Large-Capacity Maize Threshing Machine

The SL-368 maize threshing machine is a large-capacity, tow-behind thresher built for commercial grain operations. It is a serious industrial thresher that takes whole dry/wet maize cobs, separates the kernels, cleans the grain, and loads the truck in one continuous line.

A 30kW three-phase motor drives nail-tooth threshing at 20-30 tons of maize per hour. Three/Two dust-removal fans in series and a double-layer vibrating screen clean the grain in a single pass. The 3,800mm discharge spout loads straight into standard grain trucks or storage silos.

A 50-1,000 hectare grain farm, a regional depot, a seed processing plant, or a contract threshing crew buys this unit when hand-shelling or small-capacity machines can no longer keep up. If need more details, please contact us at any time!

5 Features of Commercial Maize Shelling Machine

Our large maize threshing machine has the following features attracting worldwide customers:

• Nail-Tooth Threshing Cylinder — Handle Wet Maize at 20-30% Moisture
  • Right pick for high-moisture maize
  • Higher throughput and tolerate 25-30% moisture without kernel damage
  • Suitable for tropical and subtropical regions—Southeast Asia, West Africa, South America, southern China
• Three/Two-Group Dust-Removal Fan — Cleaner Grain, Higher Grade
  • Three or two dust-removal fans in series for lighter cleaning
  • Unique design: lift grain cleanliness by 30-40% and bring the finished product within commercial grade 2 or better
• Double-Layer Vibrating Screen — Two-Stage Cleaning in One Pass
  • Upper coarse screen for large debris that slipped past the fans: cob pieces, husk chunks, unthreshed cobs
  • Lower fine screen for small impurities: broken kernels, dust, sand
  • Deliver a cleaner finished product and cut the manual recleaning step at the depot
• 3,800mm Discharge Height — Direct Load to Truck or Silo
  • Remove the second handling step (shoveling, sweeping, bagging) and keep the threshing line moving at full capacity
  • Adjustable chute so the operator aims the stream into the truck bed without moving the thresher
• Tow-Behind Design — Just 30kW Three-Phase Power
  • Steady and predictable power —no diesel refueling stops mid-shift
  • For buyers with stable three-phase power at the depot, electric threshing costs 30-50% less per ton than a diesel equivalent

How the SL-368 Maize Threshing Machine Works

The SL-368 corn thresher runs on a four-step cycle that one operator can supervise without leaving the control station.

1. Feed whole cobs. The operator feeds whole, unhusked maize cobs into the hopper at the top of the machine. A feeding auger pulls cobs into the threshing chamber at a steady rate—no pre-shelling or pre-cutting needed.
2. Nail-tooth threshing. The high-speed cylinder (driven by the 30kW motor) strikes each cob against the concave. Kernels fall through the concave onto the vibrating screen, and empty cobs exit at the rear.
3. Three-stage air cleaning. The grain stream passes under the three dust-removal fans. Large debris, light impurities, and dust are blown out of the back of the machine. The cleaned grain continues to the vibrating screen.
4. Double-layer screening and discharge. The vibrating screen removes any remaining oversize and undersize particles. Cleaned grain rides the discharge auger up to the 3,800mm spout and loads straight into the waiting truck or silo.

Applications of Big Capacity Maize Corn Threshing Machine

• Large-scale grain farms (50-1,000 hectares). Replace hand-shelling and contract threshing crews with on-farm capacity that runs through the harvest queue on schedule.
• Regional grain depots and buying stations. Receive farmer deliveries, thresh on the spot, and load cleaned grain into long-haul trucks or silo storage. The 3.8m discharge loads directly.
• Seed processing plants. Clean threshing without kernel damage makes the SL-368 a fit for seed maize operations, where germination rate matters as much as throughput.
• Contract threshing crews. Move the tow-behind maize threshing machine unit from farm to farm during the harvest season. The 3-5 day order lead time means a new unit can be in service before the season starts.
• Livestock feed operations. Produce on-farm maize grain for feed mixing at the lowest per-ton cost.

For the next step after threshing, see the Taizy maize grits and flour milling machine and corn cleaner—the SL-368 is the upstream link in a complete post-harvest handling line.

SL-368 Maize Threshing Machine Price and ROI

This kind of thresher is built to industrial spec (2 tons, 30kW drive, 3.8m discharge), so it sits in the mid-to-upper price range for maize thresher machines. The exact FOB price depends on configuration: 2-fan vs 3-fan, voltage customization, optional spares. Contact our sales team for a current quote.

The differentiator is lead time. The SL-368 ships in 3-5 days from order confirmation. Most industrial threshers in this class ship in 15-25 days. For a buyer who needs to be operational before harvest opens, that 10-20 day gap is the difference between catching the early-season premium price and missing it.

A simple ROI example:

A regional depot running the SL-368 for 10 hours a day over a 60-day harvest produces 12,000-18,000 tons of cleaned maize. At a typical contract threshing fee of USD 5-8 per ton, gross revenue is USD 60,000-144,000. Operating cost (electricity, labor, maintenance) is usually 25-35% of gross, leaving net operating income of USD 40,000-95,000 over the season. The unit pays for itself in the first season for most buyers.
