Working principle and precautions of powder vacuum feeder

Vacuum feeding machine - the commonly used vacuum feeding machine is divided into electric vacuum feeding machine and pneumatic vacuum feeding machine, which can replace the manual feeding to the hopper, reaction tank, dryer, mixer and other equipment, and also has the function of automatic dust collection and dust removal The conveying capacity of the conveyor is generally 100-5000kg / h Working principle of vacuum feeding machine: the vacuum feeding machine mostly adopts the way of vacuum suction The working principle of vacuum conveying is to form a certain negative pressure in the hopper cavity and make the material inhale into the hopper The working process of the full-automatic vacuum conveyor is: negative pressure is generated by the vacuum generator or roots pump, when the closed system reaches a certain degree of vacuum, it starts to suck the material, and then discharge the material into the hopper after the completion of suction, and after a certain preparation time, the next cycle process is carried out In this reciprocating cycle, the material can meet the demand of the equipment Use and precautions of vacuum feeding machine: material particle size and shape, material conveying distance and material conveying, material feeding position, material density and material fluidity, material temperature, material degree and material compatibility Bending quantity, energy consumption, material toxicity, inflammable and explosive.
