Ash linear screen / lead concentrate linear screen

  Introduction to linear vibrating screen
The moving track of linear vibrating screen is a straight line, so it is called linear screen
The whole series has light, heavy and other specifications, with large processing capacity and high screening efficiency
The use of linear vibrating screen can be used by coal preparation, beneficiation, electric power, sugar making, salt making and other industrial departments to carry out dry and wet classification, dehydration, demineralization and desliming of medium and fine-grained materials

Structural components of linear vibrating screen:
It is mainly composed of screen box, screen frame, screen mesh, vibrating motor, motor pedestal, damping spring, support, etc

1
Screen box: it is welded by several steel plates with different thicknesses
It has certain strength and rigidity and is the main part of the screen machine

2
Screen frame: made of pine or wood with small deformation, it is mainly used to keep the screen flat and achieve normal screening

3
Screen: there are several kinds of screens, such as low carbon steel, brass, bronze, stainless steel wire, etc

4
Vibration motor: (see the operation manual of vibration motor for the use and maintenance methods)

5
Motor pedestal: when installing the vibration motor, the connecting screws must be tightened before use, especially three days before the trial use of the new screen machine, it must be tightened repeatedly to avoid accidents caused by loosening

6
Vibration damping spring: it prevents vibration from being transmitted to the ground and supports the full weight of the screen box
During installation, the spring must be perpendicular to the ground

7
Support: it is composed of four pillars and two channel steels, supporting the screen box
During installation, the pillars must be vertical to the ground, and the channel steels under the two pillars should be parallel to each other

The company has a perfect after-sales service system and sufficient supply of spare parts, which can provide users with lifelong technical services
Whether it is process design, equipment installation or replacement of vulnerable parts, there will be corresponding engineering and technical experts to provide you with high-quality services

Main features of linear vibrating screen:
1
Good sealing, very little dust spillage

2
Low energy consumption, low noise and long service life of screen

3
High screening accuracy, large processing capacity and simple structure

4
Fully enclosed structure, automatic discharge, more suitable for assembly line operation

5
All parts of the screen body are welded with rolled steel plates and profiles (some groups are connected by bolts)
The overall stiffness is good, firm and reliable

Installation, commissioning and use of linear vibrating screen: company website:   http://www

The equipment shall be fixed on a special foundation and fixed by embedded bolts
If no special foundation is laid, anti vibration rubber plates should be laid between the workbench and the equipment base
Before use, the equipment must be equipped with safe and reliable grounding protection wires
Note: after the equipment is installed in place, the device used to fix the screen body and base during transportation must be removed before starting the machine

After the new screen is installed, it should be checked according to the following requirements:
1
Check the insulation resistance of the vibration motor winding to the ground, if it is less than 20mω It can only be used after drying

2
On the upper and lower spring seats of the screen body and the base, the spring should be completely vertically embedded in the spring seat to ensure the balance of the screen body
The vibrating part of the screen machine must not have any hard connection or contact with other objects outside the machine

3
Close the power switch, confirm that the vibration motor rotates synchronously and reversely, and carry out idling for 10-20 minutes
If the equipment has abnormal sound during operation, it should be shut down quickly for inspection and treatment
After the equipment operates normally, a small amount of materials that need to be screened can be set into the screening machine through the feed port, confirm that the materials move towards the discharge port, and then gradually increase to the required and bearable feeding amount

4
When screening materials, the materials should be evenly put into the feed port to ensure that the materials on the screen surface are evenly distributed
When the material falls, there should be no big impact to avoid damaging the screen
Under special circumstances (such as large difference in particle size of the material, large proportion of the material, etc
), a layer of coarse screen should be added on the feed inlet as a buffer

5
The user can increase or decrease the exciting force of the screen machine according to the number of layers of the screen machine and the specific gravity of the material (increase or decrease the exciting force by adjusting the included angle of the eccentric weights at both ends of the vibrating motor), so that the screen machine can achieve a good screening effect

6
When the equipment is shut down, it will produce an instantaneous resonance zone
At this time, the amplitude and noise will increase significantly, which is a normal phenomenon
Before the equipment is started and shut down, there must be no residual material on the screen surface
The screen should be checked frequently for tension and damage
If there is damage, it should be replaced immediately
