Box-type breaker

Product description

Box crusher is also called hammer crusher and square box crusher. In terms of the mechanical principle of crushing, after optimized design, the latest generation of crushing machinery products have been manufactured and produced, which has changed the method of controlling the size of discharged particles with grate bars, reduced the wear of the hammer head in the crushing cavity, and increased the life of the hammer head. It is increased by 4-6 times, and each set of hammers can crush 30,000 to 40,000 tons of stone, which has achieved a major breakthrough in crushing technology and truly achieved the effect of getting twice the result with half the effort.

Equipment structure

The frame part of the box crusher is a three-part structure, and the repair and maintenance operations such as the replacement of the blow hammer, the crushing plate and the lining plate can be carried out only by opening the rear casing of the crusher. The parts of the box crusher are highly interchangeable, and there are few types of wearing parts, which is convenient for the procurement and management of spare parts. The hydraulic opening device is used to open and close the casing, which can effectively reduce the maintenance labor intensity, improve the maintenance work efficiency, and shorten the maintenance work time. The monitoring system of the box crusher can monitor the operation status of the crusher at any time, and the monitoring signal can be interlocked with the main control system to ensure the safe and reliable operation of the machine. The drive system of the box crusher adopts the method of motor + mechanical coupling + V-belt + crusher, which can effectively improve the starting performance of the motor and enable the motor to start and run smoothly. The belt drive mode can play a double overload protection function, and the motor power required by the drive system is low, which greatly reduces the operating cost. This drive scheme is an economical, practical, high-performance, safe and reliable drive scheme.

Performance characteristics

• 1. The feeding granularity is large, the crushing ratio is large, and the discharging is uniform.
• 2. The finished product rate is high, and the granular products account for about 85%, which fully meets the requirements of use.
• 3. The installation of the hammer shaft of the box crusher is adjustable, and the hammer head has a long service life.
• 4. The grid size is adjustable, the product particle size is controllable, and the particle shape is good.
• 5. The box of the box crusher can be turned over, which is more convenient for maintenance.
• 6. Square shank bolts, shock and wear resistant.
• 7. High output and stable performance.
• 8. Coarse and medium crushing can be done in one step, and the technological process is simplified.
• 9. Using high wear-resistant material hammer, grate plate and impact plate, the service life is longer.
• 10. The supporting power is small, the energy consumption is low, the maintenance is simple, and the wearing parts are few.

Working principle

The stone falls straight 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 occur. Hit each other, rub, and crush each other for many times until crushed into the required particle size.
