High-frequency vibrating screens are used to separate feeds containing solid and crushed ores down to approximately 200μm in size, and are applicable to both perfectly wet and dry grain. 

Working principle:
The frequency of the screen is controlled by an electromagnetic vibrator which is mounted beside or directly connected to the screening surface.

 Scourer eliminates the dust, the arista and beards from the kernels furthermore, it crumbles insects and detaches empty kernels and lumps of mud.

Working principle:

An intensive friction and rubbing action between the kernels, the cover and the paddle type beaters will reduce the bacterial potential in the flour.

A destoner is a machine that removes stones and clods from grain material so that they are free from grain.

Working principle:
They remove stone using a series of webs (2~5 webs). Under the bump function, the grain stay on the web and move down along the web, while the clay move reverse direction and fall into a trench.

Dampener:  To produce refined (white) wheat flour, grain is usually tempered, i.e. moisture added to the grain, before milling, to optimize milling efficiency. 

Working priciple:

It  softens the starchy "endosperm" portion of the wheat kernel, the addition of moisture also toughens the bran and ultimately reduces the energy input required to shatter the kernel, while at the same time avoiding the shattering of bran and germ particles to be separated out in this milling process by sieving or sifting.

Mill:  A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. 

High plansifter: Corn and grains are processed into grits or flour and the mixing material with big and small granules can be screened by the high square plansifter.
The multilayer sieve surface constitutes certain sieve road, so the square plansifter can screen big, medium and small grits and separate grain flour. It can also screen other grain material.

Purifier: the machine is applied in the purification and grading of semolina and fine semolina in common wheat, durum wheat and corn (maize) mills.
