Comprehensive Industry Stone Crushers
Stone Crushing Industry is an important industrial sector in the country engaged
in producing crushed stone of various sizes depending upon the requirement
which acts as raw material for various construction activities such as construction
of Roads, Highways, Bridges, Buildings, Canals etc.
Liming Heavy Industry(Shanghai) has exported many stone crushers to India, such as Mobile Jaw Crusher, Mobile Cone Crusher, Mobile VSI Crusher, European Type Jaw Crusher, VSI5X Vertical Shaft Impact Crusher., etc. Below is one mobile crushing plant running in India.
If you are interested in our stone crushing plant, please be free to send me an email (limingjqs@gmail.com) or chat with our sales manager assistant online to get price, manual and other running pictures.
It is estimated that there are over 12,000 stone crusher units in India. The number is expected to grow further keeping in view the future plans for development of infrastructure of roads, canals and buildings that are required for overall development of the country. In India, the Stone Crushing Industry sector is estimated to have an annual turnover of Rs. 5000 crore (equivalent to over US$ 1 billion) and is therefore an
economically important sector. The sector is estimated to be providing direct
employment to over 500,000 people engaged in various activities such as mining,
crushing plant, transportation of mined stones and crushed products etc. Most of
these personnel are from rural and economically backward areas where
employment opportunities are limited and therefore it carries greater significance
in terms of social importance in rural areas. It is a source of earning for
uneducated poor unskilled rural people.
The stone crusher is one such industry that exists in the vicinity of almost all
major cities/towns throughout the country in all the states because the
construction activities go on throughout the country. As transportation of stone
over long distances adds to cost of the crushed stone products, the crushers
need to be necessarily located nearer to the demand centers such as Cities,
Bridges, Canals etc. Stone Crushers also need electricity supply and large number
of man power for its operation. It also needs access roads for the movement of
mined stone as well as crushed stone products. It is for these reason that most
Stone Crushers are located along the periphery of Cities or in the vicinity of major
construction projects. In most cases the Stone Crushers come up in clusters of
number of units ranging from five to fifty in one cluster. The crushers are located
nearer to the source of raw material such as Stone mines, River Beds etc.
These stone crushers though socio-economically an important sector, gives rise
to substantial quantity of fine fugitive dust emissions which create health hazards
to the workers as well as surrounding population by way of causing respiratory
diseases. The dust also adversely affects visibility, reduces growth of vegetation
and hampers aesthetics of the area. In order to prevent/control these emissions,
CPCB has already evolved Emission Standards and guidelines in 1989, which has
been notified under Environment (Protection) Act, 1986 by Ministry of
Environment & Forests vide Notification No. G.S.R. 742(E) dated 30th August
1990 & S.O. 8(E) dated December 31, 1990 based on techno-economic feasibility
to achieve the standards. But over the years, as the need for more effective
control and enforcement has been felt and to provide more specific guidelines to the stone crushers to enable them control emissions satisfactorily, CPCB has signed a Memorandum of Undertaking (MoU) with National Productivity Council (NPC) and commissioned the study with the work of reviewing the existing standards, guidelines and sitiing criteria and to evolve a Comprehensive Industry Document (COINDS) for Stone Crushers. This report is an outcome of the indepth studies carried out by NPC jointly with CPCB on a representatives cross section of Stone Crushers throughout the country and a series of meeting held with State Pollution Control Boards, Stone Crushers Associations / Stone Crushers unit representatives etc..
