Mining machinery industry to enhance innovation capability
Application and development of mining machinery and infrastructure are inextricably linked, in the near future there is a great development, but it seems a lot of people in the
industry, I had this in the mining machinery stone feeding machine industry, the technological level to have great with foreign differences with foreign behind many of our domestic mining machinery
technology currently used mostly in the 1980s when the technology came from abroad, in China, the share of the domestic coal vibrating screen machinery also simply accounted for less than 80%,
In mostly imported products, big, fine, sharp and strong sets of products, such as crushers, large high-efficiency separation equipment, full-face joint boring machine, coal
mining, grinding equipment and other products.
Mining machinery industry, science and technology is not strong, the reform and opening up, mining machinery sector has been in the market for technology to improve the
technical level of the main ways to view the world from a comprehensive course of development of each country, the main products are stand-alone devices to stand-alone to
complete the process in the evolution of the process equipment, mining machinery manufacturing country generally completed only complete stand-alone products into production, as
use of the product by the person to be responsible for the process, the single product of the process plant is also completed by professionals, which resulting in equipment
manufacture and use of equipment, the gap between, experts believe that when mining machinery manufacturing sectors and enterprises process design is weak in the case, except in
the case of their own conditions as well organize forces into the role, should be taken abroad domestic construction companies and different forms of joint professional design
institutes, including the formation of groups, unions, the introduction of talent, technology and other methods to fight in a joint project on the design methods, the first
intervention to improve and achieve win-win situation.
In addition, experts suggest, mining machinery industry is not applied technology research data and databases, you can not convince customers use the company's products and
processes, let alone truly innovative application of technology.

Impact hammer crusher basic structure to determine the parameters
1 the diameter and length of the rotor
The diameter of the rotor body and maximum feed size information. According to the impact theory, particle size and feed hammer proportional to the mass, and with the hammer
effectively combat height (ie the height of the rotor body exposed hammer) are closely related. In addition, taking into account the impact hammer crusher machine work process there is
a certain role when rolling, turning their anger must have sufficient capacity, which requires the diameter of the rotor body with feed particle size increases.
Typically, the diameter of the rotor body and the ratio of the maximum feed size is 2 ^ -4, take small mainframe. The length of the rotor is taken according to the production
capacity of a given size.
Hammerhead
a. hammerhead hammerhead shape and the height of the rotor is exposed h.
Design, hammer face should in principle be the rotation axis of the rotor in order to achieve a positive impact on the material hammer. Taking into account the wear compensation
or hammer weight restrictions, a slight deviation. Hammerhead ends arc surface design should consider the introduction of bite angle a. This paper recommends a 5-100. Too large
bite angle so that the hammer premature wear and reduce the life of the hammer. The arc length is mainly based on the type of hammer weight required strength corresponding
hammer shaft diameter, and take an arm fixed thick. Hammer shaft and arm strength assessment can hammer in working condition in equilibrium when the force is calculated, and
when working with hammer centrifugal force as the payload checking.
Hammerhead exposed rotor body height h that is highly effective in combating the hammer. From the point of impact mining screen effects and hope h large production capacity, especially for
bulk materials, to achieve the desired impact, h is bound to large, in theory, if the force of the impact gob gob right through the center of gravity. Then shocks the best
results. Consideration to the structural design is reasonable, and the power consumption increases, the person must be properly increased. At the same time people can not be too
small, too small h increased the hammer on the material increases the abrasive cutting, it will affect the handling capacity of the crusher exacerbated hammer wear.
