Because of many adverse conditions, such as high moisture content, high coal slime and high viscosity, the water and low heat value, it is difficult to be applied in the industry. Since the reform and open policy, the national economy has developed rapidly. Coal production has been the first in the world, at the same time. The situation of market also has changed greatly, the depth and extent of coal processing begins to develop rapidly. The output of coal slime obviously rises, the comprehensive utilization of coal slime has become the problem which is needed urgently.
Commodity price is influenced by various factors, and some of them are beyond expectations. Economic crisis, natural disasters are factors that we can't avoid. What we can do is to predict these factors as soon as possible, and prevent the potential damage in advance. In crushing machinery industry, it is steel that can affect crusher price to a great extent.
On Medicine, through biological engineering we can produce a lot of cheap drugs for control of human diseases, such as insulin, the interferon, growth hormone, hepatitis B vaccine, etc. The application of Biological engineering on food and light industry is also very wide. In 1983 the United States manufactured high fruit syrup with biological engineering which was used in the of making drinks, the annual output was as high as 6 million tons, so that the consumption of sucrose was cut in half. By biological engineering technology, breeding work has made very big change, such as transference the resistance gene to tobacco, has been developed new varieties of tobacco to prevent pests; The lower organisms of rhizobium nitrogen-fixing gene is transferred to higher crop of cell, so that they can make nitrogen fertilizer themselves,which has obtained some achievements.
The technical personnels of Hongxing Mining Machinery Co., LTD are aiming mainly at characteristics of the coal slime, they have designed and developed new rotary dryer. Through to the drying and production requirements of material and the reasonable design, the new rotary dryer can reduce energy consumption, conservation of resources, reduce the production cost, improve the market competitiveness of products.
