Grain Screw Conveyor

The effective operation of a modern agricultural enterprise is not always limited to the territory of a stationary grain elevator. Often there is an acute need to quickly load a grain truck right in the field, move a pile at the threshing floor, or organize product feed in floor storage warehouses where there are no capital bucket elevators. Precisely for such tasks, Zavod Moroza manufactures a simple, reliable, and mobile tool – the grain screw conveyor.

This is a universal solution that works on the "here and now" principle – the unit does not require the construction of intake pits, the design of galleries, or expensive concrete work. You simply roll the equipment to the pile, adjust the height, turn it on – and loading begins. The main specialization of our grain screw conveyor is gentle handling specifically with grain crops (wheat, corn, barley, sunflower). However, the potential of screw technology is much wider – our units are successfully used for fuel pellets, sawdust, and even building mixtures. However, it is worth remembering that working with abrasive or specific materials requires technical changes, and in such cases, our engineers will perform a separate calculation and select the appropriate auger flight thickness, drive power, and RPM to adapt the design to your specific tasks, guaranteeing equipment durability.

Versatility of Grain Screw Conveyor Application

Structurally, a grain screw conveyor is a continuous action mechanism designed to move bulk cargoes in a horizontal plane or at an angle (optimally up to 45-60°). Depending on production tasks, we offer two main variants of the unit configuration:

• Mobile screw conveyor on supports (stand)
  A budget solution for small farms, where the unit is equipped with a light collapsible tripod (without wheels). Such a design is stable in operation; the efforts of two people are enough to move it around the grain yard, and the discharge height is fixed mechanically.
• Mobile screw conveyor on wheels
  This model is the most balanced option because the presence of a wheel base allows one person to easily roll the unit on a flat surface (concrete, asphalt). The tilt angle is adjusted using telescopic struts (by repositioning pins) – this is convenient when working with same-type transport.
• Mobile screw conveyor on wheels with a winch
  A version of increased comfort for intensive work, because in addition to wheels, the frame is equipped with a reliable cable winch, which allows the operator to smoothly and accurately change the discharge height in seconds without stopping the process or applying physical effort – ideal for loading trucks of various sizes.
• Stationary screw conveyor
  Designed for installation in technological lines (for example, feeding from a hopper to a crusher). Supplied without a wheel frame but has special flanges or eyelets for rigid attachment to walls, ceilings, or supporting metal structures. Can be manufactured both in a tube (hermetic) and in an open trough.

Besides the construction type, it is important to determine the method of grain feeding. In the basic configuration, the "nose" of the grain screw conveyor is equipped with a protective metal mesh – this option is ideal for immersion directly into a grain pile, where the open part of the spiral automatically captures the material, ensuring continuous feed without the need for manual shoveling. However, if it is more convenient to pour material with shovels or from bags, we equip the loader with a compact intake hopper, which directs the entire flow of grain precisely onto the auger flights by gravity, preventing it from scattering sideways. For more intensive tasks, for example, receiving grain directly from a dump truck body, we offer an enlarged hopper with a horizontal feeder screw – it allows for operative reception of the product flow (with dosed opening of the side/tailgate or through a hatch), ensuring continuous feed into the main line without spillage.

Thanks to the sectional structure, we can manufacture a screw loader for grain or other bulk products of almost any necessary length (standard from 6 to 12 meters for mobile versions), simply connecting unified sections together. This significantly simplifies equipment transportation – even a long 12-meter loader in a disassembled state easily fits into the body of a light truck. Moreover, such modularity makes the design maximally flexible in operation – it allows scaling equipment to the current needs of the farm, changing the working length of the grain screw conveyor by adding or dismantling standard segments without welding work.

Technical Advantages and Design Features of Screw Conveyors

Our grain screw conveyors and bulk cargo transporters are designed on the principle of industrial endurance, not saving on materials. For work with grain crops, we use an auger flight made of structural steel with a thickness of 2.5-4 mm (depending on the pipe diameter), which ensures an optimal balance – the spiral is light enough not to overload the motor, but resistant to abrasion over many seasons. If work with abrasive materials (sand, coal dust) is planned, we install a reinforced spiral with a thickness of up to 6-8 mm. We also have experience in implementing complex engineering special projects for heavy industry and energy – our capacities allow manufacturing stationary lines up to 40 meters long, with a diameter up to 500 mm and a flight thickness up to 16 mm (for moving ore, slag, or cement). Such production potential is the best proof of quality – buying even a light grain screw conveyor, you receive a product created by designers who know how to successfully work with extreme loads.

A critically important element of durability is the protection of rotation units. Our units feature a scheme with external bearing supports – this means that the bearing is physically moved outside the pipe body on spacer bushings and does not contact the product flow, which completely eliminates dust entering the lubricant and overheating. Regarding the drive, we offer a choice for your tasks – a classic belt drive, where belts act as a fuse against jamming (relevant for mobile versions in the field), or a gear motor for direct force transmission (for compact stationary solutions). All sections are connected by precise flanges, ensuring ideal shaft alignment and absence of vibrations along the entire length of the conveyor. Such a combination of engineering solutions makes the construction monolithic and enduring, guaranteeing that the equipment will not let you down at the height of the season, when any risk of downtime costs too much.
