Besides the air jet sieve method used by HMK-200, sieve methods also include regular manual sieve, mechanical sieve, wet sieve, sound sieve method, panning sieve method and self-assembly sieve, etc. Among these methods, mechanical sieve is a kind of popular sieve method at present. HMKTest produces good quality and low price mechanical sieve method instruments.

Manual sieve: manual sieve is an old sieve method which cost more time. It is a necessary method to obtain reliable dry sieving data. Put the material into the sieve and add the bottom and cover. Tap the sieve frame while sieving (similar to a beating sieve in the mechanical sieve), 125~150 strikes per minute. Turn the sieve 1/8 round every 25 strikes. After sieving for 10 minutes, replace a bottom which catch the material, then sieve for more 5 minutes. Through weighing, if the amount of passing fine material per minute within the next 5 minutes is less than 0.1% of the amount of feeding, the sieving is qualified. That is to reach the sieving end point.

Mechanical sieve: This sieve saves a lot of manpower and time compared to manual sieve. Commonly used are:

Eccentric motor vibration sieve method

SIEVEA 501 vibration sieve

Electromagnetic vibration sieve method

SIEVEA 502 electromagnetic vibration sieve

Mechanical flapping and vibration sieve

SIEVEA 503 standard flapping sieve
