Feed Hammer Mill
An efficient crushing machine for the feed processing industry

Feed Hammer Mill Overview
The drop feed grinder is a type of grinding equipment commonly used in the feed processing industry. It has high efficiency and low energy consumption. Its structure is usually similar in shape to a drop, with a large grinding chamber and better airflow, which makes the grinding of materials more even.

Main structure and working principle of the hammer grinder
Main structure and Working Principle
Feed opening
The material enters the machine through the feed opening and directly into the crushing chamber. The feed opening is generously designed to facilitate even material transport and prevent blockages. Some models are also equipped with an automatic suction device.
Crushing chamber
The crushing chamber is the core component of the machine and contains the high-speed rotating hammer. The material is gradually crushed into small particles in the crushing chamber through impact, friction and shearing.
Hammer
The hammer breaks the material by impacting it at high speed. The replaceable hammer is made of wear-resistant steel and is shaped in such a way as to provide efficient crushing and a long service life.
Sieve
The sieve is located at the bottom of the crushing chamber and is used to control the particle size. Smaller particles are discharged through the sieve, while larger particles are returned for further crushing.
Discharge opening
The crushed material is discharged through the discharge opening. The machine can be equipped with an optional fan or conveyor belt to quickly transport the finished particles to the next process step and reduce backlogs.
Operating principle
After entering the crushing chamber, the material is crushed by the friction and shearing action of the high-speed counterattack hammer. Qualified particles are discharged through the screen, and unqualified particles continue to be crushed.
Features and Advantages of Feed Hammer Mill
Features and Advantages
Efficient grinding
The hammer mill uses a high-speed rotating hammer to repeatedly impact and rub the raw materials, quickly grinding large amounts of raw materials into small, uniform particles.
Adjustable particles
The machine is equipped with an adjustable screen, and users can replace screens with different apertures as needed to precisely control the particle size.
Wide range of applications
The hammer mill is suitable for materials of various hardness, including grains, straw, etc., and is widely used in the feed and food industries.
Energy-saving and durable
The hammer blades and screens are made of wear-resistant materials, and the simple structure of the equipment reduces maintenance costs.

Application scenarios of hammer mills in feed processing
Application Scenarios
Raw material grinding
Crushes large particles such as grains, corn and wheat into fine particles suitable for mixing and pelleting, improving the digestibility and absorption of the feed.
Coarse fiber treatment
Pre-treats coarse fiber materials such as grass, rice husks and straw, reduces the fiber content in pelleted feed, changes the palatability of the feed and improves feed utilization.
Meets production requirements
By adjusting the aperture of the screen, materials of different fineness can be crushed to meet the production requirements of various feed formulas.
Improve production efficiency
It can be used in conjunction with the mixing and pelleting equipment in the feed production line to significantly improve feed production efficiency.

Frequently Asked Questions.
The hammer feed grinder is suitable for grinding a wide range of materials, and is particularly suitable for grains (such as corn, soybeans, wheat, etc.), soybean meal, forage, straw, rice hulls and other raw materials. It is ideal for feed mills and grain processing plants.
The hammer feed grinder has a teardrop shape design, which means that the material stays in the grinding chamber for a short time and is evenly stressed. The high-speed rotating hammer blade repeatedly impacts the material to ensure that it is fully ground, resulting in a relatively uniform particle size.
To replace the screen, first stop the appliance and disconnect it from the power supply. Then remove the screen fastening device, remove the old screen, fit the new screen and ensure it is secure.
The feed grinder will produce some noise when in operation, especially the hammer blades colliding at high speeds, which will produce loud noise. Proper installation and regular maintenance of the equipment can also effectively reduce noise.
It has good compatibility and can be seamlessly connected with a hoist (to transport raw materials), a mixer (to evenly mix the ingredients), and a pelleting machine (to make pelleted feed) to form a complete feed production line.
