A grain conveying system moves grain between your receiving area, dryer, bins and trucks, and the right setup depends on your grain, your capacity and how far and how high the grain has to travel. Augers, belts, drag conveyors, grain pumps, air systems and bucket elevators each fit a different job, so the best system is usually a mix of them working together.
Agri-Systems helps farms and commercial sites plan grain handling systems that fit their needs today and leave room to grow. Before you buy a conveyor, find out where grain slows down in your system. A fast conveyor will not help if a slower machine sits before or after it. This guide explains each type in plain words and shows you how to pick, size and protect the right conveyors for your operation.
What Is a Conveying System in Grain Handling?
A conveying system is the full set of machines, spouts and controls that move grain so nobody has to lift or carry it. A single conveyor moves grain from one spot to the next. A conveying system links many of them together, so grain can travel from the truck to the bin and back out again.
Think of it like roads in a town. One road helps, but a set of roads that connect well is what gets you where you need to go. When the machines in your system are chosen to work together, grain keeps moving and trucks do not sit in line waiting.
How Does a Grain Conveying System Work From Truck to Bin?
Grain enters at a receiving point, moves through conveyors to a dryer or bin, and later travels back out when it is time to sell. A truck first dumps grain into a pit or onto a drag conveyor. From there, a bucket elevator lifts the grain high into the air. Farmers often call this tall machine a grain leg.
At the top, a distributor picks which bin or dryer gets the grain, and gravity does the rest through the spouting. Every spot where grain passes from one machine to the next is called a transfer point. These spots matter because grain can break there, dust can rise there and the flow can slow down there.
What Are the Main Types of Grain Conveyors?
The main types are augers, belt conveyors, drag conveyors, grain pumps, air systems and bucket elevators. Each one is best at a different job.
Augers
An auger is a tube with a spinning screw inside. It is simple, easy to move and good for short trips and steep angles. The downside is that it can be rough on grain, and the screw wears down over time.
Belt Conveyors
A belt conveyor carries grain on a moving belt. It is a good pick for gentle handling over longer runs that are flat or only slightly tilted. It does not work well on steep slopes because grain can slide backward. The belt itself matters a lot, because its width, speed and strength decide how much grain it can carry and how long it lasts.
Drag Conveyors
A drag conveyor pulls grain through an enclosed trough using a chain with paddles. It moves a lot of grain fast, and because it is closed, less dust gets out. It is common for filling bins, and many large sites use a high-speed drag conveyor instead of a dump pit to unload trucks quickly.
Grain Pumps
A grain pump moves grain through a tube using a chain with discs. It handles grain gently and sits in the middle of augers and bigger systems when it comes to price.
Air Systems
An air system pushes grain through pipes using moving air. It turns corners easily and fits in tight spaces. It does need a blower, so you have to plan for the power.
Bucket Elevators
A bucket elevator lifts grain straight up in small buckets on a belt or chain. It is the best choice when grain has to go high, like into the top of a tall bin.
How Do You Choose the Right Conveyor for Your Operation?
Start with five questions. What grain are you moving, how many bushels per hour do you need, how far does it go, how high does it go and how gently must it be handled?
Your grain comes first. Corn and soybeans are tough, but seed needs softer handling. Next, consider the amount of grain you need to move during peak harvest periods. Then measure the distance and the height. A short, steep run often points to an auger. A long, flat run often points to a belt. A straight lift points to a leg. Last, think about your budget and your space. A conveyor that fits your site and does the job well is better than a cheap one that keeps breaking down.
How Do You Size Conveyors So Every Part of the System Matches?
Size your conveyors for the days when you harvest the most, then make sure every machine in the chain can keep up. A system moves only as fast as its slowest part. If your leg can lift 10,000 bushels an hour but your receiving conveyor moves 6,000, your whole system runs at 6,000. Do not plan from yearly totals. Use real numbers from your busiest days and leave some extra room.
In a 2019 study published in Computers and Electronics in Agriculture, Aaron P. Turner and colleagues at the University of Kentucky built a computer model of grain moving from the field to storage, including the trucks and drivers. The team used 18 days of real harvest data from three farm setups. The model came close to real life, with a median error of 4.1 percent in daily deliveries. Even so, the number of loads in a day swung by about 27.8 percent on average when the inputs stayed the same. In simple words, harvest days are never alike, so a system built for an average day will struggle on a busy one.
