How to Reduce the Energy Consumption of Crushers?

Reducing the energy consumption of crushers is an important direction for the mining, building materials and other industries to achieve green production. Systematic measures need to be taken from multiple dimensions such as equipment selection, process optimization, and operation management. First of all, the type of crusher should be reasonably selected according to the hardness, particle size and other characteristics of the material. For example, the energy efficiency of the cone crusher based on the lamination crushing principle is about 30% higher than that of the traditional jaw crusher. Secondly, it is necessary to strengthen the pretreatment of raw materials, remove qualified particle materials through pre-screening, avoid repeated crushing of equipment, and control the feed particle size within a reasonable range to reduce the load on the equipment.

In terms of operation management, regular maintenance of key equipment components such as bearings, wear plates and blow bars,, and keeping the lubrication system running efficiently can reduce the additional energy consumption caused by friction loss. Optimize the crushing process, adopt the principle of "more crushing and less grinding", reduce the product particle size as much as possible in the coarse crushing and medium crushing stages, and reduce energy consumption in subsequent links. Introduce an automated control system to monitor equipment current, vibration and other parameters in real time, dynamically adjust the feeding speed and crushing chamber pressure, and ensure that the equipment is always in an efficient operation range.

In addition, the promotion of variable frequency speed regulation technology can reduce the motor power output under low load conditions, and the energy saving effect can reach 15%-20%. Enterprises can also establish single machine energy consumption assessment indicators through energy management systems, and form a long-term mechanism by combining equipment upgrades and process modifications. The comprehensive use of the above measures can reduce the energy consumption of the crushing system by 20%-30% without increasing production costs, achieving both economic and environmental benefits.
