POTASH CRUSHER

Potash is the common name for various mined and manufactured salts that contain potassium in water-soluble form. In some rare cases, potash can be formed with traces of organic materials such as plant remains.
Potassium is the seventh most abundant element in the Earth's crust, and is the third major plant and crop nutrient after nitrogen and phosphate. About 93% of world potash consumption is used in fertilizers, with small amounts used in manufacturing soaps, glass, ceramics, chemical dyes, drugs, synthetic rubber, de-icing agents, water softeners and explosives. Other main potash fertilizer products include potassium sulfate (K2SO4) and potassium nitrate (KNO3).
Potash has been used since antiquity in the manufacture of glass, soap, and soil fertilizer. Potash is important for agriculture because it improves water retention, yield, nutrient value, taste, colour, texture and disease resistance of food crops. It has wide application to fruit and vegetables, rice, wheat and other grains, sugar, corn, soybeans, palm oil and cotton, all of which benefit from the nutrient’s quality enhancing properties.
Demand for food and animal feed has been on the rise since 2000. The U.S. Department of Agriculture’s Economic Research Service (ERS) attributes the trend to average annual population increases of 75 million people around the world. Geographically, economic growth in Asia, India, and Latin America greatly contributed to the increased use of potash-based fertilizer. Rising incomes in developing countries also was a factor in the growing potash and fertilizer use. With more money in the household budget, consumers added more meat and dairy products to their diets. This shift in eating patterns required more acres to be planted, more fertilizer to be applied and more animals to be fed – all requiring more potash.
After years of trending upward, fertilizer use slowed in 2008. The worldwide economic downturn is the primary reason for the declining fertilizer use, dropping prices and mounting inventories.
While about 150 countries use potash for their crops, it is produced in only about a dozen of them. World production totaled 36 million metric tons in 2008, according to the U.S. Geological Survey. Canada is the world’s leading producer, followed by Russia and Belarus; the United States ranks seventh. The most significant reserve of Canada's potash is located in the province of Saskatchewan and controlled by the Potash Corporation of Saskatchewan.
The world's largest consumers of potash are China, the United States, Brazil and India. Brazil imports 90% of the potash its needs.
Potash imports and exports are traditionally reported in "K2O equivalent", although fertilizer never contains potassium oxide, per se, because potassium oxide is caustic and so highly reactive that it must be stored under kerosene, as with metallic potassium.
In the beginning of the 20th century, potash deposits were found in the Dallol Depression in Musely and Crescent localities near the Ethiopean-Eritrean border. The estimated reserves are 173 and 12 million tonnes for the Musely and Crescent, respectively. The latter is particularly suitable for surface mining; it was explored in the 1960s but the works stopped due to the flood in 1967. Attempts to continue mining in the 1990s were halted by the Eritrean–Ethiopian War and have not resumed by 2009.
Potash prices have soared in recent years. What was once a commodity worth about $200 a tonne is expected in 2009 to reach $1,500 by 2020; Vancouver prices are US$872.50 per tonne in 2009, which is a record high.

Crushing Plant & Portable Crushing Plants
