Jaw crusher PE500x750 (about 20x30 inches)

1. Technical data of jaw crusher PE500x750

Model: PE500x750(about 20 x 30 inches)

Max feed size: less than 425mm

Discharge opening range: 50 to 100mm

Capacity: 40 to 110 tons pe rhour

Motor: 6 pole 55 KW, frequency 50Hz or 60Hz

Weight: about 11.73 tons

2. Main shaft of jaw crusher PE500x750

Main shaft must be forging part, it guarantee the safety of the main shaft, even with the hardest stones, there is no damage of the main shaft during jaw crusher working.

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. Forged parts are widely used in mechanisms and machines wherever a component requires high strength.

Never use a steel rod to make the shaft, it will be easily damaged in case of hard stones or unbreakable materials.

3. Jaw plates & cheek plates

There are different types of teeth for the jaw plates, some for coarse crushing, some for medium crushing, typical material of the jaw plates is ZGMn13Cr2 or ZGMn18Cr2. Depends on different types of rocks, the jaw plates will be different as well.

Heavy duty jaw plates are always more wearable, Deya Jaw crusher PE500x750 applies mobile jaw plates with thickness of 130mm, while stationary 110mm.

Cheek plates are important to protect the main frame, it is wearing parts, thickness of cheek plates 30mm.

Please keep in mind that the jaw plates can be used up side to down side, and down to up after wearing.

4. Main frame of jaw crusher PE500x750

There are two types of main frame, casting steel and steel plate welding. Both types are good. In a mobile jaw crusher, weight should be reduced when install the jaw crusher to a trailer, steel plate welding frame is preferred due to the low weight.

Bearing seats of both sides must be perfectly processed to guarantee the same level, it is important factor. If not in the same level, it will cause great trouble during jaw crusher working, bearings temperature will increase thus may cause damage.

5. Bearings

There are 4 bearings on the jaw crusher PE50x750, qualified bearings are always recommended, in China top brand bearings are good enough for normal jaw crusher. Deya Machinery jaw crusher bearings with LYC or ZWZ brand, they are the top brands in China.

6. Motor and motor control panel

Top brand motor like Yu tong, Wan Nan, Liu An are recommended. Cable with correct connection, these motors are stable running without any problem in at least 10 years.

Motor control panel is necessary for the jaw crusher, it protect the motor during starting and stop stages. Deya jaw crusher PE500x750 use YE3 energy efficiency rating grade 6 pole motor, power 55KW. The control panel electrical parts should a higher level like 75KW, it is capable for the jaw crusher motor.

7. Jaw crusher PE500x750 assembly process

A. Install stationary jaw plate and cheek plate

B. Install bearings to the mobile jaw plate

C. Install the adjusting seat to the main frame

D. Install the mobile jaw plate to the main frame

E. Install the flywheels

F. Intall the toggle plate and adjusting plates at back

G. Install the pull rod and springs

H. Connect the V-belts to motor and flywheel

I. Connect the motor to control panel

J. Empty testing, 5 hours non stop testing, in any case the bearings temperature no more than 70 ℃, deya jaw crusher bearings temperature within 28 to 32 ℃ during testing. It is in perfect running condition. During the testing, abnormal sound is not allowed, it should run smoothly with low noise.
