Box Type Hammer Stone Crusher Machine Crusher Work Used In Mining
Cement Buliding Materials Chemical Industry
Introduction:
Box crusher, Also known as heavy hammer crusher, square box
crusher, is the absorption of advanced technology at home and
abroad, comprehensive ordinary heavy hammer crusher, impact
crusher, vertical shaft heavy hammer crusher and various hammers
(plate hammer) for stone crushing mechanical principle, after
optimization design, the latest generation of crushing machinery
products are manufactured, which changes the grate bar to control
the discharge of large particles The small method can reduce the
wear of the hammer in the crushing cavity, and increase the service
life of the hammer head by 4-6 times. Each hammer can crush
30000-40000 tons of stone, realizing a major breakthrough in the
crushing technology and achieving the effect of twice the result
with half the effort.
The box crusher has the advantages of high weight of single hammer
head, high rotation speed of rotor and large moment of inertia of
hammer head, which fully reflects the advantages of large breaking
small and heavy crushing light, and has the unique ability of
cannibalizing super block stone.It is widely used to replace cone
crusher, roller mill and ball mill in the world. The structure is
novel, unique and stable. It has the function of shaping, and the
product is square and has high packing density.
In the production process, the stone can form a protective bottom
layer, and the fuselage is wear-free and durable. A small number of
easy to wear parts are made of super hard wear-resistant material,
small volume, light weight, easy to replace accessories. Driven by
the motor, the rotor disk of box crusher drives the hammer head to
make high-speed circular motion. When the materials enter the
crushing chamber, large pieces of materials are stacked on the
specially designed middle support bar in the machine. After
crushing, the materials with the particle size larger than the
requirements are hit to the impact plate along the tangent
direction of the hammer head and then crushed again, so that the
coarse and medium crushing can be in place in one step.Finally, the
qualified materials pass through the grate plate Discharge after
qualified.
Working pricile:
The stone falls directly into the high-speed rotating turntable
from the upper part of the machine. Under the action of high-speed
centrifugal force, high-speed impact and high-density crushing will
be produced. After hitting each other, the stones will form eddy
current movement between the rotary table and the shell, resulting
in multiple strikes, friction, powder crushing and even crushing to
the required particle size.
The frame part of the box crusher is a three-part structure. It is
only necessary to open the rear shell of the crusher to replace the
plate hammer, crushing plate and lining plate. The box crusher
parts have strong interchangeability and less vulnerable parts,
which is convenient for the purchase and management of spare parts.
The hydraulic opening device is used to open and close the casing,
which can effectively reduce the labor intensity of maintenance,
improve the maintenance efficiency and shorten the maintenance
working time.
The monitoring system of the box crusher can monitor the operation
of the crusher at any time. The monitoring signal can be
interlocked with the main control system to ensure the safe and
reliable operation of the machine. The driving system of box
crusher adopts the mode of motor + mechanical coupling + V-belt +
crusher, which can effectively improve the starting performance of
motor and make the motor start smoothly. The belt drive mode can
play a dual function of overload protection. The motor power
required by the drive system is low and the operation cost is
greatly reduced. This drive scheme is economical, practical, safe
and reliable.
Advantage:
1. Large feed size, large crushing ratio and uniform discharge.
2. The rate of finished products is high, and the granular products
account for about 85%, which fully meet the requirements of use.
3. The installation of hammer shaft of box crusher is adjustable,
and the service life of hammer head is long.
4. The grid size is adjustable, the product granularity is
controllable and the particle shape is good.
5. The case of box crusher can be turned over, which is more
convenient for maintenance.
6. Square shank bolt, impact resistance and wear resistance.
7. High yield and stable performance.
8. Coarse and medium crushing are in place in one step, and the
process flow is simplified.
9. The hammer head, grate plate and impact plate are made of high
wear-resistant materials, with longer service life.
10.Small power, low energy consumption, simple maintenance and less
wearing parts.
