The vertical shaft impact crusher ,also called sand making machine
and rubble shaping machine ,is a kind of crusher impact by the
materials themselves.It is of high energy but low consumption and
of international advanced level developed by introducing foreign
outstanding technology of the same type of products.
Sand making machine main features:
(1) PCL Sand Cruhser is with simple structure and low cost.
(2) It has high efficiency while saving energy and high reduction
(3) The equipment has the function of fine and coarse grinding.
(4) The non-crushed materials can easily pass through the
equipment, which is seldom influenced by water in the materials.
The moisture content is allowed to reach 8%.
(5) It is capable of crushing medium and extra hard materials (such
as corundum and sintered bauxite, etc.).
(6) The product is in the shape of a cube with little iron
(7) Self-supporting of materials in impeller and vortex crushing
cavity greatly reduces cost of worn parts and amount of maintenance
(8) It is convenient to operate, maintain and install the
(9) The noise intensity is lower than 75 decibels (dB level).
(10) The equipment is characterized by little weight, various
installation methods and movable installation, etc.
Working principle of sand making machine:
The granularity of stone enters sand making machine though belt
conveyor. Stones will be crushed by hitting other stones. Material
falls down to impellor cavity. Under the high speed centrifugal
force, it hits material that coming downwards. After hitting each
other, they force a vortex between impellor and shell, and hit each
other several times, finally the smaller stone comes out from the
bottom, and goes to vibrating screen. The qualified materials will
be transported to sand washing machine, however unqualified
materials will return to sand making machine to be crushed again.
Output sizes can be made according to customer’s requirement. If
input size is larger than the designed size, other crushing
equipment will be necessary.
Vertical shaft impact crusher
