Tajikistan is an important mining machine market for every mining equipment manufacturer. Also for crusher machine. In the past few years, Our mining equipment helped Tajikistan to be significant to world mineral markets as a gold producer. Especially in the antimony mining, Tajikistan possessing the largest deposits of antimony in the former Soviet Union, and having more than 400 explored mineral deposits, containing 70 types of minerals largely brought crushing machines and grinding mills. Aluminum ore crusher, zinc ore crusher, lead ore crusher, chemicals, fertilizers, and cement mills were the top needing industries in the past few years, and aluminum ore crusher was the leading applying mining crusher.
In the mining of 2000 in Tajikistan, the gold mining crusher and mill production was 2,700 kg; gypsum crusher and mill production, 35,000 tons; and antimony ore crusher and mill production, 2,000 tons. Our crusher machines and grinding mills in Tajikistan also participate in producing bismuth, lead, mercury, silver, cement, and fluorspar. No copper, molybdenum, tungsten, or zinc has been produced by our crushers in recent years. Gold mining crushers and grinding mills was widely used in southeast of Gharm, in the Pamir Mountains, in the Yakhsu Valley, in Chkalovsk, and in the Jilau, Taror, and Aprelevka deposits; mercury ore crushers and industrial mills was widely used at the Dzhizhikrutskoye deposit, north of Dushanbe; antimony, at Isfara and Dzhizhikrutskoye. At the same time, other mining crushers are well used in Tajikistan.
A gyratory crusher is similar in basic concept to a jaw crusher, consisting of a concave surface and a conical head; both surfaces are typically lined with manganese steel surfaces. The inner cone has a slight circular movement, but does not rotate; the movement is generated by an eccentric arrangement. As with the jaw crusher, material travels downward between the two surfaces being progressively crushed until it is small enough to fall out through the gap between the two surfaces.
A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory 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 short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superseded the long-shaft design in which the eccentric is mounted below the gear.
