MMD

MMD's core product is the Twin Shaft Mineral Sizer – a high capacity, compact crusher capable of accurately sizing any combination of wet, sticky, hard or dry material. The unique breaking action subjects material to stress, bending, tension and sheer forces as opposed to compression forces used in traditional crushers.

Short-term planning of open pit mines with Semi-Mobile IPCC: a shovel

ABSTRACT In-pit crushing and conveying (IPCC) is considered a suitable alternative to truck haulage in open pit mines because it offers a lower operating cost than a truck-shovel system. It also reduces truck haulage distance and truck requirements. One of the IPCC variations is the semi-mobile system, which is relocated every two to five years. The short-term plan needs to …
