As a leading manufacturer and supplier of pellet mills in China, GEMCO machinery has many significant advantages compared with the pellets processing machines of other manufacturers.

1. Transmission structure: GEMCO pellet mills adopt the latest advanced technology.

Advantages	GEMCO	Machines of Other Manufacturers
	Reduction gear	Bevel gear
	1.low noise2.rotating both forward and reverse3.gear has long service life	1.low investment2. easy maintenance

2. Raw materials of key components

GEMCO dies and main axis are made of 40Cr, while these of other manufacturers are made of 45# steel.

	40Cr/4Cr13	45# steel
Advantages	1. high content of 40Cr, more wear-resisting2. forging materials, and their mechanics performance has been improved	1. low intensity2. poor abrasion resistance

3. Heat treatment: The dies, main axis, and rollers of GEMCO are processed by vacuum treatment, while other manufacturers treat these components via carburizing and quenching. Consequently, GEMCO machines are more superior in mold hardness, wear resistance, and service life.

	vacuum heating treatment	carburizing & quenching
Advantages	1. no damage to the surface quality of key components2. cause tiny deformation of components	1. the hardness layer is thin, and the die only has short service life2. cause large deformation of components

4. Components Sealing

	GEMCO	Machines of Other Manufacturers
Common Components	both ends of the bearing are sealed	only one end of the roller bearing is sealed
Plastic Components	mechanical seal and oil seal effectively solve the problem of plastic’s electrostatic adsorption	no similar components

5. Hopper Seal: The feed hopper and discharging hopper are made of galvanized sheet, which avoids corrosion and prolongs its service life.

Features	GEMCO Hopper	Hopper of Other Manufacturers
	The whole hopper itself adopts sheet metal edge and pressing side structure, which is solid and reliable	It adopts the welding structure, which is loose and easy to break

6. Fastening Details: Adjust properly the space between the die and the rollers, which ensures that screw thread has no deformation or damage.

Packaging: GEMCO adopts the professional fumigation-free packing board, which leaves out fumigation in export. Besides, GEMCO machines are wrapped in plastic film to avoid corrosion in transport.

Packaging	GEMCO	Other Manufactureres
First step: Wrap the machine and its components in plastic film to make it moistureproof.
Second step: Fix well every component separately.
Third step: Sealing.

Maintenance of Pellet Mill

GEMCO pellet mill is characterized by high efficiency, large output capacity, low power consumption, and gear transmission structure that has long service life.

Once you have purchased your desirable pellet mill, it is proper maintenance that will make sure that it works as you’ve required. The key areas of maintenance are grease, oil, gearbox, main axis, and roller and die condition.

You should always keep in mind that when making wood pellets and operating wood pellet machine, the temperatures you are dealing with will be higher than other pellet mills. Therefore, this means that you need to use higher quality oils in the gearbox and also higher quality grease in the rollers and die. Serious damage can be done to the gear box if the condition of the oil and level of oil is not given the attention it deserves. Likewise for the grease in the rollers and the bearings on the drive shaft for the die. Extreme temperature grease is required and in some cases automated grease systems are used to make sure the rollers are always properly greased.

NO.	Lubrication part	Oil type	Period of lubrication	Period of oil change
1	roller	lithium base grease	twice per shift
2	main axis	lithium base grease	once per shift
3	gear box	hypoid gear oil	up to the set site at the first time	six months

1. Grinding before use. Before initial operation, make sure the gearbox is added with oil and bearings are properly lubricated according to the above chart. Because the mould pinch roller of pellet mills is mostly a heat treatment, after workstages of planning, drilling, milling, and quenching. There are probably many burr inner bore or surface, so a new pellet mill before using must be reasonably ground fully.
2. Before starting the machine, check whether the roller cover bolts become flexible, to prevent nut from falling down into the material, which cause the damage accident of compression roller.
3. Only after feeding you can start the machine, operating without raw material is forbidden. When the materials pressing is coming to an end, put a little bran mixed with edible oil in the machine and close down after suppression of 20-50 seconds, make die hole full of fuel, so that next time feed pellet mill can commissioning run as soon as possible, this can both maintain mold and save time. Loose pressure wheel to adjust screw and remove residual material after closing down.
4. You should never touch the pressing roller and die with hands or metal tools. You can use crabstick to stir when necessary.
5. Monthly check whether the electric equipment is in good condition or whether the wire is aged.
6. Use the pellet mill with clutch, before starting the diesel engine, make clutch separated. After starting the diesel engine, make clutch close slowly, and often check tightness of leather belt, check belt to prevent lower output, belt skid.
7. If you find clamping and unusual noise, you should stop the machine immediately. Restart the pellet mill after solving the problem.
8. Corrosion should avoid. As the dies are made of carbon steel, and during processing heat is produced and moisture is released from the raw material. Once the pellet mill has stopped processing and there is no material flow this moisture will start the attack the surface of the metal. Basically it will start to make the surface of the holes rough and this can lead to frequent blockages. Sand, oil and bran can be used.
