Similarly, various parameters like number of crushing stages, type of stone to be crushed, eccentric speed, feed rate or throw affect its performance. Similarly, when it comes to efficiency, the crusher relies on delivering crushing energy into the material contained within the crushing chamber or cavity.
The crusher uses a single hammer rotor with peripheral speed of about 40 meters per second. No inlet grating is necessary as the crusher is fitted with rollers to absorb the shock of the large rocks in the feed. The crusher is suited to handle materials containing a certain proportion of the sticky material.
It has been reported that the hammer circumferential velocity changes at an optimum range of 60-80 ms-1 in terms of grinding efficiency and that the specific energy consumption increases significantly at hammer peripheral speeds above these values, due to the increase in ventilation resistance in the crusher unit (Dmitrewski, 1982).

An energy efficiency study was performed by Legendre and Zevenhoven (2014). In their study, energy was estimated with the Bond work index, and an on-line optimization algorithm was used to increase the efficiency of a laboratory crusher.
The minimum size of the particles that undergo breakage is assumed to be a function of the impact energy and the feed rate. The model predictions are compared with experimental data obtained for limestone treated in a pilot-plant hammer crusher. The dependence of the product size distribution on the rotor velocity is investigated.

The design and technology of the stone crusher machine allow for high energy efficiency and environmental performance. Some advanced stone crushers use energy-efficient motors and efficient hydraulic systems to reduce energy consumption and emissions.
Hammer crusher is mainly used to crush material by impact. The crushing process is roughly like this. The material enters the crusher and is broken by the impact of a high-speed rotary hammer. The broken material obtains kinetic energy from the hammerhead, and thus rushes towards the baffles and screen bars at high speeds.
Furthermore, the growing focus on sustainable mining practices and environmental regulations is expected to drive the demand for hammer crushers that are energy-efficient and have lower emissions.
