Stone Crusher and Granulator
Crushers are used to reduce the
large rock or boulders into smaller and uniform sizes useful for concrete mix. The
various stages involved in the production of crushed aggregates are drilling,
blasting, loading, transporting, crushing, screening, handling and storing.
Crushers are classified as
follows:
·
Pressure Crushers : Jaws crushers and Gyratory
Crushers.
·
Impact Crushers : Hammer Mills and DTS
Integrators.
·
Poll Crushers : Grinding Type Machines.
Compressors and Pneumatic Tools
Compressed air is widely used
in construction operation for drilling rocks, loosening earth, operating air
motors, hand tools, pile drivers, pumps, mucking equipment, cleaning, etc. The
energy supplied by compressed air is the most suitable method of operating
equipment and tools. When air is compressed, it gets the required energy from
the compressor. This energy is later on transmitted through a pipe or hose to
the operating equipment. This portion of transmitted energy is converted into
mechanical work.
Air compressor can be defined
as a machine used to increase the pressure by reducing its volume.
Following are the various types
of compression:
·
Reciprocating compressor
·
Single-acting compressor
·
Double acting compressor
·
Centrifugal compressor
·
Rotary compressor
Stationary compressor
Stationary compressors are
generally installed where compressed air is required for a longer period. They may
be driven by steam, electric motors or I.C. engines, stationary compressor
consists of prime mover, suction line, air filter, intercooler, safety valves,
after coolers, receiver and distribution system.
Portable compressor
It is used when the equipment
is required to be moved frequently to meet the demands.
