What Is a Feed Conveyor?

The main body of feed machinery is mainly composed of feeding, mixing, granulating, transmission and lubrication systems. Its working process is to require the powder with a moisture content of not more than 15% to enter the feeding auger from the hopper, adjust the speed of the stepless speed-regulating motor to obtain a suitable material flow rate, and then enter the mixer, stir with the stirring rod and steam Mix for quenching and tempering. If you need to add molasses or fat, add quenching with steam from the mixing drum. The amount of fat is generally not more than 3%, otherwise it is difficult to form. After tempering, the temperature of the powder can reach 64 85 . , Humidity of 14 to l 6%. Then through the chute through the optional iron absorption device to remove iron impurities mixed in the powder, and finally enter the pressing chamber for granulation.

Feed machinery

The main feed machinery is mainly composed of feeding,

Feed processing machinery can be divided into:

1. Base: It plays the role of connecting and supporting the various parts of the grinder to form a whole. The crushed material is discharged from under the base.

2. Rotor: It is composed of main shaft, hammer plate, pin shaft, hammer piece, bearing and other parts. It is the main moving part of the crusher. The rotor rotates at a high speed, and the dynamic balance test is performed without a pin and a hammer.

3. Operation door: The operation door must be opened to replace the screen or hammer. When the shredder is working, the operation door is locked by a door lock to ensure that the operation door cannot be opened by itself when the rotor rotates.

4. Upper casing: the upper part has a feeding port, the lower part is connected to the base, and the two sides are respectively equipped with sieve plates, which form a crushing chamber with the rotor, and the materials are crushed in the crushing chamber.

5. Feeding guide mechanism: make the material enter the crushing chamber from the left or right. The reversing control of the feed guide plate is manually controlled to ensure that the feed direction matches the rotation of the rotor.

6. Screen pressing structure: It is connected by a hard locking device to ensure that the sieve is fixed in the crusher.

7. Sieve beam: The sieve beam is fixed in the crusher with the sieve pressing mechanism.

The produced feed mill adopts a double rotor structure, which greatly improves the work efficiency.

The main advantages of feed machining are:

Many feed mills have problems with the process arrangement and operation technology of the pellet mill, which has caused the output to fall short of the expected design requirements, and the pellet surface is not smooth, low in hardness, easily broken, and high in powder content. The main reasons that affect the production efficiency of the granulator during the granulation process are as follows:

Feed extruder can be used for the expansion of raw materials such as corn, soybean, soybean meal, rapeseed meal, cottonseed meal, etc. using the principle of the extruder. Puffing machine, feed puffing machine, dry large puffing machine, feed puffing machine is used for puffing fish meal, bone meal, leather meal, blood meal, feather meal, oil residue, animal scraps, etc., and its effect fully meets feed standards! The aquatic feed extruder is widely used in feed factories, farms, etc. using the simple extruder principle. The feed extruder, aqua feed extruder, and extruded extruder produce extruded fruits that are also used for water feeding and water ornamental Feed, such as aquatic organisms such as shrimp, crab, eel, catfish, goldfish and frogs, can be used for a long time. Feed machinery, feed extruder is also a must-have product for feed for suckling pigs in feed mills. The French large extruder has less nutrition loss during the extruding process, which can achieve the purpose of increasing protein and is more conducive to animal digestion. Therefore, some cheap raw materials have been extruded by feed machinery, Beijing feed extruder, aquafeed extruder, It can replace valuable raw materials without affecting the quality of feed, reducing costs, and playing an important role in developing feed resources.

Proper use of feed mills

1. Long-term operation of the crusher should be fixed on the cement foundation. If the working place is frequently changed, the crusher and the motor should be installed on the base made of angle iron. If the crusher diesel is used as the power, the power of the two should be matched, that is, the power of the diesel engine is slightly greater than the power of the crusher. The grooves of the pulleys are the same, and the outer surfaces of the pulleys are on the same plane.

2. After the grinder is installed, check the tightening of each fastener and tighten it if it is loose.

3. Check whether the belt tightness is proper and whether the motor shaft and the shredder shaft are parallel.

4. Before starting the grinder, turn the rotor by hand to check whether the teeth, hammers, and rotor are running flexibly and reliably, whether there is a collision in the shell, and whether the rotation direction of the rotor is consistent with the direction indicated by the arrow on the machine. Whether the machine lubrication is good.

5. Don't replace the belt wheel casually, in case the rotation speed is too high to cause explosion in the crushing chamber, or the rotation speed is too low to affect the work efficiency.

6. After the crushing table is started, idle for 2 to 3 minutes, and then feed the material after there is no abnormal phenomenon.

7. Pay attention to the operation of the crusher at any time during work, and the feeding should be uniform to prevent blocking of the stuffy car, and do not run overload for a long time. If vibration, noise, excessive temperature of the bearing and the body, or external spraying are found, stop the machine immediately and check the fault before continuing the work.

8. The crushed materials should be carefully inspected to avoid accidents caused by hard objects such as copper, iron and stones entering the crushing chamber.

9. Operators should not wear gloves, and they should stand on the side of the grinder when feeding to prevent rebounding debris from hurting the face.

10. When clogged, it is strictly forbidden to feed or drag out the feed by hand or stick.

At present, the feed processing machinery generally used in China has a low productivity. For example, the maximum output of domestic extruder is 3 to 5 tons per hour, which is a certain gap compared with foreign countries. In terms of the development of feed processing machinery, the United States and Europe are ahead of the curve, with higher stand-alone equipment automation and complete equipment automatic control procedures. China's feed machinery industry should develop in a large-scale and intensive direction. By increasing sales, it can reduce production costs and management costs, and improve efficiency.

China's pulverizers should make further breakthroughs in load control technology and combine them with central control technology to achieve a complete simulation of each working state of the pulverizers. Develop a safe and reliable automatic sieve changing mechanism to prevent the pulverizers from stopping. Under the circumstances, automatic screen change is realized to reduce downtime, facilitate the production of different materials, and improve efficiency. The mixer mainly needs further research in the detection of discharge uniformity, automatic detection of leakage, and automatic cleaning after mixing. It is also necessary to study the control technology of the granulator for the time of material conditioning, such as different materials, The conditioner automatically adjusts the inclination angle, changes the residence time of the material in the conditioner, or realizes by the automatic adjustment of the blade angle of the conditioner. It is necessary to develop a dynamic automatic adjustment mechanism for the granulator press roller and ring die clearance. Equipment such as feed pelletizers must also be controlled in a timely manner to speed up feedback and improve product quality.

Today's feed companies in China need to increase investment and expand basic research. From the perspective of countries with a good development ratio in the feed machinery industry, many well-known feed machinery manufacturers have their own research institutions or cooperate with relevant research institutions for research. Most of the most advanced and cutting-edge technologies are in the hands of enterprises. They have Strong development momentum and competitiveness. Therefore, if China's feed machinery manufacturing enterprises participate in international competition, they must increase investment in scientific research and carry out cutting-edge basic research. In addition to the self-built scientific research institutes, the methods that can be adopted are very necessary and feasible to cooperate with relevant scientific research institutions, colleges and universities, and even other scientific research departments in related industries. Through this large-scale cooperation, advanced products are produced to enhance the competitiveness of enterprises in the international market.
