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.
实验室磨坊是用什么？
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.
影响磨坊are 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.
Analytical mills are commonly used for impact grinding of frozen food and vegetation.
Mortar grinders are used to pulverize dry or suspended organic samples, like homogenized pastes or creams.
Bead mills are optimal for shearing cell and tissue culture sample preparations.

MOHS硬度量表图表了从1（最柔软）到10（最硬）的各种材料的相对硬度或刮擦电阻。硬度测试通常是通过将加载的凹痕物体按在测试材料表面以测量持久印象的大小来执行的。5-MOHS材料的例子包括骨，铁，搪瓷，玻璃和钛。常见的6-MOHS材料包括钢，二氧化硅，瓷器和锆。
B-饲料谷物样品直径

The particle size, or grain diameter, of the sample material governs the selection of the appropriate laboratory mill.
IKA’s M20 modelspecializes in pulverizing small-particle samples最多7mmin diameter whileIKA的MF10系统可容纳大粒子样品最多10mmin diameter.
C-最大实验室磨机速度
(back to chart)
The maximum grinding speed, stated in revolutions per minute (RPM), defines the optimal sample types for each mill.
IKA的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型号S保持20,000 rpm的固定速度用于粉碎谷物，种子，陶瓷，盐和活性碳。
IKA管磨机sfeature a speed range of 5,000 to 25,000 rpm, crushes stems, leaves, tobacco, ginger, flowers, drug capsules and enzyme powder.
ika a11modelshave a fixed speed of 28,000 rpm to grind cellulose, resin, animal feed, spices, coal and detergents.
D -实验室轧机冷却方法
(back to chart)
在铣削之前进行有效的样品制备可确保最大的研磨效率，并降低仪器磨损。在研磨之前，将弹性或纤维样品（例如橡胶和植物材料）冷冻在干冰上。铣削之前，生物样品（例如核酸和蛋白质）在液氮中被冷冻冷冻。为了防止对单元的损坏，在铣削之前对湿样品进行被动冷却和干燥，以防止粘附磨损元件。
E - Laboratory Mill Volume
低通量模型旨在容纳40毫升的样品量，而高通量模型则处理高达250毫升体积的样品。
F - Laboratory Mill Motor Output
(back to chart)
IKA’s portfolio of laboratory millsand grinders include low-power models with 80-Watt motors and high-power models with 500-Watt motors. IKA’s standard units include protection mechanisms such as emergency-stop switches, overheating alarms, and grinding enclosures to prevent operator exposure.
