How to Install the Circular Vibrating Screen Punching Mesh?

Screen meshes Includes manganese steel woven mesh screen, perforated plate, stainless steel sieve, etc., each of which has its own special place, and therefore it should be selected according to the actual situation.Here we will share some of the easy to implement tips to install the circular vibrating screen punching mesh.
Vibrating mesh sieve punching method of installation with slime mesh sieve dehydration installation is similar. Entire slime dewatering screen is horizontal assembled, but in order to ensure the dehydration effect of the machine, so the screen is negatively corner installation. Alternatively polyurethane screen mesh, tension mounted, or stainless steel weld seam sieve, pressing installation, to meet different needs. But the circular vibrating screen is angled, when using perforated screen, pressing need for the use of square wood, wedge tensioning way.

Insufficient tightness of the screen will cause the following effects:
① mesh bending deformation, stress concentration serious, relaxation is easy to produce secondary vibration sieve, sieve premature breakage under alternating stress, caused no small economic loss;
② bending deformation affecting mesh sieve through effective screening area, so this should be through the sieve through the sieve material failed, resulting in reduced screening efficiency;
③ screen surface depressions lead to material retention, hinder the forward movement of the material layer, and ultimately affect the productivity of the shaker.

In view of this, increasing the tension of the screen, to ensure smooth screen surface, not only can effectively improve screen life, but also help to ensure the efficiency and productivity of vibrating sieve.

Dewatering Screen in the Application of Potash Feldspar Ore Dressing Process

 Dewatering Screen in the Application of Potash Feldspar Ore Dressing Process

At present most of the production of potassium feldspar manufacturers in product dehydration link with spiral classifier and filter press to dewatering process, but the spiral classifier separation material, low working efficiency, filter press investment in energy consumption. And in the production of non-metallic mineral potassium feldspar, if through the spiral separator slag water separation, separation after finished product moisture content is exorbitant, can't do the heap.

Why do we choose to use dewatering screen? This is because that dewatering screen not only can be used for ball mill ore grading but can be used in potassium feldspar product dehydration. Potassium feldspar product dehydration link in traditional production process is processed by filter press, the disadvantage is that investment in energy consumption and low working efficiency, dehydration after finished the actual water content is high. Dewatering screen in the application of potash feldspar ore dressing greatly improve the production efficiency, reduce the energy consumption, reduce the area.

How to Distinguish Between the Shaft and Shaftless Drum Screen?

How to Distinguish Between the Shaft and Shaftless Drum Screen?

The drum screen can be divided into two structures,shaft drum screen and shaftless drum screen.The common point of them is that they can both use for the bulk materials.But for some relatively complex material properties,we should choose the suitable drum screen according to the working condition.Here PK Machinery will give you a better understanding about it.Hope the following passage will help you.
Difference:
1.Methods of Installation 
The roller device of the shaft drum screen is arranged on the frame. 
The screen of the shaftless drum screen is installed horizontally
2.Working Principle
For the shaft drum screen,after the drum motor reducer are connected together by coupling means, the drive roller means rotatable about its axis. When the material into the drum unit, due to the tilt and rotation of the drum unit, so that the material flip and scroll the screen surface, so that qualified materials through the discharge port at the bottom of the rear end of the drum is discharged, substandard materials (sieve product) by the end of discharge rollers discharge port. As the material within the drum flip, roll, so that the card material in the meshes can be ejected, to prevent clogging of the sieve.

For the shaftless drum screen,the motor drive pulley or sprocket gear roller, usually the slower speed, roller length can be longer, so that the material fully screened. Internal drum lifting plate may cause the material moves forward on the discharge end of the drum sieve material, sieve material discharge hopper along the drum income.
3.Application
Shaft drum screen generally used in a large proportion of granular materials, such as: sand, coal, limestone, fertilizer, compost, ore.
Shaftless drum screen always used in smaller proportion of materials, such as: garbage, wood, charcoal, compost, building materials, chemical products etc.

Dewatering Screen for coal industry

Dewatering screens have a wide variety of application including dewatering, desliming, degritting, rinsing, scrubbing and washing. It is made up of screen cloth, vibration exciter, supporting system and motor. Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials which can be processed through a dewatering screen.


Working principle:
      To dewater material effectively, damp material is feed onto a steep, downward inclined screen surface at the feed end of the Dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface. Counter rotating motors create a linear motion, driving solids uphill, while liquid drains through the screen media. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings.
      When the two vibrating motor that installed vertically on the coal dewatering screen rotate relatively, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration.

Features:
   1. Low noise, easy to maintain
   2. Large capacity
   3. High screening efficiency
   4. Light weight, easy to disassemble and replace
   5. Stable structure and strong exciting force
Advantage:

   1.Stable structure with strong exciting force
   2.High screening efficiency and low noise pollution created
   3.Durable and easy maintenance
   4.Materials that stuck at the screening mesh can easily remove
   5.Low energy consumption
   6.Large handling capacity.
   7.Light weight, easy to disassemble and replace

Application:
Dewatering screen is widely used in coal industry, ore industry, electricity industry metallurgy industry, mining industry etc.
