These have a reduction ratio of around 10:1 to 25:1 and are hence used for the extracted materials, sand, gravels etc. [6]. Vertical shaft impact crusher These crushers use a high speed rotor that has its axis along the vertical axis. The vertical-shaft impact crusher can be considered a stone pump that can operate like a centrifugal pump.
Pioneers of Impact Crushing. In the early 1960's, after observing shortcomings in existing crusher technology, CEMCO (acquired by Superior in 2023) embarked on a journey to design a better crusher for chips and sand production. The result was the creation of the modern vertical shaft impact (VSI) crusher, a pioneering design that has stood ...

The shaft has high fatigue resistance because of its quality surface finish and the absence of screw threads and sharp radii that can cause stress concentrations. …
An HSI crusher consists of a rotor assembly that contains a horizontal shaft, a number of blow bars or hammers, and a breaker plate fitted onto the body. The rotor assembly rotates at high speed, causing the hammers or blow bars to strike the material, material will collide with breaker plate and material break it into smaller pieces.
The main components of a cone crusher include the main shaft, mantle, concaves, cone, eccentric bushing, drive, crown gear, frame, and tramp release mechanism (mechanically or hydraulically actuated).
Jaw Crusher Parts. Although the jaws do the work, the real heart of the jaw crusher and its components are the toggle plates, the pitman, and the ply wheel. These are the parts and components that …
Jaw Crusher Parts. Although the jaws do the work, the real heart of the jaw crusher and its components are the toggle plates, the pitman, and the ply wheel. These are the parts and components that generate the crushing action and provide the energy needed to break the ore. Let's follow the chain of events within a crushing cycle to see how ...
IMPACT ENERGY CALCULATION PER UNIT MASS FOR A HORIZONTAL SHAFT CRUSHER. The Basic Assumptions made here: 1. Rotor mass is much greater than mass of single particles in the feed 2. Before impact, linear velocity of the crushing bar is much more important than the particle velocity. Hence KE of particles is negligible.
Horizontal Shaft Impact Crushers. Horizontal Shaft Impact Crushers, such as the New Holland, Andreas and MaxCap (which is a hybrid of the two) styles, are typically used for the primary size reduction of soft to medium hard materials.

Size Reduction) A crusher is a machine designed to reduce the size of large rocks to smaller rocks, gravel, sand, or rock dust; this is essential for efficient transport of the product via conveyors etc. Crushing is the first of many stages that lead to separation of the mineral(s) from the waste (gangue) material.Waste material can be discarded or …
The cone crusher working principle involves the eccentric motion of the main shaft. This motion is created by the rotation of the main shaft, which is supported by a bearing located at the top of the machine. As the main shaft rotates, it causes the mantle to move back and forth against the concave, crushing the rocks and ores between them.
