Sand Production Line, also known as sand making line, is mainly composed of jaw crusher, vertical shaft impact crusher (sand making machine), vibrating screen, sand washing machine and conveyor belt. Considering the situation of the decreasing natural sand, Henan Hongxing has developed series of sand making machine which are dedicated to the production of artificial sand, and the machine has the characteristics of good grain shape, little attrition, high into the sand, adjustable fineness modulus, low cost, etc. Sand making machine is more suitable for crushing materials of high hardness such as granite, basalt and so on. When producing sand and gravel production, it necessary to reasonably set the sand making production line. Experts give the following description on how to scientific and rational allocation of the following described line. Firstly, the stone materials are evenly conveyed to jaw crusher by vibrating feeder for a coarse crushing, the coarse crushing materials will feed into sand making machine for further crushing.

Then the crushed materials can be transported to the vibrating screen for screening. The finished product reaching the requiring size will be conveyed into the sand washing machine for washing, the washed product will output by the conveyor, which is the final finished product; The finished product not reaching the size will return to re-processing requiring from the vibrating screen, which forming a closed loop many times. The size of the final finished product can be combined and graded according to users. The general research institute of Henan Hongxing Machinery is the primary R & D department for technical research and technical management. It is responsible for developing all products, conducting forefront technical research on new products and setting standards; researching impact, noise, vibration, hydraulic technology, power matching and energy saving, new materialsand control systems, creating innovative technologies and conceptive products and building up a network-based special and generalized platform for experiments and tests so as to share general experiment and test results.

Coal Production

Posted by John Sommers on 13th December 2016 in General

Over 6185 million tonnes (Mt) of hard coal is currently produced worldwide and 1042 Mt of brown coal/dates. The largest coal producing countries are not confined to one region the top five hard coal producers are China, the USA, India, Australia and South Africa. Much of global coal production is used in the country in which it was produced; only around 15% of hard coal production is destined for the international coal market. It is said that the backward coal production will be phased out continually. In 2012, there will be reformation to reduce the number of small scope coal companies, expand and ensure the dominant position of large-scale coal enterprises.

Besides eliminating, the most important of this reformation is to ensure coal production. Therefore, the use of modern coal mining equipment is urgently needed. The twelfth-five year is key period of the overall construction to accelerate the reform and opening up and speed up the transformation of economic growth. The rapid development of industrialization, urbanization and agricultural modernization presents a rigid upward trend of the demand for mineral resources; the international political and economic situation is complex and changeable; in order to protect national economic security, geological prospecting work seems more urgent and more important than any period. We know that the most critical part of the coal mining is coal crushing.

The broken degree will directamente determines the utilization of coal. Kaihan Krippendorff contributes greatly to this topic. Therefore, choose a large, scientific and technological coal crusher will be the critical matter for coal enterprises to improve production. As technology continues to progress, some enterprises began to take great pains in the coal crusher and developed a series of new types of equipment. For example, domestic professional mining machinery manufacturer, Zhengzhou network Star Technology Co., Ltd. launched the coal pulverizer, raw coal ring hammer crusher, fine coal reversible crusher and other equipment which used the introduction of advanced technologies on the basis of the original crusher. Those achievements have produced a modern coal crushing equipment successfully. Automated operations reduced the investment of man force and material costs to a large degree. It is relatively in accordance with the requirements of large-scale company’s coal production. It is reported that these devices from Zhengzhou Red Star are Argentine as The only weapon to improve coal crushing efficiency by most of Shanxi coal enterprises. The coal resource is a non-renewable resource. Changing the backward mode of production and eliminating backward production capacity are the important methods to use coal in high efficiency. In the current case of rapid development of technology, the application of modern crushing equipment is the key to increase coal production levels. With the support of the new mode of production, China s coal industry will achieve sound and rapid development in the next few years. As the vanguard in machinery industry, Hongxing machine spends years in development and innovation and constantly develop new products, opening new markets to meet the production requirements of the mineral resources.
