A jaw crusher’s main components are a fixed jaw plate and a movable jaw plate. During operation, the motor primarily drives a belt and pulley, which, via an eccentric shaft, moves the movable jaw up and down, changing the angle between the toggle plate and the movable jaw. When the movable jaw approaches the tooth plate of the frame, it crushes the material. When the tooth plate moves away, the crushed material in the crushing chamber is automatically discharged by gravity, allowing continuous operation. What should I do if my jaw crusher’s discharge is uneven? Regular routine inspections of the crusher can help identify problems early. When the crusher’s discharge particle size is uneven, carefully identify the cause and promptly troubleshoot it to avoid the inconvenience of machine downtime. Uneven discharge particle size from a jaw crusher is primarily caused by the following: 1. The motor wiring is incorrectly positioned, causing the main unit to move in the opposite direction (i.e., the movable jaw rotates clockwise), or the motor is connected in a star configuration instead of a delta configuration. 2. The jaw plate is misaligned, causing the tooth tops to align with each other. 3. Excessive clearance between the...

When using a sand making machine, please note the following points to reduce wear and extend its service life! 1) Do not over-iron the crusher; 2) Do not start or stop the machine with material in the machine; 3) Do not operate the machine with overcurrent or low voltage; 4) Do not continue to operate the machine if it makes unusual noises; 5) Do not inspect or adjust the machine while it is running; 6) Do not feed the machine off-center; 7) Do not allow large pieces of material exceeding the maximum feed size specified by the equipment to enter the crushing chamber; 8) Do not operate the crusher if the lubricating oil is below 15°C; 9) Do not operate the crusher if the lubricating oil return temperature exceeds 60°C; 10) Stop operating the crusher if the lubricating oil filter is clogged; 11) Stop operating the crusher if the lubrication station alarm light is on; 12) Stop operating the crusher if the impeller is unbalanced; 13) For sand making machines with dual motors, do not start one motor before starting the other; 14) The lubrication station and main machine control cabinets should be interlocked to operate the crusher.

After long-term use, machinery like sand making machines will inevitably experience malfunctions, so daily maintenance is essential. Among these, wearing parts are crucial for sand making machine maintenance! The following are several wearing parts in a sand making machine: 1. Bearings: These bear the entire load of the sand making machine. Therefore, regular lubrication and cleaning directly impact the sand making machine’s service life and operating speed. 2. Rotor: This component drives the sand making machine’s high-speed rotation. During production, the top, inner side, and lower edge of the rotor are prone to wear. Therefore, it is important to maintain balanced rotor operation. Otherwise, vibration will occur, increasing wear on the rotor and rotor bearings. 3. Impact block: The wear of the impact block in a sand making machine is closely related to the material selection and the properties of the material. Ensure that the sand making machine and impact block are matched, and the hardness of the crushed material must be within the sand making machine’s tolerances. 4. Impeller: Maintain counterclockwise rotation. Otherwise, adjust the motor wiring position. Feed the material evenly and continuously according to size. Otherwise, the impeller will become unbalanced and wear the impeller. Always stop...

If a cone crusher is used for limestone processing, which has low hardness, dust will be generated and yield will be low. This is because, while cone crushers offer high crushing force and high wear resistance, they are not suitable for processing medium-hard, brittle materials like limestone. For limestone processing, it is recommended to use a jaw crusher for coarse crushing and an impact crusher or hammer crusher for medium and fine crushing. Using the impact principle, the finished limestone is cubic, multi-angled, and has low dust content. Using an impact crusher for limestone processing has three advantages: 1. High efficiency: The rotor back plate can withstand high rotational inertia and impact crushing forces, improving crushing efficiency. 2. Low maintenance: Impact crushers are made of high-quality alloy materials, which enhances wear resistance and effectively reduces maintenance time. 3. High product utilization: The gap between the impact plate and the hammer is adjustable, allowing adjustments to meet different production needs. This effectively controls the output particle size, resulting in excellent finished product shape, low dust content, and high value. Limestone Crusher Price How much does a limestone crusher cost? The price ranges from approximately 100,000 to 300,000 yuan, primarily influenced by...

Crusher is an essential piece of equipment for manufactured sand production plants. There are many different types of crushers, so how do you choose one? And what is the price? Crusher prices vary depending on the model, material, and process. Because the size of the raw material and production capacity required vary depending on individual needs, production line configurations also vary. This article uses a 100-ton-per-hour production capacity as an example to share the investment budget for common crushing production lines. 1. Jaw Crusher + Cone Crusher/Impact Crusher + Sand Maker This is a complete crushing production line, and the budget is correspondingly higher. It is suitable for larger raw materials with finer output. This production line can directly process the raw material using a jaw crusher, cone crusher/impact crusher, and sand maker after blasting. Stones under 1.2 meters in size can be fed directly into the jaw crusher for coarse crushing, followed by a cone crusher/impact crusher for finer crushing, and then into a size of less than 5 centimeters before entering the sand maker for shaping. 2. Jaw Crusher + Cone Crusher/Impact Crusher This production line is suitable for customers with larger raw materials and require output in...

1. Applications where a cone crusher is more suitable Material Characteristics: When limestone has a high hardness (e.g., compressive strength > 200 MPa) or contains a high level of impurities, the wear-resistant components of a cone crusher (e.g., crushing wall and mortar wall) are more durable. Production Requirements: a. Large-scale production lines require stable secondary or tertiary crushing, such as mining projects with annual output exceeding one million tons. b. Applications where high particle size uniformity is required and excessive fines production is undesirable (e.g., for roadbed stone). Environmental Requirements: Low operating noise, suitable for areas with strict environmental requirements. 2. Applications where an impact crusher is more suitable Material Characteristics: Limestone has a medium hardness (compressive strength < 200 MPa), few impurities, and a relatively brittle texture, making it suitable for impact crushing. Production Requirements: a. Applications where a high-fineness product is desired (e.g., manufactured sand production) or where cubic particles are required (e.g., commercial aggregate). b. Applications where flexible particle size adjustment is required in small or medium-sized production lines (impact crushers can quickly change the output particle size by adjusting the gap between the impact plates). Additional Advantages: The crushing process inherently shapes the sand, reducing subsequent...
