◊ Nowadays experts have found out that transferring expenses are one of the main parts in total cost. There are times that, transferring expenses exceed original cost. New technology, approach & transferring machineries help us to deduct the total cost, so that we can obtain huge sale. Mine industry has a great correlation with transferring. As a matter of fact not knowing the recent science in this field has made increasing in total cost & has caused inefficiency in the world market. Such a scientific point of view & modernization cause increasing in end products.

◊ From the old days the cavemen used to build shelters & devices using stone, after thousands years it plays main role in producing cement & construction. These days manpower has been replaced by machines & these approaches have made progress.

◊ The basic method is the same; it means the crashed stones from the nature are leaded to the primary crusher by trucks, until it’s converted to small ones it’s transferred again by belt conveyor to secondary crusher to be turned into considered sizes.

◊ The wastes after transferring into the plant are separated. Considering to the nature of mineral products about 20% to 40% the wastes are accumulated in the plant area. These materials which are harmful to the nature are cost-centre in returning back to the mine.

◊ Nowadays modern mines are equipped to mobile crusher. In fact the crusher are put at the mineral zone, In this way after explosion the mobile crusher comes to the stones then stones are loaded in Feed hopper using excavator, after separating the spoiled products & primary crash, products are transferred on belt conveyor to go the aggregation plant & secondary crusher, in order to main process. This method is called “mobile aggregation plant” including minimum harm to the nature, manpower, expense time & with high efficiency.

In order to clarify, let’s compare a traditional mine with a modern mine.

◊ Disadvantages of traditional aggregation are as following:

▪ Purchasing cost including dump track. (considering the capacity of the mine & plant)
▪ Fuel, reparation, maintenance, replacing, depreciation costs of machineries which transfer the stones to aggregation plant.
▪ The cost of manpower dealing with transferring stone, insurance transferring of the workers, events etc.
▪ The cost of machinery & manpower which are going to store the spoiled products.
▪ The cost of machinery & manpower which are going to carry the spoiled products back to the mine.
▪ Unexpected costs those are normal for every mine.

◊ As a matter of fact in order to increasing in production, more machinery & manpower are needed, these come with more expenses & this crowded system causes to decrease in efficiency.

◊ Advantages of mobile aggregation plant:

▪ Crossing out the high purchasing cost of machines & replacement of belt conveyor with lower cost.
▪ Decrease in fuel costs, manpower, reparation & maintenance in using belt conveyors instead of trucks.
▪ Crossing out the storing cost of spoiled products because of separating these materials next to the mine.
▪ Crossing out the primary fixed crusher from the plant.
▪ High rapidity because of increasing in capacity & profitability.
▪ Decrease in factors dealing with transferring, therefore achieving in a manageable systems.
▪ Utilizable in residential area without any harm to the nature.
▪ Quickly moveable of mobile crusher in workstation as primary crusher with, the lowest cost.

◊ Since investment in mine field is a long-term investment, with a primary investment we guarantee the long-term profitability through decrease in expenses.
Some functions of mobile crusher are listed below:

▪ Mines: considering that is moveable, this instrument can work in a few workstations with just one mobile crusher. Mobile crusher along with mobile screens are the best tools for establishing a aggregation plant, ability to move to other location is the most useful advantage of this machine.
▪ Road construction & rail road: in road construction & transferring of aggregated stone for surface, base & sub base the main point is the cost of construction. In fact more than 50% cost of construction including grave, sand & its combination & the transferring cost from the nearby mines along the direction with crusher machineries & mobile screen it is possible to achieve desire size of aggregated stone from cutting stones with lower expenses of transferring.
▪ Building: after destruction of buildings materials like bricks, cement blocks, asphalts & concretes are achieved as a spoiled article. Some of them like concrete are included cement & steel parts which are useless. Mobile crusher with any harm to nature is capable to separate steel parts with magnetic separators & crushers the concrete, bricks & asphalts even in residential areas. These materials are also used in building and road construction.

◊ The POWER CRUSHER Company is an Austrian company which is working on fixed & mobile crusher & screen filed and SAMIM DERAKHSHAN Company is sole agent of power crusher in Iran.
