Who Does Invent Rock Jaw Crusher in the World?

Jaw crusher in mining, building materials, construction and other departments are mainly used as coarse crusher and crusher.According to the inlet width size is divided into large, medium and small three, inlet width is greater than 600 mm for large machines, feed port in 300-600 - mm width for medium-sized machine, feeding mouth width is less than 300 mm for the minicomputer.Jaw crusher structure is simple, easy manufacturing, reliable work.
Jaw crushers can be classified into two types, namely single toggle jaw crusher and double toggle jaw crusher according to different working principles. The outer frame of jaw crusher is generally made of cast iron or steel. The jaws themselves are usually constructed from cast steel. They are fitted with replaceable liners which are made of manganese steel, or Ni-hard (a Ni-Cr alloyed cast iron). Work part of the jaw crusher is two pieces of jaw plate, one is the fixed jaw plate (jaw), vertical (or the upper slightly extraversion) fixed in front of the body wall, the other is movable jaw board (dynamic jaw), tilt, and fixed jaw plate form on the small crushing cavity cavity (work). Activity fixed jaw jaw slabs with periodic reciprocating motion, sometimes separately, sometimes near.Separately, material into the crushing cavity, finished products from the lower discharge;Approached, the materials are squeezed between two pieces of jaw plate, bending and fracturing effect and broken.The motion of the jaw jaw crusher according to the activities in different ways, can be divided into simple oscillating jaw crusher (Jane pendulum jaw crusher). Complex oscillating jaw crusher (compound pendulum jaw crusher) and integrated oscillating jaw crusher.
Modern machinery such as crushing machinery is in the steam engine and electric motor gradually perfected and created one after another after the promotion.In 1806 the roller crusher, driven by the steam engineIn 1858, the United States invented the black broken rock jaw crusher;In 1878 the United States developed with continuous crushing action of gyratory crusher, its production efficiency is higher than the intermittent movement of the jaw crusher;In 1895, the United States, William invention energy consumption low rock impact crusher.
