In today's pursuit of high-efficiency screening, when faced with the classic capacity requirement of "how many tons per hour," there are often multiple options. However, if your material is fragile, prone to agglomeration, requires high-precision grading, or needs gentle screening, the circular gyratory screen (also known as a circular rotary screen) stands out from other vibrating screens as a superior solution.
Revolutionizing Traditional Vibration: Simulating the "Gentle Art" of Manual Screening. Unlike vibrating screens that rely on strong vertical impact, the core motion of the circular gyratory screen is a smooth, three-dimensional gyratory rotation. It mimics efficient manual screening—the screen body makes a uniform circular motion in the horizontal plane, accompanied by slight up-and-down undulations. This motion mode brings two revolutionary advantages:
1. Extremely low material breakage rate: The material is gradually diffused and conveyed on the screen in a spiral pattern, avoiding violent impacts and friction, making it extremely friendly to brittle materials such as crystalline, granular foods, and chemical intermediates.
2. Near-perfect anti-clogging capability: The gentle and continuous rotational force allows materials to tumble and disperse fully, maximizing the chance for fine particles to pass through the mesh. Simultaneously, it effectively breaks up electrostatic agglomerations, significantly reducing the risk of screen clogging and ensuring continuous production.
Having clarified the advantages of the circular gyratory screen, how do you specifically select a model to achieve optimal screening results? This guide will provide a practical overview of model selection, key configurations, and layout planning.
I. Core Model Recommendations and Parameter Matching: Mainstream circular gyratory screen models are concentrated between 1500mm and 2600mm in screen diameter. While ensuring throughput, they can perform precise grading of 2-5 particle sizes. Key parameters: screening area, motor power, number of screen layers, and operating noise.
II. Key Configuration Selection: Details that determine performance include screen material, screen cleaning device (anti-clogging guarantee), and sealing and dust prevention.
III. Equipment Layout and Production Planning, Space Requirements: Sufficient floor space and a minimum clearance of 2.2m (including the upper feed inlet and lower discharge outlet height) are required. Process Integration: It is recommended to use a "buffer hopper + feeder (such as screw or vibrating feeder)" method for uniform feeding to avoid instantaneous impact loads, which is key to stable output. The discharge outlet can be connected to a ton bag machine, packaging machine, or the hopper of the next process.
IV. Investment and Operating Cost Estimation, Equipment Investment: One high-quality domestic circular vibrating screen that meets the required output; the price depends on the configuration and brand. Operating Costs: Electricity consumption and maintenance; the main wear parts are the screen mesh and bouncing balls, which are easy to replace and have low cost. The equipment has no severe vibration, and the bearings and other mechanical parts have a long service life. Return on Investment (ROI): Improved screening accuracy directly reduces product waste and rework; low breakage rate ensures high product value; anti-clogging screen characteristics reduce downtime for cleaning and improve overall production efficiency.

To achieve stable production capacity and ideal output, we welcome your material samples for detailed technical discussions and on-site trial runs. During the trial, we will focus on observing the screening effect and capacity under continuous and uniform feeding, as well as whether the screen operates smoothly without clogging. A configuration validated through practical experience is the most suitable solution for you. Choosing a circular gyratory screen is not just choosing a piece of equipment, but also choosing a smarter, more precise, and more material-friendly screening philosophy.
