A bale has an essential role from the farm to the factory. The cotton yield is calculated in terms of the number of bales. [2] Bale is a standard packaging method for cotton to avoid various hassles in handling, packing, and transportation. The bales also protect the lint from foreign contamination and make them readily identifiable. [3]
Due to their size and their weight, which can be a ton or more, large round bales require special transport and moving equipment. The most important tool for large round bale handling is the bale spear or spike, which is usually mounted on the back of a tractor or the front of a skid-steer. It is inserted into the approximate center of the ...
A quire of paper is a measure of paper quantity. The usual meaning is 25 sheets of the same size and quality: 1 ⁄ 20 of a ream of 500 sheets. Quires of 25 sheets are often used for machine-made paper, while quires of 24 sheets are often used for handmade or specialised paper of 480-sheet reams.
These are 20% protein, 20% oil and 3.5% starch. Fibers grow from the seed coat to form a boll of cotton lint. The boll is a protective fruit and when the plant is grown commercially, it is stripped from the seed by ginning and the lint is then processed into cotton fibre. For unit weight of fibre, about 1.6 units of seeds are produced.
Large bales come in two types: round and square. Large square bales, which can weigh up to 1,000 kilograms (2,200 lb), can be stacked and easily transported on trucks. Large round bales, which typically weigh 300 to 400 kilograms (660–880 lb), are more moisture-resistant and pack the hay more densely (especially at the center). Round bales ...
Current estimates for world production are about 25 million tonnes or 110 million bales annually, accounting for 2.5% of the world's arable land. India is the world's largest producer of cotton. The United States has been the largest exporter for many years. [3] Cotton ready for harvest in Andhra Pradesh, India.
Cotton is shipped to mills in large 500-pound bales. When the cotton comes out of a bale, it is all packed together and still contains vegetable matter. The bale is broken open using a machine with large spikes, called an opener. To fluff up the cotton and remove the vegetable matter, the cotton is sent through a picker or a similar machine.
The lint cleaners again use saws and grid bars, this time to separate immature seeds and any remaining foreign matter from the fibers. The bale press then compresses the cotton into bales for storage and shipping. Modern gins can process up to 15 tonnes (33,000 lb) of cotton per hour.
