2015 Winter Games was Held at PK Machinery

Last week, for the purpose of arousing the staff’s enthusiasm effectively and enriching their lives, PK Machineryhas carried out winter games. Meanwhile, this winter games have achieved great success.

In the beginning, the leader of our PK Machinery gave a speech to present the spirit of our company and explain activity rules, after that we started games competition. This winter games include 6 items which were tug-of-war contests, rope skipping, set shot, hold the ball race, across the “river” by touching the bricks and ride a bicycle slowly. All of us were involved in the winter games and the atmosphere during the games kept warm and high all the time. In the end of the winter games, we selected the winners of each game and awarded prizes for them. Through this winter games, we became a more united and stronger team.

During our working time, we also have many activities like this. PK Machinery has done better and better to enrich our life and promote our company to develop better.

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. 

Factors affecting the efficiency of screw conveyor

Main factors influencing the efficiency of screw conveyor:

1. Material viscosity, easy caking. Material viscosity,material is prone to sticking to the blades and conveyoron the inner wall, making large resistance change in thematerial handling process, a direct impact onproductivity.

2. Spiral pipe diameter size. Under the same conditions,of large diameter conveyor transmission efficiency thandiameter small throughput and higher efficiency.

3. Angle of screw conveyor and transmission distance.

4. Material particle size, temperature, moisture,abrasion and corrosion. Specific parameter can refer to:technical parameters of screw conveyor and conveying calculation formula.

5. Screw conveyor speed. Screw conveyor speed relates to the motor of the conveyor's size. Screw conveyor speed has a close relationship with material properties. High speed screw conveyor Assembly is strict, but also better balance.

►IntroductionGyratory Screen is a new developed equipment particularly for urea .The main function is to provide accurate separation of materials without product deterioration, thereby resulting greater product yields at higher production rates. This machine consists of top cover, top screen fame, spacer, bottom screen fame, the base space and the screen box. The unique gyratory motion of the near horizontal screen surface and the available screen mesh cleaning system secure the gyratory vibrating screen quality as a high capacity product that efficiently developed for materials screening purposes.

► Application

As one of new type and high standard screening equipment, gyratory screen can be used to screen of raw materials and bean curd in large scale grease factory, and screen or classify large granular urea, powder materials or granulated feed in feed mill. Also, it can be used for preliminary cleaning of raw material in feed mill as well as classifying intermediate products after regrinding in middle-sized feed mill. What's more, gyratory screen can be widely used to screen and classify materials or finished products for grain, sodium bicarbonate, large granular urea, urea granules, ceramsite, zirconia, reduced iron powder, barite, spice, plastic, mining industry, rubber, wood industry, plywood, medicine, sugar, mining, papermaking, chemical, refractory materials, building materials, activated carbon, food, PVC powder and other fine materials etc..With the development of market circulation economy, it is increasing to be used in waste plastic industry to classify, and also can do size grading for materials with broken.

► Working principle
Gyratory screen adopts to Rotex technology,we also call it Rotex screen. which obviously improves the distribution of the material, thus it will enhance the screening efficiency and the effective utilization of the screen surface, also reduce the powder content of the final material .This design is totally enclosed without dust pollution,it not only improve the operation environment but also reduce the dynamic ratio and foundation load effectively.
