Lab Mills

Sample preparation is key for correct analysis results, and the type of sample preparation depends on the requirements in the analysis to be made. For this reason it is important to select the correct preparation for the analysis in question. 爱游戏平台注册登录 offers two types of Laboratory Mills, the hammer type mill and the disc type mill.

Features and Benefits

• Falling Number and Gluten Index - Officially approved mills for Falling Number and Gluten Index sample preparation.
• High sample homogeneity - Improves repeatability and accuracy of analytical results.
• Robust design - Excellent durability and very low cost of ownership.
• Suitable for grains, oilseeds and more - Flexible mills for grinding of many different sample types.

Technology

• Hammer mills - The hammer mills grind by means of a high-speed rotating steel "hammer" and has a sieve in the periphery through which the sample leaves the grinding chamber. By selecting different sieves, the particle size distribution in the sample can be varied. The hammer mill is typically used to produce a fine and homogeneous sample. The Perten Instruments hammer mills can grind up to 300-gram samples which is the requested amount in for example the Falling Number test. Because of the heat development in the grinding operation and the high air flow through the grinding chamber this type of mill is not suited for grain moisture determination.
• Disc mills - The disc mills grind the sample between one stationary and one rotating metal disc with teeth. The main application for the disc mills is grain moisture determination thanks to the possibility to grind grain without moisture loss. The particle size from the mill can be varied by adjusting the distance between the stationary and the rotating disc. There are also different disc types to choose from.
