This grinder is ideal for reducing medium to soft materials such as grass, pellets, compressed fibers, straw, peat, husks, feedstuffs, spices, hops, wood, tobacco, paper, soft ore etc.
The grinder comes with 3 adjustable knives which can be re-sharpened when needed and easy to remove screens are available in various sizes to satisfy any mesh requirements.
It has a heavy-duty construction and maintenance-free design and sample container is simple to remove and replace. The unit is equipped with a 2Hp, 3 phase, motor. Manual on/off switch and overload protection is included.
This grinder is ideal for grinding soil, clay, earth material, soft coal, etc with a dual stage feeding hopper designed to eliminate dust from escaping.
Grinding chamber dimensions are 132mm diameter x 76mm deep with a grinding capacity between 20-200g. The unit is equipped with a 1Hp 3 phase motor with manual on/off switch
The Swing Hammer Mill is possibly the most economical mill available for the return in output. Glen Creston offers two versions of the mill – Blower Discharge and Bottom Discharge – each available in three sizes and with 2 mounting options.
The bottom discharge is for discharge of material by gravity and the blower discharge is where a powerful fan pulls the material into the grinding chamber and through the screen which is suitable for lighter weight particles, such as paper, plastic foam or feathers and for applications where the processed material is distributed to another processing area or level.
The chart lists the approximate throughput per hour from the Hammer Mill 10. The results will depend on screen size, material, moisture content, feeding method and motor power. Results may be approximately doubled for Model 20 and tripled for Model 30.

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.
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.
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.
The chart lists the grinding performance for the Gyro Mill using a 100 cc tungsten carbide grinding dish, with grinding intensity set at “high”.

The UDY Cyclone Sample Mill is designed for rapid grinding of a wide variety of soft to medium-hard materials. It is extensively used in milling grains, feeds, forages, leaves and similar materials prior to near-infrared reflectance (NIR) measurement or chemical analysis. Other applications include small to medium volume milling of; pharmaceuticals, detergents, fertilizers, plastics, coal, wood chips and friable materials.
UDY Cyclone Sample Mills use a patented method of grinding. High-speed rotation of the impeller and air currents throw particles into, and rolls them around the grinding ring. Particles remain in the grinding chamber until impact shattering and abrasion make them small enough to flow out the exit with the air current. The airflow removes essentially all material and makes clean out unnecessary. The airflow also minimises heating and therefore eliminates thermal degradation.
The maximum initial particle size depends on the mass and grinding properties of the material. The standard Mill Cover limits the maximum initial particle dimension to 5 mm. Low mass materials such as forages, leaves, and wood chips can be introduced in larger initial sizes by using the optional Forage Cover without preliminary grinding.
The screen covering the air/sample outlet affects the particle size two ways. The screen limits the maximum particle size which can be thrown out by impact with the impeller. Screens with smaller holes also reduce the airflow and, consequently, the size of particles exiting with the airflow. A screen with 1.0 mm openings is generally recommended, but screens with 2.0, 0.8, 0.5, 0.4 and 0.25 mm openings are also available.
The UDY Cyclone Sample Mill is designed for long life. The parts subject to wear are all replaceable. The frequency of replacement depends on the abrasiveness of the material. Guidance for selection of spare parts based on the number and types of samples is available.
