Types of DIY Rock Crushers
DIY rock crushers come in various designs, each with its unique working principle, advantages, and limitations. These designs are categorized based on the mechanism used to crush the rocks.
Jaw Crushers
Jaw crushers are one of the most common types of rock crushers. They consist of two jaws, one fixed and one movable, that move towards each other to crush the rocks.
- The fixed jaw is usually stationary, while the movable jaw is driven by a motor or engine. The movable jaw swings back and forth, crushing the rocks between the two jaws.
- The gap between the jaws, called the “crusher setting,” can be adjusted to control the size of the crushed rock. A smaller gap produces finer particles, while a larger gap produces coarser particles.
- Jaw crushers are typically used for primary crushing, meaning they are the first stage in the crushing process. They are robust and can handle large rocks, making them suitable for applications like mining and construction.
Cone Crushers
Cone crushers are similar to jaw crushers but use a conical crushing surface instead of two jaws. The cone rotates eccentrically, crushing the rocks between the cone and the fixed crushing mantle.
- The gap between the cone and the mantle is adjustable, allowing for control over the size of the crushed rock. The crushing chamber is also designed to ensure that the rocks are crushed evenly.
- Cone crushers are typically used for secondary crushing, following primary crushing with a jaw crusher. They are more efficient than jaw crushers at producing finer particles and are often used in applications like aggregate production and recycling.
- Cone crushers are generally more complex and expensive than jaw crushers but offer higher capacity and efficiency.
Impact Crushers
Impact crushers utilize a high-speed impact mechanism to break down the rocks. They consist of a rotor with hammers or bars that strike the rocks, causing them to break apart.
- The rotor rotates at high speed, and the rocks are fed into the crushing chamber, where they are struck by the hammers or bars. The impact force breaks the rocks into smaller pieces.
- Impact crushers are well-suited for producing cubical-shaped crushed rock, which is desirable for applications like concrete production and asphalt paving.
- They are typically used for tertiary crushing, following primary and secondary crushing, and are often employed in applications requiring a high degree of size reduction and cubical shape.
Materials and Tools for DIY Rock Crushers
Building a DIY rock crusher requires a selection of materials and tools. The choice of materials depends on the type of crusher being built and the size and hardness of the rocks to be crushed. Similarly, the tools needed will vary depending on the construction process and the complexity of the design.
