In the domestic shredder industry, Kemi is a well-deserved big brother. When the founder Zhong Fenqiang began to engage in shredder assembly in 1993, there was only one state-owned enterprise in the domestic shredder market. In the past 20 years, the company has led the development of China's shredder industry, submitted the white paper on the shredder industry standard, and built the country's largest shredder OEM export base, with an annual export volume of 300,000 shredders, plus the products of the Commurgy brand, 50% of the shredders in Japan come from the Coministry factory. In 2017, Kemi became the brand of paper shredder procurement in CCB's business outlets, and more than 20,000 CCB outlets across the country use Kemi's shredders.
 
Although the initial products often encounter failures such as paper jams and blockages, the price is only a quarter of that of European and American products of 7 or 8,000 yuan, and it is easy to maintain, and it is still well received. After making a profit, the company invested most of its funds in product research and development, and pioneered a safety stop system similar to Van Rooss in China. The stop-and-go technology has greatly reduced the safety hazards and has become an epoch-making invention in the shredder industry, including Yingmingshi, the vast majority of opponents such as Bonsai, Deli, Qixin, and Aurora have not yet mastered it.
 
The product line of the company is also very complete, and like Van Roos, it is mainly divided into large shredders, high-security shredders and office shredders. The high-secrecy series is a high-quality product of the Ministry of Science and Technology, and a number of products have obtained the confidentiality certificate issued by the State Secrets Bureau. G-6500 is the strongest in the industry 1mm×1mm, with a price of tens of thousands of yuan. S-550 takes into account confidentiality and price, the shredding effect reaches 2mm×2mm, after sacrificing endurance and crushing speed, the price is only one-tenth of G-6500, about 1600 yuan. However, both of these models are average in terms of paper feeding, and can only put 5 sheets of paper at a time.
 
Although confidentiality is the core function of paper shredders, efficiency and operation experience have become more important selection criteria under the trend of the shredder market from large government enterprises to small and medium-sized enterprises and families. Among the office shredders of the Ministry of Science and Technology, the efficiency and experience of the King Kong series are the best: the paper feeding volume is more than 15 sheets/time, and the average shredding speed reaches 3.2m/min, which is the top performance in the office model, and the level 4 secrecy is completely sufficient. The high-end platinum diamond and Rui diamond are equipped with a safety contact stop system, which is closer to the configuration of Van Roos 73CI and 79CI, and the continuous working time of more than 40 minutes is longer, and the price is correspondingly higher by 300 yuan, which is 1600-1700 yuan. Although the shredding speed of 2.5m/min of Black King Kong has dragged its feet, it is only 999 yuan, which is still worth choosing.
 
Due to the large contrast between cost input and market feedback, as a domestic brand, the cost performance of Kemi's large-scale shredders is not as good as that of Van Roshi and Yingmingshi from afar. Platinum Shield P series is the representative of the large shredder of the Bureau of Science and Technology, the top configuration of the P-3450 can work continuously for 24 hours, and Van Roes 485CI is on par, but the single feeding volume of 45 sheets is more than 30 sheets of 485CI, the price is nearly 60,000 yuan, more than 20,000 more expensive than 485CI, and it is one of the most expensive shredders on the market.
 
Compared with the perfect warranty commitment of Van Roos and Yingmingshi, many domestic brands, including Bureau of Science and Technology, have a national warranty of up to one year. However, many of our consumables (such as gears) are available online, and the price is between 30 and 50 yuan, so it is more convenient to replace and repair them yourself.
