PE Series Jaw Crusher

PE Series Jaw Crusher

Jaw Crushers are used to reduce the size of many different types of materials in many applications. They are designed to exceed the primary needs of customers in the mineral processing, aggregates and recycling industries. It’s consists of many parts such as eccentric shaft, bearings, flywheels, swing jaw (pitman), fixed jaw, toggle plate, jaw dies (jaw plates), etc. A jaw crusher uses compressive force for breaking materials.
This mechanical pressure is achieved by the tow jaws dies of the crusher, one of which is stationary and other is movable. These two vertical manganese jaw dies create a V-shape crushing chamber. Electrical motor drives transmission mechanism driven swing hanging around the shaft relative to the fixed jaw do periodic reciprocating motion, The swing jaw undergoes two types of motion: one is a swing motion toward the opposite chamber side called a stationary jaw die due to the action of a toggle plate, and the second is a vertical movement due to the rotation of the eccentric. These combine motions compress and push the material through the crushing chamber at a predetermined size.

Application

PE Jaw Crushers are mostly used as the first stage of material reduction in systems that may use several crushers to complete the circuit, the Jaw Crusher has also been used as a second-stage crushing unit. Depending on the application requirements, Jaw Crushers can be used in stationary, wheeled portable and track-mounted locations. PE Jaw Crusher is well suited for a variety of applications, including rock quarries, sand and gravel, mining, construction and demolition recycling, construction aggregates, road and railway construction, metallurgy, water conservancy and chemical industry.

Mineral Processing

This crusher is used in almost all minerals and mining industries. Whether dealing with metal ore or non-metallic ore, we can offer you a solution that reduces the size, for a series of our products are available for crushing, downsizing, beneficiation with reliable design and versatility for your application. PE series jaw crushers can process 1-2,000 tons of ore per hour.

Aggregate Processing

Many infrastructure industries have a solid foundation, which is a variety of rock aggregates. Recognizing that the widespread use of these aggregates has prompted us to continuously create and improve our rock crushing equipment to help boost your production, reduce maintenance times and increase overall operational efficiency. Aggregates that are crushed from large stones are essential raw materials in construction, transportation, and other infrastructure construction. Therefore, the role of crushing equipment in the aggregate crushing production line is critical.

Our PE jaw crusher is commonly used throughout the industry to reduce the pieces into the required sizes and to impart fineness to the broken material with high quality and efficiency. It can make rocks, sandstones, river pebbles, and other materials into various granularity that meet the requirements of construction sand with high compressive strength, being more in line with building requirements, and characteristic of improving building quality.

Coal Processing

PE jaw crusher is widely used in coal mine operations and attractive to customers because of its uniform end granularity, lower noise, less dust, and less pollution. Under strict environmental regulations, a good deal of coal mine projects has been suspended due to large pollution, which has seriously hindered the development of mining plants, resulting in low efficiency in major mining areas.

However, we have actively responded to the call for environmental protection by using advanced technologies and new materials to manufacture this crusher to meet national environmental standards. Coupled with PE’s superior discharge size and simple operation characteristics, our company has been chosen by many users.

Recycling

The rapid development of society has led to the production of many construction wastes. The original construction waste is not treated, not only occupies the land, but also causes pollution of rivers. The application of the crusher not only solves environmental pollution but also brings a high economic benefit for investors by recycling the construction waste into valuable materials.

Operation & Maintenance 

– Installation

The jaw crusher is a large crusher installed and receives no-load testing in the manufacturer’s workshop. However it is disassembled into components for transport. When receiving the product, the user shall check carefully the components with the packing list to identify and remove problems that could be caused during transport.
1. To avoid violent vibration caused in operation, this crusher shall be installed on reinforced concrete foundation. The weight of the foundation shall be roughly 8 to 10 times that of this crusher. The depth of the foundation shall be greater than that of the frozen land at local. The positions of anchor bolts for the crusher and motor as well as other dimensions can be found from the foundation drawing. Nonetheless, the foundation drawing may not be used as construction drawing. For these anchor bolts, holes shall be made in the foundation. Grouting in these holes shall be performed after anchor bolt placement. The elevation and size of the discharge chute shall be determined on site according to the discharge process.
2. After the grout hardens, tightening the nuts to anchor bolts. While doing so, measure the levelness of this crusher with a leveling gauge. Along the width of front wall of the framework, the levelness deviation shall be controlled to be less than 2mm. Framework levelness inspection is particularly important to prevent possible skewness of charge port which could cause charge from only one side and bring damage to the crusher because of uneven load.
3. When installing the motor, check the distance between it and the crusher, and whether its pulley corresponds to the crusher pulley so that all the V-belts run effectively in coordination.
4. The size of discharge port shall be adjusted according to granularity of materials and capacity of the crusher. Release the tension spring, adjust the discharge port size, and then tighten the tension spring to prevent the elbow plate detachment. For details, refer to the Component Adjustment Section.

