laboratory sample pulverizers

These ring grinders also come in single or multiple stations or bowls.  The most common being 1 bowl but as production or sample contamination reduction might require I saw as much a 7 bowls on one machine.  The size/capacity of the bowl and its ring & puck also varies depending on how much you want to grind and pulveriser at the same time

The D. F. C. Laboratory Pulverizer is an excellent unit for reducing primary laboratory crusher or roll products to a fineness up to 120 mesh in preparation for treatment tests. This pulverizer is ideal for ore dressing, assay, chemical and industrial laboratories

The capacities of this unit will vary with different materials and conditions, but a medium quartz ore can be reduced from ¼ mesh to 100 mesh at the rate of 1.4 pounds per minute. The degree of fineness of product obtained can be easily adjusted by turning a handwheel at the rear of the machine. A lock nut holds adjustments made, thus assuring a uniform product size. Easy and thorough cleaning is permitted by a hinged cover which drops back, exposing the grinding chamber which is lined with baked enamel for additional certainty in cleaning to prevent salting of samples

Design of the D. F. C. Laboratory Pulverizer combines simplicity with the proven advantages of planetary motion which eliminates all possibility of grooving the rotating discs. This unit is driven directly without the use of a gear train. All bearings and gears run in a bath of oil

Drive may be by tight and loose pulleys for flat belt or a motor may be mounted on the pulverizer frame and equipped with an enclosed V-belt drive. Correct belt tension is secured by raising or lowering the motor base with an adjusting bolt and nut

Unlike other machines, PALLMANN GRANULATORS have TXX, TOTAL AXXESS, front and back panels that provide extended access for blade changes, clean out and maintenance WITHOUT COMPROMISING THE STRUCTURAL INTEGRITY OF THE CUTTING CHAMBER

From small beside-the-press (BTP) models to wide body granulators (up to 83” wide) for thermoforming and sheet producers, and heavy-duty recycling granulators including wet-grinding, with options like feed-rolls and auger-feed systems

the right pulverizer for reliable size reduction of any

The RETSCH pulverizer range covers applications from the preliminary size reduction of particles of several centimeters to fine grinding down to the nano range. Retsch Pulverizer Mill.A good pulverizer guarantees reproducible sample preparation, which is the basis for any reliable and accurate laboratory analysis. RETSCH products turn any laboratory sample into a representative part with required homogeneous analytical fineness.

Our comprehensive range of the most modern pulverizer mills and crushers are suitable for coarse, fine and ultra-fine size reduction of almost any material. The wide selection of grinding tools and accessories not only ensures contamination- free preparation but also adaptation to the specific requirements of such different areas of application as construction materials, metallurgy, foodstuffs, pharmaceuticals or environment. Particle size reduction of solids or bulk materials is required when the particles are too coarse or the material is too inhomogeneous for subsequent processes such as analysis, division, mixing or further processing. The standard deviation of any subsequent analysis can be minimized drastically by particle reduction and homogenization of the analysis sample.

If the initial particle size of the sample is coarse, it might be necessary to use two different pulverizer machines, one for preliminary size reduction and one for fine grinding, to achieve analytical fineness. To choose suitable grinding tools is also part of the selection process for finding the right pulverizer for your material. Here the important criteria are hardness, abrasion resistance, possible contamination and, for ball mills, the energy input.
