Corn Feed Grinder
The Corn Feed Grinder is an all-in-one feed processing machine integrating three core functions: self-priming corn grinding, forage chopping, and straw shredding. It suits the breeding of all types of livestock and poultry including cattle, sheep, pigs, chickens and ducks.
Its flagship feature is independent on-site grinding of corn feed. Equipped with a built-in wind-powered self-priming system, it requires no manual feeding. The suction pipe can directly draw corn from grain silos or woven sacks for automatic feeding and high-speed fine grinding, quickly producing corn fine concentrate feed for farming use. The fineness of powder can be freely adjusted by swapping different screens, meeting the feed particle size requirements for piglets, finishing pigs, laying hens and broilers at various growth stages.
In addition, it retains professional chopping and shredding capabilities to separately process all kinds of crop straw and forage grass. Dry straw is shredded into soft filaments to prevent selective feeding and esophageal injuries in livestock and poultry. Fresh green stalks can be made into silage to lock in forage nutrients.
This single unit handles both concentrate feed (corn powder) and roughage (straw filaments), serving dual purposes in one machine. It drastically cuts farm equipment investment costs and reduces space occupation.
Core Features of the Corn Feed Grinder
All-in-One Multifunctional Design
This machine integrates chopping, shredding and grinding functions without additional attachments. Switch between grinding and chopping-shredding modes with one single button. It efficiently processes corn feed as well as all kinds of forage grass. One unit replaces two separate machines, delivering outstanding cost performance.
Self-Priming Feeding System
The corn grinding section is fitted with a high-power self-priming fan for fully automatic material intake. It eliminates the tedious manual continuous feeding required by traditional grinders. A single operator can complete the whole workflow of feeding, grinding and discharging independently. The design prevents material jams and backflow at the inlet for smoother feeding, boosting processing speed by over 40%.
Dual Dry & Wet Processing Capacity
Optimized cutter assembly allows direct processing of both dry and fresh wet straw. Wet grass resists winding around the main shaft, while dry straw achieves full grinding without dead zones. Offset arranged shredding blades break straw into soft fine filaments with far better palatability than regular chopped segments, raising feed intake for cattle and sheep.
High-Power All-Copper Motor
A national standard all-copper motor comes as standard, delivering powerful output with low temperature rise to avoid burnout during long-hour continuous operation. The frame is constructed from thickened steel plates, paired with quenched high-manganese steel cutting heads featuring high hardness and abrasion resistance. The blades resist curling or deformation even when grinding hard corn kernels and coarse straw for extended periods, boasting a far longer service life than ordinary iron cutters.
Adjustable Fineness with Multiple Grades
Multiple screens of different sizes are supplied. Corn can be ground into fine powder, medium powder or coarse granules: fine powder suits chicks and piglets, medium powder for finishing livestock and poultry, and coarse granules for cattle and sheep. Operators may freely switch between straw chopping and shredding modes to produce feed as needed.
Comprehensive Safety Protection
A safety baffle is installed at the feeding inlet to avoid accidental contact with the high-speed rotating cutter assembly. An overload protection switch is built into the whole machine, which automatically cuts power and shuts down the unit if hard foreign objects cause blockages, safeguarding the motor and cutters. New operators can use the machine without safety risks.
Structure of the Corn Feed Grinder
Power Drive Unit
Consists of a standard all-copper motor and drive pulley. It delivers stable power transmission with low noise and minimal power loss, supplying ample power for both grinding and chopping-shredding systems.
Self-Priming Corn Grinding Chamber
Comprises a self-suction air duct, feeding hose, grinding hammers, interchangeable screens and powder discharge outlet. This section rapidly pulverizes corn kernels and corn cobs via impact crushing. Negative air pressure enables automatic material feeding, and finished corn powder is discharged automatically through the bottom outlet.
Forage Chopping & Shredding Chamber
Mounted on the side of the frame, it is equipped with forced feeding rollers, chopping blades, flail shredding knives and a forage discharge port. Straw is first cut into short segments then finely shredded for roughage processing. The two independent chambers operate without mutual interference; no disassembly of the machine frame is required to switch working modes.
Frame and Shock-Absorbing Base
The unit features an integrally welded thick steel frame that remains rigid and deformation-free. Shock-absorbing foot pads are fitted at the bottom to mitigate vibration and operating noise, keeping the machine stable during operation without anchoring to the ground.
Control Switches and Safety Protection Assemblies
Incorporates an integrated start-stop switch, emergency power-off button, inlet safety guard and sealed body covers. These components deliver full operational safety protection, contain flying dust and maintain a clean breeding environment.
Air Volume Regulator
Adjusts the airflow of the self-priming fan. Operators can modify suction strength according to corn moisture content and feeding speed, preventing dust splashing caused by excessive airflow or insufficient material intake from weak airflow.
Application Scenarios of the Corn Feed Grinder
1. Private small-scale breeding for cattle, sheep, pigs, chickens, ducks and geese at rural households
2. Integrated daily processing of concentrate and roughage for medium and small livestock farms
3. Straw recycling and corn feed preprocessing for rural agricultural cooperatives
