The Multifunctional Hammer Mill is widely used in crushing various biomass wood waste and straw material. The motor and the hammers are directly connected by the coupling. There is no dead angle during the crushing so the finished product is very fine. The corners of the hammers are welded with high hardness material like carbon tungsten alloy. The welding layer thickness is around 3mm. The lifetime is 7- 8 times by normal 65Mn overall quenching hammer. The rotor has made the balance test and can work backward. It`s the best choice to prepare milled material for pellet machine.

At the same time, the import volume of liquefied crude oil and raw materials at Ningbo Port is very large. According to Ningbo Customs statistics, in the first half of this year alone, crude oil imports from Ningbo Port exceeded 20 million tons, a record high, reaching 204.44 million tons, worth US$6.88 billion, an increase of 9.6% and 51.7% respectively year-on-year. . As of August, Ningbo Port imported 3.056 million tons of liquefied chemicals, valued at US$2.75 billion, an increase of 16.8% and 38.0% respectively year-on-year. The main types of imports of liquefied products were terephthalic acid, ethylene glycol and styrene, with import volumes of 1.052 million tons, 774,000 tons and 273,000 tons respectively, mainly from South Korea, the Middle East, and China Taiwan.
The phenomenon of “large and small inflows†of petrochemical products at Ningbo Port reflects, to a certain extent, the imbalance in the petrochemical industrial chain in the region and even in Zhejiang Province. People often use "big two, small middle" to describe the petrochemical industry in Zhejiang. Large upstream, with the country's largest oil refining company - Zhenhai Refining & Chemicals; large downstream, the end of the industrial chain of fine chemicals, plastics, textile and other industries in the country among the best; middle small, in the middle reaches of the industrial chain is very weak basic chemical industry. Zhejiang is one of the few provinces in China that do not have large ethylene facilities. The vast majority of polymer materials and fine chemical raw materials are dependent on imports or purchased from other provinces, often subject to restrictions on raw material supply. The unbalanced industrial chain has become a major bottleneck restricting local economic development.
However, the favorable development momentum of Ningbo Lingang Petrochemical Industry is affecting and changing the layout of Zhejiang's petrochemical industry. Since Ningbo has the superior conditions for the development of the petrochemical energy industry, foreign investors have come to invest in Ningbo in recent years. British BP, American Dow Chemical, Korean LG Chemicals, Formosa Plastics, Japan's Mitsubishi Chemical Group and other companies have invested in Ningbo Petroleum and Chemical Industry, and created a large number of such companies as Lucky Gold, Pacific Chemicals, Zhejiang Good Chemicals, and Formosa Plastics Petrochemical Industrial Park. Big project. After these projects are put into production, the upstream and midstream industries of Ningbo Petrochemical will form a preliminary system, which will make up for the lack of a link in Zhejiang's petrochemical industry chain and will positively promote downstream industries.
According to a survey conducted by the reporter, Ningbo Lingang Petrochemical Industry is entering the fast track of sound development, and the investment in fixed assets continues to grow steadily: Zhenhai Refining & Chemical completed the technological transformation in the first half of this year, and its crude oil processing capacity reached 18.5 million tons per year; Formosa Petrochemical’s ABS Phase I, PVC and Jufeng Chemical's sulfuric acid production, LG Latex's 35,000 t/y styrene-butadiene latex and other projects were completed and put into production; Zhenyang Chemical's 100,000 t/a chlor-alkali, Otsuka Mitsubishi's PTA, Daan Chemicals such as cellulose diacetate and other major projects were successively started construction; Yantai Wanhua Daxuan's 160,000-ton/year MDI, Donggang Electrochemical's 100,000-ton/year chlor-alkali, and Siming Chemical's synthetic ammonia are about to be completed; Zhenhai Refining & Chemicals Co., Ltd. 100 Tens of thousands of tons/year of ethylene, Zhongjin Petrochemical's 700,000 tons/year PX project will start again. These enterprises chose to settle in Ningbo. What they see is not only Ningbo's outstanding port advantages and locational advantages, but they also value the huge market in the Yangtze River Delta.

“Ningbo Port chemical products are big and small.†Sun Guoxian, director of the Ningbo Pharmaceutical and Petrochemical Industry Office, said, “In the first half of this year, there were 243 petrochemical enterprises above designated size in the city, an increase of 64 from the same period last year, and sales revenue was 386. 8.3 billion yuan, an increase of 42.26% over the same period of the previous year; the export delivery value was only 1.143 billion yuan, an increase of 41.46% year-on-year. Exports accounted for only a very small proportion of total sales revenue.
