Customer Guide Of Pellet Press For Sale
How a pellet press works? The working principle of the animal feed pellet press and the wood pellet mill granulator is based on the working principle of the ring die pellet pressing machine. However, due to the different materials to be pressed, there are differences in the specific equipment configuration, so here, RICHI explaines the working principle of the two types of pellet press equipment separately.
（1）How does a feed pellet press work？
The ring die feed pellet press machine is used to process various animal and aquatic feeds. It is mainly composed of feeding, mixing, pelleting, transmission and lubrication systems. The working process is to require a mixed powder with a moisture content of not more than 15%, enter the feed auger from the hopper, adjust the speed of the stepless speed regulation motor to obtain a suitable material flow, and then enter the agitator, stir and steam through the stirring rod mixing for conditioning, if you need to add molasses or fat, also add it from the mixing drum with steam for conditioning, (the addition of fat is generally not more than 3%, otherwise it will be difficult to form), after conditioning, the temperature of the mixed powder can reach 64～ 85°C, humidity of 14～l 6%. Then pass through the chute through the iron suction device to remove the iron impurities mixed in the powder, and finally enter the pressing chamber for granulation.
Powder feed is a loose body composed of dispersed particles with fluidity. Under the action of squeezing force, the gas between the powder particles continuously escapes, and the gap becomes smaller, the bonding force between the powder particles increases, and the protein in the feed And sugar is plasticized by heating, starch is also partially gelatinized, and water vapor acts as a binding agent, and the final feed is pressed into pellets with a certain density and strength. It is this extrusion thermoplastic process that makes the ring die granulator has many advantages. (Below is the delivery picture of chicken feed pellet press for sale Australia)
（2）How does a wood pellet press work?
The wood pellet press can be used to compress various biomass raw materials, agricultural and forestry waste, urban waste, organic fertilizer, waste tires, organic plastics and other pellets. The wood pellet pressing machine is operated in direct connection with a motor. The motor is connected to the shaft of the reducer through a gear coupling. After a 90°change of direction, the horizontal motor drives the vertical casting hollow transfer spindle, and the spindle drives the roller to roll the die. The inner surface completes the pressing process.
When working, the biomass wood material falls vertically from the feed inlet, and the material is continuously and evenly distributed on the surface of the mold cavity through the rotation of the pressure roller (the contact surface of the pressure roller and the pressing die), and the powdery material is crushed by the pressure roller holes through the mold (holes evenly distributed on the inner surface of the die). In this process, the material is subjected to high pressure and high temperature to produce physical changes or appropriate chemical changes (according to the material), which promotes the powdery material to form a continuously elongated cylindrical solid body, and then the pellets are cut by a knife and discharged from the discharge port. The pressing process of the pellets is completed. (Below is the delivery picture of cattle feed pellet press for sale South Africa)

With the rapid development of feed, biomass energy, organic fertilizer, chemical industry and other industries, the market demand for pellet mills is also increasing year by year. At present, most of the pellet press manufacturers are small and medium-sized, and the production technology is also at the stage of gradual maturity, and the product quality of the pellet press is also uneven. Therefore, you must pay attention to a few points when choosing a pellet press manufacturer, because after all, you are not buying a small item, so you must be cautious when buying equipment. (Below is the testing picture of cat litter pellet press for sale UK)
- First of all, we must inspect several pellet making machine manufacturers, and investigate the strength, reputation, scale, etc. of the pellet mill manufacturer in all aspects.
- Try to visit the production plant of the pellet press manufacturer as much as possible, and inspect the company's product quality, production technology, technical level, and production maturity. If possible, it is best to let the manufacturer of pellet press take the customer to visit the production site they make for the customer, because the user's on-site speaking is authoritative and convincing.
- Choose the appropriate equipment according to the customer's own site conditions and planned output. In addition, if the equipment should fail during operation, how to solve it, you should have a clear after-sales plan with the manufacturer.
- When signing the order contract with the pellet press manufacturer, you should carefully read the order contract. If you find any omissions, you should add it in time to avoid unnecessary economic disputes after signing the contract.
- The pellet press manufacturer is providing customers with on-site installation services. The company will send technical service personnel to participate in the unpacking acceptance and guide the installation and commissioning work until the equipment is operating normally, and provide corresponding technical training services.
- Finally, it is necessary to explain that customers should pay special attention when choosing equipment, and determine those companies that have entities and which are non-physical companies, so that customers can avoid detours when purchasing equipment and avoid unnecessary economic losses.
In recent years, the demand for pellets in many industries can be said to have skyrocketed. Pellet press machines have also become a trend in pellet processing. Under such fierce demand, more and more pellet factories have sprung up and want to seize the market. This is undoubtedly difficult for small-scale production that not only needs to ensure investment budget, but also to ensure stable output. Therefore, these customers must purchase equipment with relatively strong granulating ability from a large number of small pellet press granulator equipment. Ensure that you can achieve value for money. In order to better help our customers to purchase, we will give a better solution for this problem, and you can refer to it. The selection of the small pellet press machine is very important, and only the right equipment can be worth the money! (Below is the delivery picture of wood pellet press machine for sale Germany)

Attention points for operation
Note: When operating, not only should the safety attention points be strictly followed, but also the safety specifications and variety regulations for protection against accident enacted by the owner's enterprise need to be obeyed.
- Pay attention to the place where dangerous marks are attached.
- The safety protection devices can never be dismounted, covered or overlapped at will.
