rotary drum dryer is mainly composed of cylinder, under frame, feeding and discharging devices

rotary drum dryer is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover and so on. Rotary drier manufactured by victor machinery adopts new lifting plate, which is of functions like guiding, current-sharing, and material raising.the rotary drum dryer works with disc granulator in a complete whole organic fertilizer production line to produce bio organic fertilizer granules.the materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency. Our rotary drier is designed with the best working conditions, which enables it to save 10-15% of energy and increase 10-15% of productivity compared with common dryers.

 rotary drum dryer is widely used for drying materials in industries like cement, mine, building materials, chemistry, food and fertilizer, etc. This rotary drying machine comes with thermocouples on the feeding and discharging device to control the temperature. Thermometers are also adopted so as to better control the working temperature (generally 350-380°) of the rotary drier.

Brief introduction on working principle:

First step: connect the natural gas to the burner to have the hot heat,

Send the raw material by screw conveyor into the drum, there has fan it will

Absorb the heat into drum, the drum rotary with the heat and the materials for drying, after the moisture has out disposed ,the fan again send the dry materials into the dust collection machine(Shaq Dragon) for discharge. The drum dryer has continues drying function, and the dry effect is higher than other dryers.

Rotary dryer can reduce coal moisture from 40-50% to less than 5%

Rotary dryer can reduce coal moisture from 40-50% to less than 5%, fuel can be coal, natural gas, oil. rotary dryer consist of shell, front and rear supporting wheels, feeding and discharge device, gear device  and gear cap. Because of
the adoption of reasonable working parameters, rotary dryer, which used with rotary drum granulator to make up of a complete whole compound fertilizer production line,can save 10-15% energy and increase production by 10-15%,which is manufactured by victor machinery.the Rotary dryer’s heat source is a combustion apparatus.the rotary dryer adopts direct flow heating with heat source from firing unit. The material to be dried is pushed back immediately by spiral board after going in the shell from feeding tank or feeding chute. Because the drier is installed in an inclined position, material flows to the back end under gravity and rotation force. At the same time,the rotary dryer is lifted by board repeatedly and thrown down accordingly, which makes the material form an even curtain, so that the rotary dryer can exchange heat sufficiently with the heat flow.

New Organic Fertilizer granulator is the latest product of fertilizer machinery

new organic fertilizer granulator is the latest product of institute of fertilizer machinery with years of experience in organic fertilizer processing equipment design and development, which has won the national utility model patent.the new organic fertilizer pellet mill is used for granulation of fermented organic matter to break through conventional granulation process, Before te granulation, no need to dry the raw materials, raw materials and ingredients can be processed directly after smashing a spherical particle,the new organic fertilizer production line granulator can save large amounts of energy.Production of particles as spherical, organic content of up to 100%, granulation achieving pure organics, organic particles can be characteristic of the role must be able to inlay each other growing up, granulation without a bonding agent.Particle strong granulation to screening, reduced drying energy, raw materials and water included in 20%-40%.

the new organic fertilizer granulator machine is especially for granulating manure organic fertilizer granules. This new design type organic fertilizer granulator machine is developed and designed by our company engineer in recent two years.the new organic fertilizer granulator machinecan granulate all kinds of fermented organic materials like poultry manure straw meals,grass meals,bentonite,organic waste and so on .before granulating, the raw materials is not necessary to be dried because the raw materials water content for the new organic fertilizer granulator machine can be 30–55%,and can granulate crushed raw materials directly. 

The main working method of rotary granulator is aggregate wet granulation

The main working method of rotary granulator is aggregate wet granulation. Through a certain amount of water or steam, basically the fertilizer mixing wet in tube body after the full chemical reaction. Under a certain liquid conditions, in virtue of rotary exercise of the rotating cylinder, so that material particles have a extrusion stress, reunite to ball.the rotary fertilizer granulator is one of the key fertilizer production line equipment of compound fertilizer industry, and this type granulator is suitable for cold and hot granulation and high and low concentration of compound fertilizer production on a large scale. This rotary granulator machine cylinder, with a special jointing sheet lined with or acid stainless steel lining board, has realized automatic scar removal to take off the tumor, and canceled the traditional scraper. The rotary granulator machine has the features of high strength into the ball, good appearance and quality, corrosion resistance, resistance to wear, low-energy consumption, long service life, convenient operation and maintenance, etc.

The main features of Rotary Granulator:
(1)Rate of ball-becoming up to 70%, have a small amount of returned material, expected, small granularity of returned material, can be re-granulation.
(2)Steam heating, improve material’s temperature, so that have lower moisture when material change into the ball, improve dryness efficiency.
(3)the rotary granulator use rubber plastic for lining, raw materials difficult to stick cylinder, and played the role of anti-corrosion, keep warm.
(4)the rotary granulator has high yield, little power consumption, low maintenance costs.

The biological organic fertilizer granulator overcome problems of the existing biological fertilizer granulator

The biological organic fertilizer granulator overcome problems of the existing biological fertilizer granulator, such as high-temperature sterilization, bad discharging and dry hard. the bio fertilizer pellet mill can protect bacteria under normal temperature, with reasonable design, simple structure, lower final product moisture, easy to dry, at same time could produce feed, fills the market blank of multi-usage in field of granulating machine.

Are you looking for urea-based compound fertilizer equipment?

Are you looking for urea-based compound fertilizer granulator equipment?
Are you going to upgrade your existing fertilizer equipment?
If your answer is YES, please don’t hesitate to contact us. We can provide not only high quality urea granulation process equipment, but also upgrade services for organic fertilizer production equipment.We are a urea granulation machine manufacturer in China. In addition to urea-based compound fertilizer production line, we can also provide many other types of fertilizer equipment, such as NPK compound fertilizer equipment, organic fertilizer equipment, to name a few.

This type of compound fertilizer rotary drum granulator equipment utilizes melted-urea as the main nitrogen source. During granulation process of fertilizer production, melted-urea will be mixed with other raw materials by coating on these materials.As a matter of fact, melted-urea has several functions during fertilizer production. It firstly functions as a kind of raw material, and then functions as a liquid to participate in granulating process, and finally produces heat which makes drying process easy.The primary component of our urea granulation process equipment is a spray granulation dryer.
