be further processed to improve their powder properties so as to meet the requirements of pharmaceutical quality and operation. The grain size analysis of pharmaceutical particles can also affect the release of the drug, thereby affecting its efficacy and toxicity. For example, if the pharmaceutical particles are too large, the drug will not be properly released, and if the pharmaceutical particles are too small, the drug will be released too quickly, which will increase toxicity and the possibility of side effects. Bettersize grain size analysis software can help you solve these problems. Our particle size analyzers, such as Bettersizer S3 Plus, Bettersizer 2600, etc, have been widely used in the pharmaceutical industry for grain size determination.

Bettersize instruments accurately measure particle size distribution, particle shape, powder flowability, tap density, bulk density and porosity. This assists in the whole process of pharmaceutical research, development and production.

We provide customers with convenient measuring instruments and accurate analysis results. The analysis results conform to 21CFR Part 11.

Bettersize particle shape analyzer are widely used in the research, manufacturing and application of all kinds of mining and minerals, bringing favorable profits.

The Bettersize particle shape analysis machine and powder characteristics tester can provide complete physical property analysis and granulometry analysis for the deep processing of mining and minerals, and offer data including particle size distribution, particle shape, flowability, tap density and bulk density, helping you to reduce the cost of mineral processing and control the correct particle grades of products.

If it is mined, particle size distribution measurement in the extraction of useful minerals is an arduous and technically demanding. The ore is blasted or cut and loaded and hauled to the mill for the secondary crushing and grinding which prepares the material for its intended use.

Comminution

In many cases, the valuable minerals are mixed with gangue and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore. During comminution, ore must be ground such that the particles are small enough that each particle consists of primarily one mineral. These particles are then separated to concentrate the mineral product.

Gravity Separation

Gravity separation relies on differences in material mass to separate minerals. Methods include jigs, sluices, spirals, shaking tables, fine particle separators, and hydrosizers and cyclones. Gravity separation is separation based on weight only and is directly affected by particle size since volume is proportional to weight.

Jigging uses pulsed water flow or a similar process to push up ground material. Heavier and larger particles will sink more quickly between pulses and thus tend to the bottom of the jig. Thus, uniform particle size is important to ensure separation by density and not size. In addition, jig operation (length of water pulses) and design will depend on the size of particles being separated. Sluices and spirals rely on the difference between viscous drag and buoyancy for particle separation. This difference is directly related to particle size. Gravity tables use a vibrating platform to separate by particle size and specific gravity. Thus, narrow size distribution feeds result in better separation.

Froth Flotation.

Here the material is separated by surface chemistry. Bubbles flowing through a slurry or suspension will tend to stick to particles with a hydrophobic surface and cause the particles to float to the top of a froth for recovery. Often, particle surfaces are selectively modified so that mineral surfaces are hydrophobic while gangue surfaces are hydrophilic. Particle size is important to the process efficiency. Overly fine particles may be entrained in the bubble flow regardless of surface chemistry, reducing the effectiveness of separation efficiency. Overly large particles will tend to sink regardless of bubble attachment.

Electrostatic and Magnetic Separation

The behavior of a particle under electrostatic or magnetic fields can be exploited to separate particles by type. These fields will induce charges (or magnetism). The resulting forces will cause particles to move depending on particle mass. Thus small particles are moved further than large particles. Furthermore, particle charge is a surface phenomena and the larger surface area of fine particles will tend to have a higher charge. These size effects can lead to separation by size rather than composition. As such, a narrow size distribution often, but not always leads to better separation.

Shipping Product

The final product is often graded and sold as-is or for further processing. Users will want a particular particle size range in order to ensure that their process is optimized. Thus, in the all-important step of selling products, many mines will control particle size and in some cases, particle shape is important as well.

The particle sizing systems below are fully capable of measuring size and shape to assist the user to obtain the optimal size throughout the manufacturing process.

The particle size distribution testing of the food and beverage industry provides necessary data for improving quality and production efficiency.Therefore, particle size analyzer plays an important role in particle size analysis of food and beverage industry. Bettersize laser particle size analyzer has been widely used in the food and beverage industry for its stable performance, high repeatability and accuracy in particle size measurement.

The performance of the food and beverage industry is closely related to the quality and safety of its products. Further challenges include organoleptic quality, guarantee period, stability, process stability and quality control. The morphology of food is various, including solid state, liquid state, powder, powders and viscous emulsions, and some food at the intermediate production stage is in a powder form. The particle size analyzer can provide scientific data to ensure that production in the intermediate and final stages can meet the standards, thereby providing scientific and effective quality control.The performance of the food and beverage industry is closely related to the quality and safety of its products.

The particle size analyzer can provide scientific data to ensure that production in the intermediate and final stages can meet the standards, thereby providing scientific and effective quality control. Bettersize particle measuring systems meet the international standard with high accuracy, which has attracted great attention of customers in the food and beverage industry and has been widely used in the particle size analysis lab such as coffee and other products.

