What is pelletizer machine? What's the pelletizer meaning? What's the importance of pelletizer? Why use pelletizer? For many customers who don't know much about the pelletizer machine, there must be your questions. Let RICHI explain it for you.
There are two main palletizer types, ring die pelletizer type and flat die pelletizer types. Because ring die pelletizer machines are widely used, flat die pellet machines are only suitable for small farms, households and other very small applications, so today we only Talk about the ring die pellet making machine that is really useful for everyone.
The ring die pelletizer machine is widely used in the processing of feed, the pelletizing of biomass energy such as straw and sawdust, the production of compound fertilizer, the pressing of marigold pellets, and the production of petroleum and plastic pellets. Different pelletizers are used for different materials, and the core part is the pelletizer ring die.
It is helpful to improve product quality and output, reduce energy consumption (granulation energy consumption accounts for 30%-35% of the total energy consumption of the entire pellet production plant), and reduce production costs (the cost of ring die loss accounts for 25%-30% of the maintenance cost of the entire pellet production line at least) and other aspects have great influence.
How does a pelletizer work? It's important to learn how a pelletizer works. Whether it is an automatic pelletizer or an industrial pelletizer, as long as it is a ring die pelletizer, the pelletizing machine working principle is the same. The pelletizer machine is the key mechanical equipment in the production of pellet. The most commonly used pelletizer is the ring die pelletizer, which is mainly composed of a hopper, a feeder, a security magnet, a conditioner, a chute, a door cover, and a pressing room. The main drive system, overload protection device and electrical control system, etc.
The working principle of the ring die pelletizer process is: the quenched and tempered crushed material is passed through the chute through the compression die cover, and the centrifugal force generated by the gravity and the rotation of the ring die and feeding The action of the scraper is evenly fed into the two pressing areas in the ring die.
Under the strong squeezing action of the ring die and the pressure roller, the material is gradually compacted and extruded into the die hole of the ring die and continuously extruded in a columnar shape. And adjust the distance between the cutter and the surface of the ring die to control the length of the pellets.
According to the pellet machine model, we mainly provide two types of pelletizer machine: SZLH pelletizer machine and MZLH pelletizer machine, which can cover the processing of various raw materials and pellets.
What is feed pelletizer machine? It's a pelletizer for animal feed. Pellet feed accounts for about 70% of developed countries. In recent years, pellet feed has developed rapidly. With the development of animal husbandry and aquaculture, the importance of pellet feed production has become more and more significant. Pellet feed has the following advantages:
In addition to animal feed pellets, such as cat litter pellets (bentonite, attapulgite) and other special raw materials and process requirements can also be processed by this model.
|Model||Feed Pelletizer Capacity||Power(kw)||Cost of pelletizer(USD)||Pellet Diameter (mm)||Pelletizer Die Compression Ratio For Different Feed Pellets|

|SZLH768 feed pelletizer||25-40||280/315|
|SLZH858 feed pelletizer||25-42||280/315|
The MZLH series ring die pellet mill is mainly used to suppress non-feed pellets such as agricultural and forestry waste, urban solid waste, and organic fertilizer. In addition to biomass pellets, organic fertilizer pellets, waste tire pellets, PET plastic pellets, cat litter pellets (wood chips, waste paper, etc.) can also be pressed. The main uses of the pellets pressed by this type of pelletizer machine are heating, power generation, enterprise production, road paving, chemical industry, etc.

|How Much Is Pelletizer Machine?||10000-100000USD|
Main pelletizing machine products include more than ten categories of main engine products such as feed pelletizer series, biomass pelletizer series, wood pelletizer machinery series, grass pelletizer series and organic fertilizer pelletizer series etc., as well as pelletizer accessories, such as pelletizer cutter, pelletizer knives, pelletizer roller, pelletizer rotor and pelletizer blades, etc.
In most pelletizer applications, the pelletizer unit does not exist alone, but needs to work with crushers, mixers, dryers, coolers, screening machines, packing scales, crumblers and other equipment, together to form a pelletizer line, or what we usually call feed mills, wood pellet processing plants, etc.
In order to use the new pelletizer machine correctly, reduce the pelletizer operator's use risk and the probability of mechanical damage due to improper operation, and increase the service life of the pelletizing machine, it is important to standardize the operation.
★Preparation before starting the pelletizer machine
★Operation steps of pelletizer machine operator
★Operation precautions of pelletizing machine
★Organize after shutdown the pelletizer machine
★Maintenance of pelletizer machine
★Prepare to boot
When the pelletizier machine operator is ready to start the machine, he must confirm the storage of each silo and the residual status of each process, understand the machine status and production plan, open each steam trap valve, and release the condensate in the steam for about two minutes.
