Technological Development

The impact crusher is a kind of new type high efficiency crushing equipment. It has the features of small volume, simple structure, and big reduction ratio, high production capacity, production size well-distributed; also have the selective crushing effect. It is promising equipment. But its biggest drawback is the hammer and the back plate particularly easy to wear, especially when crushing hard rock, wear and tear is more serious. Mainly focus on improvement of hammer and rotor structure, in order to facilitate the replacement board and hammer mounted card, counter-attack aircraft (the crushing chamber shaped) structure optimization? increasing energy efficiency.

Secondly, research and develop new kind hammer plate material which is high toughness, and increase productivity. In crusher, the high speed rotating hammer will impact and crush and grind the limestones. For the equipments in long working time is bearing the impact and friction of materials, rotor members are worn, deformation, damaged and will lose the normal work ability, which is inevitable.

If we don t do regularly rotor analysis, prediction and do planned life work maintenance and overhaul, eleven emergencies appear, these emergencies will cause severe losses that all production will stop, which is so serious to the enterprises. The main content of repairing and gradation on hammer crusher hammer are: hammer is the main work in hammer crusher parts.

Hammer dish is divided into several parts along the circumference and equipped with N hammers. Adjacent hammer and the hammer can do full circle swinging interlaced in 360 degrees. When the front edge of hammer are worn to the two-thirds of width, the hammer can be turned over to be used again. The worn hammer can do bead weld antifriction alloy and save a large amount of metal material consumption. With its high quality products, hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments. Aggregate crushers are used in mining, quarrying and recycling operations. Several types of crushers can perform this task including hammer mill, and gyratory crushers. An aggregate crusher can be relatively small, like the mobile units used for reclaiming recycled asphalt, or huge machines that can process thousands of tons of material to day. A screen keeps material inside the drum until the rotating hammers pulverize it into pieces of the desired size. These types of aggregate crushers are commonly used to produces crushed stone for landscaping or to process recycled asphalt. Hammer mills are sometimes known as impact crushers. Jaw crusher is the aggregate crushers that are most often employed in large mining or quarrying operations.

Crusher Sand Mechanism

Mechanism sand promotes the development of crusher With the continuous advancement of science and technology, industrial production is increasingly relying on mechanical efficiency and convenience, especially in the gravel production. The gravel aggregate is an inseparable part of the construction project, it promotes modern reinforced concrete buildings to erects, and the flat road to extend in all directions the sand and gravel industry has made tremendous contribution for the economic construction. The sand and gravel industry is a long history of industry, now, the sand and gravel industry has become one of the basic industries supporting the national modernization. The traditional way to produce sand and gravel is very backward, especially before the reform and opening up, China s economic development was lagging behind, economic policy was austerity, and the construction of infrastructure was in a phase of stagnation. In modern society, the pursuit of production efficiency asks people begin to increasingly focus on the benefits of sand maker in the gravel production.

The mechanism begins to be used instead of the traditional river sand sand by its advantages. Mechanism sand can achieve unified specifications according to different demands and avoid the waste so the market is very broad. In the last few years, due to the economic development destroyed ecological balance, the state vigorously promote environmental protection and ecological balance protection, environmental support policies on the sand and gravel industry greatly stimulates the development of mechanisms sand. The boom of the sand will drive the development of crusher market mechanism. From the development trend of industry, improve the performance and adaptability crusher of the working environment is a major trend. Under the situation of the state is vigorously promoting infrastructure construction, crusher industry in China should seize the broad market and improve their level, make good use of the opportunity to improve the ability of independent R & D and innovation so that improve the international competitiveness of crusher product.
