摘要:
A method of utilizing sewage sludge compost for mushroom growing and re-utilizing the used compost as livestock feed. During the use of compost for mushroom growing, lignin, cellulose, etc. of slight decomposability contained in the compost are decomposed and aroma suitable for livestock feed is imparted to the compost by the mushroom, thereby making the compost most suitable for livestock feed.
摘要:
A conveyor apparatus in which magnetic liquid is provided between a transfer track and a transfer object and a permanent magnet is fitted on the bottom of the transfer object to attract the magnetic liquid to move together with the transfer object thereby serving as a lubricant and permits the transfer object to move on the track afloat or buoyed-up by the magnetic liquid. An edge of a magnetic pole is shaped to have a loft angle in contact with the magnetic liquid to produce an upward component during its movement thereby increasing buoyancy and stability of the transfer object. Dust stir-up is precluded by virtue of the use of a magnetic liquid, as opposed to a conventional pressurized air support method.