★Start the pelletizer equipment
When the switch of the main engine is pressed, the granulator starts to run, but at this time, the pellet pressing machine has not really started up, and neither granulation nor oil can be added to wash the die. After the star-delta conversion of the main motor of the granulator, the ammeter After showing that the current is normal, you should put in some oily materials first, and rinse the ring die for about two minutes to heat the ring die.
It is very necessary to heat up the ring die. When starting to feed, the amount of feed should not exceed 20% of the production capacity of the pellet granulator. Prevent the pelletizer machine from feeding too much material in an instant, and the load suddenly increases, causing pelleting machine blockage or equipment damage. When the material is quenched and tempered, it feels tight and can be formed into a mass, and when it can disperse after letting go, close the feed door at this time and proceed to granulation.
Observe whether the current of the main engine is stable, and adjust the feeding amount and steam addition amount according to the production performance and current load of the pelletizer mill machine. The feeding amount must be gradually adjusted from low speed to high speed, and the amount of steam added should be adjusted according to the dry humidity of the material.
The pelletizer machine should avoid overloading, which can easily lead to the rupture of the ring die and the damage of the pelletizer extruder. Don't be careless and impatient when using the new die. It is necessary to run in moderately before the new mold reaches the best production capacity.
（1）Choose the power of the fish pellet feed machine according to the amount of bait. For fish ponds of 0.33-0.66 hectares (5-10 acres), the daily feeding amount is about 120 kg, and pellet feed machines with a power of about 1 kilowatt can be purchased; for fish ponds of 0.66-3.3 hectares, the average daily feeding amount is about For the size of 120-160 kg, the pellet feed machine with the power of 1-2 kW can be purchased; the fish pond of 3.3-6.6 hectares, the average daily feeding amount is about 600 -1200 kg, and the power of 2-4 kW can be purchased fish feed pellet making machine.
（2）Choose the specifications of the fish feed pelletizer machine according to the scale of breeding. For fish ponds with large aquaculture scale and a large proportion of bottom fish, hard pellet feed making machines can be used, otherwise soft pellet feed machines can be used. For fish ponds for breeding fish fry, small multi-functional feed pelletizer machines and crushing and screening machines can be used to obtain feeds of different specifications.
（3）Pay attention to inspection when purchasing. The shell paint should be complete and smooth, and there should be no defects such as cracks, peeling, bubbling, etc.; the gearbox should not have oil leakage; the mechanical transmission parts should have protective devices and overload protection devices, and they should be eye-catching. Lubrication, operation, rotation, safety and other signs; each fastener must not be loose; each adjustment handle and hand wheel should be flexible, light and reliable; electrical parts should be in good contact, reliable insulation, and no leakage.
（4）Turn on the power and run for 3-5 minutes, and observe whether the operation is stable, whether there are abnormal shocks, vibrations and heating, and whether the pointers of the ammeter and voltmeter are normal.
（5） Finally, don't forget to ask for the pelletizer product certificate, instruction manual and sales invoice.
There are mainly three types of commonly used fish pellet feed machines, namely soft pellet feed machines, pelletizer machines and extruder machines.
The soft fish pellet feed machine is the earliest and most common one with simple structure and low cost. It can adapt to a wide range of raw materials, and can be used with various formulations of concentrated materials (rice bran, bran, bean cake, fish meal, barley flour, etc.), coarse materials (rice straw, wheat straw, soybean straw and other crop straw powder), green materials (water float) The mixed raw materials of lotus, water peanut, water hyacinth and various vegetables, etc.) and various additives are processed into pellet feed for fish.
After the feed is processed by the soft pellet machine, the nutrient content remains unchanged, and it is suitable for feeding middle and lower fish. The productivity depends on the feed composition. If there are more coarse materials, the productivity will be lower. Nowadays, this kind of equipment is almost invisible in the market, and customers should mainly consider extruder and pelletizer.
Pelletizer machine, also called hard pellet feed machine, is a kind of rapid development and more applications in my country. The nutrient content and taste of the pellet feed processed by the feed pelletizer machine have been improved. It is mainly used to press raw materials with relatively low moisture content (below 13%). If the moisture content of the raw materials is greater than 17% to 18%, a paste will be produced, which will cause the mold hole to be blocked. Pay attention to it when using it. Hard pellet feed has a low moisture content and is convenient for storage, but does not float. It is suitable for herring, grass carp and carp.
