    Product introduction

    Box crusher is also called square box crusher, which is called box crusher for short, It is a new generation of crushing machinery products produced by absorbing advanced crushing technology at home and abroad, integrating common heavy hammer crusher, impact crusher, hammer crusher and various hammers (plate hammers) for stone crushing. After optimization design, the new generation of crushing machinery products are manufactured, which changes the way of controlling the size of discharging particles with grate bars, and reduces the grinding of hammer head in the crushing chamber Each hammer can crush 30000-40000 tons of stone, realizing a major breakthrough in crushing technology and achieving the effect of twice the result with half the effort.

    Highlight advantages

    Silkworm bite crushing technology, feed more

    The machine is designed to be smaller and larger for material feeding.

    It has the advantages of simple structure, easy maintenance and lower cost

    The utility model has the advantages of simple structure, smaller power, convenient maintenance and lower comprehensive use cost.

    Grate control, no return material, higher yield

    The lower part is designed with grate plate, and the particle size of finished product is controllable. The yield of finished product is higher under 3cm, and there is almost no return material.

    Large hammer head, high chromium alloy material, more durable

    It is made of high chromium alloy and long service life.

    working principle

    ??? The mineral material falls into the box crusher body from the upper part of the machine. The material with the particle size larger than the bar is blocked, and the material smaller than the bar vertically falls into the high-speed rotating crushing chamber. Under the action of the hammer head, it impacts the large material above the bar with high speed, realizing the "silkworm bite" crushing. Moreover, some crushed stones will enter the lining plate through the holes of the lining plate to form the material lining together with the lining plate, The materials in the chamber are smashed repeatedly, rubbed and collided with each other to realize high-density crushing until the particle size is smaller than the diameter of the bottom grate plate, and the required particle size of the finished product is discharged.

    The box crusher is widely used in the primary and secondary crushing of various materials with compressive strength below medium and high hardness, especially for mining, building materials, chemical industry, metallurgy and other industries. The compressive strength of materials is not more than 100 MPa and the humidity is not more than 15%.
