Keywords

💡mini jaw crusher

A mini jaw crusher is a compact version of the heavy machinery used to crush rocks and minerals. It is an essential piece of equipment in mining and construction, where it helps to reduce large rocks into smaller, more manageable pieces. In the video, the presenter is testing a new mini jaw crusher, highlighting its portability and functionality. The mini jaw crusher is described as being on tracks, making it easy to move around, and having a diesel engine and a conveyor belt to facilitate the crushing process.

💡tracks

Tracks refer to the continuous, flexible bands that encircle the wheels of certain heavy machinery, such as tractors or mini jaw crushers. They are designed to provide better traction and stability on uneven terrain and to distribute the weight of the machine more evenly, reducing ground pressure. In the script, the mini jaw crusher rolls on tracks, which is a feature that makes it easy to move around the work site.

💡diesel engine

A diesel engine is an internal combustion engine that uses diesel fuel to generate mechanical power. It is commonly used in heavy machinery due to its reliability and ability to produce significant torque at low speeds. In the context of the video, the mini jaw crusher is powered by a diesel engine, which is crucial for its operation as it provides the necessary force to crush the rocks.

💡conveyor

A conveyor is a system used to transport materials from one place to another in a continuous and automated manner. It typically consists of a moving belt that carries the material along a specified path. In the video, the mini jaw crusher is equipped with a conveyor belt that pulls the crushed material away from the crusher, which is an important feature for efficient operation and material handling.

💡hydraulic pump

A hydraulic pump is a mechanical device that generates fluid pressure by converting mechanical energy into hydraulic energy. It is a key component in hydraulic systems, which are used to transmit power in various applications, including heavy machinery like the mini jaw crusher. In the script, the hydraulic pump is mentioned as part of the crusher's system, suggesting it plays a role in the operation of the machinery, possibly in actuating the jaws or other moving parts.

💡clutch

A clutch is a device that engages and disengages power transmission, especially from driving shafts to driven shafts. In vehicles and machinery, clutches allow the driver or operator to control the transfer of power smoothly. In the video, the switch that engages the clutch is mentioned, which turns on the crusher, indicating that the clutch is used to control the operation of the mini jaw crusher.

💡oil air filter

An oil air filter is a component that cleans the air entering an engine by removing dust and other contaminants, which can be harmful to the engine's performance and longevity. It is an essential part of maintaining the health of any engine, including those in heavy machinery. The script mentions an oil air filter, which is noted for being clean, suggesting that the mini jaw crusher has been well-maintained.

💡shim

To shim means to insert a thin piece of material, such as metal or plastic, to adjust the alignment, spacing, or fit between parts. In the context of the video, the presenter mentions that the jaws of the mini jaw crusher can be shimmed to adjust the size of the material that can be processed. This is an important feature for versatility, allowing the crusher to handle slightly larger rocks if needed.

💡material

In the context of the video, 'material' refers to the rocks and minerals that the mini jaw crusher is processing. The type of material being crushed can affect the efficiency and performance of the crusher. The script mentions 'softer material' and 'shale,' which break up more easily, and the resulting crushed material is described as being suitable for applications like driveways.

💡screening

Screening is the process of separating materials based on size by passing them through a screen or sieve. In the mining and construction industries, screening is used to classify crushed materials into different sizes. The script mentions screening the crushed material to obtain 'three quarter stone,' which is a specific size of crushed rock used in various construction applications.

💡excavator

An excavator is a piece of heavy construction equipment consisting of a boom, stick, bucket, and cab on a rotating platform known as the 'house.' It is used for digging, grading, or moving large amounts of material, such as dirt or rocks. In the video, the presenter mentions loading the mini jaw crusher with a smaller excavator, indicating that excavators are used to feed material into the crusher.
