Which airflow mill is suitable for boraborium processing?
Inert gas protective gas flow emergency stop. The equipment emergency shutdown trigger switch is connected to the oxygen content tester, and the oxygen content concentration monitors by the oxygen content tester has not reached the preset value in a predetermined time, triggered emergency shutdown, the equipment stopped, the introduction of the wind, the grading machine Delayed, the nitrogen supplement system continues to work until the manual shutdown.Boron is a black or silver gray solid. The crystal boron is black, the hardness is second only to diamond, and the texture is brittle. To processes boraf powder to microscopic ultrafine powder, it is necessary to use the airflow pulverizer, so in the face of various types of airflow mills on the market, which model is more suitable for boar's powder? Let's take a look.
Generally used for boron powder pulverized equipment is a MQW type gas flow pulverizer, which is a mainstream type-fluidized bed airflow mill in a gas flow pulverizer. By using a high-speed airflow to smash the dry material, since the full utilization of the jet is high, the pulverization is not warmed, no pollution, small wear, high precision ... is widely used in low temperature, high purity and high hard and material The fine pulverization, the flammable, explosive, and oxidized materials can be used to achieve closed circuit pulverity, and the inertial is recycled with an inert gas.
MQW type gas flow pulverizer consists of several parts of airflow pulverizer, cyclone collector, dust collector, air blower, and electric control cabinet, etc.. The principle is that after compressed air is dried, it is repeatedly collided with the Raval nozzle high speed, and the material is repeatedly collided with the intersection of the multi-shaped high-pressure airflow, and crushed, and the crushing material will enter the rising air flow. The fractional chamber is separated by the center of the gas flow generated by the centrifugal force generated by the high-speed grading impeller, and the fine particles required for the particle diameter of the particle diameter are collected into the cyclone collector and the dust collector, and the crude particles are collected by the grading impeller blade gap. The fractional impeller taps and drops to the crushing area to continue smashing.
MQW type gas flow pulverizer is superior, one is flexible in combination, which can be smashed, and can be graded separately, one-to-use; second, it can multi-stage series: can be configured 1-5 graded machine Product particle size requires a narrow product; it has a wide range of pulverized particles, and the finished product particle size is adjustable between D97 = 3-150 microns, and the granular shape is good; in addition, this complete system is closed, low dust, low noise The production process is clean and environmentally friendly; and its control system adoptsProgram control, easy to operate. Therefore, it is widely used in chemical, minerals, metallurgy, abrasives, ceramics, refractory materials, pharmaceuticals, pesticides, food, health products, new materials and other industries. ALPA powder technology has always adhered to the development concept of "we use the heart, only the airflow mill", adhering to the "quality first, service-oriented" concept, has been a breakthrough in technological innovation , Technology is developing as cornerstone, constantly improving efficiency and safety of gas flow crushers, is committed to providing customers with safer, energy-saving, environmentally friendly airflow mill products, creating more value for customers, and creates greater interests for employees , Do more responsibility for society.
