Spring cone crusher

Product Description

This spring cone crusher is typically designed to process a variety of mid-hard and above mid-hard ores and rocks in different fields, like metallurgy, construction, road building, chemistry, etc. 
When compared with jaw crusher, the spring cone crusher has more advantages, such as stable structure, high production efficiency, convenient adjustment, lower operational costs, and more. Its spring safety system is used as the overload protection system to allow foreign iron lumps to get through the crushing chamber without damage to the crusher. Both glycerin and water sealing modes are employed to separate the stone powder and lubrication oil, thus achieving stable and reliable operation. The shape of the crushing chamber is decided by the size of feeding material. The standard form is suitable for medium crushing, and the medium and short ones is appropriate for fine crushing.

 

Working Principles
Materials become squeezed and crushed between the movable and fixed cones. So the spring cone crusher is more advanced and efficient than the jaw crusher. Its movable cone is held by the spherical bearing, and the fixed one by a hanging erect shaft that is set in the eccentric sleeve of the stop and push bearing.

Both the movable cone and erect shaft are driven by the eccentric shaft sleeve. And the eccentric shaft sleeve is driven by horizontal shaft and fabricated gear, and the wheel of conveyor belt is directly driven by motor via the v-belts. The lower part of vertical shaft is fitted in the eccentric sleeve. When the eccentric sleeve rotates, a conical surface forms. Once the movable cone moves near the fixed one, rocks and ores are broken, and when the movable cone leaves, crushed material will be discharged. Besides, the fixed cone can go up and down in order to adjust the width of discharge hole.

Impact Hammer Crusher

Product Description

Our impact hammer crusher is typically designed to crush various ores whose granularity is no more than 500mm and compressive strength no less than 350 MPa, like granite, limestone, basalt, and more. And it can be widely used in a large variety of fields, such as water and electricity, expressway, railway, artificial dinas, construction, etc.

The shape of this kind of crusher is cubic, and its discharging particle size is adjustable. It features high crushing ratio, high efficiency, energy saving, easy maintenance, and so on.

The working principle of this machine is as follows: rotor rotates rapidly driven by the motor. When materials enter into the crusher, they will be broken by impacting the hammer and lining plates again and again until they are discharged out via the discharge hole.

Jaw crusher

Product Description

Luoyang Building Materials& architectural design research institute base on the foundation of imported technologies, absorbing others successful experience from domestic and abroad, through a series of experimental research work, we successfully complete the systemic development and research work of preheater and precalciner with independent intellectual property rights, finally we got the ability to provide a series of equipment of 600 ~ 8000 T/D cement clinker production. Our preheating& precalciner system has a series of unique technical characteristics, such as low resistance, high decomposed rate, high fuel adaptability, good anti clogging performance, high operational flexibility and reliable production.

 This machine is mainly used in metallurgy, mining, chemical, building material, highway, railway, water conservancy and other industries, for a variety of ores and bulk materials in large pieces and crushing. Maximum compressive strength of the material to be broken for 2000Kg / cm2. Be breaking strength of not more than 320Mpa materials.

 

Structural principle

When the jaw crusher work, activity on the fixed jaw jaw periodically reciprocating motion, sometimes close, sometimes leave. When approached, the material being squeezed between the two jaw, splitting, the impact was broken; when the left has been broken by the force of gravity and the material discharged from the discharge port.

In the huge stones broken into small stones in the process, the first crusher usually "master" crusher. The oldest and most robust crusher is jaw crusher. When the jaw crusher feed for the material from the top of the entrance into the crushing chamber containing the jaw teeth, jaw teeth to the top of the great power of the material to the wall, it will be broken into smaller stones. Support jaw tooth movement is an eccentric live, this eccentric shaft through the body frame. Eccentric motion is usually fixed at both ends of the shaft of the flywheel generated. Flywheel and eccentric support bearings are often used spherical roller bearings, bearings must withstand tremendous impact loads, abrasive and high temperature water.
