Probability screening is a screening machine that actively utilizes the principle of probability screening. The probability sieve commonly referred to is a vibrating probability sieve, whose screen surface is subjected to linear vibration by an excitation device. This probability sieve has been widely used in industrial sectors such as metallurgy, building materials, and coal to classify the particle size of medium and fine-grained materials. The main difference in structure between vibrating probability screens and flexible vibrating screens is that vibrating probability screens use multiple layers (usually 3-6 layers), large inclination angles (usually 30 ° -60 °), and large sieve holes (sieve hole size is 2 to 10 times the separation particle size) on the screen surface.
Multi level grading of mechanism sand or natural sand, with a screening mesh size of 5mm~2.36mm~1.2mm~0.6mm. Some special mortars have been screened to 0.3mm~0.15mm~0.075mm.
The output can reach over 80 tons per hour, and a single machine can achieve the production capacity of multiple ordinary vibrating screens, making on-site layout easier.
The curved design of the screen surface ensures a long lifespan for the screen mesh.
Closed design with up to five layers, detachable rear and front discharge ports for quick replacement of screen mesh.
The equipment cover is designed with a dust removal device, which can be connected to on-site dust removal equipment to meet screening requirements.
Introducing advanced technologies from countries such as Germany and Spain, continuously researching and on-site verifying, and demonstrating advanced technology.
Probability screening is a screening machine that actively utilizes the principle of probability screening. This screening theory states that the duration of retention of each object inside during operation is inversely proportional to its size and weight. Through practical experiments, it has been found that when the particle size is much smaller than that of the cavity, it can quickly pass through the surface of the screening surface. The closer the particle size is to the diameter of the cavity, the longer the retention time. If the diameters of both parties are close, the retention time of the particle is longer. In layman's terms, larger particles have longer retention time and smaller particles have shorter retention time.
After the screening machine is started, two symmetrically arranged vibration motors or exciters of the same model and specification operate synchronously in reverse. The excitation force generated by them is transmitted to the entire vibrating body screen box through the transmission body motor or exciter base, causing the screen box to drive the screen surface to vibrate periodically, thereby causing the material on the screen surface to perform directional jumping motion together with the screen box. During this process, materials smaller than the screen surface aperture fall into the lower layer through the screen holes, becoming undersized materials. Materials larger than the screen surface aperture are discharged from the discharge port through continuous jumping motion, completing the screening operation.

Comparison with traditional vibrating screens
A GLS probability sieve in the sand making screening system can be classified into multiple specifications, with a production capacity of more than 50-250 tons per hour. It has low investment cost and occupies less land. The probability sieve can be equipped with a cleaning device to avoid hole blockage. The traditional sand making screening system has a screening aperture as small as 5mm and up to 3 layers. Screening equipment is required for sizes below 5mm, and the production capacity is low, increasing costs and land occupation.
