The shredders development has gone through a lengthy process. Can be traced back two thousand duonian formerly known as the "Big Four" of Chinese civilization. Of course, at that time, the equipment is simple, just a simple hand operated machine to break the "leverage". Book day, when it comes to open these. But by the world. Era, steam, early with a strong performance of the automatic grinder. Reach power revolution ", so that the grinder will never change.
The development of the grinding equipment manufacturing industry in China only after the liberation, the first copy. Of course, is modeled on the Soviet Union. 1958, Sino-Soviet split, and at night to withdraw all the experts to help China Construction, took all the design drawings. That year, our technical department in the design stage. Truly effective in the 1966 series design. Since the 1970s, the end to break the equipment began in foreign countries, the gradual emergence of this new technology, such as pneumatic clutch, hydrostatic bearing grinder, advanced lubrication method, the lifting device, and chromium wear Li Ning board and rubber mill steel Li Ning panels, automatic control equipment, etc., but also increase the variety and expand the size of grinder, a new level of China's manufacturing industry, and increase to narrow the gap with foreign advanced level.
Universal grinder mixed dusting the principle of the design and development is made applicable to the pharmaceutical, food, chemical and other industries, and used widely. Universal grinder simple structure, the grinding chamber disassembly and easy to clean, crushed indoor where contact with the material part, are made of stainless steel, acid corrosion, so that the crushed material to better meet the health requirements. The machine easy to move, smooth operation, low noise, good grinding efficiency, and low power consumption.
Universal high speed grinder purely mechanical side port blade and the other side of the blade of the Four Gig crushed material being crushed by high-speed rotating blade shearing. The aircraft can also use a variety of different size blades of different materials, particle size replacement screen.
Universal grinder three parts by the main engine, electronically controlled, compact design, reasonable structure. Applies to the pharmaceuticals, chemicals, pesticides, food and food industries, and used widely. Grinder equipped with a hierarchical institution, to make crushing, grading once. Vacuum conveying an endless stream of discharged heat the cavity of the grinder machine crushing operations, it is also adapted to the heat sensitive materials crushed. 30B series universal grinder to adapt to a wide range of continuous production process, the particle size is adjustable; can handle a variety of materials such as: chemicals, food, cosmetics, dyes, resins, shell material, crushing and classification.
1) universal grinder is not only applicable to dry and brittle material, also applies to part of the toughness and fiber materials.
2) strong friction, the material in the large-caliber machine temperature rise, leading to dehydration.
3) broken to immediately release, resulting in excessive crushing waste of energy.
4) crushing uniform particle size. |
