What is the selection notice of rotary vibrating screen?

1.Size of working area: rotary vibrating screen is circular, sieve surface area will effect of screening yield, so screening efficiency and yield can be improved by increasing the screening area. So the size of the field is one of the keys to the vibration screening.
2.Material characteristics: material properties,flowability and size.
3.Construction material: because of the different sieving materials, the construction material is also different, for example: food, salt, sugar and other related food industries, the whole machine material is SUS304. One reason is that hardness,thickness and wear resistance of 304 material are better, besides, polished stainless steel is bright like a mirror, the surface is clean and health, maintenance is very convenient which do not affect the material quality after screening. If the material is chemical, metallurgical and other raw materials, you can choose Q235 material, which not only save cost but also not affect the use.
4.Screen mesh can be divided into two kinds: stainless steel and carbon steel.
The shape and size of rotary vibrating screen are different generally based on the actual application and the on-site condition, and can be designed according to the requirements of clients to meet special circumstances. Common types of rotary vibrating screen: XZS-800mm, XZS-1000mm, XZS-1200mm, XZS-1500mm, XZS-1800mm, etc. 

Rotary Vibrating Screen

Factors should be Considered when Purchase a Vibrating Screen

First, the physical properties of the material to be sieved
Including material particle size, shape, moisture content, bulk density, and other material properties. When the particle size is very small, mesh is small, usually screening rate is very low, the same amount of processing need to use a larger model; when large humidity of materials, screening efficiency will be reduced, but the larger mesh size, moisture the impact is smaller; when the material is corrosive, usually made of stainless steel or stainless steel material contact parts.
Second, the nature and structure of the screen surface
If materials do vertical movement on the screen surface, it will have high screening rate and large capacity. For certain material, production rate and screening rate of vibrating screen are determined by mesh size. In general, wide screen surface has high production rate and long screen surface has high screening rate. What’s more, the larger the effective screening area is, the higher the screening rate is.

circular vibrating screen

Third, the production conditions
When a large load screening machine, the low screening efficiency. Feeding uniformity of screening process significant, so try to achieve uniform feed (In this regard, our company specializes in plane rotary sieve inlet Added sub-feeder, can achieve uniform feed).
Only taking the above influence factors into consideration can users purchase the most economical and appropriate vibrating screen.More information, please visit www.pkmachinery.com

What is the Applicable Material for Drum Screen

Drum screen is a kind of cylinder revolving screening machinery that relies on gravity, its working principle is different with rotary vibrating sieve, linear vibrating screen, drum screen can generate strong exciting force, so if dealing with the proportion of lighter materials, it is not suitable for drum screen, the screen is easy to get blocked due to the irregular shape material, and the most important is the screening effect is bad, so what is the applicable material for drum screen?

 

Drum screen also is often used in mining, sand ,gravel industries, common screen mesh size can be larger than 5 mm, the smallest mesh size should larger than 3 mm, if the mesh size is smaller that is the wire mesh is small ,the service life will be shorter, besides, the drum screen doesn’t do a good job for on sieving fine material and the sieving efficiency is not very good.

 

Except for sandstone, drum screen is also more commonly used for granular material screening, such as: chemical fertilizer, ceramsite and so on. The sieving efficiency is good and easy to handle large-scale capacity. 

How to Maintain Vibrating Screen in Summer

In summer, excess temperature is a hidden danger of daily operation for vibrating screen, generally speaking, working requirements of the environment temperature is not more than 40 ℃, so during the daily operation of vibrating screen, what we should concern about is not only the process of production, but also the degree of temperature that the vibrating screen can bear.

For the outdoor working conditions, a anti-sunshine net or cover should be set up for the vibrating screen.

Long-time sun exposure not only make the machine easy to get aging, but also cause the vibrating screen can not work normally due to the high temperature which will affect the screening efficiency and quality, it will even lead to a serious component damage, such as the damage of vibration motor.

For the indoor working condition or vibrating screen works in an ore processing plant, please pay attention to the adjustment of the indoor temperature, as well as the ventilation and the permeability, generally, a good working temperature is not more than 40 ℃.

The Classification and Function of Rotary Vibrating Screen Sealing Ring

As we all know, rotary vibrating screen does a good job in food, chemical, ceramic, paper making, metallurgy industries, as well as its components sealing ring which plays an important role to ensure the sealing performance of rotary vibrating screen.

