Cone Crusher is one of the main types of primary crushers in a mine or ore processing plant. Cone crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory cone crushers can be used for primary or secondary crushing.The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric on the bottom of the spindle that causes the central vertical spindle to gyrate. The vertical spindle is free to rotate around its own axis.
The crusher illustrated is a suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. After the materials has slid straight down a brief distance, the bigger lumps or masses in the materials are crushed into scaled-down masses through the result developed when these lumps are caught in between the crushing mind wall as nicely as the interior wall in the mantle jacket, since the mind techniques a portion in the mantle wall. once the mind retracts soon after obtaining shipped the impact, the materials goes on to slip straight down and distribute out for the flaring wall in the mind along a training course bounded through the adjacent mind and mantle walls, till an additional result is shipped through the head. Soon after each and every succeeding result the crushed materials gets scaled-down and slides along and spreads out into an place in the tapered cavity obtaining a scaled-down spacing in between its walls. The last sizing in the crushed merchandise is determined through the spacing in between the walls on the reduce finish in the crushing cavity, once the mind is in its placement closest for the mantle.
The sizing in the crushed merchandise might be regulated by raising or lowering the mantle by implies in the sprocket nuts, and thus raising or decreasing the cross part in the crushing cavity. The materials being crushed is fed to the hopper, from in which it drops onto the crushing mind and begins to slide straight down the outwardly slanting wall thereof.
