How to debug linear vibration sieve?

1. Linear vibrating screen generally adopts three-phase alternating current. Please ensure correct power supply connection ,no conductive material, specialized alternating current socket.
2. The base must be fixed firmly by bolt to guarantee a same height difference front and back supporting seat , the feeding end and discharge end in a horizontal plane, otherwise screening effect will not reach the requirements of qualified products.
3. Check the flatness of screen mesh, ensure screen mesh is installed on the frame correctly, keep the screen mesh in the same horizontal plane to prevent screen tilt, and screening materials not up to the ideal state.
4. Check the each component of linear vibrating screen to ensure they’re firm and reliable, all the bolts must be tightened without looseness.
5. Ensure there is 30-50mmgap between linear vibrating screen and the surrounding fixtures, and check whether screw is locked well or not.
6. Take off the transportation support before starting up the linear vibrating screen, and add the support again until the vibrating screen operation becomes normal.
7. Pay attention to observe the material trajectory after starting up, adjust the screening state according to the material screening trajectory.

The role of drum screen in the food processing industry

Drum screen produced by PK machinery is widely used in coal, mining, power industry, but nowdays it is more used in grain processing and act as an immense role.

The pore diameter is a bit larger than the biggest particles in grain purification processing, its role is to let the food particles and smaller impurities go through sieve pores and down, while the large size particles as oversized things was discharged, feed the grain into the sieve, it will move with little impurity through the pore, the large impurity like paper, hessian cloth, fag end, masonry plaster, wood and long straw as oversized things discharged, the small impurities such as dust and sand will be filtered out by the sieve on the exit.the grain is discharged with strong suction process, the major part of the drum screen is perforated screen which is the horizontal drum, outside is a brush fixed to clean the pore, beside this there is a suction equipment to removal the dust.

The drum screen is acting as a cleaning equipment before grain flow in silo, large capacity and easy conduct will increase the work processing

Installation notice of circular vibrating screen punching mesh

General screen meshes include manganese steel woven wire mesh, punching mesh and stainless steel screen plate etc. Each kind mesh should be selected according to the on-site working condition. Today we will talk about the installation of punching screen mesh.
The punching screen mesh installation method for circular vibrating screen is the same with dewatering screen.
Generally speaking, the slurry dewatering screen is horizontally installed,however, in order to guarantee the application effect, the screen mesh is installed with a negative angle. The screen mesh can be polyurethane material with tension type installation, or stainless steel bar screen mesh with compression type to meet different working conditions.

Circular vibrating screen is installed with angle, when adopt the punching screen mesh, it needs lumps of wood to press tightly, then tension with wood key . Please see the following sketch: 
If the screen mesh tension is not enough, it will bring negative influence:
1.The screen mesh is easy to bend and the screen mesh will slack and easy to revibrate. Meanwhile it will reduce the screen mesh service life. 
2.It will influence the effective screen surface, reduce the screening efficiency.
3.It will stop the material moving forward and reduce the capacity.
In this regard,in order to guarantee the smooth screen mesh , increase the service life and guarantee the capacity and screening efficiency, the tension of screen mesh must be improved.

Improve dry or wet screening efficiency of vibrating screen

Following methods can improve screening efficiency of vibrating screen:

1.For dry screening,we should strictly control the water content,for material with high water content,please consider screening with ingredients.
2.Reduce the of plugged hole,we can consider using the self-cleaning sieve plate,for example,for spring rod type screen mesh surface,we can add a prevent blockage device below the screen.
3.Improve the aperture percentage,high aperture percentage is beneficial to improve the screening effect.
4.Adjust the feeding way.Material can be fed according to the sieve surface width and ensure the sieve surface can be fully utilized.
5.If possible,please consider the dip angle of the screen machine,suitable angle is beneficial to reduce the thickness of material and achieve thin material screening.
6.For circular vibrating screen,we can consider adjusting the balance weight to improve the screening effect.
7.If possible, coarse screening before feeding material.
8.If possible, we can adopt wet screening,it’s the most effective way to improve the screening effect.
