The function of the feed port is to enable the material to be balanced into the pulverizer. Press the feed direction to be divided into tangential, radial, and axial feed. The tangent feed type hammer pulverizer is used for semi-circular bottom sieves, usually in a small pulverizer. The axial feed can be mounted in the maximum range, which is advantageous to discharge the pulverized fine material in time. The radial feed hammer pulverizer is suitable for processing cereals, cake or other particles of non-large raw materials and larger production. The feed baffle can adjust the feed direction, and the rotor can be forward and reverse rotation, so that after a hammer is worn, the rotor is reversed without the need to change the hammer, and the other corner of the hammer can hit the material. Reduce the number of times of replacement of hammers.

123] The sieve package is outside the rotor, and the surrounded space is referred to as a pulverizing chamber, and the material is crushed in the pulverized chamber, and the fine particles are discharged by the screen, so the screen is mainly controlled.The effect of pulverized particle size. At the same time, the screen is also rubbed and sheared during the comminution. The center angle corresponding to the pulverizing chamber portion surrounded by the screen, referred to as a cladding angle, and the cladding angle is one of the main parameters of the screen. The screen is a hidden component. MDQ China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry

[123 ] The role of the mill body is mainly supporting the fixed working part, ensuring that the material is smoothly entering the pulverizing chamber, and the screen is placed in the inner cavity of the body, and it will be smashed and can be collected from the material of the screen. The mouth is smoothly discharged. MDQ China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
MDQ China Feed Industry Information Network – Based on Feed, Service Animal Husbandry 123] The working mechanism of the pulverizer is more complicated and there are many research. Now only introduce the work mechanism of everyone recognized top feeding hammer pulverizer. The raw material was fed into the pulverizing machine in the top of the pulverizer, and the falling speed was approximately 1.64 ~ 3.28m / s. The raw materials were hit by the top of the rotor, in the initial crush area, due to the raw material The difference in speed difference with the end of the hammer is very large, and most of the material flow is pulverized or broken. This area is also a unique material flow in the pulverized chamber and the screen surface in which the sieve capacity can be utilized to the screening capacity of the screening capacity of the entire diameter. Subsequently, the particulate material flow is accelerated by the hammer to form a circulation layer moved along the inner surface of the sieve, and the velocity of the circulation layer is slightly lower than the speed of the hammer end. The lower the material layer of the surface of the sifter, and the material layer near the end of the hammer is higher. This area is narrower and is called acceleration zones. The crushed material is designed to be discharged by the screen, and the speed should reach a vertical discharge speed perpendicular to the screen. The crushing material close to the screen is subjected to the friction of the sieve, and the cyclic speed is lowered and the centrifugal force, pressure, and airflow perpendicular to the sieve plane can be discharged from the screen. However, fundamentally, the flow rate of the circulation layer is high, so that the large particles affected by the center of heart, and the fine particles cannot be discharged in time, causing the wear of the hammer, elevated temperatures and excessive pulverization. .

1, Hammer MDQ China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
The hammer is the main one of the hammer pulverizer, and it is also the most vulnerable work. Parts, hammers are coupled to the hammer plate by means of a pin shaft. Its shape size, working density and arrangement, material materials and manufacturing process, etc., have a large impact on crushing efficiency and work quality.3] MDQ China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
The shape of the hammer is used, and the rectangular hammer is applied by its versatility, simple shape, easy to manufacture and saves raw materials. wide. It has two pin holes,
MDQ China feed industry information network – based on feed, service animal husbandry
One pin hole is connected to the pin, and can be rotated to work in four corners. At the angle surfacing tungsten carbide or special wear-resistant alloy, can extend the service life of 2 to 3 times, but the manufacturing cost is high. The abrasion resistance of the stepped hammer is similar, and the polygon hammer is similar to the sharp-shaped hammer, and they have the advantages of being smashed and the life is long, but the manufacturing is complex, high production cost.

