â—The fineness of processing strength reaches 1-74um, and the particle size distribution is narrow and there is no large particle;
â— Materials collide with each other for crushing, can process Mohs hardness 1-10 materials, wear is small, the product no iron pollution;
â— Reasonable cooling flow field, due to the sharp expansion of air flow in the crushing process, the air flow temperature is reduced, so it is particularly suitable for the processing of heat sensitive, low melting point materials;
â— Optimize the structure of the equipment, improve the performance of the equipment, can be effective dispersion and dissociation of agglomerative ultra-fine powder, polymer;
â— Original collection flow field technology, can obtain good crushing efficiency and strict particle size cloth, crushing particle size can be arbitrarily controlled between 1-74um, very fine up to sub-micron level, small material loss, can realize the crushing cavity material basically completely crushed, little participation, equipment wall without dead Angle, easy cleaning, fully in line with GMP standards;
â— Original special jet and split flow field technology, suitable for the processing of dry adhesive materials;
â— Can be mixed and crushed several kinds of materials, and has a good mixing function;
â— Fully sealed negative pressure operation, no environmental pollution.

After the domestic crane industry experienced a sharp drop in sales at the beginning of this year, sales and sales revenues rebounded from the previous year since March. The analysis of monthly data of 6 companies in the industry shows that from March to May this year, the sales volume and sales revenue of the industry increased sharply year-on-year. However, in June, it suddenly fell sharply. The sales and sales revenue decreased by nearly 16% year-on-year. At the end of July, the display of industry statements was again unexpected, with the year-on-year growth of the above two figures rising by 33%. As the crane industry was relatively lax by the macro-control, the macro-control started in April 2004 only affected the crane industry in July, resulting in a sharp drop in industry sales during the month, resulting in a lower base, which resulted in sales in July 2005. The increase was significant.
For a long time, under the environment of rapid growth and relatively stable competition in the domestic crane industry, the tightening of macroeconomic regulation and control last year has spurred the domestic crane industry to show a polarized development trend different from other sub-sectors of construction machinery:
First, the large tonnage products are gradually serialized. Since the rapid development since 2002, Xugong, Xuzhong and other powerful enterprises have achieved rapid expansion of production capacity and achieved major breakthroughs in the development of high-tech products. Domestic engineering cranes are all-terrain cranes and large tonnages. Substantial progress has been made in products such as truck cranes and crawler cranes.
The crane industry presents a gratifying competitive landscape: First, Xugong and Xuzhong launched a series of 100-ton-class all-terrain cranes with a capacity of 130 tons, 160 tons and 200 tons, and sold them one after another, followed by other manufacturers in the industry. Started investing funds and research and development to tackle the high-end technology of the whole road surface; on the competition of large-tonnage crawler cranes, following the heavy-duty 150-ton product launched by Xu Zhong, Xu Zhong developed another 300-ton class, Fusui, Puyi and Large-tonnage crawler cranes such as 250-ton and 200-ton have been developed successively, and crawler-type large-tonnage cranes have begun to form relatively complete profiles. The high-end products of the industry gradually realize the spectrum and serialization, which indicates that the high-tonnage products of China's crane industry have begun to enter a more mature stage of development, and gradually replaced high-end imported equipment has become a reality.
Second, the competition between new and medium-end new products is heating up. On the one hand, high-tech products such as all-terrain cranes have played a powerful role in promoting the development of the entire industry and even improving the level of China's infrastructure. On the other hand, the competition for low-end and new-end products caused by the sharp contraction in market demand has entered a white-hot state. Unlike the loader industry, manufacturers in the crane industry are extremely cautious about price wars, and the strategy of dealing with competition is cut from new products, and strives to introduce differentiated products in the early stage. Since July 2004, the construction crane industry has recently launched and first sold 17 products. If the old products are improved, they will reach nearly 30. Almost every family has new products, and each of the powerful manufacturers currently has several projects under intense development.
A notable feature of this new product is the full development or cater to the short- and medium-term demand of the market, further subdividing the blank market between 25 tons and 35 tons, between 65 tons and 80 tons, and launching 30 tons and 70 tons of products. In order to show the difference and attract the attention of the market, the product model labeling began to appear 26, 17, and 52 models that are different from the industry routines; the highlight of the local highlights is another performance of the "short-line" new product, targeting the user to hang the crane Demand increased arm length, such as Xu Qiao's 4-arm QY16D launched at the end of 2002, which made Xuzhong's 16-ton product win a high share of nearly 76%. Today, manufacturers in the industry are stepping up to achieve breakthroughs in the arm length of medium-tonnage products, such as 20-ton 4-arm, 35-ton five-section cranes.
Although the total sales volume of the crane industry has shrunk significantly compared to 2004, the sales growth trend has entered a normal track.