After the feed is processed by the extruded feed pellet machine, the nutrient content and digestibility can be improved, and it is especially suitable for the physiological characteristics of short intestine and weak digestion of fish. It is also an ideal pellet feed for fishing. The extruded pellet feed can float on the water for 6 to 12 hours without loosening, which is convenient for fish to eat.
The above three types of feed pelletizer machines have their own advantages and disadvantages, so you should choose according to your actual situation and economic conditions when you buy. Generally, it should be considered from the following three aspects.
In 1900, the casting mode pelletizer machine began to be used. This equipment is composed of a pair of pressure rollers with the same shape. The two pressure rollers rotate relative to each other. Each pressure roller has a hemispherical pit. The installation accuracy of the pressure roller of this pelletizing equipment is required to be high to ensure that the hemispheres on the two pressure rollers can be well matched when the pressure roller is running, so that the material is compressed into spherical particles from top to bottom.
The pellets processed by this pelletizer equipment have low density and low strength. If the hemispheres on the two pressure rollers are not matched well, the shape of the processed particles will be defective. During this processing, the materials basically did not undergo chemical changes. This equipment has low productivity and high power consumption, so this processing technology has not been accepted in the feed processing industry. However, similar machinery can still be seen in other industries today.
Around 1910, the extruder pelletizer machine was born. The first commercial extrusion pellet machine was built by the United Kingdom in 1910. Developed by Sizer. The so-called commercial pelletizer extruder is a pelletizer machine accepted by people in the feed processing industry and put into production. Compared with the modern extrusion pellet machine, the pelletizing principle of the extrusion pelletizer machine developed in 1910 is the same as that of modern ones. The materials are forced forward by a spiral material conveyor and finally squeezed out of the die hole. Columnar pellets are formed, which are then cut into pellets by a rotary cutter.
The Schueler pellet machine is manufactured according to the compression method proposed by Schuyler in 1920. This pelletizer machine uses two gear-like rollers to squeeze the material from the discharge hole at the tooth root of the gear. Finally, It is cut to the desired length by the cutter inside the gear. Compared with the cast-mode pellet machine and the extrusion pellet machine, the Schueler pelletizer machine is easier to wear and has a higher cost of use.
（4）Still in 1920
In 1920, the first flat die pellet machine came out. This kind of machine is mainly composed of a roller rotating around a central axis and a horizontal fixed template, which has extrusion holes. With the rotation of the roller, the material is squeezed and forced through the extrusion hole to form a material strip, and then the cutting tool is rotated to cut it into a certain length of pellets.
The flat die pelletizer effectively improves the productivity of the pelletizer mill and reduces the mechanical wear. However, the linear velocity of the contact point between the flat die and the straight roller is different along the radial direction, which affects the uniform quality of the finished product and the uniform wear of the die roller. Therefore, some people turned their attention to the ring die pelletizer machine.
Almost at the same time, the first ring die pelletizer machine was also successfully developed. The ring die pellet making machine is mainly composed of a ring die with a die hole and a plurality of pressure rollers. In the beginning, the active roller (press roller) mode adopted by the ring die pellet granulator, after years of continuous improvement, gradually adopted the active ring die mode.
With the rotation of the ring die, the material is squeezed into the die hole, and then squeezed out of the die hole, and then cut into pellets of a certain length by the cutter outside the ring die.
（5）In 1931 and after
Foreign research on pelletizers started relatively early, and the ring die pelletizer was successfully developed by the American CPM company in 1931. In 1934, the company produced the first horizontal ring die pelletizer. Richi Machinery is the same technology used by the American CPM company. After the 1970s, many European countries have also researched and produced ring die pelletizers. Today, the United States, Canada and other countries with developed animal husbandry are still continuing to study feed pelletizers.
For the research of granulator, China started relatively late. China's first pelletizer machine was developed in the 1970s. This pelletizer was developed on the basis of gradually absorbing the pellet machine from UMT company in the United Kingdom. Nowadays, relying on its own advantages in the entire industry chain, it is technically comparable to the world, and its price has greatly reduced the cost of purchasers.
After the appearance of the ring die pelleting machine, the basic form of the pellet forming machine has not changed much, but the manufacturing level and technical performance have been greatly improved. It can be seen that the ring die pelletizer machine is currently the most ideal equipment for pelletizing, and it has been sought after by high-quality pelletizer machine manufacturers from all over the world.
