Product Introduction
The XZS series rotary vibration screening and filtering machine is a special type, high-precision, fine-grained screening equipment designed by our factory based on absorbing domestic and foreign technologies, with international level. Fully enclosed, no dust spillage, and capable of continuous operation; High screening accuracy, high efficiency, and high screen utilization rate; Small size, light weight, quick start-up, low noise; Easy operation, convenient maintenance, and long lifespan of the screen mesh; The advantages include the ability to freely change the direction of the discharge port along the circumferential direction.
Special note: Material selection is based on the characteristics of the material and the difference in corrosion resistance. This equipment uses 304 material as the contact material. Due to the special nature of the material, explosion-proof motors are used to increase the safety of the equipment
Working principle and structural characteristics
The XZS series rotary vibrating screen uses a vibration motor to rotate and generate excitation force, causing the screen body to produce compound rotary vibration. Its motion trajectory is a complex spatial three-dimensional curve. Adjusting the space and position angle of the upper and lower heavy hammers can effectively change the trajectory of the material, extend or shorten the residence time of the material on the screen surface, and achieve the ideal screening effect
Performance characteristics
The XZS rotary vibrating screen is a new type of screening equipment, which has the following significant characteristics compared to other screening equipment.
1. The mesh screen is equipped with elastic material screening balls, which can effectively eliminate mesh blockage and achieve high screening efficiency.
2. The mesh tension is reasonable, easy to replace, and only takes 5 minutes.
3. Fully enclosed structure, no dust spillage.
4. Easy to operate, easy to clean, and can be directly used on ordinary cement floors.
This machine is widely used for screening fine powder, micro powder, ultrafine powder, as well as rod materials and dry/wet materials.

install and adjust
install
The equipment should have a stable foundation. When the equipment is installed on a general ground or cement foundation, anchor bolts may not be required. When the equipment is installed on the steel structure platform, it should be fastened to the steel structure body with bolts, and the steel structure platform should have a certain degree of rigidity;
This machine only requires one three-phase knife switch. Use a snake skin tube to thread the wire and connect the motor to the power supply. Note that the electrical control panel should be hung and installed on the wall;
The screen mesh is installed before leaving the factory, and can be replaced by oneself during use.
debugging
Before starting up, check the tightness of each clamping bolt, whether the position of each feeding port is aligned with the feeder, and observe whether the vibration motor can rotate normally and whether the spring force is obstructed. Check whether each layer of screen mesh is tightened;
Before connecting the rotary vibration screening filter to the electrical control panel, the electrical control panel should be checked first. Observe whether the operation is normal and whether there is any abnormal noise after the line is connected;
Adjust the phase angle of the upper and lower eccentric blocks to adapt to various material screening situations. The recommended basic angle range is as follows:
A. For rough grading and easy screening of large quantities of materials, the phase angle is generally selected between 0 ° and 30 °;
B. For general screening operations, the phase angle is between 30 ° and 50 °;
C. For raw materials with high precision screening, differentiation, and condensation forces, as well as materials with high moisture content that are difficult to screen, the phase angle should be selected between 45 ° and 85 °;
D. Exclude foreign objects from the raw materials and select a phase angle of 50 ° to 90 ° for wet classification;
E. For various materials, the phase angle should be carefully adjusted, and at the same time, the addition or removal of counterweights should be supplemented to achieve the appropriate excitation force and obtain the best screening state. This work must be taken seriously as it directly affects the quality of the rotary vibration screening and filtering machine.
use and maintenance
The two bearings inside the vibrating screen machine need lubrication. The outer bearing pressure cover of the bearing chamber has an oil inlet hole and is equipped with an oil inlet nozzle. Lubricating grease is added to the bearing chamber through the oil nozzle with an oil gun. Fill the bearing chamber with 3S composite calcium based grease, but not too much. The amount of grease should not exceed 1/3-2/3 of the bearing chamber volume. The high temperature of the bearing must not exceed 75 ℃.
Regularly inspect the screened products, and replace the mesh in a timely manner if the screened particles exceed the size limit;
The vibration motor should be maintained every six months. If it operates continuously for three months, lubricating grease should be added once. The lubricating grease should be 3S composite calcium based grease or molybdenum disulfide heat-resistant grease; The vibration exciter bearing has accumulated 10000 hours of operation and should be replaced.
