What are the internal structure of the compound crushers?

Compound crushers, also known as composite crushers or combination crushers, are designed to crush materials efficiently by combining the advantages of both hammer crushers and impact crushers. They typically consist of several main components, each serving a specific function within the internal structure of the crusher.

Main Frame: The main frame of the compound crusher provides structural support and houses the other components of the crusher. It is usually made of welded steel plates or cast steel for strength and durability.

Rotor Assembly: The rotor assembly is a key component responsible for the crushing action in the compound crusher. It consists of a rotor shaft, rotor discs, and hammer bars or impact elements. The rotor rotates at high speed, impacting the material fed into the crusher chamber.

Crushing Chamber: The crushing chamber, also known as the crushing cavity or crushing chamber, is the space where the material is crushed by the rotor. It is typically lined with wear-resistant liners to protect the crusher housing from abrasion and wear.

Feed Hopper: The feed hopper is located above the crushing chamber and serves as the entry point for the material to be crushed. It allows for controlled feeding of the material into the crusher, ensuring efficient operation and preventing overloading.

How does briquetting press work?

A briquetting press, also known as a briquette press or briquette machine, is a device used to convert various types of biomass, metal, or other materials into uniform, shaped briquettes. These briquettes are typically cylindrical in shape and can vary in size depending on the specific requirements of the application.

How does briquetting press work

briquetting press

Material Feeding: The raw material, which could be biomass (such as wood chips, sawdust, or agricultural residues), metal chips, or other types of material, is fed into the briquetting press. This can be done manually or through automated feeding systems, depending on the scale and complexity of the operation.

Compression Chamber: Inside the briquetting press, there is a compression chamber where the raw material is compacted under high pressure. This pressure is applied using a hydraulic system, mechanical system, or a combination of both.

Compression and Briquette Formation: As the raw material enters the compression chamber, it is subjected to high pressure, which compresses it into a dense mass. The pressure forces the material to bind together, forming briquettes of the desired shape and size. The shape of the briquettes can vary depending on the design of the press and any additional shaping attachments.

briquetting press

Ejection or Discharge: Once the briquettes are formed, they are ejected from the press either manually or through automated ejection systems. In some cases, the briquettes may need to be cooled or cured before they are ready for use or further processing.

What are the features of the flip flop screen?

A flip flop screen, also known as a flip flow screen or flip-flop waste separator, is a type of screening machine used in various industries for the separation of materials based on size and composition. It’s particularly useful for handling materials that are difficult to screen using conventional vibrating screens, such as wet, sticky, or highly variable materials.

The design of a flip flop screen typically involves two separate screening decks that are arranged in parallel and connected to a system of cross beams. Each screening deck consists of alternating polyurethane flip flow panels and conventional screening panels. The flip flow panels have a unique design with flexible polyurethane fingers that move independently when subjected to vibration.

flip flop screen

The operation of a flip flop screen involves a combination of linear and elliptical vibration, which causes the flip flow panels to flex and relax rapidly. This dynamic motion helps to prevent clogging and blinding of the screen surface, allowing the material to pass through more efficiently. The flexible fingers of the flip flow panels also provide excellent self-cleaning action, further enhancing the screening process.

Flip flop screens features

High Efficiency: Flip flop screens are capable of achieving high screening efficiency, even with difficult-to-screen materials, thanks to their unique design and dynamic motion.

How does a motor vibration work?

Motor vibration refers to the mechanical oscillations generated by an electric motor during operation. These vibrations are caused by various factors, including the rotating components of the motor, imbalance, misalignment, mechanical wear, and resonance within the motor and surrounding structures.

Vibration motor working principle

Vibration motor

Rotating Components: Electric motors consist of rotating components such as the rotor (armature) and the stator. When the motor is powered, these components rotate at high speeds, generating centrifugal forces.

Imbalance: Imbalance occurs when the mass distribution of the rotating components is not uniform. Even minor imbalances can lead to significant vibrations. Imbalance may result from manufacturing variations, wear and tear, or improper installation.

Misalignment: Misalignment between the motor shaft and connected equipment, such as pumps or fans, can cause vibration. Misalignment can occur due to poor installation, thermal expansion, or mechanical stress.

Mechanical Wear: Wear and tear on motor bearings, shafts, and other components can lead to increased friction and vibration. Over time, components may degrade, leading to increased vibration levels and reduced motor efficiency.