Preparation work
Prior to start, the following work should be done:
- Open the main door and its sided protection guard;
- Clean the pelleting chamber, check the feeder and conditioner;
- Check the installation condition for rind die, and check the proper adjustment for press rollers.
- Check and adjust the intervals between the pellet cutting knives and outer surface of ring die;
- Fill lubricating oil;
- Check the steam system. The delivery pressure should be within 0.7-1.0Mpa and the working pressure should be between 0.1-0.4Mpa.
Pelleting operation
★Start up
Following work should be prepared before startup:
- Open the front door;
- Clean the pelleting chamber, check the feeder and conditioner;
- Check the installation condition for ring die and the proper adjustment for press rollers. Pay attention to the gap between press rollers and ring die;
- Fill lubricating oil;
- Start up the feeder motors for feeder and the conditioner without load to check if the rotation direction is correct and there is any noise; and then shut them down when the feeder operates at low speed;
- Start up the motor of cooling system and the main motor. Firstly check and ensure that all the pellet press components are operating correctly; check and ensure the ring die rotates clockwise from front view. Then inspect the contact condition between the press rollers and the inner surface of pellet pressing die, which should rotate smoothly;
- Check the steam system. The pressure for the steam enters conditioner should be 0.1~0.4MPa. If there exist jacket, the steam pressure enters the jacket should be within 0.1MPa.
★Pelleting
To start up a new pellet press or the pellet pressing machine with new installed pellet press dry pressing die, the following procedures should be followed:
- Start up the motor of cooling system and the main motor of the pellet press mill.
- Feed certain amount of oily coarse mash to the inlet of the pellet pressing mill manually, and continue feeding until feed pellet is formed. This is the primary lubrication for the ring die before normal production.
- Start up the main motor of conditioner.
- Start up the feeder motor, adjust the frequency converter to low frequency and let the feed enters conditioner slowly. Do not add any steam in the beginning of pelleting. Increase the feeding speed slowly according to the current of main motor.
- Open the steam valve a little, then increase the feeding rate until the pointer of ammeter is falling; when the ammeter`s pointer of the main motor reaches the normal load, add steam amount to allow the ammeter`s pointer to fall back. Repeat this procedure until the maximum output and the best quality of pellet are obtained under the rated load.
- See pellet pressing process. The feeding amount and steam supply are different depending on the different types of ring dies and formulas, which results different pellet qualities. So that the pellet press operator should be rick in operating experience.
★ Shutdown
The shutdown procedures of pellet press machine are described below:
- Turn off the steam control valve of pellet press equipment.
- Cut off the feeder motor.
- Shutdown the conditioner motor.
- Keep the pelleting machine running until no pellet is produced.
- If the machine needs certain time to be stopped, for instance, during the end of working day, oily mash material can be fed into the manual-feeding inlet after working until the pellet is formed. As such, it is convenient for the ring die to start up next time.
- Shut down the motor of cooling system and the main motor of pellet press mill when it stopped extruding oily pellet.
In order to ensure normal and safe operation, the following safety countermeasures should be obeyed.
- Overload protective device
This pellet processing machine is equipped with an overload protective device associated with shear pin and limit switch on the main shaft end. When hard impurities enters the pelleting chamber or when the material flow rate is too high with unstable steam flow, the pressure between rollers and pellet press ring die will exceed the normal working pressure. The pellet press roller will drive main shaft to rotate since rollers are installed on the main shaft and the ring die is installed on the rotor. When the torque of the main shaft exceeds the normal design value, shear force on the safety pin exceeds its limit; the shear pin is sheared off. At this time, limit switch stops the motor of pellet press mill and shutdown the machine.
- Pneumatic emergency discharge
A by-pass is provided at the conical feeding inlet. When the materials enters ring die too fast, it will cause accumulation in the pelleting chamber and increase the load of motor. Under such condition, the by-pass will be automatically opened via the pneumatic system, and the feed will be discharged through the by-pass. When the motor load returns normal, the by-pass will be closed automatically and the whole system will continue operating normally.
- Safety switch of main door access
For the safety consideration, the limit switch will cut the power supply and stop the machine from running when the main access pellet press door is opened.
- Gearbox cooling system
Refer to the operation manual of cooling system for further information.
- Magnetic separating device
In order to ensure the cleanness and safety of gearbox, magnetic separating device is located under the gearbox, which can prevent the effect of moving components generated by the scrap iron impurities in lubrication system, and increase the service life for gear, shaft and seals.
The correct gap adjustment of press roller is very important, it concerns to whether the pellet pressing machine can function normally and the service life of pellet pressing roller and pellet pressing ring die. Generally speaking, the gap in press rollers should be controlled within 0.2 ~ 0.5mm. At this time, the roller can only touch the high spots of ring die when the ring die is running at a low speed.
Adjustment procedures:
- Loosen the lock bolt of front support assembly.
- Adjust the adjusting screw to make the roller move closer to the ring die counterclockwise. In the meanwhile, runt the ring die and roller for one circle. It is better to make the highest spot of inner surface of ring die contacts with that of the outer surface of press roller slightly.
- If the adjusting screw has reached its limited position during adjustment, but the gap between roller and ring die is not adjusted properly yet. It is necessary to dismount the adjustor, which is 5 in Fig.5-5 (a), turn it to another position, re-install and continue the adjustment.
- Adjust another roller by following the same procedure.
- Fasten the lock bolt of press roller.
Suggestion:
The press rollers are to be adjusted in accordance with materials. For instance, the gap between the roller and ring die can be slightly larger when the material has high content of corn or easy to be pressed.
