Description

What is Box Crusher?

Box crusher is our company absorbs advanced technology at home and abroad, comprehensive jaw crusher, hammer crusher, impact crusher, snail crusher and other crusher advantages of the integration of stone breaking machinery. Large stones directly into the crusher, automatic feeding, directly the side length of 450-1200 mm material broken into powder to 80 mm particle size of ore, and no blocking machine, can also be used as a secondary crusher, mainly used in mining, cement, building materials, chemical industry and other industries.

Size and Capacity of Heavy Hammer Crusher

The box crusher has a full discharge shape and a capacity of 70-400 tons per hour, and the finished products can be used in buildings, roads, airports and other construction.

Box Crushers

Features

The feed particle size is large, the crushing ratio is large, and the discharge is uniform.

The finished product rate is high, and the granular product accounts for about 85%, which fully meets the use requirements.

The hammer shaft is adjustable and long life hammer head.

The hammer head, grate plate and impact plate are made of high manganese steel wear-resistant material, which has a longer service life.

The chassis can be flipped over for easier maintenance

The box crusher has a simple structure, is easy to unpack, and can quickly handle blockages and replace hammers.

Anti-splash design of feed inlet

The feed port is equipped with an iron chain barrier to prevent material from splashing during the crushing process.

Working Principle

Box Crushers
The stones fall directly from the top of the machine onto the high-speed rotating turntable. Under the action of high-speed centrifugal force, they produce high-speed impact and high-density crushing. After hitting each other, the stones will form eddy currents between the turntable and the casing, causing multiple mutual impacts, friction, and crushing until they are crushed into the required parts.

Application & Case

Box crusher is suitable for primary and secondary crushing of various materials with compressive strength below medium and upper hardness. It is especially suitable for crushing materials used in mining, building materials, chemical and metallurgical industries. The compressive strength of the crushed material is not more than 100 MPa, and the humidity is not more than 15%.

FAQ

The service life of the whole machine is 8 to 12 years (under regular maintenance), but the hammer head, screen plate and other wearing parts need to be replaced every 3 to 6 months.
Main wearing parts: hammer head, screen plate, liner, bearing. Replacement cycle: hammer head: 300~1000 hours (related to material hardness); Screen plate: 500~1200 hours (susceptible to material adhesion); Bearing: regular lubrication can be extended to 1~2 years.
Medium and low hardness (Mohs hardness ≤ 200MPa), brittle materials, such as limestone, coal gangue, shale, gypsum, construction waste, etc.
Clean the crushing chamber and screen plate; check the tightness of the bolts to prevent the hammer head from falling off; correct the dynamic balance of the rotor to reduce vibration.
