1. Multi-level sieving: Multi-level grading of machine sand or natural sand. The number of screens: 5mm ~ 2.36mm ~ 1.2mm ~ 0.6mm. Some special mortars have been sieved to 0.3mm ~ 0.15mm ~ 0.075mm;

2. High cost performance: Pioneer has succeeded in replacing expensive imported equipment in the production line of dry mortar by introducing advanced technology from Germany and Spain, continuous research and development and field verification;

3. Large output: The output of GLS probability screen can reach more than 80 tons per hour, and the capacity of multiple ordinary vibrating screens can be completed by a single unit, making the site layout easier

4. Long life: the screen surface of the screen is designed in an arc shape. The external ratchet tightening can easily control the screen surface to be tight and not loose, and the screen has a longer service life.

5. Design on demand: closed multi-layer design, can be designed up to five layers, fast screen change, the rear end of the equipment and the front discharge outlet are all detachable design, you can quickly change the screen of each layer;

6. Energy saving and environmental protection: The upper cover of the GLS probability sieve equipment is designed with a dust removal device, which can be easily connected to the on-site dust removal equipment to meet the screening requirements.

    Probability sieve is a kind of sieving machine that actively uses the principle of probabilistic sieving. The sieving theory states that the length of time that each object stays in the interior of the operation is inversely proportional to its size and weight. It has been found through actual experiments. When the particle thickness is much smaller than the cavity, it can quickly penetrate the surface of the sieve surface. The closer the particle diameter to the cavity diameter is, the longer the residence time is. If the diameters of the two sides are close, the residence time of the particle is long. Generally speaking, Large particles take a long time, and small particles take a short time.

     When the sieve is started, two symmetrically arranged vibration motors or shakers of the same type and specifications are operated synchronously and in reverse, and the excitation force generated by them is transmitted to the entire vibration through the vibration body-motor or shaker base. Body-sieve box, the sieve box drives the sieve surface to periodically vibrate, so that the material on the sieve surface moves with the sieve box in a directional jumping motion, during which the material smaller than the sieve surface diameter falls through the sieve hole to the lower layer, becoming Under the sieve, the material larger than the sieve surface diameter is discharged from the discharge port after continuous jumping motion to complete the screening operation.
