How to effectively use waste straw?
Before the large-scale introduction of fertilizer equipment, when the rural autumn harvest, there will always be a lot of wheat and corn straw. These straws are burned by the villagers because they are not used. Generally, the straw can be burned for one afternoon. Rolling, the resulting smoke is harmful to human health, and this burning straw also pollutes the atmosphere. China’s agriculture can produce more than 700 million tons of straw per year. In order not to pollute the environment, there is now a technology to recycle straw. How can the straw be recycled and turned into waste?
With the development of society, the machinery industry has made rapid progress. The fertilizer equipment invented by people can use waste straw for high-quality fertilizer granulation, which solves the problem of waste straw polluting the environment. Here, I would like to introduce to you the granulation equipment that plays a major role in the granulation of waste straw—-disc granulator. The disc granulator is a type of granulator. The disc granulator is lined with high-strength FRP, which has the advantages of uniform granulation, high granulation rate, stable operation, sturdy and durable equipment and long service life. Very ideal granulation equipment.
The working principle of the disc granulator
Various dry powder materials are added from the top of the disc granulator, degassed, spirally pre-compressed and transported to the arc-shaped notches of the two rolls. The two rolls rotate at the same speed and in opposite directions to bite the material into the tank and carry out Forced compression, the pressure of the material after passing through the compression zone is gradually reduced, its surface tension and gravity make it naturally come out, break into the granulator and the granulator, trim, and then enter the vibrating screen for screening, and the qualified product passes through the disc. The granulator conveyor is sent to the finished product warehouse or directly packaged. The powdered sieve material is again sent back to the raw material warehouse through the feeding device for secondary rolling. The pressing force can be carried out by the hydraulic system according to the needs of the particle strength adjustment.
