The working principle, application field and type of universal crusher
The universal pulverizer uses the high-speed relative motion seen by the movable sprocket and the fixed sprocket to make the pulverized material crushed by the combined action of tooth impact, friction and material impact. The structure of the machine is simple, firm, stable, and the pulverization effect is good. The pulverized material can be directly discharged from the grinding chamber of the main machine, and the particle size is obtained by replacing the mesh screen with different apertures, and the machine is all stainless steel. The inner wall of the casing is machined to achieve a smooth surface, which changes the phenomenon of rough and powder accumulation on the inner wall of the previous model, making the production of medicines, food, chemicals and other products more in line with national standards and meeting the requirements of GMP. First, the working principle of the universal crusher Using the relatively high speed operation between the movable sprocket and the fixed sprocket, the pulverized object is impacted by the spur, Friction and material collide with each other to obtain pulverization. The pulverized material can be directly discharged from the grinding chamber, and the particle size is determined by changing the mesh of different meshes. The structure of the machine is simple, sturdy, stable, and the pulverized material is fast and uniform, and the effect is good. The machine is made of stainless steel material. All the tooth grooves inside the casing (crushing tank) are precision machined to achieve smooth surface and easy to clean. It changes the rough inner wall of ordinary crusher, easy to accumulate powder and difficult to clean. Pharmaceutical, chemical and other production can meet the national standards and meet the sanitary requirements of GMP. Second, the application of universal crusher Universal crusher is suitable for pharmaceutical, chemical, metallurgy, food, construction and other industries. The processing of hard and difficult materials, including plastic, copper wire, Chinese herbal medicine, rubber, etc., can also be used as a supporting equipment for the micro-grinder and superfine grinding machine. Its powder collection chamber adopts a fully enclosed sound-absorbing structure, which can effectively reduce the working noise. The machine is equipped with a cooling device to reduce the machine temperature and make the work more stable. The motor speed of the machine is 5000 rpm. This machine is made of Icr18Ni9Ti stainless steel material and has strong wear and corrosion resistance. It is suitable for processing advanced and corrosive materials. The machine adopts the impact crushing method. After the material enters the crushing chamber, it is impacted by six movable hammers rotating at high speed. The ring gear and the material collide with each other to crush, and the crushed material enters through the mesh hole with the help of airflow. Powder bag, leaving no residue. It has the advantages of high efficiency, low noise, reliable performance and product quality, safe operation, low drug hygiene and low loss. Third, the type of universal crusher (1) Roller mill is a kind of machine for sawing and grinding feed by using a pair of cylindrical grinding rolls that rotate relative to each other. It has the advantages of high productivity, low power, convenient adjustment, etc., and is mostly used in the wheat flour industry. In the feed processing industry, it is generally used in the first process of secondary pulverization. (2) Hammer-type feed mill is a machine that uses a hammer that rotates at a high speed to crush the feed. It has the characteristics of simple structure, strong versatility, high productivity and safe use. It is commonly used in 9F-45, 9FQ-50 and 9FQ-50B. (3) Claw-type feed mill is a kind of machine that uses high-speed rotating claws to crush feed. It has the advantages of small volume, light weight, fine product size and high working speed. In China, nervous system drugs are also one of the drugs with the most rapid sales growth in recent years. In 2002, nervous system drugs occupied 5.9% of the entire pharmaceutical market share, and the total sales amount increased by 9.4%. buy nootropics,nootropics benefits,nootropics for adhd,nootropics for weight loss,nootropics supplements Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptidenootropics.com
With the increasing trend of urbanization and aging, the elderly population in China has exceeded 120 million, and the incidence of geriatric diseases, especially mental diseases, is increasing year by year. With the increase of residents' income, the elderly's requirements for quality of life also increase. As a result, the demand for drugs to treat mental illnesses such as Alzheimer's has soared. In WHO drug classification, psychotropic drugs and nootropic drugs are grouped into one class. We briefly analyzed the development trend of this class of drugs through the clinical drug use data collected from more than 300 domestic key hospitals by Chinese Pharmaceutical Association.
The overall market size of this class of drugs is about 1.22 billion yuan, the consumption sum increased by 5.0% in 2002, but the sales quantity increased by 11.2%. The main reason why the consumption sum did not increase with the sales quantity is that several main varieties of this class of drugs, such as piracetam, cobalt bin amide and ginkgo biloba leaf, etc. In 2002, the price of selling units fell sharply due to bidding. Among these drugs, ginkgo biloba preparation occupies the largest market share, accounting for more than 1/3 of the market share, ganglioside ester and cobalt bin amide combined also occupy nearly 1/3 of the market share, piracetam and other "sitan" drugs occupy nearly 10% of the market share, the rest of the drugs occupy less than 5% of the market share. At present, more than 20 ginkgo leaf production enterprises, piracetam production enterprises more than 70, have entered the stage of price competition, profit repeatedly diluted.
In the first-line varieties, except ginkgo biloba leaves preparation maintained vigorous vitality, the growth of other varieties were weak, especially the traditional variety piracetam suffered from bidding
