How to choose the dry granulating machine in your granular fertilizer making plants?

The following content shows the parts of double roller granulator with highlights design.

The working part of the double rollers pellet machine head: The transmission wheel is transmitted to the transmission roller shaft through the pin coupling. The synchronous operation of the pair of rollers is guaranteed by a pair of open gears. There are specific bearings on both sides of the active and passive shafts, which are composed of bearing frames and installed. on the rack.

Rack part: All the working bodies of the machine are all installed and fixed on the rack. The frame of the machine is made of medium carbon steel plate and channel steel welded, and through strict quality control and specific process requirements, to achieve the purpose of this machine, there are hoisting holes in the middle of the four corners of the frame to facilitate loading and unloading transportation.

Transmission connection part: The motor drives the pulley, the V-belt and the reducer to drive the machine head to work. In addition, the sprocket and the chain form the transmission chain and transmit it to the crushing and separation working part. Among them, the transmission reducer and the working part of the roller granulating equipment  are meshed with nylon pin couplings to transmit and drive.

The working part of crushing and separation: the material flows into the crushing chamber on the lower side after being squeezed by the rollers, and the pellets and the returning material can be separated by the rotation of the double-shaft mace.

The use and maintenance method of dry rolling granulator as following:

1. When using, it should be noted that there should be no hard objects such as stones and iron blocks in the raw materials. After more than ten shifts (8 hours for each shift), the rollers need to be disassembled, and high temperature resistant grease should be added to the bearings to make the rollers work. The double shaft extrusion granulator has the characterisctics of good performance, prolong bearing service life.

2. During granulation, it is strictly forbidden to contact the pressure roller and the template for idling.

3. If the particles are broken or not compacted, the crude fiber material formula should be reduced to less than 50%.

4. If there is no granulation and no material during granulation, the membrane plate should be removed, and after opening one by one, some fiber materials can be added appropriately to restart the granulation.

5. The tightness of the belt should be checked frequently, and the oil seal should be replaced in time if the gearbox is leaking oil.

How to solve the problem of manure pollution for 5000 pigs?

Image
A pig manure output is about 3 kg per day, and the annual fecal output of 5000 pigs is about 5475 tons. The 5000 pig factory suggests to purchase a small-scale production line with an annual output of 5000 tons of organic fertilizer. The annual profit is very considerable. Moreover, the pig manure in the pig house is gone, which can ensure the health of pigs, reduce the incidence of diseases and increase the marketing rate of pigs. For a rural pig farm with 5000 pigs on hand, anaerobic treatment mode or aerobic treatment mode should be considered before waste recycling. Aerobic treatment mode can produce more solid organic fertilizer resources, while anaerobic treatment mode can produce biogas resources and liquid organic fertilizer resources. Anaerobic fermentation needs to use biogas tank, although the state has supportive policies, aerobic fermentation is more appropriate. The main factors affecting the fermentation process are water content, carbon nitrogen ratio, pH value, ventil

What are the requirements of self-propelled tiller for organic manure fermentation site?

Image
1. The working site of using self propelled composting machine shall be smooth and solid, and there shall be no concave and convex surface greater than 50mm in the working area. 2. Strip stacking: the width can not be super wide, the height can be increased within 100mm, the length is not limited. 3. At both ends of the pile, there shall be no less than 10 meters of empty space for easy turning, and the pile spacing shall be at least 1 meter. 4. The  self-propelled composting turner with wheel s only a walking pile turning machine, and can not be used as a walking vehicle or a heavy vehicle. We need to master these methods when we use the organic fertilizer self-propelled stacking machine as following:  1. The airport ground of self-propelled turning heap needs to be smooth and solid, and there shall be no concave and convex surface greater than 50mm in the operating area. The length is not limited, and the width should ensure the rotation of the machine. 2. The width and height of th
