This customer’s working site is on an island, which is lack of electricity, that is why the customer choosed the diesel engine model. He is doing some small projects, such as building houses, hotels, churches, there is no big concrete batching plant on this island, so this small mobile diesel engine concrete mixer is the best choice for him, each set can produce 20-22m3 concrete per hour, totally he purchased 2 sets, so the capacity of per hour is 40-45m3/hour.
