300MPa Stone Crusher Machine

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.
