There are five models to choose from as follows

SpectroMill ®

The SpectroMill® is a Ball Pestle Impact Grinder which reduces a millimetre sized particle sample feed to fine micrometer sizes (below 44 µm) within 5 to 30 minutes.

SpectroMill-I has a single clamping mechanism that can accommodate one sample holder or one Multi-Vial Adapter, while SpectroMill-II has two such clamping mechanisms.

Depending on its size each vial accepts sample capacities of 1 cm³ to 30 cm³ and is available in the following materials:

• Clear polystyrene
• Hardened stainless steel
• Rust resistant stainless steel
• Titanium carbide (similar Rockwell “C” hardness as tungsten carbide)

Ball pestles are offered in compatible materials to the vials. Multi-Vial Adapters with 1, 3 or 5 cavities enable processing up to 5 samples simultaneously. They are available with different bore diameters to accommodate a variety of vials.

GyralGrinder®

The GyralGrinder® is a vibratory disc mill which utilises a puk and grinding discs made of hardened steel, tungsten carbide or zirconia. Within 1 to 10 minutes, mm and sub-mm sized particles are reduced to below 44 µm. The operator can choose between 10 intensities of impact.

Glen Creston Cross Beater Mill

The popular Cross Beater Mill is used for crushing and grinding a wide assortment of materials up to the medium-hard range such as soil, bricks, concrete, rock, cement clinker, coal, glass, ores, minerals, rare earth products, chemicals, spices and grain. Applications abound within a variety of industries, including construction, environmental, mineral, chemical, agricultural and ceramic.

The mill is remarkable for combining small size with strength and power for heavy duty application and continuous operation. It processes samples from 200 g/hr up to a maximum of about 50 kg/hr, with an initial lump size of up to 30 mm down to a finest end particle size of approximately 50 microns. Coarse, medium or fine grinding can be selected. Interchangeable screens, with different hole diameters determine the fine particle size. Screens are changed quickly and simply by sliding them in and out of the recess provided. The beater tips are re-adjustable to maintain performance. The mill can be stand-mounted or bolted to a bench. The Cross Beater Mill is designed to produce little or no dust and for easy cleaning.

Glen Creston Micro Hammer Cutter Mill

The Micro Hammer Cutter Mill is the ideal machine for all dry milling applications. It provides the power of a Hammer Mill and the cutting action of a Knife Mill and has the ability to pulverise samples of almost anything in seconds, including wool, cotton & rock. With its compact design the Micro Hammer Cutter Mill will fit any lab countertop and under hoods.

Features

• Variable 600-6000 rpm motor
• 0.2 up to 6.0 mm sieves

Glen Creston Gyro Mill

The Gyro Mill is the perfect choice for rapid, homogeneous and reproducible grinding of samples to analytical fineness, both wet and dry. The equipment is widely used for precision sample preparation for wet chemistry and instrumental analysis, such as XRF and AA analysis as well as for geological / mineral assay work. Materials routinely ground by this method include brick, castings, cement, ceramics, chemicals, clinker, coal, coke, concrete, ferro-alloys, fertilisers, fluxes, glass, iron, limestone, minerals, paint, pesticides, pharmaceuticals, dried plant material, ore, precious stones, rocks, metals, sand, slags, silicates, soil, steel, wood...

The Gyro Mill is particularly recommended for grinding smaller samples from 1 cc to 250 cc. Typically, the maximum initial particle size is approximately 12 mm, depending on the hardness of the material.

Advantages

• Negligible sample contamination
• Large puck and rings result in high intensity grinding with high percentage of fineness
• Accommodates the whole range of grinding dishes, of whatever manufacture, from the most fragile to the hardest
• Easily adjustable grinding intensity control with three settings
• Variable, built-in process timer
• Cam clamping device allows rapid, simple loading and unloading of dishes
• Timer switch, stop/start switch, overload relay and cover safety switches
• Sound-proof cabinet
• Maintenance-free
• Exceptionally fast grinding: most samples ground to analytical fineness in 1 to 3 minutes

Technical Data

• Motor : 0.4 kW, 230 V single-phase 50 Hz or 400 V three-phase 50 Hz
• Other voltages or frequencies can be supplied on request
• Dimensions: 64 x 64 x 107 cm (W x D x H); weight: 275kg net

Other media such as zirconia cylinders or glass balls can be supplied to order.

Glen Creston Micronizing Mill

The Micronizing Mill is the perfect choice for precision sample preparation for XRD. It rapidly reduces samples to sub-micron sizes by a unique vibratory grinding action. Each element within the grinding vessel moves with respect to its neighbour so as to produce linear contact blows and planar shearing. Materials routinely ground by this method include Carbides, Nitrides, Borides, Cement, Clays, Shale, Mica and many others.
