The jaw crusher is a kind of crushing equipment that is widely used and can be divided into compound pendulum jaw crusher (i.e. single-toggle plate jaw crusher) and simple pendulum jaw crusher (i.e. double-toggle plate jaw crusher).
Generally, the compound pendulum jaw crusher is applicable for various ores and rocks with coarse/medium crushing and compression strength below 250Mpa. The crushers of three specifications above PEF0609 may also be used to crush various hard ores and rocks. PEF-X compound pendulum jaw crusher for fine crushing is only applicable for ores and rocks with hardness below medium normally, while the simple pendulum jaw crusher can be used to crush ores and rocks with various hardness and especially applicable to crushing of various hard and highly abrasive materials. The jaw crusher is a kind of crushing appliance that is widely used and is characterized by simple structure, reliable working, easy operation, convenient maintenance and low cost for equipment and production. In addition, it can be divided into compound pendulum jaw crusher (i.e. jaw crusher with crank and rocker mechanism for complex pendulum of movable jaw) and simple pendulum jaw crusher (i.e. jaw crusher with crank and double-rocker mechanism for simple pendulum of movable jaw) based on its structural features, which is widely used in such industries as metallurgy, mining, building materials, chemical industry and cement for coarse and medium crushing operations. The compound pendulum jaw crusher is suitable for crushing of ores and rocks with compression strength below 250Mpa, while the simple pendulum jaw crusher can be used to crush ores and rocks with various hardness and especially applicable for crushing of various hard ores and rocks.
The compound pendulum jaw crusher is mainly composed of frame body, movable jaw parts, toggle plates, locking devices with pull-rod spring and driving devices. The movable jaw is driven by motors for complex pendulum through triangle belt. Ores added into the crushing cavity crush subject to extrusion, splitting and bending due to pendulum of movable jaw. The ores crushed by crushing cavity are discharged out of the crusher at the moment of leaving fixed toothed plate.
Shunda Heavy Mining Machinery Co. Ltd., was started in 1988, with the head office in Shenyang. Shunda is the second to none large mining machinery manufacturing private enterprise, which has three branches: Shenyang Shunda Heavy Mining Machinery Co., Ltd, Shenyang Qiangqiang Heavy Industry Co., Ltd. Shenyang Evigor Motors Co., Ltd. and several sub-branches.
In 2001, Shunda enters the manufacturing industry of heavy mining machinery, and registered the brand “Shunda Mining Machinery”. Now, we have a total staff of 1000 people, two production bases with a total area of 240,000㎡(more than 80,000 ㎡ are building area for office and workshop. The annual output is more than 1 billion RMB.
Our products are widely used in big scaled mining areas both at home and abroad. We also have local offices in Xinjiang, Hebei, Shanxi, Inner Mongolia, Fujian, Guangdong and other places. In future, we are planning to establish offices South Africa, South America, Southeast Asia.
The main products of Shunda are hydraulic gyratory crusher(max 1.6m), jaw crusher(max 1.5*2.1m), cone crusher(max 2.2m), Symons Cone Crusher (max 8.5 feet) and ball mill(max 6m)etc. Our company have provided hundreds of production line and thousands of machinery products to Shougang Group, Tonggang Group, Chenggang group,Tanggang, Jianlong, Zhongzhi, Tianbao, Baoli and other large mining enterprise. Our company own big technical team which is component with three generations. So we can send technical person to mine to investigate, design, install the suited production line if customers requires.
Our enterprise have a huge scale, including 100t traveling crane, vertical lathe group under 6.3m, φ250, φ220, φ200, φ160 boring machine group, high-precision large planer, large1600×8000 lathe 1500×3000 lathe, CNC wire-cut machine and other high-end accurate equipment. To make the delivery time short, Shunda invested a big capital to build its own foundry and motor factory to fit for its equipment. Therefor the common quick-wear parts and spare parts can be delivered in a week. Less than 100t products can be delivered in two months and the super-huge type machinery products delivery time is less than a half year.
Shunda has got ISO9001 and BV certification and is honored as AAA Credit Unit. In 2010, Shunda crusher ranked among "China Top 10 Crusher Brands".
