The principle of AY series vibratory screening machine

We use AAREAL vertical vibratory motor, and the horizontal, vertical, inclined three-time vibration generated by the motor, then this vibration transmitted to the screen surface. Change the space phase angle of motor’s eccentric weights up and down, resulting in different exciting force to change the direction of movement of materials. The following statements are the general characteristics of changing the space phase angle of motor’s eccentric weights up and down:

Based on customer's actual working condition, AAREAL vibratory screening machines can be added the different roles of the auxiliary facilities, to change direction or movement of materials or sieving rate, living up to customers’ the purpose of screening.

Standard vibratory screening machines
It’s the standard models of our company, used in the screening and filtering of general materials.
Rough vibratory screening machines
It’s used in separating super-size particles from the materials easy going through the screen, suitable for 2-30 screen mesh, with high productivity. Compared with the lined vibratory screening machines, screening in 20-30 screen mesh has more advantage. It occupied more space than that of lined vibratory screening machines.
Delicate vibratory screening machines
It’s used for raising the precision of sieving. Compared with AY series standardized screening machines, it can improve the precision of screening by 1%-8%. Sifting the useful products out, can improve the added value of the products and increase enterprise's profit.
Filtering vibratory screening machines
It’s used in impurity of firm materials and separation of firm liquid. The life-span of screen mesh is long ,and it’s hard to make the mesh plug and easy to operate.
Food-grade vibratory screening machines
It meets hygienic requirements of food processing, and surfaces in contact with product is stainless steel 304, the internal structure does not have dead corners, in case the assembly and pollution of supplies.
Aero-seal vibratory screening machines
It’s used in the screening of materials necessary to add nitrogen protection, and is professional vibratory screening machine designed for powder metallurgy industry.
Mobile vibratory screening machines
Adding casters to small vibratory screening machine to move easily.
Explosion-proof vibratory screening machines
It’s the AY series vibratory screening machines with explosion-proof motor, used in the explosion-proof circumstances.
Water-spraying vibratory screening machines
Adding sprinkler pipes to AY series vibratory screening machines for the cleaning of screen timely and preventing the mesh plug, prolonging the life-span of screen mesh.
Vibratory screening machines with edges
It makes improvement on the basis of AY series vibratory screening machines, easy to observe or put in supplies.
Anti-corrosion vibratory screening machines
It is designed on the basis of the chemical properties of materials, to ensure the screening of corrosive chemicals, and the surface in contact with chemicals can be stainless steel 316L,or non-metallic materials.
