Working principle of Rotary dryer
When rotary Dryer is operating, it shall be in direct contact with heated gas. The dryer consists of a large rotating cylindrical tube. In order to convey the material through the underside of dryer, the dryer should be slanted slightly to ensure that the discharge end is lower than the end of material feed .
Working Principle of Rotary Dryer: Material shall be dried to enter the dryer. When the dryer is rotating, a series of internal fins will lift the material by lining the inner wall of the dryer. When the material reaches certain height to roll the fins back, it will be fell back to the bottom of the dryer, then passing through the hot gas stream as it falls. This gas stream can either move toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be composed of a mixture of air and combustion gases from a burner, and in which case the dryer is known as a direct heated dryer. Alternatively, the gas stream may be made up of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases are not permitted to enter the dryer, the dryer shall be called an indirect-heated type. Indirect heated dryers are commonly used when product contamination becomes a concern. Read How Does HONGKE Rotary Dryer Work?

The policy subsidy is so great that only a handful of actual sales are available. In the private consumption sector, up to now, only 10 pure electric vehicles have been sold in the Shanghai market, and only 25 in Hangzhou. Should we insist on the development of pure electric vehicles, or should we change the main focus to develop hybrid power? Become a new topic for new energy vehicles.
In June 2010, the Ministry of Finance confirmed that five cities, including Shanghai, started private subsidies for the purchase of new energy vehicles. On April 7 this year, the first privately-purchased electric cars in Shanghai were formally put on the road, and eight ordinary citizens became the first people to “eat crabs,†but afterwards they were almost stagnant.
As of now, Shanghai's private-sector purchase of only 10 electric cars is on the list. Why is energy-saving and environmentally-friendly electric cars "comeable?"
In the same model, the price of an electric vehicle is more than twice as expensive as that of a fuel vehicle. Some consumers who are interested in purchasing an electric vehicle generally report that the high one-time cost of an electric vehicle is an important factor that hinders its popularization. Although there are national and local subsidies for cars, up to 100,000 yuan, the Shanghai license, purchase tax, and insurance premiums are too expensive.
Taking a 220 thousand yuan electric vehicle as an example, the purchase tax and insurance premiums are still calculated at the original price before the subsidy, and the purchase tax is nearly 20,000 yuan. The one-year insurance cost is about 5,000 yuan, plus Shanghai's nearly 50,000 yuan in license fees, and the purchase of pure electric vehicles is about 75,000 yuan. If these costs are added, the purchase cost of electric vehicles will be significantly increased, which will greatly reduce the attractiveness of ordinary citizens to purchase and use pure electric vehicles.
Zhu Xiao, the owner of the Chery M1 electric vehicle, gave the reporter an account: her car had a total price of 150,000 yuan, and in addition to the national subsidy of 60,000 yuan, she also had to pay a purchase tax of more than 10,000 yuan. After all, it is much more expensive than an equivalent fuel car. "I saw in the 4S shop that the same Chery M1 fuel car was sold for 38,800 yuan, and my electric car was more than twice as expensive. Besides the purchase tax, the state has set a passenger car with a displacement of 1.6 liters and below to start this year. At a tax rate of 10%, my electric car is zero-emission. How can it be levied on the same standard? This seems unreasonable, she said.
A certain car can only be returned to the factory by the staff to recharge those "early adopters" who have many problems in their use. Zhang Xia, who works in Shanghai Jiading International Automobile City, bought a Zhongke Lifan pure electric vehicle in early April. She found that her electric car could not be recharged at home and could only be returned to the factory for recharging by the staff of Zhongli Lifan. , and then send it back.
Originally, Zhang Xi purchased Zhongke Lifan pure electric vehicle using a DC charging mode, but in the vicinity of the car city, the charging pile built by the State Grid is an alternating current charging mode. "This car needs to be charged with 20 amps of direct current. The existing 12 amps of AC at home cannot be recharged." Zhang Xia reluctantly said.
Compared with the bleakness of the number of privately purchased electric vehicles, the relevant person in charge of the Shanghai International Automobile City, which is the "trial field" for personal consumption of electric vehicles, is still full of confidence.
He said that unlike ordinary cars, electric vehicles are still relatively "tested," and there are no fixed numbers for safety, ease of charging, authenticity of actual mileage, and durability of batteries. Rather than letting “one move to the top†cause chaos, it is better to explore steadily forward now, which is responsible for the development of electric vehicles.
In addition to vehicle subsidies, business models must innovate experts believe that the state's incentive to use electric vehicles has yet to break through innovations. In addition to government subsidies for car prices, business models must be innovative.
On April 22, the “China (Shanghai) Electric Vehicle International Model City†was unveiled. Jiading District was designated as an international demonstration area for electric vehicles. On May 16th, the first operation center of the EV International Demonstration Area, the test-drive test center, was opened to the public and it is expected to receive 20,000 visitors during the year. All this was carried out in an orderly manner in the planning of the Shanghai International Automobile City. Among them, the electric vehicle test drive test center is a business model of innovation. Shanghai International Automobile City has already contacted eight new energy vehicles such as Roewe, BYD, Chery, Zhongke Lifan and Zhongtai for free trial rides. The goal of the center is to become the display platform for major brands of new energy vehicles in the future, and strive to achieve more than 10 new energy vehicle test rides during the year.
The development of new energy vehicles cannot rely on any one of the government, enterprises and consumers. New energy vehicles are faced with supporting issues of urban planning and urban construction, supporting issues for enterprises such as complete vehicles, parts and components, batteries, and power grids. Therefore, governments, enterprises, and consumers need to work together to make overall plans.
“The electric car is just like a kid just learning. The demonstration in Jiading District is the experimental application of the socialization of electric vehicles. The process of this experiment must be controversial, mistake and even failure. We will hold an active, rational and Tolerant mentality, said Fei Xiaomei, deputy director of Shanghai Jiading District.
Shanghai Private Buys Only 10 Electric Vehicles, New Energy Vehicles>
One year after starting the pilot subsidy for private car purchases, Shanghai has sold only 10 pure electric car editors: In February 2009, the Ministry of Finance announced the Interim Measures for the Administration of Energy-Saving and New Energy Vehicles to Promote the Demonstration and Promotion of Financial Assistance Funds. In June 2010, it was confirmed that pilot projects for private subsidies for new energy vehicles will be launched in five cities in Shanghai, Changchun, Shenzhen, Hangzhou, and Hefei. The maximum payable for pure electric vehicles is 60,000 yuan per vehicle; the engine with an engine displacement of 1.6L and below is eligible for energy-saving vehicles. Each vehicle nationwide has a subsidy of 3,000 yuan. Up to now, the list of recommended models for energy-saving and new energy vehicle demonstration, promotion, and application projects has been released to the seventh batch, and pilot cities have also increased from 5 to 25.