Generally speaking, sealing ring can be divided into two types: U type and V type, it is mainly used for screen frame, net rack and dust cover to ensure better sealing performance and prevent leakage of material, at the same time it can reduce the destructive force to screen frame that rotary vibrating screen brings in vibration.

 

Sealing ring is commonly made of rubber, silicone and polyurethane, if there is no special requirement, it will be equipped with rubber sealing ring; Silicone and polyurethane sealing rings are mainly used for materials with special properties, such as high temperature, oil, corrosive materials. Among three types of sealing rings, the silicone sealing ring has a better sealing effect.

 

vibrating screen apply to environmental or sewage treatment industry

There are many people questioning the processing capacity of vibrating screen in sewage treatment, however, we can see the vibrating screen plays an irreplaceable role in environmental industry and sewage industry as it can remove the municipal wastes, particles of heavy metals and fine particle pollutants in sewage effectively.

 

Paper-making industry:
Vibrating screen acts as a filter grid in the pre-treatment of industrial sewage which generated in paper-making industry, and effectively removed large particles of pollutants in wastewater.
Vibrating screen plays an important role in sewage treatment:
1. Sanitary sewage
With the improvement of life quality, the emission of sanitary sewage capacity is also continuously increasing. Although numerous municipal wastes are mixed in the sanitary sewage, vibrating screen has very good application in the pre-treatment of these municipal wastes. 
2. Sewage treatment plant
Sewage treatment plant disposes the sewage by passing through pre-treatment, primary and secondary treatment, advanced treatment and others. We have mentioned that it can play the main role in grid filtration in the pre-treatment process. Then we can utilize the exquisite vibrating screen to carry out fine filtration before sedimentation. This will not only shorten the settling time, but also improve the energy efficiency of the sewage treatment.
In summary, vibrating screen has obvious expression in the field of environmental protection and sewage treatment capacity and function. However, we have to understand that only the more meticulous manufacturing and improve the working efficiency of vibrating screen in all aspects, after that only we can more efficiently utilize these working performances and benefit features of vibrating screen.

Application Analysis of Calcium Carbonate Rotary Vibrating Screen

The sealing performance of calcium carbonate rotary vibrating screen is pretty good, non-blocking design and precise screening. Besides, you can also choose ultrasonic vibrating screen instead of common rotary vibrating screen in order to achieve more accurate screening performance, the screening accuracy even can reach 500 mesh.

 In the process of production of calcium carbonate, it mainly includes light calcium carbonate and heavy calcium carbonate, the production process of two kinds of calcium carbonate is the same during crushing and screening. When screening the calcium carbonate, the output rate is designed according to manufacturing production rate per hour, the screening amount is calculated as per the material amount after crushing, the general selection of material granularity is around 100 mesh and the main selection specification is 60 mesh, 80 mesh and 120 mesh etc. In addition, the mesh size is also selected according to the needs of users. In the process of screening, rotary vibrating screen is the best screening equipment, the screen mesh can be replaced with the previous required mesh size in order to achieve the screening requirements.

Structures and Features for Three types of Rotary Vibrating Screen Net Rack

Rotary vibrating screen is designed as a high-precision screening machine it is widely used for sugar, salt, wheat flour, rice flour, pigment, medicine powder, ceramic, silica sand, metallurgy zinc powder, aluminum powder, iron powder, calcium powder etc. 

The net rack is the important component of rotary vibrating screen, here we will introduce the structures and features of three common net racks for rotary vibrating screen.

1.U-shaped net rack 
It belongs to the very commonly used model of rotary vibrating screen, first use the pressurized tooling to fix the thick wire diameter of screen mesh in the U-shaped groove, this layer is called meshed net, then the working net is tiled above the meshed net and clamped it. The advantage of this type of net rack is the replacement of working net in a faster rate, the framework of meshed net supports the working net to ensure the flatness of screen surface and prevent the impulsive force of material causing damage of working net, at the same time also will avoid the damage of working net due to the strike of bouncing ball that on the screen plate. The only disadvantage of this type of net rack is the overlapping part of meshed net and working net, which will influence the screen area.
