Laboratory mills, or laboratory mill grinders, utilize mechanical force to pulverize non-homogenous, batch samples into smaller, representative, homogenous samples for analytical and quality control testing. Mills are composed of a grinding element, such as a beater or cutting blade, housed within a stainless steel or disposable plastic milling chamber. The grinding element is connected to a high-speed motor regulated by a timer or digital controller.
What are Laboratory Mills Used For?
Lab grinding mills are designed to accommodate a variety of grinding elements for samples with different physical properties: dry, elastic, wet, hard, brittle and fibrous.
Impact millsare optimal for grinding hard, brittle or dried feed materials, such as grain, barley, cellulose, pharmaceuticals, resins and seeds.
Cutting millsare optimal for grinding elastic, fibrous, and soft feed materials, such as spices, hops, paper, plastics, and roots. Jaw crushers utilize a fixed and movable jaw for high-pressure crushing of glass and coal.

A - Laboratory Mill Feed Sample Hardness
（返回图表）
The Mohs Hardness Scale charts the relative hardness, or scratch resistance, of various materials from 1 (softest) to 10 (hardest). The hardness test is typically performed by pressing a loaded indenter object onto the surface of the test material to measure the size of the lasting impression. Examples of 5-Mohs materials include bone, iron, enamel, glass and titanium. Common 6-Mohs materials include steel, silica, porcelain, and zirconium.
B - Feed Grain Sample Diameter

The particle size, or grain diameter, of the sample material governs the selection of the appropriate laboratory mill.

C - Maximum Laboratory Mill Speed

The maximum grinding speed, stated in revolutions per minute (RPM), defines the optimal sample types for each mill.
IKA’s MF10models have a speed range of 3,000 to 6,500 rpm, designed for pharmacy samples, like vitamins, tablets, and roots, as well as rubbers and plastics.
IKA M20 models maintain a fixed speed of 20,000 rpm for pulverizing grain, seeds, ceramics, salt and active carbon.
IKA Tube Millsfeature a speed range of 5,000 to 25,000 rpm, crushes stems, leaves, tobacco, ginger, flowers, drug capsules and enzyme powder.
IKA A11 models固定速度为28,000rpm，用于磨削纤维素，树脂，动物饲料，香料，煤和洗涤剂。
D - Laboratory Mill Cooling Method

Effective sample preparation prior to milling ensures maximal grinding efficiency and mitigates instrument wear-and-tear. Elastic or fibrous samples, such as rubber and plant materials, are frozen over dry ice prior to grinding. Biological samples, such as nucleic acids and proteins, are cryogenically frozen in liquid nitrogen before milling. To prevent damage to the unit, wet samples are passively cooled and dried before milling to prevent adhesion to grinding elements.
E - Laboratory Mill Volume
Low-throughput models are designed to accommodate sample volumes down to 40 ml while high-throughput models process samples up to 250 ml in volume.
