EC Series Jaw Crusher

Working Principle:

The EC series jaw crusher takes the eccentric shaft + elbow plate as the core transmission mechanism, which transforms the rotational movement of the motor into the recirrecing swing of the moving jaw. Through the periodic extrusion of the moving jaw and the fixed jaw, it realises the efficient coarse crushing operation of hard rock, ore and other materials. At the same time, through modular adjustment and shock absorption design, it takes into account the crushing efficiency, The accuracy of the finished product and the stability of the equipment.

Product Parameters:

Product Instructions for Use:

1. Discharge port adjustment: The adjustment of the discharge port of the Planet EC series crusher is done through the adjustment screw on both sides of the crusher, and the discharge port is stepless adjustment. When adjusting the discharge port, the two adjustment screws must be adjusted synchronously, and only one side of the screw is not allowed to be adjusted.
2. The order of start-up and shutdown:
   1. Start-up order: start the discharge device – start the crusher – start the feeding device
   2. Shutdown order; stop the feeding device – stop the crusher – stop the discharge device

3. Correct feeding: The correct feeding should fall vertically into the crushing cavity. The feeding should not impact the jaw head. The feeding particle size must be controlled within the specified range. Excessive feeding will greatly reduce the capacity of the crusher. When the feed volume reaches 2/3 of the crushing cavity, the crusher has the highest efficiency.

Product Maintenance:

1. Lubricate once every 40 working hours), see Section 5.3.3 of the manual for the required amount of grease.
2. Lubricate the discharge port adjustment device and check the condition of its rubber cover (mechanical adjustment of the discharge port),
3. Check the wear of the cheek plate and replace it if necessary.
4. Check the elbow plate in the middle, the straightness and whether there are cracks.
5. Check the elbow seat and rubber seal, and clean the surface of the elbow seat if necessary.
6. Check the tightening of the frame fixing bolt.
7. Check the condition of the flywheel.
8. Check the wear of rubber shock-absorbing pads

Application scenarios:

EC series jaw crushers are mainly used for coarse crushing operations in mine and sand production. They are suitable for all kinds of medium to high hardness ores and rocks, such as granite, basalt, river pebbles, iron ore, etc. The equipment has strong crushing capacity and stable operating performance, which is suitable for the primary crushing of large materials.

(1) In the sand and stone aggregate production line, the EC series jaw crusher is usually used as the first crushing process equipment. It is located at the front end of the whole production line. It is responsible for crushing large pieces of raw ore or blasting stone to medium particle size, providing suitable feeding conditions for subsequent cone crushers or counter impact crushers. It is the whole production The basic equipment for the stable operation of the production line.

(2) It is also widely used in mining, cement building materials, highway and railway construction and metallurgical industries. It is especially suitable for coarse crushing conditions that require high output and continuous operation. It is one of the core coarse crushing equipment in large-scale sand and stone production systems.

FAQ:

Q：What is the position of the EC European version jaw crusher in the production line? What role does it play?

A：EC series European version jaw breaker is the first-level coarse crushing core equipment of the whole sand and stone production line. It is arranged at the front end and is responsible for the initial crushing of large pieces of raw stone. The subsequent docking of cone breaker, counterattack breaker, vibrating screen and other equipment is the first main model of fixed and mobile production lines, which determines the basic production capacity and stability of the whole production line.

Q： Why do large-scale projects prioritise EC European version jaw break and not ordinary PE jaw break?

A：The EC European version of the model is a heavy-duty, intelligent and large-capacity upgraded version of the jaw breaker. Compared with ordinary PE models, the fuselage is thicker, the crushing force is greater, the feed volume is higher, and the operation and maintenance are more convenient. It is suitable for 24-hour continuous heavy-load production, and the production capacity is 20%-30% higher than that of ordinary jaw fractures of the same specification. It is the first-breaking equipment of modern large-scale sand and stone factories.

Q： What are the core advantages of the European version of the EC series jaw crusher?

A：The EC European version of the jaw breaker has four core advantages: heavy-duty overall fuselage, modular structure, hydraulic adjustment, small operation vibration, and large production capacity. The feed particle size is large, the crushing ratio is high, and the finished product is uniform. It adopts an integrated rack design, which is impact-resistant, not easy to deform, easy to maintain, extremely low downtime rate, and lower comprehensive production cost.

Q： How to select the EC series jaw crusher?

A：The selection is mainly based on the hardness of the material, the maximum feed particle size and the production requirements. Large-scale mining projects usually choose high-capacity models to meet continuous production needs, while medium-sized sand and stone factories choose standard models. During the selection process, it is necessary to match the design in combination with the configuration of the whole crushing production line to ensure the stable operation of the system.

Q： Are EC jawbreak accessories in stock? Can the supply be stable for a long time?

A：The whole series of EC European version jaw-breaking conventional consumable parts and whole machine accessories are in stock all year round, and can be shipped quickly. As a source production factory, it supports large-scale supply throughout the year, foreign trade agent’s fixed-point stocking, and long-term mining of mines. The source of goods is stable and the quality is unified.

Q： How to transport the EC series jaw crusher?

A：The equipment is packaged in standard protection before leaving the factory, and the container or bulk cargo transportation mode is adopted according to the model, and the anti-rust and anti-shock reinforcement treatment is carried out. We can assist customers in completing the shipping and customs clearance process to ensure the safe delivery of equipment to the project site.