Tip: Write down how many loads you handle each hour for a few harvest days, then size your conveyors for the busy days, not the slow ones.
How Does Your Conveyor Choice Affect Grain Quality?
Rough handling, fast speeds and long drops can crack kernels, make fine dust and lower your grain grade. Gentle conveyors and short drops help protect your grain. Every time grain hits a wall or falls a long way, a few kernels break. The broken bits are called fines. Fines are a problem in a bin because they can block airflow and make spoilage more likely. A conveyor that runs with a steady flow of grain is usually kinder than one that is overloaded or runs too fast.
A 2015 study in Applied Engineering in Agriculture, led by Wesley M. Porter and colleagues at the University of Georgia, compared a wire belt conveyor with a standard cross auger on a cotton stripper harvester. The crop was cotton, not grain, but the idea still helps. Fiber quality and the amount of trash in the cotton were about the same with both conveyors, and neither one clearly won. A field cleaner cut the trash a lot without hurting the fiber. In plain words, changing the conveyor type alone did not fix quality. The details of the design mattered more.
Tip: Do not assume a belt is always gentler than an auger. Ask for the specs and check for broken kernels at each transfer point.
What Safety and Dust Controls Does a Conveying System Need?
Every system needs enclosed housings, guards on moving parts, lockout points and good dust control. Grain dust can catch fire, so the goal is to keep it from building up.
Enclosed conveyors help hold dust inside. Anyone who works near a conveyor should shut it off and lock it out first. Clean up spills often, because dust piles up in corners and on ledges where it is easy to miss.
How Much Does a Grain Conveying System Cost?
The cost depends on the conveyor type, the capacity, the length, the height and the work needed to install it. A short auger costs far less than a long enclosed drag conveyor with a leg and catwalks.
On top of the machine, you pay for the foundation, electrical work, spouting and labor. Every site is different, so the only way to get a real number is a written estimate based on your layout. Try not to buy on price alone. A cheaper conveyor that is too small becomes the slow spot in the whole system and costs you more in lost time later.
What Controls Keep a Conveying System Running Smoothly?
Controls that start and stop conveyors in the right order keep grain from piling up when something stops. This is called an interlock. If the leg stops, the conveyor feeding it should stop right away, or grain will spill and jam.
Sensors can also warn you about a plugged spout, a belt that is drifting off track or a motor that is working too hard. These small parts can save you hours during harvest. Good upkeep helps too, and a simple before and after harvest maintenance routine keeps most problems from showing up in the middle of the season.
How Does Agri-Systems Plan Conveying Systems?
Agri-Systems draws your whole system in AutoCAD first, then supplies and installs the conveyors, legs and spouting to match. The team is based in Litchfield, Minnesota, and works with farms and commercial sites across the Midwest.
They sell and install augers, belt conveyors, drag conveyors, grain pumps and air systems, and they build each layout around your grain, your capacity and your site. If you want help planning yours, you can contact the team or call (800) 246-6094.
Conclusion
A good conveying system starts with knowing what you need to move, how fast it has to go and where it is headed. Once you know that, each type of conveyor has a clear place, from augers on short climbs to belts on long runs and legs on tall lifts.
Honest numbers from your own harvest, short drops between machines and the right safety and control parts turn separate machines into a system you can count on. Before you buy, write down your grain, your hourly goal and the limits of your site, and bring that list to your supplier.
Frequently Asked Questions
A conveyor is one machine that moves grain from one spot to another, while a conveying system combines multiple conveyors, spouts, and controls to move grain throughout a facility.
No single conveyor is best for every job. Augers suit short, steep moves, belts suit long and gentle runs, drag conveyors suit high volume, and bucket elevators suit lifting grain straight up.
Belt conveyors and grain pumps can handle grain gently, but grain damage also depends on conveyor speed, design and the distance grain drops at transfer points.
Find the most bushels per hour you will handle on your busiest harvest day. Then pick conveyors that can match that number, and add some extra room for growth.
Wet grain is harder to move because it sticks and builds up. Choose equipment made for your moisture level, clean it often and dry grain as soon as you can.
