Jaw crusher appeared in 1858. Although it is an ancient crushing equipment, but because of a simple structure, reliable Shanghai Raymond powder machine manufacturers, easy to manufacture, easy maintenance, etc., so still in metallurgy, mining, building materials, chemicals and railway sectors widely available. In metal mining, which is used mostly for hard or medium hard ore crushing and broken. Jaw crusher is usually in accordance with the movable jaw plate (moving jaw) motion characteristics to classify the Raymond mill manufacturers, the industry's most widely There are two main types: 1, moving jaw to make a simple swing elbows plate mechanism (called simply tilting) of jaw crusher. 2, the movable jaw for complex single swing bracket means (so-called complex swing) of the jaw crusher. Hydraulic technology has been applied Hebei Raymond mill crushing equipment manufacturers in the emergence of a hydraulic jaw crusher. (1) - simple pendulum jaw crusher; (2) - compound pendulum jaw crusher; (3) - hydraulic jaw crusher. Crusher Despite late, but fast development. It has been our cement, building materials, coal and chemical and mineral processing industries are widely used in a variety of ores, and crushing operations is also used as ore crushing equipment. Crusher is so rapidly mainly because it is important that they have the following characteristics. Uniform particle size. Less than crush phenomenon. This crusher. Is the use of the kinetic energy of broken ore, ore and each has the kinetic energy and quality of the ore block in Sichuan Raymond powder machine manufacturers, proportional. Thus, in the process of crushing, large pieces of ore by a greater degree of fragmentation, but ore smaller particles, under certain conditions, not to be broken. Therefore, a uniform particle size of the crushed product. Henan Raymond mill manufacturers | Lei machinery | Raymond mill manufacturers provided by Zhengzhou Machinery Co., Ltd. Lei.
