What is jet mill?
Jet mill grinder is a kind of crushing machine that uses air as the crushing medium. The airflow grinder is mainly composed of a feed port, a crushing chamber, a classifier, and a discharge port. By compressing the air to form a high-speed airflow, the material is subjected to strong mechanical force and airflow friction and shearing in the crushing chamber, which serves the purpose of crushing. During the crushing process, due to the continuous collision and shearing of the material, the material can be completely refined and products with extremely small particle sizes are obtained. The airflow grinder is suitable for the preparation of fine or ultrafine powders that are difficult to be crushed by general machinery and have large wear properties.
First, the working of the jet pulverizer
An airflow grinder is a device that uses high-speed airflow to impact and shear materials to crush them. Its working principle is to spray compressed air at high speed through a high-pressure nozzle to form a strong airflow. The airflow collides, rubs and shears with the material, crushing the material into fine powder.
Second, the characteristics of jet mill
- High crushing efficiency: The crushing efficiency of the jet crusher is high, allowing the material to be crushed more finely.
- Easy to operate: The operation of the airflow crusher is very convenient and easy to control and adjust.
- Low pollution: The airflow crusher has low noise, is environmentally friendly and pollution-free, and can effectively reduce environmental pollution.
- Wide range of applications: Airflow crushers can be applied to a variety of materials, including non-metallic minerals, pharmaceuticals, chemicals, metallurgy, and other industries.
Third, the advantages of airflow grinding
- Save energy: The energy utilization efficiency of the jet crusher is high, and it can save a lot of energy compared with the traditional crusher.
- Easy to maintain: The structure of the air crusher is simple, making it easy to maintain and maintain.
- Suitable for automation: The use of PLC can achieve automated control of the airflow crusher, including initial settings, control switches, operation monitoring, safety protection, and fault detection and alarm. It can be set and adjusted through the programming interface, and real-time data can be obtained by connecting sensors for monitoring and recording.
- Ultra-fine crushing: Jet crushers can crush materials finer, meeting the demand for high-end powder equipment in the pharmaceutical industry.
Fourth, the shortcomings of the jet milling
Easy to generate static electricity: The airflow crusher is prone to generate static electricity during operation, which may cause damage to the equipment or put the operator’s safety at risk.
Treatment method: To reduce the risk of static electricity while using the airflow grinder, several measures need to be taken. First, the equipment needs to be grounded. The grounding wire should be connected to an independent grounding pile to ensure that the grounding resistance is less than or equal to 10 ohms. Secondly, the inlet trend and outlet trend of the equipment should be set up with anti-static tubes. The inner diameter of the tubes should not be less than 8 mm, and there can be no dead ends. In addition, when operating, the staff should wear anti-static overalls and anti-static shoes, and wear anti-static gloves. During processing, pure air should be continuously added to the equipment to ensure that the electrostatic field strength inside the equipment does not exceed the safe threshold. In the daily maintenance of the equipment, it is necessary to regularly dust the equipment and replace the worn parts in a timely manner to ensure the good operation of the equipment.
The cost of equipment is high: the cost of equipment for air crushers is high, which may be unbearable for some small businesses. The cost mainly includes the manufacturing of machinery and equipment, the purchase of materials, and the installation costs, which may lead to excessive financial pressure on enterprises.
Maintenance difficulties: The jet crusher’s internal structure is complex, requiring professional technicians to perform maintenance to ensure the normal operation of the equipment and prolong its service life.
Choosing the right supplier is the best solution to the above shortcomings. Here are some suggestions that may help you choose the right airflow crusher for you:
- Understand the crushing requirements: First, you need to clarify the type and size of materials you need to crush to determine the level of crushing and the power required. For example, if you need to crush fragile materials such as plastic and paper, then the power required by the air crusher is relatively small, but if you need to crush hard materials such as iron and stone, then the power required by the air crusher is relatively large.
- Examine the manufacturer: Understanding the reputation, production quality, and after-sales services of the air crusher manufacturer will help you choose a reliable supplier. In addition, it is recommended that you choose manufacturers with rich experience in related fields to ensure their technical level and after-sales services.
- Test the crushing effect: Before choosing an air crusher, it is recommended that you conduct some simple tests to evaluate its crushing effect. You can choose some samples for crushing, observe their particle size, uniformity, yield, and other indicators, and then choose the most suitable air crusher for your requirements.
- Consider price and economy: the price of an airflow grinder varies by model, manufacturer, function, and other factors. When choosing an air flow grinder, you need to weigh its price and economy. You need to consider the long-term use cost of the equipment, including maintenance costs, consumables costs, etc.
- Ensure safe operation: When choosing a jet crusher, you also need to ensure its safe operation. Some jet crushers may have dangerous factors such as high temperature and high pressure, so it is necessary to strictly abide by safe operating procedures and ensure that the equipment meets relevant safety standards during operation.
