A hammer mill is a mill whose purpose is to shred or crush aggregate material into smaller pieces by the repeated blows of little hammers. The basic principle is straightforward. A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while the material is fed into a feed hopper. The material is impacted by the hammer bars and is thereby shredded and expelled through screens in the drum of a selected size.
The hammermill can be used as a primary, secondary, or tertiary crusher. Small grain hammermills can be operated on household current. Large hammer mills used in automobile shredders may be driven by diesel or electric motors ranging from 2000 to over 5000 horsepower.
The screenless hammer mill uses airflow to separate small particles from larger ones. It is designed to be more reliable and is also claimed to be much cheaper and more energy-efficient than regular hammermills. The design & structure of the hammermill is always determined by the end-user.
A-Series Feed Hammer Mill
A-series feed hammer mill is a feed ingredient grinder machine. They are the ideal equipment for grinding grains like husks, maize, wheat, beans, peanut, etc. Into powdery materials by the repeated beating of little hammers. A-series Feed Hammer Mill is designed for small- and medium-scale feed and food processing enterprises. It is an important part of the feed pellet production line. It has many advantages, such as simple structure, reliable operation, and convenient maintenance. These advantages bring about its popularity in the animal feed pellet plant.
Working Principle of A-series Feed Hammer Mill
There are three grinding ways of A-series feed hammer mills to reduce material size: 1) explosion from the impact of the hammers; 2) cutting by the edge of the hammers; and 3) attrition or rubbing action. Material is ground in the grinding chamber until it is reduced to the required size. The number of hammers on a rotating shaft, hammer size, arrangement, sharpness, speed of rotation, wear patterns, and clearance at the tip relative to the screen or striking plate are important variables in grinding capacity and the quality of finished products. The heat generated from the grinding process is related to the material grinding time within the chamber and the airflow characteristics. Our Various materials can be reduced the size by our A-series feed grinding machine with proper screen selection and regulated intake, especially for grinding dry, low-fat ingredients.
Structure of A-series Feed Grinding Machinegrinding_chamber_of_A_series_feed_hammer_mill
It consists of the delivery devices, hammers, screens, pins, flow directors, grinding chamber, bearings, screen carriage, wear liners, and couplings.
● The delivery device is used to feed the material into the grinding chamber.
● Free-swinging hammers that are suspended from rods carry out the function of smashing the ingredients in order to reduce their particle size.
● The screen (usually perforated metal) is mounted below, above, and/or around the hammers through which the ground materials can pass through.
● The hammers do not touch the screens. If you want to chop hay, set hammers farther away from the screen. In this way, you will use less power and will get less fine material (power, flour, dust, etc.). If a fine powdery material is required, the hammers should be very close to the screen and more power is consumed.
Features and Advantages of Our Feed Hammer Mill

Animal Feed Hammer Mill Feed Mill Grinder
The hammer mill mainly relies on the impact energy to complete the crushing material operation. Feed mill grinder ;is working, the motor drives the rotor high-speed rotation, the material into the crusher chamber evenly and high-speed rotary hammer impact, cut apart the material to the material being broken, at the same time, the material's own gravity makes material from the high-speed rotating hammerhead to the body panel, sieve, resistance is greater than the screen hole size of materials on the sieve plate continues to hit by the hammer and the grinding, crushing to the discharging granularity until the final through the sieve plate outside.
Hammermills are mainly relied on impact to break materials. The material in the small hammer mill, suffered shattered by the impact of the high-speed rotary hammer, the crushed material, obtained from hammer broken hammer kinetic energy, from high speed toward the body flap, screen, meanwhile material impact each other, have been broken many times, from the gap eduction, individual large material, again by the impact of the hammerhead, grinding, extrusion and crushing, the material being hammer broken hammer out from the gap. To get the desired granularity of the product.
Design, modeling, and simulation of feed mixing machine
The idea of mixing various feed materials such as grains, feed supplements, and other animal feeds to produce a homogenous mix ready for dispensing for animal consumption had being part of man?s activities since the creation of man. This has always been done using crude methods such as hands, sticks, etc. in this recent time, the advancement in technology has brought about the use of machines to perform the same function much faster, accurately, and less energy-consuming. It is for this purpose that the feed mixing machine ;has been designed. The objective of this project is to design a small feed fixing machine, model and simulate the machine before production, fabricate components of the feed mixing machine based on design specifications, and test the machine after fabrication, while in designing and material selection consideration was given to the tech-economic status of the micro-scale industries who are intended users of the machine. Feed mixing machines are used in feed mills for the mixing of feed ingredients. The machine plays a vital role in the feed production process, with efficient mixing being key to good feed production. If the feed is not mixed properly, ingredients and nutrients will not be properly distributed within a précised time. This means that the feed will not have even nutritional benefits and would be bad for the birds that are feeding on the feed. Feed mixing machine comprises a frame structure, the mixing chamber (a cylinder and cone structure) where other components such as an electric motor, shaft, and hopper are mounted on. The mixing of feed to form a uniform ration is a regular need for large stock poultry purposes. The mixing is performed by a vertical shaft that revolves continuously in a cylindrical cone suspended by an iron bar. The relative motion of the shaft about the frame (body) is achieved by the use of knuckle bearing. Mixing is done in the mixing chamber. The mixer is constructed to take a capacity of 30kg, but the excess capacity of 40kg was provided to take care of overloading .this machine was powered by a 1hp power motor.
Should You Build a Pellet Mill?
Crucial to running a profitable pellet mill of any size is to invest in a well-designed mill with quality equipment. It will be detrimental to your business if you invest in material-handling machinery and pellet mills that are not robust enough for the task. Quality equipment doesn’t come cheap, but it’s better than out-of-control maintenance costs and hours of unscheduled downtime.
Of course, you must also control construction costs. Yet while controlling up-front costs may seem contradictory to outfitting a mill with top-tier equipment, it doesn’t have to be. Change orders and engineering fees can drastically increase the cost of a pellet mill, as do things like the plant’s location and legal fees—none of which has anything to do with equipment or the long-term performance of the mill. Saving money on construction is possible, but it must be done by spending money well, not by opting for cheap machinery.
What's the difference between a feed pellet mill and a biomass pellet mill
A feed pellet mill ;is used to produce pellets that can feed livestock and poultry. There are several advantages to feeding animals pellets instead of mash food. First of all, animal performance can be improved. The feed intake, weight gain, and feed conversion will all be improved to a higher level. Animals fed by pellets spend less time and energy on eating and digesting than those fed by mash feed. And as the feed density has increased, the feed dustiness has decreased, the feed-borne pathogens have been destroyed in the pellets-making process, and animals are actually eating healthier than before.
