PE/PEX Jaw Crusher

Working Principle:

The motor drives the eccentric shaft through the slot wheel through the triangular belt, so that the moving machine moves according to the adjusted trajectory, so as to break the materials in the crushing cavity. The rack is composed of the front wall, the back wall and the left and right side panels. On the wall in front of the rack, the gear plate is tightened with wedge bolts 6. The tooth plate is divided into three pieces. The size of the upper and lower pieces is the same, and the length of the middle block is relatively small, so as to adapt to the fast wear in the middle of the tooth plate and easy replacement, and the upper and lower pieces continue to be used. The left and right side walls of the rack are equipped with side guards 7 to prevent wear of the rack wall. ·

The box-type cast steel piece of Dongying is equipped with a Ying plate on the front and a guard plate on the top of the front. The upper part is suspended on the frame with the eccentric shaft and roller bearing, and the lower part is supported on the elbow plate and in rolling contact. There are flywheels and slot wheels at both ends of the eccentric shaft.

The other end of the elbow plate is also in rolling contact with the adjustment seat 8. In addition to supporting the movement, the elbow plate also has an insurance effect when foreign objects that cannot be broken from outside enter the crushing cavity and the load of the crusher increases, it also has a safe effect, that is, self-breaking. So as to protect other parts from damage.

The adjustment seat is suspended on the back wall of the rack with two adjustment screws through the right-angled iron. The angle between the elbow plate and the movement can be fine-tuned by the gasket. When the discharge port needs to be adjusted, the adjustment gaskets of different thicknesses can be inserted through the adjustment seat of the oil-pressure roofing machine to achieve the purpose of adjustment.

Product Parameters:

Product Instructions for Use:

1. After the crusher is running normally, it can start feeding.
2. Crushed materials should be evenly added to the crushing cavity and should avoid side feeding to prevent load mutation or unilateral load surge.
3. Under normal operation, the temperature rise of the bearing should be controlled within 35℃, and the highest temperature should not exceed 70℃. If the temperature exceeds 70℃, immediately shut down for inspection, troubleshoot the abnormal cause and deal with it in time.
4. Before parking, you should stop adding. After the crushed material is completely discharged in the crushing cavity, the motor can be turned off.
5. During crushing, if the stop is caused by material blockage in the crushing chamber, the motor should be turned off immediately. The material must be removed before it can be started again.
6. After one end of the jaw plate is worn out, it can be used up and down.

Product Maintenance:

(1) According to the working condition of the lubrication point, pull the lubrication handle in time to refuel the lubrication point to ensure the normal operation of the machine and extend the service life.

(2) The grease used in this machine should be determined according to the place of use of the machine, temperature and other conditions. Generally, calcium-based, sodium-based or calcium-sodium-based grease can be used.

(3) The grease filling amount of the bearing seat is 50%~70% of its volume. When changing the oil, clean the roller bearing track with clean gasoline/kerosine.

(4) Cut off the power supply during maintenance, and use the original factory-aded accessories for consumable parts. Long-term deactivation needs to be cleaned and rust-proof.

Application Scenarios：

As the first crushing core equipment of the sand and stone aggregate production line, PE coarse jaw crusher and PEX fine jaw crusher are widely adapted to multi-industry crushing conditions around the world:

(1) Mining industry: iron ore, copper ore, manganese ore, gold ore, limestone, granite, basalt, river pebble and other hard ores coarse crushing and medium fine crushing operations, compressive strength ≤320MPa materials can be processed stably;

(2) Construction sand and stone aggregate factory: highway, railway, water conservancy infrastructure, commodity concrete mixing station sand and stone raw material crushing, which can be combined with cone breaking and vibrating screen to form a complete fixed/mobile crushing production line;

(3) Resource treatment of construction waste: recycling, crushing and recycling of waste concrete, bricks and stones and steel slag;

(4) Metallurgy, chemical industry, cement and refractory materials industries: raw material pretreatment, rough processing of block materials;

(5) Small and medium-sized personal mines and village sand and stone processing factories: single-machine small-capacity on-site crushing operation, flexible installation and simple operation and maintenance.

FAQ：

Q: How to choose the appropriate PE/PEX model according to your own mine conditions?

A: We mainly select accurately according to the three core working conditions: ore hardness, maximum feed size, and hourly production capacity requirements. For granite, basalt, iron ore and other hard and high-grinding materials, priority is given to the heavy-duty fuselage PE/PEX model; limestone, coal and other medium and soft materials, the standard model can meet the production. Our company can provide one-on-one condition selection and the overall layout of the production line free of charge.

Q: What materials can be crushed by PE/PEX jaw crusher? What is the upper limit of material hardness?

A: This machine can handle all kinds of ores and stones with compressive strength ≤320MPa, suitable for the vast majority of mines and infrastructure materials. It is widely used in the crushing of granite, basalt, river pebbles, limestone, iron ore, copper ore and other ores. At the same time, it can be used for construction waste, steel slag and other solid waste recovery and crushing operations, and adapts to multi-scenario production needs.

Q: What is the biggest advantage of your PE/PEX jaw break compared with your peers? Why is it more durable?

A: Our company is a physical factory of cast steel for more than 30 years, and the whole process of equipment is produced independently without outsourcing. The whole machine adopts a full set of processes of 3D scanning modelling, precision melting and casting, professional heat treatment and heavy hydraulic correction, with a 1.25-4-metre large CNC lathe and 1,800 tons of heavy hydraulic correction equipment. The whole fuselage is thickened and reinforced, which completely eliminates the deformation of casting and heat treatment. The heavy-load operation is not deformed, the vibration is small, the failure rate is low, and the service life of the whole machine is far more than that of ordinary equipment.

Q: Do you supply the original factory consumable parts for a long time? How about the adaptability of accessories?

A: Our company independently produces the original consumable parts of the whole series of PE/PEX jaw crusher, including tens of thousands of accessories such as high-manganese steel jaw plate, edge guard plate, lining plate, eccentric shaft, bearing, etc. All accessories are processed from the same factory and source, with accurate size, 100% adaptability, wear-resistant and impact-resistant, and longer service life. Support long-term bulk stocking and quick replenishment, and continue to solve the supply problems of equipment maintenance and accessories for domestic and foreign customers.

Q: Is the threshold for agency cooperation high? Do you support small-batch trial orders?

A: There is no high franchise fee, the cooperation threshold is flexible, and it supports small-batch trial orders, single-machine goods, and bulk purchase of accessories. Long-term cooperative agents can enjoy better settlement policies and supply priorities, which is suitable for all kinds of overseas mining equipment dealers and local engineering service providers to cooperate.

Q: What trade mode does the company adopt? Is the packaging of export logistics guaranteed?

A: Our company uniformly adopts FOB trade terms, and is responsible for the whole process of equipment rust prevention, waterproof reinforcement, export wooden box packaging, domestic transportation, customs declaration and port loading. Large-scale equipment is reinforced and packaged separately, and small accessories are independently moisture-proof and packaged to effectively avoid collisions and rust in sea transportation. At the same time, boxing photos, shipping videos and a full set of customs clearance documents can be provided to ensure smooth overseas customs clearance.

Q: What are the technical service guarantees after the after-sales service of the equipment?
