Xinhai spring insurance crusher hard ore ideal equipment

Spring-safe cone crusher is a type of cone crusher. The cone crusher is mostly used in the fine-breaking field, and it has a unique advantage in the stage crushing, especially in the second-stage crushing work. At present, China's most widely used cone crusher mainly has two types, mainly spring cone crusher and hydraulic cone crusher. Xinhai Machinery's spring-safe cone crusher has made certain technological changes to high-hard ore, making the cone crusher more suitable for handling high-hardness ores of iron, quartz, and silicon.

This type of spring-loaded cone crusher is a typical equipment that our company's main players use to crush or crush the hard ore. Its structure is roughly the same as the gyratory crusher, but its working mechanism, adjustment device, dust-proof device and safety device are different.

First of all, as far as the working mechanism is concerned, the improvement of Xinhai Machinery is mainly the nesting of crush cones and fixing cones with manganese steel liners. This allows the zinc alloy between the lining and the vertebral body to ensure the close integration of the various components. The crushing cone is press-fitted onto the main shaft and its lower surface has a spherical shape and is supported by a spherical bearing. The lower end of the main shaft is inserted into the tapered bore of the eccentric bushing. A bush made of bronze is provided in the tapered hole of the eccentric bushing. When the motor drives the eccentric bushing to rotate through the bevel gear, the main shaft and the crushing cone supported by the spherical bearing perform a pendulum movement so as to achieve the purpose of crushing the ore.

Secondly, in terms of its adjustment device, Xinhai Machinery effectively combined it with a fixed cone to make it a part of a fixed cone. It consists of adjusting ring, supporting ring, locking nut, pushing cylinder, locking cylinder and piston. When it is necessary to adjust the discharge port, the locking hydraulic cylinder is first unloaded to loosen the rectangular thread, then the hydraulic system is operated, the hydraulic cylinder is started to drive, and the adjustment ring is driven to rotate. The fixed cone rises due to the transmission effect of the sawtooth thread. Or drop to achieve the purpose of adjusting the discharge port.

Again, the crusher can use an inert gas accumulator overload protection device. Normally, the accumulator pressure is slightly higher than the hydraulic pressure in the hydraulic cylinder, so the oil cannot enter the accumulator. Once overloaded, the force of the crushing cone will polarize significantly and the hydraulic pressure of the hydraulic cylinder will rise sharply. When the oil pressure rises too high After the nominal pressure of the energy device, a leakage phenomenon occurs and the oil body presses out, so that the crushing cone descends, the discharge port increases, and the non-broken object excludes the body. At this time, the oil pressure will gradually recover. When the critical point is reached, the vertebral body will retract again, thus changing the cone position so that it can continue to work normally.

The high-performance spring-loaded cone crusher is technically capable of crushing ultra-high hardness materials and is an ideal crushing device with high crushing ratio, high pressure output and high crushing capacity. In combination with Xinhai mechanical static cone improvement, the crushing efficiency of the equipment can be maximized.
