Hammer Mill Feed Grinder Advantages

The particle size of crushed raw materials has a very important influence on the difficulty of subsequent processes (such as granulation, etc.) and the quality of the finished product. The size of the crushed particle size directly affects the feed mill production cost. When producing powdered compound feed by feed hammer mill, the power consumption of the crushing process is about 50%~70% of the total power consumption.

The smaller the crushing particle size, the more conducive to animal digestion and absorption, and the more conducive to granulation, but at the same time, the power consumption will increase accordingly.

Therefore, how to play the best production state of the feed mill grinder, reduce the feed mill production cost, and improve the production level and quality of feed pulverization is an important issue related to the production efficiency of the entire feed processing.

The latest upgraded RICHI feed grinding machine defines new industry standards and is tailored for your needs. More reliable product quality, higher work efficiency, and lower use costs are your first choice for profit.

As a manufacturer specializing in animal feed hammer mill grinding machine, Richi Machinery actively promotes the global strategy, cultivates an international business model, and has accumulated rich practical experience. The customer market covers six continents: Asia, Europe, Africa, North and South America and Oceania.


Working Principle Of Hammer Mill Feed Grinder

The working principle of electric feed grinder is that the products are input from the feed, and in the crushing chamber, they collide with the hammers in the high-speed rotating state, and are brought into the acceleration zone..

Under the action of its own gravity, the material enters the output of the feed grinding machine, and the particles that meet the requirements of pulverization can be discharged through the screen, and the particles that do not meet the requirements continue to be pulverized.

Structure Of Hammer Mill Feed Grinder

The structure of the feed grinder machine mainly includes the base, the feeding port, the crushing chamber, etc. The base is the installation base of the hammer mill grinder, which is used to support and connect the crushing rotor and other components.

Due to the main shaft, bearing, bearing seat, hammer frame plate, hammer plate, pin shaft and other parts, the role of the rotor component is to be in contact with the material during the rotation process. When a collision occurs, the material will be smashed. The main function of the hammer is to strike and smash the feed, which is a wear workpiece.

Structure Of Hammer Mill Feed Grinder

There are three types of hammer arrangement: spiral arrangement, symmetrical arrangement and staggered arrangement; in addition, the sieve piece is also one of the feed grinder machine parts that are easy to wear, and its function is to control the thickness of the feed. The tight window is fixed on the body to form a closed crushing chamber, so that the materials are crushed and screened out from the sieve holes to meet the crushing requirements.

Richi Machinery focus on high quality feed hammer mill production, and always in accordance with market trends and customer needs, constantly seeking changes and improving, timely innovation, and relying on its standard body, reasonable configuration, stable performance, mature design, has won the favor of customers on all continents around the world. It has played a positive role in major projects undertaken and participated by global feed manufacturers.

How To Choose A Hammer Mill Feed Grinder?

Selection based on production capacity

The feed grinder machine’s manual and nameplate will contain the feed grinder’s rated production capacity (kg/h). The stated rated production capacity refers to the output in a specific state of the feed grinding machine, such as a feed grain grinder, which means that the pulverized raw materials are corn, its moisture content is storage-safe moisture (about 13%), and the production efficiency when the sieve aperture diameter is 1.2mm.

Because corn is a commonly used grain feed, the sieve with a diameter of 1.2mm is the smallest sieve commonly used, and the production capacity is small at this time, which is the maximum production efficiency limit in production.

Therefore, when choosing a hammer mill grinder for corn, the production capacity should be slightly larger than the actual required production capacity, otherwise it will increase the wear of the hammer and the air leakage of the air duct, which will lead to a decline in production capacity, affecting the safe production of feed and the service life of the corn grinder for feed.

Selection according to the crushing object

Reasonable selection of the feed mill grinder according to the crushing object is an important prerequisite for ensuring product quality and improving production efficiency. In the feed processing process, if the grain feed is mainly crushed, the top-feeding hammer mill can be selected; Good performance, mainly for crushing grains, and taking into account the cake and straw, you can choose a tangential feeding hammer mill.

If it is used as a pre-treatment of pre-mixed feed, the particle size of the product is required to be very fine and can be processed according to needs. For adjustment, special sieveless feed grinders should be used.

choose hammer mill machine

Choose according to the layout method

There are three ways to output the pulverized finished product through the discharge device, namely self-weight blanking, negative pressure suction and mechanical conveying. Small single machine mostly adopts self-weight cutting method to simplify the structure. Most of the medium-sized feed grinders for sale are equipped with a negative pressure suction device. (Maybe you are interested in chicken feed pellet machine)

The advantage is that it can absorb the moisture of the pulverized material, reduce the humidity in the pulverized material and facilitate storage, improve the pulverization efficiency by 10% to 15%, and reduce the dust in the pulverizing chamber. , and the mechanical conveying method is to use a scraper or a bucket to convey the crushed material to the next processing and tempering link.

According to the matching power selection

The power range of the matched motor of this hammer mill feed grinder  is listed on the manual and the nameplate of the grinder. Depending on the variety and strength of the raw materials to be ground, the required power is also quite different. When the power is doubled, the crushing strength of soybean meal and cotton meal is similar, and the crushing strength of salt is the largest.

According to dust and noise selection

Most of the dust and noise generated in the processing of feed raw materials come from the hammer mill feed grinder. If a feed grinder machine with high noise and dust is selected, necessary noise reduction and dustproof measures should be taken to improve the working environment and reduce pollution and waste.

Especially in the production process of aquatic feed, the dust generated during the crushing process of feed raw materials is more prominent. This is because aquatic animals have small food intake, short digestive tracts, and poor digestion ability.

Usually, aquatic feeds are required to be pulverized more finely than livestock and poultry feeds. The larger it is, the digestibility of the feed can be improved and the feed rate of return can be increased.

