Overview of Linear Vibration Screen:

Linear vibrating screen is a common rectangular vibrating screening equipment in the screening field, belonging to a type of lightweight screening and impurity removal equipment. It is also commonly referred to as linear oscillating screen, linear screen, linear vibrating screen machine, linear impurity removal screen, and other aliases. This screening machine can be divided into two types based on material: stainless steel linear vibrating screen and carbon steel linear vibrating screen. The Detai linear vibrating screen can be divided into different types of vibrating screen machines based on the size of the screen surface, such as 520, 525, 530, 535, 540, 1020, 1025, 1030, 1035, 1040, 1050, 1220, 1230, 1235, 1240, 1250, 1530, 1540, 1550, etc. It can also be designed and produced according to user requirements for non-standard sizes or non-standard material ports.

The classification category of Detai linear vibrating screen can be designed and produced according to user requirements, with multiple different particle sizes ranging from 1-7 layers. The mesh size of the screening machine can be selected and assembled according to the user's requirements, which to some extent facilitates the classification of multiple types of materials for new and old users. The external dimensions and discharge direction of the DeTai linear vibrating screen can be designed and produced according to the user's on-site placement requirements, making the on-site use and matching of the screen machine more flexible.

Working principle of linear vibrating screen:

The linear vibrating screen is driven by dual vibration motors. When the two vibration motors rotate synchronously and in reverse, the excitation force generated by their eccentric blocks cancels each other out in the direction parallel to the motor axis, and forms a combined force in the direction perpendicular to the motor axis. Therefore, the motion trajectory of the screen machine is a straight line. The two motor shafts have an inclination angle relative to the screen surface. Under the reasonable action of excitation force and material self gravity, the material entering the equipment is thrown up and jumps forward in a linear parabolic motion on the screen surface. Through multiple layers of screens, several specifications of sieved and undersized materials are produced, which are discharged from their respective discharge ports to achieve the purpose of screening and grading.

Technical parameters of linear vibrating screen:

Main features of linear vibrating screen:

1. Mature technology, reliable quality, high screening accuracy, and large processing capacity.

2. The screening machine has a sophisticated and reasonable design, simple structure, easy installation, low energy consumption, and low noise.

3. Reasonable design of the screen extends its service life, making it easy and fast to replace. It is suitable for use with screens made of galvanized, stainless steel, manganese steel, punched plates, and other materials.

4. The overall sealing of the screening machine is good, and there is no dust spillage.

5. Easy to maintain, suitable for automated assembly line operations.

Installation, commissioning, and usage knowledge of linear vibrating screen:

The bottom plate of the linear vibrating screen bracket should be fixed on a dedicated foundation and secured with embedded bolts. If a dedicated foundation is not built, anti vibration rubber plates should be laid between the workbench and the equipment base, and a safe and reliable grounding protection wire must be provided for the equipment before use.

be careful:After the equipment is installed in place, the device used to fix the screen body and machine base during transportation must be removed before starting up.

Precautions for installing the linear vibrating screen:

1. Check the insulation resistance of the windings of the two vibration motors to ground. If it is less than 20M Ω, it must be dried before use.

2. The springs on the upper and lower spring rings of the screen body and machine base should be completely vertically embedded in the spring rings to ensure the balance of the screen body. The vibrating part of the screen machine should 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 in reverse, and perform 10-20 minutes of idle running. If there is any abnormal sound during the operation of the equipment, it should be quickly shut down for inspection and handling. After the equipment is running normally, a small amount of material that needs to be screened can be fed into the screening machine through the feeding port. Confirm that the material is moving towards the discharge port direction, and then gradually increase to the required and tolerable feeding amount.

4. When the material is about to be fed into the feeding port, the original material should be evenly fed into the feeding port to ensure that the material on the screen surface is evenly distributed. When the material falls, there should be no excessive impact force to avoid damaging the upper screen mesh. In special cases (such as large differences in material particle size, high material density, etc.), a thicker buffer screen should be added to the feeding port as an auxiliary.

5. Users can increase or decrease the vibration force of the screening machine according to the number of layers and the specific gravity of the material (by adjusting the angle between the eccentric weights at both ends of the vibration motor to increase or decrease the vibration force), so that the screening machine can achieve the predetermined screening effect.

6. The linear vibrating screen generates an instantaneous resonance zone during shutdown, during which the amplitude and noise will significantly increase, which is a normal phenomenon. Before starting and stopping the equipment, there should be no residual material on the screen surface. The screen mesh needs to be checked regularly for tension and damage, and if there is any damage, it should be replaced immediately.

Maintenance knowledge for daily use of linear vibrating screen:

1. Pre startup inspection:

①. Check whether the screen mesh is damaged and whether the frame bolts are loose from the feeding port and observation port respectively.

②. Use both hands and eyes to check if the bolts connecting the two vibration motors to the motor board are loose.

③. Check whether the power cords of the two vibration motors are damaged or exposed.

2. Inspection during use of screening machine:

①. Check whether the vibration motor is working alone or if the polarization of another motor is damaged.

②. Check if the vibration frequency is too low or the amplitude is insufficient due to low voltage.

③. Check whether there are any improper noises or sounds in various parts of the whole machine.

3. Maintenance of the screening machine after shutdown:

①. When the screening program is finished and ready to stop, the power should be turned off after the material of the screening machine is discharged from the discharge port.

②. After the linear vibrating screen is stopped, a stop sign should be hung at the power supply.

③. After the screening machine stops steadily, promptly use a plastic filament brush to sweep away the dust on the vibration motor.

Linear vibrating screen is suitable for industries:

The Detai linear vibrating screen is widely applicable in various industries, suitable for screening various dry powder materials with particle size of 0.074-20mm, moisture content less than 70%, and no viscosity. The larger feed particle size is not greater than 20mm, and it can be used in industries such as chemical, food, plastic, pharmaceutical, metallurgical, glass, building materials, grain, fertilizer, abrasive, ceramics, etc.

Ordering instructions for linear vibrating screen:

Due to the different placement forms of linear vibrating screens in various application industries and usage sites across the country, the external dimensions and number of mesh screens assembled for each user are also different. Detai Machinery reminds users to specify material characteristics, on-site usage environment, overall dimensions of the machine, etc. when ordering, so that we can customize a screening equipment suitable for you.
