Reduced mechanical stress leading to increased lifetime

You need your crushers to be as efficient and economical as possible for the best quality cement and production output. With the precise speed and torque provided by our low and medium voltage AC drives, the mechanical stress on the crusher and the motor is vastly reduced from smooth starting and stable speed control. This helps you reduce maintenance and increases equipment lifetime and uptime. And our products are backed by a global service and support network.

The right speed. Correct torque. Efficiency. Everything counts for cost-efficient and dependable crushing.

Highlights

Soft starting

Elimination of voltage fluctuations in supply network

Minimized wear and tear of mechanics, means improved reliability and prolonged crusher lifetime

Reduced operational and maintenance costs compared to slip-ring motor solutions

Dynamic torque regulation

Elimination of undesirable dynamic effects

Lower reactive power consumption and reduced need for compensation equipment compared to other control methods

Substantial energy savings

Reversing of motor in case of blocked crusher

This article was published on the original KEWO site in 2015 as general guidance on drive selection for this load type. The technical points apply to any low or medium voltage AC drive, including the KEWO AD and SD3000 series.