Usually fish feed should be crushed to a geometric average particle size of 0.5mm or less before granulation. For example, ordinary freshwater fish meal should pass through a 20-mesh sieve, and no more than 30% of the materials above the 40-mesh sieve should pass through a 40-mesh sieve. 80% pass through a 60-mesh sieve, eel and soft-shell turtle feeds are required to pass through a 60-mesh sieve, and 95% pass through an 80-mesh sieve.

Therefore, in the process of crushing these feeds, adequate noise reduction and dust-proof work should be done.

buy feed hammer mill grinder machine


  • When producing aquafeed, a micro-grinder must be selected. It is difficult for ordinary micro feed grinders with sieves to have a crushing particle size below 0.25mm, otherwise the efficiency will be very low, and they can meet the feed crushing requirements of general fish (such as carp, grass carp, etc.) or larger fish.

    The sieve and sieveless feed grinder machine using airflow classification can meet the processing requirements of eel, shrimp feed, etc., and the particle size can be conveniently adjusted steplessly (within a certain range).

    Air-flow classification feed grinding machines with built-in classification screens or devices have greater advantages. They simplify the management of equipment and save investment.
  • When processing cattle and sheep feed, it is necessary to chop, pulverize and knead raw materials such as straw and hay, so it is most appropriate to choose a model that integrates these three functions.

    Here, the function of chopping should meet the requirements of chopping different kinds of straw and hay and continuously adjusting chopping length.

Operation And Maintenance Of Hammer Mill Feed Grinder

If you choose a good hammer mill for feed grinding, if you do not pay attention to the correct use and maintenance, it will shorten the service life of the feed grinder , and also affect the work efficiency, resulting in twice the result with half the effort.

Attention should be paid to the safe operation and daily maintenance of the feed hammer mill machine. (Maybe you are interested in: poultry feed pellet making machine)

01 Safe Operation Of Hammer Mill Feed Grinder

  • For long-term operation of the feed grinder machine, it should be fixed on the cement foundation. If the working location is changed frequently, the feed grinding machine and the motor should be installed on the frame made of angle iron, and the anti-vibration device should be installed. If the hammer mill feed crusher is powered by a diesel engine, the power of the two should be matched, that is, the power of the diesel engine is slightly larger than that of the feed grain grinder, and make the pulley grooves of the two consistent, and the outer end faces of the pulleys are on the same plane.
  • After the feed grinder crusher is installed, check the fastening of each fastener, and tighten it if it is loose.
  • Check whether the belt tightness is appropriate and whether the motor shaft and the feed hammer mill shaft are parallel.
  • Before starting the feed hammer mill, first turn the rotor by hand to check whether the hammer and the rotor operate flexibly and reliably, whether there is any collision in the shell, whether the rotation direction of the rotor is consistent with the direction indicated by the arrow on the machine, and whether the motor and the feed grinder are well lubricated.
hammer mill manufacturer
  • Do not replace the pulley casually, in order to prevent the crushing chamber from exploding due to too high rotating speed, or the working efficiency being affected if the rotating speed is too low.
  • After the feed grinder is started, it will idle for 2 to 3 minutes, and then start feeding and work if there is no abnormal phenomenon.
  • Pay attention to the operation of the crusher at any time during work.
  • Conditions, the feeding should be uniform to avoid blocking the boring car, and do not overload for a long time. If it is found that there are vibrations, noises, high temperature of the bearing and the substrate, and material spraying out, it should be stopped immediately for inspection, and the work can be continued after troubleshooting.
  • Clean up the iron removal device in time to avoid accidents such as copper and iron entering the crushing chamber.

02 Daily Maintenance Of The Hammer Mill Feed Grinder

The necessary daily maintenance and repair of the hammer mill machine should be carried out to prevent the failure of the feed grinder machine and prolong its service life.

Repair and replacement of screen mesh

The screen is made of punched thin steel plate or iron sheet. When the screen is worn or broken down by foreign objects, if the damaged area is not large, it can be repaired by riveting and soldering; if it is damaged in a large area, a new screen should be replaced.

When installing the screen, the burr side of the screen hole should be facing inward, the smooth side should be facing out, and the screen and the screen frame should be tightly fitted. When the ring screen screen is installed, the stubble of the inner layer of the connection should be along the direction of rotation to prevent the material from being stuck at the connection. (Hot post: animal feed mill plant)

Bearing lubrication and replacement

The bearings should be cleaned after every 300 hours of operation of the hammer mill for feed grinding. If the bearing is lubricated by oil, it is advisable to fill the bearing seat with 1/3 of the gap when adding new oil, and no more than 1/2 at most. Just tighten the cover of the constant-cover oil cup a little before operation.

When the bearing of the feed grinder machine is seriously worn or damaged, it should be replaced in time, and attention should be paid to strengthening lubrication; if the tapered roller bearing is used, the axial spacing of the bearing should be checked to keep it at 0.2~0.4mm. The paper pad at the bearing cap can be adjusted.

Replacement of hammer

Among the crushing parts, the hammer is the vulnerable part of the hammer mill feed grinder , and it is also the main component that affects the crushing quality and production efficiency. The hammer should be replaced in time after wear. Some of the hammers of the feed grinding machine are symmetrical.

When the hammers are worn to 5mm, they should all be replaced, and it should be noted that the weight difference of each group of hammers should not be greater than 5g; After completion, a static balance test should be done to keep the rotor balanced and prevent the unit from vibrating.

In addition, due to the wear and tear of the pin shaft of the fixed hammer and the circular hole where the pin shaft is installed, the pin shaft will gradually become finer, and the circular hole will gradually become larger, should be repaired or replaced in time.
