Probability screen for sand and gravel aggregates, multi-layer vibrating screen for mining

Probability screen for sand and gravel aggregates, multi-layer vibrating screen for miningProbability screening is a screening machine that actively utilizes the principle of probability screening. The commonly referred to probability screen is a vibrating probability screen, whose screen surface undergoes linear vibration through an excitation device. This probability sieve is currently widely used in industries such as metallurgy, building materials, and coal for particle size classification of medium and fine grained materials. The main difference between a vibration probability screen and a variable vibration screen in terms of structure is that the vibration probability screen adopts a screen surface with multiple layers (usually 3-6 layers), a large inclination angle (usually 30 °~60 °), and a large mesh size (the mesh size is 2-10 times the separation particle size).

Application scope of probability sieve; Stone, sand, wet coal, crushed coal, stone powder, starch, salt, sugar, milk powder, pigment, medical powder, grease, rubber, plastic, epoxy resin, PVC resin particles, polyethylene powder, vinyl chloride resin, polymer particles, glass powder, refractory, silica sand, spray soil particles, slurry, abrasive materials, rice resistant brick, artificial black lead, kaolin, slaked lime, mica, limestone, potassium feldspar, calcite, dolomite, perlite, Granite, river pebbles, barite, basalt, zeolite, etc. Aluminum oxide, calcium carbonate, lead powder, zinc powder oxygen, alloy steel, iron powder, carbon black, light calcium, additives, pearl powder, etc., quartz sand, ceramic sand, petroleum proppant, fracturing sand, coated sand, pearl, sand quartz powder, refractory materials, chemical and other industries!

It has the following advantages:

1. Long service life of the screen: The low service life of the screen is the soft rib of the linear screen, and the service life of the screen is 15 days. The GLS probability screen can have a service life of over 40 days, with a service life of 2 months, which is 2-3 times that of the linear screen.

It is difficult to replace the screen. The linear screen is a mesh structure, and if one layer of screen is damaged, all the mesh frames must be removed. Each replacement of the screen takes over an hour. The GLS probability screen is easy to replace, and any layer of screen that you want to replace can be replaced separately. The sand production line generally has a high on-site environment, and frequent replacement of screens increases safety hazards.

2. Non blocking screen: The GLS probability screen has a strong penetration rate and high screening accuracy. The mortar grading screen has a special curved screen surface design, which allows for fast material dispersion, rapid discharge, and the formation of no material layer, greatly improving screening efficiency and solving problems such as slow feeding, thick material layer, and incomplete screening of ordinary vibrating screens. The GLS probability screen is equipped with an automatic cleaning device and anti blocking mesh design. The probability screen adopts a special rectangular hole double layer hook plate design made of special materials, which is reasonable in design and durable.

The overall sealing performance is good, continuous operation, and the probability screen is a fully enclosed structure designed reasonably and scientifically. The sealing performance is good, and it is environmentally friendly and pollution-free. This device can be used in conjunction with other devices for continuous operation.

3. Large production capacity: The GLS probability screen can produce up to 80 tons per hour.

The production of linear screening is low, and the screening accuracy is not up to standard. Multiple machines must be used to complete the process, making the distribution of the entire screening process difficult and costly.
