This screen is ideal for working with materials having a bulk mass up to 2.8 t/m³ and is designed for use with a screening surface inclination angle from 0 to 5 degrees. The screen can be used for a variety of operations including dewatering, desliming, wet and dry screening (with a surface moisture content of less than 10%), and for washing suspensions from beneficiation products. It is capable of handling bulk materials with feed lump sizes up to 300 mm.

Advantages and design features

The GIST-72M screen is equipped with the latest design solutions that significantly improve its vibration dynamic and technological performance. It is equipped with various types of screens, including slotted screens, metal screens made of wear-resistant steel, rubber elastic screening surfaces (ESP) and wire screens with spherical installation and transverse tensioning. These features improve sieving efficiency and provide better separation of materials.

The screen is equipped with built-in vibrators of block type, which provide increased maintainability and allow operation with thick or liquid lubrication. Adjustable vibration amplitude and motor speeds (750 rpm and 1000 rpm) allow optimal adjustment of the equipment for different screening operations. The dust protection of the bearing units has also been improved, which contributes to the reliability and durability of the screen.

The GIST-72M screen has a high capacity, which can reach 500 tons of feed product per hour when using screens with the mesh size of the upper tier of 13x13x300 mm and the lower tier of 0.5x6x300 mm. The sieving surface of one tier is 2500 mm wide and 6705 mm long, providing a total usable sieving area of 32 m². These dimensions allow large volumes of material to be handled efficiently, making the screen ideal for large-scale production facilities.

The equipment is equipped with two tiers of sieves, which contributes to better particle separation and higher productivity. The adjustable vibration amplitude varies from 3.6 to 7.5 mm depending on the vibration frequency (12.2 s-¹ at 750 rpm and 16.2 s-¹ at 1000 rpm). These parameters allow the screen to be fine-tuned to the different requirements and characteristics of the material being processed.

The overall dimensions of the oscillating part of the screen are 6800 mm in length, 3220 mm in width and 2380 mm in height. These dimensions provide the necessary space for handling large volumes of material and contribute to the stable operation of the equipment.

The GIST-72M screen is equipped with electric motors with power of 44 kW at 750 rpm and 37 kW at 1000 rpm, which ensures its reliable and efficient operation. Power supply is provided from the mains with voltage of 380 V and frequency of 50 Hz.

Applications and uses

The GIST-72M screen is used in a variety of industries including mining, construction and processing. It is ideal for screening, dewatering and desliming operations, as well as for washing slurries from beneficiation products. Its high performance and versatility make it a valuable tool for companies that require efficient and reliable bulk material handling equipment.
