Square box crusher

Detailed introduction of box crusher:

Basic overview

Definition: Box crusher is a new generation of crushing machinery products manufactured and produced after optimizing design by absorbing advanced technologies at home and abroad, integrating the principles of ordinary hammer crusher, impact crusher, vertical shaft hammer crusher, etc.1.
Structure: The frame part is a three-part structure. Open the rear casing of the crusher to replace the hammer, crushing plate, liner and other maintenance operations. The parts are highly interchangeable and there are few types of wearing parts1.

Working principle

The stone falls directly from the upper part of the machine into the high-speed rotating turntable. Under the action of high-speed centrifugal force, high-speed impact and high-density crushing are generated. After the stones hit each other, eddy current motion will be formed between the turntable and the casing, causing multiple mutual impacts, friction, and crushing until they are crushed into the required particle size1.
Driven by the motor, the rotor disk drives the hammer to make high-speed circular motion. The large pieces of material are piled on the special middle bar in the machine. After crushing, the material with a particle size larger than the requirement is hit along the tangent direction of the hammer head with the new material to the impact plate for further crushing, so that the coarse and medium crushing are completed in one step. Finally, the material that meets the requirements is discharged after being integrated through the grate plate.
Performance characteristics 1

Feed and crushing ratio: The feed particle size is large, up to 1200mm, and the crushing ratio is large. The material of 500-1200mm can be directly crushed to less than 25mm at one time.
Discharge quality: The discharge is uniform, the yield is high, the granular products account for about 85%, the needle-like products are few, the products are cubic, the stacking density is large, which can effectively reduce the phenomenon of over-crushing, and the finished product particle shape is good, which fully meets the use requirements.
Equipment life: The hammer head, grate plate and impact plate are made of highly wear-resistant materials. The hammer head has a long life. Each pair of hammer heads can crush 30,000-40,000 tons of stone. The equipment is durable as a whole.
Overhaul and maintenance: The chassis can be flipped, the hammer shaft installation is adjustable, the square handle bolts are impact-resistant and wear-resistant, and there are fewer wearing parts, the spare parts are easy to replace, the maintenance cost is reduced accordingly, and the overhaul is more convenient.
Production capacity: high output, stable performance, coarse and medium crushing in one step, simplified process flow, can effectively improve production efficiency.
Power consumption: small matching power, low energy consumption, adopting the driving mode of motor + mechanical coupling + V-belt + crusher, can effectively improve the motor starting performance, make the motor run smoothly, and reduce operating costs.
Product particle size control: The grid size is adjustable, the product particle size is controllable, and the discharge particle size can be adjusted conveniently and flexibly with a wide adjustment range.
Material adaptability: It can effectively handle materials with high moisture content and prevent the crusher from clogging. It is suitable for both soft materials and materials with very high hardness, and for the primary and secondary crushing of various materials with compressive strength below medium and upper hardness.
Application field 1

Mining industry: It is used for coarse and medium crushing of ores, such as iron ore, copper ore, limestone, marble, quartzite, river pebbles, granite, basalt and other ores.
Building materials industry: It can crush raw materials such as limestone and gypsum to provide qualified raw materials for cement production. It is also used in the production of building sand and gravel to provide high-quality building sand and gravel.
Chemical industry: It can crush chemical raw materials, such as coal gangue, salt and other materials, to provide raw materials of suitable particle size for chemical production.
Metallurgical industry: It can process metallurgical slag, steel slag, etc. to realize resource recycling. It can also be used for the pretreatment of metal ores to provide qualified raw materials for subsequent mineral processing and smelting processes.
Highway construction: produce the crushed stone materials needed for road construction and provide high-quality stone for highway pavement base and subbase.
