As an important equipment in the field of industrial screening, the square swing screen is favored for its unique design and efficient performance. Its appearance is a regular square structure, and the whole is composed of core components such as screen box, screen, transmission device, frame, etc. The screen box is made of high-strength materials to ensure durability; the screen can choose the appropriate material and mesh number according to different screening needs to achieve precise separation.

In terms of working principle, the square swing screen simulates the manual screening action, and drives the transmission device through the motor to make the screen surface produce three-dimensional composite movements such as horizontal rotation, projection, and vibration. After the material enters the screen surface, it is quickly dispersed and evenly distributed under the action of this complex movement. Fine particles pass through the screen smoothly, while larger particles are discharged along the screen surface to achieve efficient screening.

This equipment has many significant advantages. First, the screening accuracy is extremely high, reaching more than 95%, thanks to its unique motion trajectory, which can effectively avoid clogging of the screen holes and ensure accurate classification of fine materials; second, the processing capacity is strong. Compared with ordinary screening equipment, the screening efficiency of the square swing screen is increased by 1.5-2 times, and more materials can be processed per unit time; third, it is easy to maintain. Due to the reasonable structural design, the components are easy to disassemble and install, and the key parts are wear-resistant and durable, which reduces the maintenance cost and frequency.

The application range of the square swing screen is very wide. In the food industry, it can be used for screening and removing impurities of flour, powdered sugar, starch, etc.; in the chemical field, it is suitable for the classification of various chemical raw materials; in the pharmaceutical industry, it can meet the high-precision screening needs of pharmaceutical particles; in addition, it also plays an important role in the building materials, ore processing and other industries. With its excellent performance and wide applicability, the square swing screen has become an indispensable screening equipment in many industrial production.

As an efficient screening equipment, the square swing screen integrates mechanical transmission and kinematics in its working principle, and achieves precise screening through a unique design. The core power of the equipment comes from the motor. The rotational power output by the motor is transmitted to the exciter through the coupling. The eccentric block in the exciter rotates at high speed, generating a periodically changing centrifugal force, driving the screen box to do complex spatial motion.

The motion trajectory of the screen box of the square swing screen is the key to its efficient screening. The movement of the screen box is composed of horizontal rotation, upward projection and horizontal vibration. When the screen box performs horizontal rotation, the material spreads around on the screen surface in a spiral trajectory, fully spreads, and increases the contact area with the screen; the upward projection makes the material jump forward on the screen surface to avoid material accumulation and prevent the screen hole from being blocked; horizontal vibration helps the material pass through the screen surface quickly and improves the screening efficiency. These three movements cooperate with each other to form an efficient motion state of the material on the screen surface similar to manual screening.

During the screening process, after the material enters the screen box from the feed inlet, the material with a particle size smaller than the size of the screen hole quickly passes through the screen under the action of movement and becomes the undersize material; while the material with a particle size larger than the size of the screen hole continues to move on the screen surface and is finally discharged from the end of the screen surface and becomes the oversize material. By adjusting the eccentric block weight and angle of the vibrator, as well as the inclination angle, amplitude and vibration frequency of the screen surface, the movement intensity of the screen box and the movement trajectory of the material can be changed to meet the needs of different materials, different screening accuracy and processing volume.

The multi-layer screen design of the square swing screen further expands its functions. Screens of different mesh sizes are installed from top to bottom in sequence. When the material passes through each layer of the screen, multi-level screening is achieved, and multiple products of different particle sizes are separated at one time, which greatly improves the screening efficiency and production capacity. This scientific working principle enables the square swing screen to show a strong performance advantage in material screening operations in many industries such as chemical, food, and ore.

The square swing screen is a leader in the field of industrial screening. With its unique structural design and working principle, it has many significant characteristics and advantages and plays an important role in many industries such as chemical, food, and minerals.

In terms of screening accuracy, the square swing screen performs excellently. By simulating the motion trajectory of manual screening, the material is subjected to a compound motion of horizontal rotation, upward projection, and horizontal vibration on the screen surface. This motion mode allows the material to fully and evenly contact the screen, effectively avoiding the blockage of the screen holes, and the screening accuracy is as high as 95% or more. Whether it is processing fine chemical raw materials or grading food particles, the material particle size can be accurately controlled to ensure stable product quality.

High screening efficiency is another highlight of the square swing screen. Its processing capacity is 1.5-2 times higher than that of ordinary screening equipment. The multi-layer screen design can realize multi-level screening and separate a variety of products of different particle sizes at one time, greatly improving production efficiency. The compound motion of the screen box allows the material to spread and jump forward quickly on the screen surface, reducing the residence time of the material on the screen surface, speeding up the screening process, and meeting the needs of large-scale production.

The square swing screen is also excellent in applicability and flexibility. It can flexibly adjust the weight and angle of the eccentric block of the vibrator, as well as the inclination angle, amplitude and vibration frequency of the screen surface according to the characteristics of different materials, such as particle size, humidity, hardness, etc., so as to change the movement intensity of the screen box and the movement trajectory of the material, and adapt to the screening operation of various materials. Whether it is dealing with sticky materials or fragile materials, suitable operating parameters can be found to ensure the screening effect.

The square swing screen also has the characteristics of stable operation and easy maintenance. Its structural design is reasonable, and the key components are made of high-quality materials. It has low vibration and low noise during operation, low impact on equipment parts, and low failure rate. Daily maintenance only requires regular inspection of screen wear, component connection and fastening, and cleaning of residual materials on the screen surface. The operation is simple, which reduces the company's maintenance cost and manpower investment.

The square swing screen has outstanding advantages such as high precision, high efficiency, strong adaptability and low maintenance cost, making it an ideal choice for industrial screening, providing reliable guarantee for enterprises to improve production quality and efficiency.