– Lubrication

(1) To ensure normal operation and extend service life of the crusher, regular lubrication shall be performed.
(2) Grease in the bearing block shall be replaced every 3 to 6 months. Before adding grease, clean carefully raceways of roller bearing by using clean gasoline or kerosene, with the drain hole at the bottom of bearing clock open. Add grease to 50% to 70% of the bearing block capacity.
(3) Grease used for this crusher shall be selected according to altitude and climate. Generally, calcium base, sodium base, or calcium- sodium base grease may be used. And thick grease may be diluted with light oil.
(4) Between the toggle plate and toggle plate pad, it is enough to apply proper amount of grease during assembly and inspection.
(5) For reliable and quick application of grease to lubrication points, the lubrication mechanism is utilized (there are four lubrication points in this crusher, i.e. the four bearings). For lubrication time, refer to the drawing.

– Operation

1. Preparation before starting
1.1. Check the lubrication of main bearings in right amount, toggle plate and pitman in right position
1.2. Check and confirm all the bolts are fastened
1.3. Check the counterweight in good condition and right position
1.4. The belts are well installed, and they are in good condition.
1.5. Correct the protecting devices if there are not in good condition.
1.6. Check whether there are any materials in the crushing groove and clear it.
1.7. Check whether the gasket is installed correctly or pressed tightly.
2. Start the crusher
2.1. Start the machine only after making sure that the machine and transmission part can work in good condition.
2.2. This machine should start with No-Loading.
2.3. Stop the machine immediately if any uncommon fact occurs. Start the machine only after checking and correcting.
3. Operation
3.1. Start feeding after checking that the machine works well.
3.2. Feed the material uniformly into the machine, and avoid feeding material from one side only or feeding to overload.
3.3. Stop feeding before shutdown the machine. Shut the motor down after the crusher cavity is clear.
3.4. Stop the motor immediately if the crusher is blocked due to material clogging in the cavity
3.5. Jaw dies can be installed upside down once the lower half of jaw dies is not in good condition
3.6. Check all fixed parts before starting to use and tighten all the bolts and screws if they are loose.

– Discharge Setting

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher.
1. Measuring Discharge Opening:
1.1. Measure distance at bottom of jaws at the point of the crushing cycle when bottom of jaws are closet together.
1.2.  Turn flywheel so that counter weights are parallel with movable jaw
1.3. Using a piece of lumber as a ‘’feeler gage’’ check the distance between the valley of the corrugations on one jaw to the crown of the corrugations on the other
2. Adjusting the discharge side opening:
2.1. Loosen nuts before making adjustment
2.2. Loose tension if crusher is to be adjusted for finer crusher.
Crusher must be adjusted when it’s stopped and the chamber is empty. Never close crusher discharge opening to less than minimum opening. Close crusher opening to less than recommended will reduce capacity of crusher and cause premature failure of shaft and bearing assembly.
To compensate for wear on toggle plate, toggle seat, pitman toggle seat and jaws additional shims must be inserted to maintain the same crusher opening. The setting adjustment system is designed to compensate for jaw plate wear and to change the closed side setting of the jaw crusher. The setting adjustment system is built into the back frame end.

– Troubleshooting

1. Movable jaw does not rotate while flywheel is rotating
2. Crushing plate shakes and makes collision noise
3. Thrust plate support makes collision noise or other abnormal noise
4. Flywheel comes loose
5. Increased granularity of crushed products
6. Crushing cavity blockage, resulting in current of main motor exceeds normal operation current
7. Excessively high bearing temperature
