Gyratory Screener Knowledge Training for New Employees

Yesterday, Our international department manager led new employees into the workshop for product knowledge training.

In order to facilitate new employees fully understand the enterprise culture, promote teamwork ability, enhance personal qualities, understand the product knowledge, more sufficiently resolve customers’ questions occurring in the process of selective purchasing products and to create a good atmosphere for further work. Our company arranges training courses on a regular basis leading the staff into workshop personally. The target learning object is the gyratory vibrating screen which is putting into production in the workshop.

The manager introduced with profound theories in simple language about the main components of the gyratory screen, operating principle, details need to attention and the it’s advantages such as the bouncing balls’ installation for self-cleaning to keep the mesh screen efficiency for a long time. Managers answered various questions put forward by the new employee. Through the training, we not only have a deeper understanding of our company, but get more confidence in corporate outlooks and personal career development.

Welcome to visit our workshop to get to know more about out products. If you want view more, please click here:www.pkmanufacture.com

Strict Inspection—Provide Perfect Equipment for Clients(Ⅰ)

After the circular vibrating screen production was completed,and there is an important step before delivery goods,that’s test running,and judge the equipment whether can work normally through equipment running condition,please see following test items:
1.Measuring rotary speed of principal shaft
The test principle is through infrared sensor scanning a fixed point on the shaft to confirm the rotary speed.Firstly,pasting the measured speed tags on rotor surface.then running the equipment,after the normal running，let the tachometer probe aims at one point on the tag movement locus,record the data,and it requires multiple measurements to take average.
2.Noise test of equipment running.
A good equipment should work without abnormal sound,after the equipment running normally,place the noise meter probe near the running parts of vibrating screen,record the data, it requires multiple measurements to take average.

Reasons lead to circular vibrating screen mesh plug

When circular vibrating screen works, the material properties are very different, as well as its shape. Due to different shape of material ,it can produce a various forms of mesh plug.After the analysis of PK machinery engineers, the cause of mesh plug mainly shown as follows:
1.Contains a lot of close to the separation point particles
2. The material moisture content is higher
3. The spherical particles or material has multi-contact points property to mesh 
4. Static electricity occurs
5. Material is a fibrous material
6. Flake shape material proportion is more
7. Woven mesh wire diameter is too thick
8.Thick Sieve mesh, unreasonable hole shape design, which will lead particles get stuck.

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. 

Do not Ignore the Unbalance Motor Vibration Phenomenon of Vibration Table!

Vibration motor is not as what you imagine, only plus a few springs on the equipment, and put on a few motors, it will become a veritable vibration equipment, then will be used for vibration production? In fact, sometimes the question is much more serious than the imagination, the theory and practice is the only way which can reach truth. Next Henan Pingyuan Mining Machinery Co., Ltd will explain to you: The unbalance vibration phenomenon of the vibration motor for vibration table.

The problem of vibration which cannot meet the vibration motor in the running of the equipment, also can never be solved, that is uneven and unbalance of the vibration. The influence of the unbalanced vibration in the screening equipment is less, while the influence will often appear in making the vibration table. However in the reality, the unbalanced force of vibration equipment is often neglected by us.
1. In the use of a single vibration motor on the vibration table, it can appear the problem of motor rotation, the material will move on the surface of vibration table.
2. In the use two vibrating motors, it will change the uniform vibration point of the vibration table. Due to counter rotation of two motors , it will offset the power in the middle of the vibration table. If the vibration amplitude around the platform is 5mm, the vibration amplitude in the center of the table can't be over 3mm.
