Recently, the Ministry of Science and Technology issued a 2004 part of the project plan for scientific and technological industrialization (National Science and Technology No. [2004] No. 140), and identified a total of 107 key state-level Torch Program projects in 2004. The GJF drying super research and development developed by Zhejiang Fengli Crushing Equipment Co., Ltd. Micro crusher ranked 14th. This is the product in the evaluation of national key new products, included in key scientific research projects in Zhejiang Province, passed the provincial new product appraisal, won the second prize of Zhejiang Provincial Science and Technology Progress Award, and was identified as a series of titles such as high-tech products in Zhejiang Province. A special honor.
The Torch Plan is a high-tech industry development plan approved by the State Council and organized by the Ministry of Science and Technology. Selected key projects from the National Torch Plan Project. The key projects have China's independent intellectual property rights, and the technological level is in the leading position in the domestic same industry. The project products have good market prospects and large industrial scale. They have strong market competitiveness and large market coverage, and are the key high-tech industries for national development. .
Ultrafine crushing technology is a new crushing engineering technology developed with modern high-tech and new materials industries. It has been widely used in chemical industry, metallurgy, mining, building materials, daily chemical, food, medicine, agriculture, environmental protection and Aerospace and many other fields. At present, with the ever-growing social productivity, the ultrafine powder field has increasingly higher demands on the particle size and powder quality of the fine powder. However, domestic industries such as chemicals, pharmaceuticals, foodstuffs, and dyestuffs require dry ultrafine grinding processes. Due to the lag in their technological equipment, they are liable to cause defects such as over-drying, over-comminution, and insufficient fineness, which seriously affect the yield of finished powder products. Quality restricts the development of these industries and related industries.
Experts believe that GJF dry ultrafine pulverizer integrates the three processes of drying, ultrafine grinding and grading. It successfully solves the problem of ultrafine crushing of materials with high water content and is a major breakthrough in powder engineering. Its technology is at the leading domestic level. The triangular ring gear stator and the rotor structure with a high-speed active hammer and the double-screw feeding device with a variable speed dispersion mechanism are the first in China.
Since the machine was included in the implementation of the national Torch Program in 2002, Zhejiang Fengli Company has further innovated the machine, using the advanced international ultrafine powder technology (Germany HOBER technology) introduced to optimize the product structure and achieve high precision. The turbo-ultra-fine classifier and the high-speed impact ultrafine pulverizer are organically combined to achieve the maximum energy-saving effect during the crushing process. The main innovations are: (1) The lower part consists of a ring gear with a triangular gear ring stator and a high-speed active impact hammer, where the material is crushed to a product as low as 3 μm or less due to strong impact; (2) Upper part For the multi-blade, high-precision grading wheel with backward rake of the blade, the finished material with different particle sizes can be sorted out by adjusting the rotation speed of the grading impeller; (3) Double-spiral mechanism with variable-speed dispersing device is adopted to make the adhesion very wet After the materials are fully dispersed, they are evenly added to the crusher; (4) The drying and crushing time is short, which improves the product quality.
The use of users confirmed that the machine has a good drying effect, fine grinding fineness, low energy consumption, long service life, etc., especially suitable for dry ultrafine grinding industry, chemical, food, dyes and other industries, can maximize product quality And productivity, with significant economic and social benefits.
At present, the performance of GJF dry ultrafine crusher has reached the level of similar foreign products, and the price is only 1/3 to 1/5 of the import price. The products are exported to Malaysia, Indonesia and other Southeast Asian countries; the alternative imported products are widely used in many domestic enterprises. , welcomed by users.
