Introduction and selection techniques of hammer mill

Hammer mill is a mill is currently the most widely used, the degree of electrical products is higher, the versatility is good, some of the hammer and the rotor is connected with the metal foreign body, into the grinder, just break the screen, not the occurrence of major accidents, but crushing particle size is not uniform, the powder is more, its structure is composed of feed in the mechanism, the crushing chamber (rotor, hammer, sieve, tooth plate), discharging part (fan, collecting drum, dust bag) is composed of three parts, work, feed from the feed mechanism into the crushing chamber, fly to the tooth plate in the hammer high-speed rotary blow, by again and the tooth plate collision bounce back after the hammer blow, while the screen surface with a hammer sheet, the feed has been strongly influenced by the friction in repeated combat collision and friction effect, feed has been crushed, mill without blower, by indoor airflow pulverization The crushed material discharged through the sieve. With fan mill, the crushing object from out of the sieve that is required by the powder collecting device (such as a barrel, a dust collecting bag) will be mixed in the air air and crushing and separating.

Selection techniques
1.first according to the required thickness selection and hammer line speed to match the mill series; if hammer line speed does not match, reduce the work efficiency of the mill, and even cause mill can not work normally. Wire speed slow will cause broken for a long time, so that the material accumulated in the grinding chamber, causing sticking screen, reduce sifting efficiency and sifting effect, increase the hammer motion resistance, caused by non normal work of mill; the line speed too fast, will cause crushing particle size is not uniform and a waste of power consumption.

2.according to the production scale required yield selection hammer mill: grinder type size determines the output size, according to the configuration of the grinding process, the selected output of a grinder should be greater than 10 percent yield design.
