Knusningsmaskiner: Fortid og nutid

In China, there had been the most basic smashing instrument – ball and attachment in 2000 BC. From the 200 BC to 100 BC,the smashing apparatus – ball and attachment further advanced into the foot pestle. These instruments utilizing the influence were the underlying model of the devastating machine, however their activity was as yet discontinuous pulverizing.

The soonest pounding machine with persistent squashing activity was created by the Lu Ban living in the pre-summer and Autumn Period. The other with consistent pounding activity was the roller granulating apparatus, it showed up later. 200 AD later, Du Yu and other Chinese had built up the water-plant dependent on the foot pestle, and the water was the main impetus, which improved creation proficiency to another level. These machines were utilized for grain preparing, yet in addition stretched out to different materials on the devastating tasks.

Present day smasher had been made after the slow improvement of steam motor and electric engines. In 1806 there showed up steam motor driven roller smasher. In 1858, Blake, in the United States, designed the jaw smasher. Rotating smasher was created in 1878, the creation productivity was higher than the jaw smasher with discontinuous pulverizing activity. In 1895, American William imagined sway smasher which was lower energy utilization.

Then, the crushing apparatus likewise had a relating advancement. In the mid nineteenth century, ball factory had been generally utilized. Pole factory with uniform size of the release was concocted dependent on the improvement of ball plant in 1870. During the 1930s, Americans and Germans had built up a roller bowl factory, roller plant and other vertical shaft plant.

Crushing and Grinding Mine – The Most Common Breakers

Smasher er det samlede ophobningsstof af partikler, der er større end 3 mm af den samlede udtømningshastighed, halvdelen eller en større mængde af den ødelæggende maskine. Opgaver, der regelmæssigt brydes ved at tage sig af og bosætte sig i den grove kornstørrelse på den rodede, den ødelagte og ubetydelige. Sti under den ødelæggende kraft fra smadderen kan generelt isoleres i to klassifikationer: (1) smasher; (2) granuleringsmaskine. Breakers generelt beskæftiger sig med større dele af materiale, grov granularitet, normalt mere bemærkelsesværdig end 8 mm. Dets konstruktion er beskrevet af et specifikt hul mellem de rodede stykker og ikke berører hinanden. Smasher kan opdeles i grov smasher, smasher og fin smasher. Som regel er granuleringsmaskiner, materiale, der beskæftiger sig med mere beskedne, varestørrelsen fin, op til 0,074 mm eller betydeligt mere specificeret. Konstruktionen af ​​en ødelagt del (eller et medie) er i kontakt, det anvendte medium er stålkugler, stålstænger, som sten eller mineralsk firkant. Uanset hvad det er, er et par maskiner ligeledes både sammenstødende og knusende stød, for eksempel fra planten. 5 5. 5 × 1. 8 ç ± ³ plante, der forbereder mineral fra den maksimale længde op til 350-400 mm i størrelse, varefinheden kan nå ca. 40% – 200 årsag.

Rute under den ødelæggende hardware af underliggende attributter (aktivitetshypotese) til division, stort set opdelt i seks klassifikationer.

(1) kæbe smasher (tiger mund). Brudarbejde er ved periodisk at flytte kæben til den faste kæbe presningsfaktor vil hindre arrangøren, hvor det knuste mineral.

(2) kegle smasher. Del inden for og uden for de to kegler i midten af ​​den faste udvendige kegle, indadgående kegle til ukonventionel svingning, konvolutten, hvor mineralet er firkantet, klemt eller brudt.

(3) flyt smasher. Metalkvadrater i de to inverse drejelige ruller fanget i cirklen, grundlæggende ved progressiv dunkende indvirkning, men udover den del af granuleringsstripping er den ødelagte tandrulleoverflade del af job.