One example where tight particle size control is required is in the manufacture of chocolate. In the first stage, the nibs are ground into a thick paste called the chocolate liquor. The size of the particles in the chocolate mass is now about 100 microns. To avoid a grainy taste in the finished chocolate, another grinding takes place to reduce the particle size to about 18 microns as the tongue can sense grains of 18 microns or larger. If cocoa powder is being made, the chocolate liquor is further processed into pressed cake, and cocoa butter produced. .The chocolate liquor or mass is put into hydraulic presses under extremely high pressure to drain off the clear, golden liquid cocoa butter. The press cake that is left is cooled, pulverized and sifted into cocoa powder. At this stage the chocolate liquor and other ingredients are kneaded together according to the kind and quality of the chocolate being made. The cocoa liquor is mixed with cocoa butter and sugar and this is further refined by reducing the particle size of the added milk powder solids and sugar down to the desired fineness. The Cocoa powder or ‘mass’ is blended back with the cocoa butter (added to promote better mouth feel and reduce the viscosity) and liquor in varying quantities to make different types of chocolate. Lecithin, an emulsifier, which is much cheaper than cocoa butter $2577/ton (£1,577/ton) is also used to reduce the viscosity of chocolate and so reduces the amount of extra cocoa butter that must be added.

The ingredients can be churned together for hours. The resulting mixture is then dried to form a crumb which is ground with more cocoa butter in the next phase to make the thick chocolate crumb into a silky chocolate. This step reduces the particle size of the cocoa mass to 25 to 30 microns. The smoother the chocolate desired, the more time spent in the rolling mill.

No matter which solid, liquid or emulsion you use, the Bettersize particle size and particle shape analysis system can help you to:

● Rapidly test the particle size and particle shape of new formulations, and participate in new product development

● Optimize the powdering and pelleting process

● Control production and ensure the consistency of ingredients

Image Particle Analysis

Most particle size measurement techniques methods are based on the assumption of spherical shaped particles. This hypothesis leads to significant errors in the analysis if the particles are flake or rod-shaped. Especially for such highly form-anisotropic particles, automated imaging provides an excellent alternative for the determination of tailor-made size specifications.

Automated imaging methods for the determination of the particle size distribution of a material offers a fundamental advantage over alternative methods such as static light scattering, sedimentation or sieving: Each particle is photographed individually! This results in several important advantages for the determination of the particle size distribution:

Realistic proportional values also at the edges of the size distribution, i. e. detection of oversized particles or fine particles

Visual assessment of the dispersing state of a sample (dispersing quality, presence of agglomerates)

Calculation of meaningful size parameters, e. g. geodetic length or Feret diameter for fibres, depending on the application

Selection of the appropriate distribution type (volume, number) depending on the particular task

In addition, the individual photography of the particles gives the opportunity to make statistical calculations on the particle shape, which in practice enables further differentiation of materials. For example, form anisotropy, the deviation of the particles from the ideal sphere, often plays a decisive role for their application and further processing – for example, the conveyance or compaction of powders, the influence on the rheology in dispersions or, in addition to the particle size distribution, the roughness of the particle surface plays an important role for the success of shaping or polishing.

The necessity for tailor-made particle size and shape parameters, combined with ever-increasing PC processing power, ensures that automated imaging methods are becoming increasingly more relevant to a market which is 95% non-spherical..

The determination of the particle shape by automated imaging includes 4 basic steps:

1. Image taking

2. Image processing

3. Object detection

4. Classification

The image taking is ensured by special digital cameras, if necessary in combination to a microscope, to enlarge the particles. The particles may be present neutral (e.g. on an objective) or in motion as well. The dispersing (separation) of particles is possible both in dry-mode (e.g. by simple conveying and riddling or by the usage of compressed air) but also in wet-mode in a solvent. An absolutely basic requirement to perform a successful particle shape analysis is high resolution, image sharpness, good sample dispersing resulting in measurement of individual particles and suitable enlargement. More explanation of this expression required etc. Image processing by appropriate software leads to upgraded pictures: for example isolated pixels and edging particles are eliminated, variations in brightness and signal noise are retouched and agglomerated particles are separated. The main part in object detection is image binarization, whereby every image pixel is assigned to a particle (black) or the background (white) using a threshold. The recognition of objects (particles) and feature attribution is realized by the software. In the last step, the classification, the particles are arranged in classes (e.g. size equivalent classes) on the basis of their attributed features (size and shape parameters).

Numerous size and shape parameters can be determined from the particles images by the appropriate software. Important size parameters are for example (CE) equivalent disc diameter Deq, maximum inscribed disc diameter Din, fiber length XLG (geodesic length) and fiber diameter XFD.

The equivalent disc diameter corresponds to the disc diameter of identical area to 2-D-projected particles, which is often used as size indicator for irregular shaped particles in process technology. On the contrary the maximum inscribed disc diameter of the 2-D-projected particle corresponds more or less to the sieve diameter. The geodesic length and the fiber diameter are suited very well for the characterization of fibers.

There are numerous and very application-specific shape parameters. The aim is to get extra morphological parameters in addition to particle size, whereby the particle characteristics can be better or basically described. Examples are “aspect ratio AD”, the ratio of length to width of the particles, “circularity ZK”, an indicator for particle deviation from the ideal circle and “concavity index C”, which reflects the ratio of area difference of convex envelope and area of the particle to convex envelope. Another important shape parameter is “perimeter”, which displays the particle coverage.
