Problems and Solving Methods in Iron Aggregate

Many mineral processing plants in our country are at the edge of low profits and losses for reason of laggard ore beneficiation process, old rough equipment, small-scale enterprises etc. . Since 2003, China’s iron and steel sales has gradually increased,the demand for iron ore powder have also rise with it.As the demand increased, mineral processing plants of different levels came into being. In early 2005, being restricted by State macro-control restrictions on steel, price of iron ore powder declined sharply. Many mineral processing plants in our country are at the edge of low profits and losses for reason of laggard beneficiation process, old rough equipment, small-scale enterprises etc. How to make the development of such enterprises profitable, competitive and mineral processing plant is an important topic facing leaders.

Under the premise of years’ research on mineral processing equipment design, manufacturing beneficiation products, Henan Gongyi Fuwei Heavy Machinery Factory, summed up a complete program to improve product quality, reduce production costs and improve economic efficiency. Existing backward mineral processing plants, through the transformation of technology and equipment, the quality of its products and production costs, can reach domestic advanced level. After analysis, backward mineral processing plants have following issues should be addressed: 5mm down to 10mm, fine crusher broken one tons of ore need to power 5KWh. Replaced before the fine grinding of the ore crushing equipment for fine crushing, crushing and grinding so the two systems of 1 ton of ore can be reduced power consumption 7KWh. Before the fine grinding and crushing equipment, hammer lining consumption consumption costs, it is necessary to clear the ball and the ball is lower than the consumption of the cost of lining. A mineral processing plant with annual treatment capacity of 100,000 ton, may save electricity and material consumption of 400,000 Yuan if adopting advanced technology in technique process of crushing and grinding.

Problems existing in raw materials crushing and grinding system

Small-scale mineral processing plant before the broken ore particle siz is, about 25mm, which makes grinding efficiency decline significantly. Because the mill is a grinding equipment, as a result of the rough mill broken inefficient, when the 25 millimeters (mm) of the ore, grinding to 80 microns (um) the following at the time of grinding efficiency is very low.

Hammerhead and the lining of the consumption of 1 ton of ore need to 1 yuan as much as 1 ton of ore broken the power consumption needs 7KWH. Recommended to the user where they wear a piece of low consumption, the use of long, high output, nesting size stability, and power consumption of the energy-saving small cone bearings broke, power consumption can drive by the other minor 7KWh / tons of ore, down to 5KW / tons of ore. Lining the use of consumable materials cycle, from one week to six months can be broken ore consumption of 1 ton liner, wear-resistant steel hammer, etc. 0.2 kilograms / tons of ore around, fell to 0.01 kilograms / tons of ore, a decrease of nearly 20 times.
