Needle disc mill and nail disc mill are a fine impact crusher with one or two rotating discs driven by high-speed explosion-proof motors, which are covered with nail shaped pins. The relative speed of the outer edge pins on the rotating disc can reach 250 m/s. The nail plate mill achieves the goal of ultrafine crushing by striking the material without damaging the crystal form of the material. The rotating disc grinding component of the nail disc mill has various forms to choose from, and the fineness can be adjusted by changing the needle disc speed, so it can flexibly handle the requirements of various raw materials and product fineness. In the production of cell culture media, needle disc mills are often used as grinding components to produce ultra-fine and uniform powder products. The particle size control range of the powder is 10um-200um, and the particle size range is adjustable.
Product Overview：Air Classifier Mill is a kind of ultrafine mechanical pulverizer, which is a fine impact pulverizer that integrates grading and crushing. By adjusting the classification wheel, crushing rotor shape, rotor speed, etc., the crushing size of the product can be flexibly controlled. Generally, products with an average particle size of 10-100μm can be produced. According to the requirements of material characteristics, different PLC automation programs can be set, and customized selection and manufacturing can be made. The ultra-fine mechanical pulverizer is widely used for fine pulverization and ultra-fine pulverization of materials such as chemicals, medicine, food, minerals, and building materials.
Product Overview：The pin mill is a high-speed impact mill. It can be equipped with a variety of different types of hammers and various types of linings/screens. By adjusting the specifications of the hammers, linings and screens, various types of raw materials can be processed. The grinding fineness is usually about 10μm and 1000μm. (Specifically determined by the characteristics of the material), under the ventilation of the rotor, the product will be cooled during the conveying process, so the final product has low fineness and good fluidity. The nail-disc mill is equipped with different grinding elements, which is very versatile and can keep the crystal form of the material from being damaged. It can be used for the pulverization of dry cell culture media.
The hammer mill belongs to the mechanical mill and is a traditional crushing equipment. It is widely used in many industries, such as pharmaceutical, feed, food, paint, chemical and other industries. It has a wide range of versatility, can adjust the grinding fineness, has the advantages of high production output, long life, low energy consumption, easy cleaning, convenient maintenance and so on.
In response to the growing demand for dry powder cell culture medium production, Purdue has launched a self-developed cell culture medium process system, which combines needle crusher and cone mixer to meet customers' various dry powder material crushing needs.
In recent years, with the improvement of professional requirements and the increasing application of highly active drugs, the demand and requirements of isolation technology in the pharmaceutical industry are getting higher and higher, and the requirements for sterile environment in the pharmaceutical process are also increasing. Pudu Tech offers a wide range of isolator products and can accept customization. When you need to protect people and the environment, you can use the negative pressure type of high-live isolator; when you need to protect the product, you can use the positive pressure type of sterile isolator.
Principle: The material enters the crushing silo and is impacted by a high-speed rotating grinding knife to lower the powder. The feeding port is equipped with a star shaped discharge valve to control the discharge speed and prevent the generation of dust during the crushing process.
Product Overview：Pudu Machinery’s jet mill is a spiral supersonic jet mill. After years of research and development and process verification, it has been iterated to the fourth-generation jet mill. The particle size can be controlled such that D90 is less than 2μm, and D100 is less than 10μm or even higher. The experimental type of jet mill is widely used in research and development centers and laboratories in the pharmaceutical, chemical, food, cosmetic and other industries, and can handle 3 -5 kg/h of material milling.
