The probability screen, also known as the Mogensen screen, is an efficient screening equipment that achieves material classification based on the probabilistic motion law of particles on the screen surface. Its core feature is to optimize the screen surface parameters and vibration characteristics, allowing particles of different sizes to pass through the screen holes with different probabilities, thereby quickly completing coarse or medium screening operations. It is widely used in large-scale material pre-treatment in industries such as mining, coal, building materials, and chemical engineering, with a processing capacity of up to 180 t/h.It is a key pre-screening equipment for sand screening machines.

The discharge port is made of high-strength steel plate, featuring good wear resistance and sealing.
The size, angle, and quantity of the discharge outlet can be customized according to the material characteristics and production requirements, making it suitable for various industries such as mining, building materials, chemical industry, and sand and gravel.
The built-in flow-guiding and equalizing structure ensures that the material is evenly spread across the screen surface, preventing localized material accumulation, uneven distribution, and impacting. This significantly enhances screening efficiency and the pass rate of finished product granularity.

The GLS probability screen is an efficient and rapid classification device designed based on probability screening theory. Its core lies in the synergistic effect of multi-layer large-angle, large-aperture screen surfaces and high-frequency, low-amplitude linear vibration. It utilizes the difference in particle screening probabilities to achieve rapid material classification. It emphasizes "high throughput + low blockage + easy maintenance" and is widely used in industrial fields such as building materials, mining, and coal.
A frame that carries materials and the screen surface, typically constructed with welded steel plates, and must possess sufficient rigidity to prevent vibration and deformation
The core component of screening, typically consisting of multi-layered (1-5 layers) metal woven mesh or punched plates arranged at an angle, with the mesh size decreasing from top to bottom
Provides screening power. A common type is the "eccentric mass exciter", which can adjust amplitude and frequency to accommodate different materials
It supports the screen box and absorbs vibration energy, typically utilizing spring components to reduce the impact of equipment vibration on the foundation

High processing capacity: Due to the large inclination angle of the screen surface and the fast material movement speed (typically 0.8-1.5m/s), the amount of material passing through the screen surface per unit time is much higher than that of ordinary vibrating screens, making it suitable for large-scale production lines (such as coal mine raw coal grading, with a single unit processing capacity of up to 1000-3000t/h); High screening efficiency: Particles primarily move in a "tossing" manner, reducing material accumulation on the screen surface. Small particles have more opportunities to pass through the screen, resulting in a screening efficiency of up to 85%-95%; Simple structure and low energy consumption: no complex transmission components, light equipment weight (30%-50% lighter than ordinary screens with the same processing capacity), and operating energy consumption only 60%-80% of ordinary vibrating screens; Difficulty in blocking holes: The throwing motion of the material can effectively clear the blocked particles inside the screen holes (especially for wet or less viscous materials), reducing downtime for cleaning.
GLS probability screen: The processing capacity of a single unit can reach 15-200t, with a screen surface inclination of 15°-30°. The screening efficiency can reach 60%-80%, suitable for coarse screening and pre-screening of raw coal, ore, etc Ordinary vibrating screen: The processing capacity of a single unit can reach 1-20t, with a screen surface inclination of 5°-10°. The screening efficiency can reach 70%-85%, suitable for fine screening or moderate screening.
