How does the compound cone crusher work?

A compound cone crusher is a type of cone crusher that combines multiple crushing actions into one unit, making it suitable for crushing hard, medium-hard, and abrasive materials. The working principle of a compound cone crusher involves several components and processes, which can be summarized as follows:

Working principle of compound cone crusher

compound cone crusher

Crushing Chamber Design: The geometry of the crushing chamber plays a crucial role in determining the crusher’s performance. A compound cone crusher typically has a steep crushing chamber with a long parallel zone for the primary crushing action and a shorter parallel zone for secondary or tertiary crushing.

Eccentric Shaft and Bearing Assembly: The eccentric shaft is mounted on the main frame of the crusher and is driven by the motor through a belt drive system. As the eccentric shaft rotates, it causes the mantle to move in a circular motion, crushing the material against the concave liner.

Mantle and Concave Liners: The mantle is a movable component that gyrates within the fixed concave liner. The crushing action occurs when the mantle moves closer to or away from the concave liner, crushing the material between them. The gap between the mantle and concave liner, known as the crushing chamber, can be adjusted to control the size of the crushed product.

Hydraulic System: Many modern compound cone crushers are equipped with a hydraulic system that allows for easy adjustment of the crushing chamber and setting changes. Hydraulic cylinders are used to apply pressure to the main shaft, adjusting the position of the mantle relative to the concave liner.

Feed Distribution Plate: The feed distribution plate distributes the incoming feed material evenly across the entire width of the crushing chamber, ensuring efficient utilization of the crushing surfaces and preventing uneven wear.

How does the conveyor work?

A conveying machine, also known as a conveyor, operates on a relatively simple principle: it moves items or materials from one location to another. The specific working principle can vary depending on the type of conveyor and its design, but here’s a general overview:

Conveyor working principle

conveyor

Belt Conveyors: These are among the most common types of conveyors. They consist of a continuous belt that rotates around two or more pulleys. The belt is typically made of rubber, PVC, or other materials with high friction properties. As the belt moves, it carries items or materials placed on top of it from one end to the other. The rotation of the pulleys drives the movement of the belt.

Roller Conveyors: Roller conveyors use rollers instead of a continuous belt to move items along a path. The rollers are mounted on a frame and can be powered or gravity-driven. Powered roller conveyors use motors to rotate the rollers, while gravity roller conveyors rely on the force of gravity to move items downward along a slight incline.

How to maintain robot bearings

Robot bearings are specialized bearings designed for use in robotic applications. These bearings play a crucial role in ensuring smooth and precise motion control, which is essential for the proper functioning of robotic systems. Maintaining robot bearings is essential for ensuring the optimal performance, longevity, and reliability of robotic systems.

Robot bearings maintenance tips

Regular Inspection: Perform routine visual inspections of the robot bearings to check for signs of wear, damage, or contamination. Look for issues such as corrosion, pitting, rust, cracks, or abnormal wear patterns.

Lubrication: Proper lubrication is critical for reducing friction, preventing wear, and extending the lifespan of bearings. Follow the manufacturer’s recommendations for the type and frequency of lubrication. Use high-quality lubricants compatible with the bearing materials and operating conditions.

Robot bearings

Cleanliness: Keep the surrounding environment clean to minimize the risk of contamination entering the bearing system. Dust, dirt, debris, and other contaminants can accelerate wear and cause premature failure. Regularly clean the robot and its components, paying attention to areas around the bearings.

Sealing: Ensure that the bearings are adequately sealed to protect them from moisture, dust, and other contaminants. Check the seals regularly for damage or degradation and replace them if necessary. Proper sealing helps to maintain lubrication integrity and prevent premature failure.

Alignment: Misalignment can lead to uneven loading, increased friction, and premature wear of bearings. Periodically check the alignment of the robot components, including the bearings, shafts, and mounting surfaces. Adjust as needed to ensure proper alignment and smooth operation.

Temperature Control: Monitor and control the operating temperature of the robot bearings within the recommended range. Excessive heat can degrade lubricants and cause thermal expansion, leading to bearing failure. Implement cooling measures if necessary, such as ventilation or thermal insulation.

What is a welding positioner

A welding positioner is a mechanical device used to manipulate and hold a workpiece in the optimal position for welding. It allows welders to work more efficiently by rotating or tilting the workpiece to the desired angle, making it easier to access different areas for welding without having to reposition themselves constantly.

Welding positioners come in various shapes and sizes, ranging from small tabletop units for light-duty welding to large, heavy-duty units capable of handling massive workpieces in industrial settings. They typically consist of a base, a rotating mechanism, and a fixture to hold the workpiece securely in place. Some advanced positioners may also include tilting capabilities to achieve even more precise positioning.

Using a welding positioner can improve weld quality, increase productivity, and reduce fatigue for the welder by providing better access to the welding area and allowing for consistent weld bead placement.

Welding positioner type

​welding positioner

Horizontal Positioners: These positioners rotate the workpiece around a horizontal axis. They are often used for welding cylindrical or round workpieces such as pipes, tanks, and vessels.

Vertical Positioners: These positioners rotate the workpiece around a vertical axis. They are suitable for welding flat or plate-like workpieces and are commonly used in industries such as shipbuilding and construction.

Headstock-Tailstock Positioners: These positioners consist of a headstock (which holds one end of the workpiece) and a tailstock (which supports the other end). They allow for rotation and tilting of the workpiece, providing greater flexibility in positioning during welding.

Turntable Positioners: Turntable positioners are like rotating platforms that can hold and rotate the workpiece. They are often used for smaller workpieces and in situations where precise rotation is required.

Manipulators: Manipulators are more complex positioners that combine vertical and horizontal movement capabilities. They can move the welding torch in multiple directions around the workpiece, allowing for welding in various positions and angles.

Automatic Welding Positioners: These positioners are equipped with automation features such as programmable controls, sensors, and robotic arms. They are used in automated welding processes where precise control and repeatability are essential.