The hammer of the hammer crusher has been standardized, and the Ministry of Machinery Industry according to the Chinese Agricultural Machinery in 1986 Three specifications are rectangular double-hole hammers, including the I-type used for small pulverizer, and the choice of material and heat treatment processes. At present, there is a variety of ways with low-carbon steel solid carburizing quenching, medium carbon steel heat treatment, special cast iron and wear-resistant alloys in hammer working corps. Regardless of the methods, while ensuring wear-resistant and durable, the hammer is guaranteed to withstand the impact and production safety. Use 45, 65! When high quality steel such as 65MN, 60SIMN, the hardness of the hard treatment is hrc50 to 57 after heat treatment, and the hardness of the non-quenched region does not exceed HRC28. The hammer should be used in the case of 60 to 100 hours.

The most common method is to surf the tungsten carbide alloy, the welding layer is 1 ~ 3 mm. His life has increased by 7 to 8 times higher than the 65MN integral quenching hammer, but the cost is 2 times higher. The disadvantage of the solder tungsten carbide hammer is that the welding process and the rotor balance are high.

The position of the hammer is mounted on the rotor pin, said that it is arranged. It is related to the balance of the rotor, the distribution of the material in the comminuted chamber, the uniformity of the hammer wear. Requirements for the hammer arrangement: The movement trajectory of the hammer is not repeated, and the movement along the pulverizing chamber width hammer is uniform, the material is not pushing to the side, which is advantageous for the balance of the rotor. There are 4 commonly used hammers arrangements.
MDQ China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
1] Single spiral and double helix. The arrangement is simple, and the trajectory is uniform and not repeated. The disadvantage is that the material will be removed by the material in the operation, so that the side hammer wear is exacerbated, and the pulverizing chamber is not uniform in the width (axial direction) direction. Pins I and III (or II or IV) – Cartrombodyns R1 and R3 (or R2 andR4) The action line is equal to E gt; 0, the two Forces cannot be balanced. When the rotor rotates, the imbalance moment occurs, and the machine generates a vibration. Therefore, the application is getting less.
MDQ China Feed Industry Information Network – Symmetric Arrangement: Ammetric Shaft I and III, IV Symmetric Installation on Symmetric Shaft I and III, IV. Symmetric aligned hammer motion trajectory repeats, with more hammers in the same trajectory density. The advantage is that the centrifugal force of the symmetrical pin is equal to E u003d 0 and the size is equal, so it can be balanced with each other, so the rotor is smooth, and the material is also uniform. The hammer wear is relatively uniform, so the application is the most widely used. MDQ China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
3] Some of the two types of two pieces, double-slice interlaced. The hammer trajectory is uniform and not repeated, the symmetric shaft is centrifugally, the synergistic can be balanced with each other, and the rotor operation is balanced. The disadvantage is that the material is slightly laminated, and there are many scalespaces in the pin shaft space, which is more complicated when replacing the hammer. MDQ China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
On the same plane, the symmetry is balanced with each other, so the balance is good, and it is also a hammer arrangement for applications.
MDQ China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
Hammer Crusher Replacing the Hammer, must be reinstated according to the manual or completely restored the hammer arrangement, so as not to destroy the rotor balance .

123] The screen is one of the main working components and lossants of the hammer pulverizer. It has a great influence on the mass of pulverization efficiency and pulverization. The sieves used on the hammer mill include three types of cylindrical pore sieves, conical hole sieves and fish scale. Since the cylindrical hole sieve is simple, it is convenient to manufacture, the most widely used. The cylindrical hole sieves are both a punched screen and a drilling screen. The punched screen is superior to the latter due to a punched screen of the punching screen. MDQ China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
The screen is mounted on the periphery of the pulverizer rotor, and the sieve is formed in different feed forms. The axially feed pulverizer typically forms a 360o-clad angle of the ring sieve, and the tangential feed pulverizer sieve angle is 180o, also known as half sieve. The radial feed (top feed) pulverizer, the sieve package angle is 300o, and sometimes a water drip shape is also made. Due to the top feeding or tangential feed, the material directly into the maximum line speed zone of the hammer with the airflow, so the crushing effect is better.
