Forage harvesters can be implements attached to a tractor, [4] or they can be self-propelled units. In either configuration, they comprise a drum (cutterhead) or a flywheel [5] with a number of knives fixed to it that chops and blows the silage out of a chute of the harvester into a wagon that is either connected to the harvester or to another vehicle driving alongside.
Craigslist headquarters in the Inner Sunset District of San Francisco prior to 2010. The site serves more than 20 billion [17] page views per month, putting it in 72nd place overall among websites worldwide and 11th place overall among websites in the United States (per Alexa.com on June 28, 2016), with more than 49.4 million unique monthly visitors in the United States alone (per Compete.com ...
A small adjustable nozzle at the top, controlled by a handle at the base of the silo directs the silage to fall into the silo on the near, middle, or far side, to facilitate evenly layered loading. Once completely filled, the top of the exposed silage pile is covered with a large heavy sheet of silo plastic which seals out oxygen and permits ...
Silage gas contains nitric oxide (NO), which will react with oxygen (O 2) in the air to form nitrogen dioxide (NO 2), which is toxic. [16] Lack of oxygen inside the silo can cause asphyxiation. Molds that grow when air reaches cured silage can cause organic dust toxic syndrome. Collapsing silage from large bunker silos has caused deaths. [17]
The 1817 Boulton & Watt blowing engine, formerly used at the Netherton ironworks of M W Grazebrook, now preserved on the A38(M) in Birmingham, UK. Early steam prime movers were beam engines, firstly of the non-rotative (i.e. solely reciprocating) and later the rotative type (i.e. driving a flywheel).
Field corn is a North American term for maize (Zea mays) grown for livestock fodder (silage and meal), ethanol, cereal, and processed food products.The principal field corn varieties are dent corn, flint corn, flour corn (also known as soft corn) which includes blue corn (Zea mays amylacea), [1] and waxy corn.
It was founded in 1854 by the inventors Philander Higley Roots and Francis Marion Roots. It is notable for the Roots blower, a type of pump. [1] Today, Roots blowers are mainly used as air pumps in superchargers for internal combustion engines; they were first used in blast furnaces to blow combustion air to melt iron. [2]
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
