As early as the primitive era, there had appeared simple crushing equipment. With the development of human civilization, this simple crusher has also experienced the evolution from manual to steam era to mechanical intelligence. That’s to say there is a modern industrial evolution on crusher.
As early as 2,000 B.C, China had the most smashing tool —Chu Jiu, a major cereal husking tool. And it evolved into a pedal (200 B.C to 100 B.C) later. Although these tools can't come up with current electric equipment, they have the prototype of crusher and their way of breaking is still intermittent.
Mletn¨ªk s poh¨¢n¨§n¨ªm zv¨ª?ec¨ª silou was continuously crushing tools as crusher used by the humanity in the earliest period. The other is roll milling (appearing later than animal’s).
Dv¨§ st¨§ let pot¨¦, na z¨¢klad¨§ t¨§chto dvou n¨¢stroj?, vyvinul starov¨§k? ?¨ª¨¾an Du Yu vodn¨ª ml?n s hydraulickou energi¨ª jako poj¨ªzdn¨ª silou, aby zv??il ¨²?innost drcen¨ª na novou ¨²rove¨¾. Krom¨§ pou?it¨ª pro zpracov¨¢n¨ª obil¨ª se tyto n¨¢stroje postupn¨§ roz?¨ª?ily i na drcen¨ª jin?ch materi¨¢l?.

P?ed 19. stolet¨ªm zem¨§ po cel¨¦m sv¨§t¨§ st¨¢le pou?¨ªvaly p?vodn¨ª ru?n¨ª metody k drcen¨ª a t?¨ªd¨§n¨ª materi¨¢lu. S pokrokem spole?nosti a technologie tato p?vodn¨ª ru?n¨ª metoda ji? nedok¨¢zala uspokojit pot?eby rozvoje v?roby.
P?¨ªchodem parn¨ª a elektrick¨¦ ¨¦ry se v?ak v?echno zm¨§nilo.
Lid¨¦ za?ali pozn¨¢vat stroje a za?ali vyv¨ªjet za?¨ªzen¨ª pro drcen¨ª a t?¨ªd¨§n¨ª, kter¨¢ nahradila ru?n¨ª pr¨¢ci.
V roce 1806 se objevil valcov? drti? poh¨¢n¨§n? parn¨ªm strojem.

V roce 1858 vynalezl Ameri?an E.W. Black ?elistov? drti? na drcen¨ª kamen¨ª.

Jaw crusher’s structure is double bracket type (simple swing type). Since it has advantages of simple structure, easy manufacture and maintenance, reliable work, small volume and height, it is still widely used in crushing various materials, such as a variety of ore, solvent, slag, building stone, and marble and so on.
K roku 1878 Ameri?an¨¦ vynalezli rota?n¨ª drti? s nep?etr?it?m drcen¨ªm; jeho produk?n¨ª ¨²?innost je mnohem vy??¨ª ne? u p?eru?ovan¨¦ho drcen¨ª ?elistov?m drti?em.

V roce 1895 Ameri?an William vynalezl impaktn¨ª drti? s ni??¨ª spot?ebou energie.
S neust¨¢l?m rozvojem produktivity ?elistov? drti? nedok¨¢zal pln¨§ uspokojit pot?eby drcen¨ª. Proto lid¨¦ navrhli ¨²?inn¨§j?¨ª impaktn¨ª drti?.
V?voj impaktn¨ªho drti?e lze datovat do 50. let 20. stolet¨ª, kdy se struktura drti?e za?ala m¨§nit.
Do roku 1924 N¨§mci nejprve vyvinuli jedno- a dvourotorov¨¦ n¨¢razov¨¦ drti?e.
V roce 1942, na z¨¢klad¨§ konstruk?n¨ªch rys? a principu ?innosti drti?e s klecov?m klec¨ª, Anderson vynalezl ?adu drti?? AP, kter¨¢ se podob¨¢ modern¨ªm n¨¢razov?m drti??m.
Stroj zvl¨¢d¨¢ relativn¨§ velk¨¦ materi¨¢ly s vysokou produktivitou. Jeho jednoduch¨¢ konstrukce je vhodn¨§j?¨ª pro ¨²dr?bu, tak?e se tento typ n¨¢razov¨¦ho drti?e rychle vyv¨ªjel.
Do roku 1948 americk¨¢ spole?nost vyvinula hydraulick? ku?elov? drti?, kter? se od t¨¦ doby pou?¨ªv¨¢ v pr?myslov?ch odv¨§tv¨ªch.
Prvn¨ª ku?elov? drti? na sv¨§t¨§ p?vodn¨§ vyrobili brat?i Symonsovi (Symons?v ku?elov? drti?). H?¨ªdel je zasazena do excentrick?ch z¨¢v¨§s? a poh¨¢n¨§na jimi k pohybu kyvadla pohybliv¨¦ho ku?ele. Pohybem pohybliv¨¦ho ku?elov¨¦ho oblo?en¨ª tam a zp¨§t je hornina drcena a oh?b¨¢na nep?etr?it¨§ v drt¨ªc¨ª komo?e.

S rostouc¨ª dokonalost¨ª teorie drcen¨ª a dal?¨ªm rozvojem v¨§dy a techniky se objevuj¨ª r?zn¨¦ druhy vysoce v?konn?ch drti??. Tyto drti?e zna?n¨§ zlep?ily ¨²?innost drcen¨ª.
R?zn¨¦ pr?myslov¨¦ odv¨§tv¨ª maj¨ª r?zn¨¦ po?adavky na produkty, proto se objevila ?irok¨¢ ?k¨¢la drtic¨ªch stroj? na z¨¢klad¨§ r?zn?ch princip? ?innosti, jako jsou vibra?n¨ª ml?ny, p¨ªse?n¨¦ ml?ny a koloidn¨ª ml?ny.
Ji? v 70. letech 20. stolet¨ª byly vyvinuty velk¨¦ rota?n¨ª drti?e s produkc¨ª 5?000 tun za hodinu a pr?m¨§rem materi¨¢lu 2?000 milimetr?.
Sou?asn¨§, s c¨ªlem zv??it mobilitu drti?e, byl vyvinut mobiln¨ª drtic¨ª a t?¨ªdic¨ª z¨¢vod, kter? se mohl flexibiln¨§ pohybovat v oblastech rychl¨¦ho p?em¨ªst¨§n¨ª a stal se extr¨¦mn¨§ popul¨¢rn¨ª.
China didn't start having crusher until the 1950s. Domestic impact crushers were limited to medium and hard materials such as coal and limestone before1980s. Until the end of 1980s, China introduced KHD type hard rock impact crusher, which filled the domestic blank of crusher. But it’s still behind many in developed countries for more than 20 years.
