Shanghai Jingxiang Heavy Machinery Co.,ltd. - Crushing Machines

Hammer is made of high chrome; liner board is made of wearable materials;specially designed tooth impact plate;more suitable for crushing hard rock, high efficiency, low consumption;final products is cubic, discharge opening is adjustable;make the crushing flow chart simple.

1. Simple structure and low operating cost; 2. High crushing ratio with low consumption; 3. Function of fine crushing and crude grinding; 4. Slightly influenced by moisture content of material, and the max moisture content is about 8%; 5. More suitable for crushing mid-hardness and hardness materials; 6. Cubic shape of final products, high density of piling up and low iron pollution; 7. More wearable and easier maintenance; 8. Low working noise (lower than 75 decibel) and light dust pollution.

1.world-level manufacturing technology is adopted, and highest-level raw material is used.2. central lubricating device are installed on the machine, so the bearing is easy to be lubricated.3. adjustment of the discharge part is more convenient.the adjustment methods: gasket adjustment, hydraulic assistant adjustment, wedge block and wedge hydraulic adjustment.4. more advanced movable jaw assembly lengthens life of crusher. movable jaw assembly is made from cast piece with high-quality, is driven by two large flying wheels which are made from cast steel. moreover, heavy eccentric shaft is processed by forged mold. all of these make the jc series jaw crusher extremely reliable.5. integral cast steel structure is adopted for bearing seat. integral cast steel bearing matches well with the crusher frame, at the same time, radial strength of the bearing seat is highly strengthened. however, the separate bearing seat does not have this advantage. 6. finite element analysis technology is adopted to make the crusher much stronger.7. crusher chamber adopts "v" structure which could make actual feed width comply with the nominal one.

1. Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation. 2. Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increases productivity. 3. Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance. 4. Over-vibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it. 5. Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally. 6. Special feed opening structure makes it possible that center feeding and ring feeding comes together, in order to meet requirement of different stones. In addition, this equipment can not only crush stone, but also iron.
