WHAT IS THE DIFFERENCE BETWEEN AN SLM AND A MANUAL DRUM MIXER ?

The advantages of the SLM over manual concrete mixers are endless, and very often justify the difference in investment (even in the poorest countries). As well as reduced labour, greater daily productivity, and complete independence from any other loading and transportation devices, SLMs enable components to be dosed and mixed to produce high quality concrete. In emerging and developing countries, the SLM is now considered the first level of mechanisation/monitoring in concrete production.
