·The symmetrical arrangement of the roll allows the crusher to be balanced with great precision This significantly reduces machine vibrations and loads on surrounding structures and makes the crusher ideal for use in both mobile and semi mobile crushing systems Technical specification Application data Application Primary crushing
·Rotational energy is fed into the jaw crusher eccentric shaft by means of grooved pulley which usuall y has multiple V belt grooves designed in such a way that they hav e approximately equal weight;
·The main components of the crusher are Frame jaw plate Eccentric shaft toggle toggle plate Fly wheel Pulley Belts tension spring and motor as shown in figure 1 In figure left frame is fixed while right one is movable Right frame consist an eccentric shaft arrangement connected with flywheel and pulley
·Through pulleys and a belt drive arrangement the speed can be reduced at the crusher The inner surface of the eccentric bushing is machined off centre from the centre axis of the crusher
CRUSHER is classified into various types according to the size of crushed material COARSE CRUSHER Crusher to crush the largest crusher SECONDARY CRUSHER crusher to crush the thin parts PULVERIZER CRUSHER to grind raw material with diameter less than 1cm into size powder
the throw of a cone crusher is set by the degree of eccentricity of the eccentric member which transforms the rotational motion of a drive member into the gyrating motion of the head and mantle It is possible however to vary the throw of the cone crusher To change the throw in such a typical cone crusher an eccentric member with a different degree of eccentricity must be
Eccentric motion is achieved by the lower eccentric bushing and drive arrangement on the bottom of the main shaft The input pinion drive countershaft is supported by pinion bearings and powered by an electric motor An external gearbox or belt drive arrangement reduces the motor speed to approximately 100 200 RPM at the crusher
·Currently in the primary crushing stage commonly used crushers include jaw crushers and gyratory crushers Recently FLSmidth 2022 has introduced an eccentric roll crusher which has gained favor in the crushing industry due to its high efficiency and energy saving advantages They are widely used for primary crushing of ores such as iron and copper
·The symmetrical arrangement of the roll allows the crusher to be balanced with great precision which significantly reduces machine vibrations and loads on surrounding structures and makes the crusher also ideal for use in mobile and semi mobile crushing systems A patented fully hydraulic gap setting/ retraction
·The eccentric and hydraulic support mechanisms are serviced from underneath the crusher without disturbing any of the feeding arrangements or the upper part of the crusher In all phases of its design the Hydrocone crusher has been built so that it can be serviced and put back into operation with a minimum of downtime and maintenance expense
·The symmetric arrangement of the roll permits the eccentric roll crusher to be balanced with great precision With additional balancing weights it can be balanced almost completely This lowers machine vibrations when idling and significantly reduces the loads on surrounding structures compared with other primary crushers
·A gyratory mill is similar to a jaw crusher and consists of a concave surface and conical head lined with manganese Material travels downward between the surfaces being progressively crushed until small enough to fall out The inner cone has a slight circular movement generated by an eccentric arrangement to crush material Gyratory mills can be used for
