JD series high efficiency vertical shaft impact crusher is commonly known as sand making machine and shaping machine

After the improved design of mine conditions, it is the fourth-generation high-performance sand making equipment with the most advanced level in the world.

[feeding particle size] : 30-50mm

[production capacity] : 60-520t /h

[application field] :

It is used in sand and stone yard, mixing station, dry mortar, quartz sand, construction waste crushing and other industries

Dam construction, concrete mixing station to provide quality sand aggregate.

[applicable materials] :

River pebble, quartz stone, limestone, cobblestone, coal gangue, basalt, granite, diabase and so on

[product advantages]

Large processing capacity and even particle size

With a maximum throughput of 520 tons per hour, the output is 30% higher and stable than that of conventional equipment at the same power level. The product is cubic with good grain shape.

Reasonable gradation, adjustable fineness modulus, especially suitable for artificial sand and stone shaping.

Wearing parts with low consumption and long service life

The best crushing chamber impact Angle design, less friction between materials and wear-resistant parts, directly reduce the cost of equipment; Equipped with Germany original thin oil lubrication station

, thoroughly solve bearing heating and other problems, make the spindle bearing maintain constant temperature, extend the maintenance cycle and service life.

Easy to operate and maintain

The equipment is light in weight, various in installation mode and convenient in operation and use. Once the specific purpose is clear, only minor adjustment is needed to give full play to it

Its excellent performance; Equipped with hydraulic cover opening device, so that the broken chamber of the internal parts of the overhaul and disassembly is convenient and quick, saving time and effort.

Advanced technology for energy conservation and environmental protection

Core parts and components are all selected from international famous brands (bearings adopt TIMKEN brand with high precision grade) to ensure the low failure rate of the system; Equipment working noise is low

, unique air self-circulation system, greatly reduce the exhaust air volume, reduce dust, conducive to environmental protection.

[working principle]

JD sand making machine applies advanced selective crushing and disintegrating principle to directly exert enough kinetic energy on materials and convert kinetic energy into overcoming object through impact

The crushing energy required by the material. Material basically along its natural texture surface, cleavage surface fracture, good shape, low consumption. This machine can achieve "stone to stone" and"

The conversion of two working principles.

Center feed: the material falls into the hopper and enters into the high-speed rotating wheel through the center feed hole, which is rapidly accelerated in the wheel and its acceleration can reach dozens of times

Gravity acceleration, and then high speed from the ejection wheel, the first part of the free fall and rebound with another part of the material impact, and then impact the material together

Lining (stone hit stone) or counterattack block (stone hit iron), by rebound slanting upward impact to the top of the vortex chamber, and change its motion direction, deflection down

Moving, and impinging with the material emitted from the impeller runner to form a continuous material screen. Thus, a piece of material is subjected to two or more times in the eddy current crushing chamber

Probability of impact, friction and grinding and crushing action. The crushed material is discharged from the lower discharge port.
