Determination of the crushing effect and applicability of hammer Cyclone Mill

The crushing effect refers to the ability of the hammer cyclone mill to process the sample into fine and uniform powder that meets the testing requirements. The core lies in breaking the sample through high-speed grinding and hammering, and then separating and collecting the powder through a sieve plate with the help of high-speed gas flow. The fineness and uniformity of the crushed material directly affect the accuracy of the subsequent detection indicators. Generally, the smaller the pore size of the sieve plate and the higher the sample pass rate, the better the crushing effect.

The applicability of the hammer cyclone mill is reflected in its matching degree with specific detection items. It is applicable to the sample preparation of indicators such as the quantity and quality of gluten, the viscosity of grains, the drop value of wheat, and the near-infrared composition. For example, when testing the gluten value of wheat, a 0.8mm sieve plate needs to achieve a 95% pass rate, corresponding to a sample particle size of 0.427mm (40 mesh /CQ16). When testing the viscosity of grains, a 0.5mm sieve plate needs to pass through 90%, with a particle size of 0.270mm (60 mesh /CQ24). However, it should be noted that this device is not suitable for determining the moisture content of samples.

The hammer cyclone mill has become a commonly used equipment for the pretreatment of grains and grain products due to its high-speed and efficient crushing capacity, low-noise design (with sound-absorbing and sound-insulating materials built into the box), automatic protection against motor overheating, and compatibility with automatic feeders (optimizing the feeding of high-moisture and shelled grains). Its technical parameters, such as 750W motor power, 16800r/min grinding hammer speed, 110mm working chamber diameter, etc., provide hardware support for stable crushing effect.
