The shaft screw conveyor is driven by a driving device to rotate the central shaft, thereby enabling continuous material transportation within the trough. It is suitable for transporting various powdery, granular, and small block-like materials, such as grains, beans, flour and other food crops, cement, clay, crushed stones and other construction materials, acids, bases, fertilizers and other chemical products, as well as coal, coke, iron ore and other bulk bulk cargoes.
Shaftless Screw Conveyors is an efficient equipment specially designed for transporting viscous, easily tangled or high-humidity materials. Its core feature is that it eliminates the traditional central shaft with an axle, and instead uses an integral steel spiral blade to directly push the materials, significantly enhancing its adaptability to complex materials.
The high-speed rotation of the helical blades generates centrifugal force, causing the material to adhere closely to the inner wall of the shell. When the centrifugal force exceeds the frictional force between the material and the shell, the material ascends along the reverse helical line, achieving vertical transportation. The material filling rate can reach 30% to 60%, significantly higher than that of horizontal screws.The function of the vertical screw conveyor is particularly suitable for transporting dry granular or powder-like materials. It can save space and achieve efficient transportation.
The spiral feeder is a “material distributor” that connects the silo with downstream equipment (such as conveyors, mixers, reactors). Its main function is to continuously and uniformly convey the bulk materials in the silo to the next process. Unlike the “long-distance transportation” of ordinary spiral conveyors, the advantage of the spiral feeder is “flow controllability” and “bridge prevention capability”. The open-bottom silo is an “active discharge device” installed at the bottom of the silo. Its main function is to prevent the occurrence of bridging and segregation of materials in the silo, achieving overall material flow rather than funnel flow, and providing a stable material source for downstream feeders or conveyors.
The belt conveyor can achieve long-distance transportation through the circular movement of the looped conveyor belt, featuring high efficiency, low consumption, and flexible layout. It can be applied to almost all industries such as mining, construction materials, logistics, and food. Unlike the “spiral pushing” of the screw conveyor or the “material bucket scooping” of the bucket elevator, the belt conveyor can not only transport loose materials but also packaged items. It can be designed with different shapes according to process requirements and site conditions to meet the diversified transportation needs of different customers.
The scraper conveyor, also known as the dragging conveyor, is a transmission equipment that uses a scraper chain to drag the material within a closed or open trough for transportation. The scraper conveyor has advantages include resistance to wear, high temperature resistance, and adaptability to harsh environments. It is particularly suitable for transporting large particles, highly abrasive, high-temperature or impure bulk materials, and can be adapted to extreme usage scenarios. The material of scraper conveyoris generally made of carbon steel, stainless steel, or wear-resistant steel. The contact area between the material and the scraper chain is large, enabling the transportation of materials with poor fluidity, and the conveying direction is flexible.
