The application of vibration source of vibrating screen

The application of vibration source of rotary vibrating screen / linear vibrating screen 

Notices:

1.When the excitation power and electricity are no more than specified numerical value, it can be operated at the largest exciting force. 

2.No operating without protective cover. 

3.There is a specially-made putty in the terminal junction box. It can be took out when maintenance and got back after maintaining. 

4.It should check the following items when operating: 
     A .Whether there is enough lubricating grease in the bearing; 
     B .Whether the installation of vibration motor and fastener are firm; 
     C .Whether the link of power cable is normal; 
     D .Whether the operation is normal. 

5.We need to pay much attention to the operation of vibration motor during working. If it appears the phenomenon of overheating and oil leakage, we must stop the machine to inspect at once. 

6.After first use or suspending long time, if using the vibration motor once again, we should measure the insulation resistance of coil to ensure its numerical value is more than 20MΩ.

Vertical Type Tensioning Device of Belt Conveyor

Vertical type tensioning device is installed between the driving pulley and tail wheel, it should be closed to the minimum belt tension place (driving pulley).When the rubber belt conveyor runs, the structure drives the conveyor belt passing by 90 degree turnabout pulley, then passing by the 180 degree turnabout pulley, tensioning the rubber belt through the heavy hammer which is hanging on the frame. The effective tensioning travel is same with vehicle type tensioning device.
Vertical type tensioning device of belt conveyor
Vertical type tensioning device is suitable for the situation that is difficult to adopt vehicle type tensioning device. The advantage is that it utilizes the space of belt conveyor length which is easy to arrange. The defect is that if adopts this type of tensioning device, the turnabout pulley quantity will increase, material will be easily to fall into the place between rubber belt and pulley, which speeds the abrasion of rubber belt and pulley surface . Especially when transporting materials is damp or with larger viscosity ,the abrasion phenomenon will be more serious.

Structure and Features of Circular Vibrating Screen

Circular vibrating screen mainly consists of screen box, screen mesh, vibrator, damping spring mechanism, chassis, etc. Adopting cylinder postures eccentric shaft vibrator and eccentric block to adjust the amplitude, vibrator is installed on the screen box side plate, and rotation of belt drove by the motor, which generates centrifugal force and forces vibration of sieve box. Screening machine's side panel is made of high qualified steel plate, there is high strength bolt or ring groove rivet used for connection of side panel, beams and vibration. Vibrator is installed on the screen box side plate, driven by motor through coupling spin, along with all the produce centrifugal force to make the screen vibrate.


 Features of circular vibrating screen are as follows.
1, using eccentric block as exciting force, and the force is strong.
2, there is high strength bolt connection between beam and box of screen without welding.
3, simple structure, easy to maintain.
4, using tire coupling with flexible connection and reliable operation.
5, small amplitude, high efficiency, large dip angle structure, long service life, large capacity, low electricity consumption and low noise.

Screw Conveyor Ordered by Singapore Client was Delivered to Qingdao Port

On 2nd July,2015,screw conveyor ordered by Singapore client was ready to delivered to Qingdao port, the screw conveyor is used for conveying industrial scrap iron powder, before leaving factory, the client came to our factory and inspect the machine ,he was quite satisfied with our products and he also hoped to continue cooperating with our company.

PK Machinery manufactures two kinds of screw conveyors: pipe type and trough type. Both of them are widely used for chemical, metallurgy, paper making, and construction industries. The equipment is suitable for field flowing work, such as concrete mixing station, bulk material transit storage and etc.

In addition, PK machinery supplies belt conveyorbucket elevatorvibrating screen etc. for several years. With abundant engineering design experience, professional technical ability and strict fabricating specification, PK machinery wins the highly praise from clients all over the world, any inquiry, please feel free to contact us!
