A brief introduction HuaHong jaw crusher:

Zhengzhou HuaHong 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, convenient use and maintenance. 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.

Simple pendulum jaw crusher to break the principle:

Moving jaw hanging heart shaft, swinging. Eccentric shaft rotates, link to do reciprocating movement up and down, also do reciprocating motion drives the two pieces of thrust plate, pushing around moving jaw do reciprocating motion, crushing and discharging. This crusher adopts crank connecting rod mechanism, although have very big by the moving jaw broken reaction, while the eccentric shaft and connecting rod bearing is not big, so much on industrial made mainframes and medium-sized machine, used for crushing hard materials. In addition, this kind of crusher work, the trajectories of each point on the moving jaw is spindle as the center of circular arc, arc radius is equal to that point to the axis of the distance, the upper arc small, bottom arc, crushing efficiency is low, its broken than general for 3-6. Because of its simple movement, therefore calls simple swing jaw crusher.

Jane simple pendulum jaw crusher compact structure, small eccentric shaft, a bearing; Because of the moving jaw vertical displacement is small, processing material less excessive broken phenomenon, when moving jaw jaw plate wear small.

Compound pendulum jaw crusher to break the principle:

Upper jaw hanging on the eccentric shaft directly, as the crank connecting rod mechanism by the direct drive of eccentric shaft, the lower end of the moving jaw hinge connecting thrust plate support after the frame of the wall. When the eccentric shaft rotation, the trajectories of each point on the moving jaw is a circular line of suspension point (radius) is equal to the eccentricity, gradually become oval down, more to the bottom, the partial the oval, until the bottom and the thrust plate connection point trajectory for arc line. Due to this kind of mechanical motion trajectory of each point on the moving jaw is more complex, so called complex oscillating jaw crusher.

Compound pendulum jaw crusher compared with simple pendulum, its advantage is: quality is lighter, less component, the structure is more compact, crushing cavity is good, the outside material block by uniform broken, to move the lower jaw introduced mandatory finished discharging, so the productivity is higher, than with the specifications of the simple pendulum jaw crusher; 20-30% higher productivity Material block at the bottom of the moving jaw have larger rolling up and down movement, prone to cube shape discharge, reduce the flake like Jane in the pendulum product composition, product quality is better.

Jaw crusher (jaw broken) simple swing jaw crusher and complex swing jaw crusher two types, are similar in their works, the trajectories of moving jaw have bigger difference. Simple swing jaw crusher, because of the moving jaw is hung on the supporting shaft, so when the moving jaw make reciprocating motion, the trajectories of each point on the moving jaw is circular, and under the horizontal stroke is small, and at the bottom of the moving jaw (row ore mouth) is the largest. Because of falling into ore crushing cavity, the upper are big ore block, often can not meet the necessary amount of compression, ore crushing large deposits of the upper, to crush many times repeatedly, can be broken. Crushing load is mostly concentrated in the lower part of the crushing cavity, the jaw didn't even work, which reduces the crusher production capacity. At the same time the crusher of vertical stroke is small, small grinding exfoliation, row ore is slow. But the jaw plate wear lighter, less crushing products. Complex swing jaw crusher, due to its moving jaw is connecting rod connecting rod, under the drive of eccentric shaft, the trajectory of points in the moving jaw approximate elliptic, ovality is under the small, its upper approximate circle. This crusher horizontal stroke is just the reverse of simple pendulum jaw crusher, the lower part of upper big is small, the upper horizontal stroke is about 1.5 times that of the bottom so that you can meet the required amount of compression crushing cavity upper large ore crushing. At the same time, the moving jaw vertical stroke is larger than the horizontal stroke, especially the row ore mouth, its vertical stroke is about 3 times of horizontal stroke, is conducive to row ore and increase production capacity. Practice shows that under the same conditions, the compound pendulum jaw crusher production capacity is about 30% higher than Jane pendulum jaw crusher. But the jaw plate wear fast, the product had shattered.

Features:

1, crushing cavity depth and no dead zone, the improvement of yield and the ability to feed. 2, its broken than big, product granularity. 3, the gasket type discharging mouth adjusting device, convenient and reliable, the adjusting range is big, to increase the flexibility of the equipment. 4, safe and reliable lubrication system, components, and convenient to replace equipment maintenance is simple. 5, simple structure, reliable operation, low operating costs. Equipment and energy saving: stand-alone energy saving 15% ~ 30%, the system energy saving more than double. 6, the discharging mouth wide adjustment range, can meet the requirements of different users. 7, low noise, little dust.

Runtime environment:

The huge stone broken into small stones in the process, the first line of crusher is usually the "primary" crusher. The longest history, also is the most strong crusher jaw crusher. Jaw crusher for feeding, material from the top entry into the crushing chamber containing jaw teeth and jaw teeth with great force will be material to the room wall, will break into smaller stones. Support jaw teeth movement is an eccentric, the eccentric shaft through the fuselage structure. Eccentric motion is usually produced by fixed on both sides of the flywheel. Often use flywheel and eccentric support bearings are of spherical roller bearings, bearing working environment is very harsh. Bearings must withstand the huge impact load, and high temperature abrasion sewage. Although the work environment is very harsh, jaw crusher still need to work very reliable, it is the key to guarantee the production efficiency.
