Limestone Crushing Plant Production 108000 Tonnes/Month

Limestone formation can occur mechanically, chemically and organically. Limestone dissolves easily in water and the color of this stone is generally grayish white. Processing of minerals (mineral processing technology) is the process of separating valuable minerals from their impurities by utilizing the differences in the physical properties of the minerals without changing the chemical and physical identity of the product. To reduce the mined material, which is generally still lump-sized, a crusher is used. In principle, rock crushing aims to reduce the material in order to obtain a certain grain size, through a crusher and sieving device. In crushing the size of the rock is generally carried out through 3 stages, namely: primary crushing, secondary crushing and fine crushing.

Limestone Crushing Process

The processing unit greatly determines the economic value of industrial mining due to market needs that require different cement, so that the rock resulting from splitting/blasting must go through processing or reduction according to a predetermined size, namely 2.5 – 5 cm so that it can enter the process. production.

This research was conducted to optimize limestone production within a maximum of 30 days. Based on research and calculations in the field, it is known that the work efficiency of the limestone crushing plant 09 unit is low, 62.87% with a total production only 73.846 tons/month. After many refinement efforts, work efficiency of the limestone crushing plant 09 unit increased 17.31% to 80, 19%, to increase the production target, refinement efforts were made to increase effective working hours by minimizing time constraints, and working time management accordingly production targets were achieved, therefore target production increased from 2,275 tons / shift to 4,173 tons / shift and the final production of crushing plant 09 increased to 125,190 tons / month.
