After determining that a square gyratory sifter is the right choice for you, the next step is to accurately select the right technology. Compared to traditional vibrating screens, square gyratory sifter have unique selection parameters. Today, we'll discuss five key parameters you must clearly understand.
Parameter 1: Screen Surface Size (Width × Length) - Determines Processing Capacity and Screening Efficiency
Width primarily determines instantaneous processing capacity. The wider the screen surface, the thinner the material layer, allowing more opportunities for screening, resulting in higher output. Length primarily determines screening accuracy and efficiency. The longer the screen surface, the longer the material residence time, resulting in more thorough screening, especially for difficult-to-screen and easily clogged materials. Dimensions are typically expressed as "width × length" (e.g., 2000mm × 3600mm). The optimal size should be determined based on both production capacity and material characteristics (such as moisture content, viscosity, and particle size). Choose a larger width for higher output, and a longer length for higher accuracy.
Parameter 2: Number of Screen Deck Layers and Inclination Angle - Determines Classification Capacity and Material Flow Rate
Number of Deck Layers: square gyratory sifter can be configured with single or double screens ranging from 1 to 10 layers, meeting diverse requirements from simple impurity removal to multi-level precision grading. The greater the number of decks, the greater the variety of product specifications that can be separated. The inclination angle: The screen deck installation angle is adjustable (usually 0-10 degrees). A larger inclination angle increases material flow rate and yield, but with a slight sacrifice in screening accuracy. A smaller inclination angle slows flow rate and provides more thorough screening. This is the key to balancing yield and accuracy.
Parameter 3: Vibration Motor and Excitation Force - Determines Power and Motion Trajectory
The vibration motor is the power source of the square gyratory sifter. It is typically equipped with two horizontal vibration motors, rotating synchronously in opposite directions, generating a linear excitation force. The excitation force directly affects the speed and tossing force of the material on the screen. The excitation force is adjustable to accommodate materials of varying specific gravities and properties. Key selection factors include ensuring that the motor power and excitation force match the screen box size and material load to avoid over-powering or over-excessive power.
Parameter 4: Screen and Tensioning System - Determines Screening Accuracy and Service Life
The screen material should be selected based on the material characteristics (stainless steel wire, manganese steel, polyurethane, etc.). Wear and corrosion resistance are key. For the tensioning system, square screens typically utilize hook-edge tensioning or bolt-tensioning. An excellent, uniform tensioning system effectively prevents screen slack, reduces material "channeling," and significantly extends screen life.
Parameter 5: Material and Sealing Structure - Determines Equipment Life and Environmental Performance
Contact component materials include carbon steel, 304 stainless steel, 316 stainless steel, etc. The selection should be based on the corrosiveness of the material and industry hygiene standards. Regarding the sealing structure, square gyratory sifter have four corners, making sealing more challenging than round screens. Checking the corner seals for tightness to prevent dust leakage is crucial for environmental protection and clean production.
