Most of the spiral classifier and the grinding machine form a closed-circuit work, so as to separate the qualified crystals in time, and a few equipments are used for ore washing or desliming and dehydration of the ore pulp. The machine is equipped with a device for lifting and transporting grit. The size of the spiral classifier is expressed in diameter. According to the number of spirals, it can

The ball mill is supported on the main bearing through the hollow shafts at both ends. Among the two hollow journals, one can be axially extended and retracted on the main bearing, and the other is fixed. Since the gear drive of the ball mill will generate centripetal force, a hollow journal is designed with two shoulders, and the distance between the shoulders is exactly equal to the length of th

Although the classification process of high-frequency fine screen is similar to that of ordinary mechanical vibrating screening equipment, its classification principle is not exactly the same. (1) The ordinary vibrating screen adopts a single-layer sieve plate or screen, and the grading size is basically equal to the size of the sieve hole, while the high-frequency fine screen adopts a laminated s

Ball mills can be divided into grid-type ball mills and overflow-type ball mills according to different discharge methods. They are the most common mills used in concentrators at present. Conical ball mills are eliminated due to their low productivity, many types of linings and difficult maintenance. It is still used in some old concentrators. Among them, the overflow type ball mill is mainly comp

In the self-grinding process, the raw ore is both the grinding medium and the material to be ground. Due to the former feature, when the particle size composition of the raw ore changes, it is like the change of the ball-to-charge ratio in the ball mill. The productivity and product particle size of the autogenous mill change accordingly, due to the latter feature, when the composition of the raw

Dry self-grinding is different from wet self-grinding, but the working principle is basically similar. They all require a stable feeding amount and a certain ratio between large and small nuggets. With the rotation of the cylinder, the large and small ore blocks are lifted to a certain height, and then thrown down to produce a certain impact grinding effect to grind the ore. On the one hand, the l

Since the work of the jaw crusher is periodic, the load of the motor will inevitably change periodically, resulting in an extremely unbalanced load. Therefore, large crushers are generally provided with a flywheel at each end of the eccentric shaft (one of the flywheels is also used as a pulley), while the flywheel of small and medium-sized crushers can be made one. According to the principle of

The structure of jaw crusher is relatively simple, mainly composed of frame, DS working mechanism, transmission mechanism, adjustment device, safety device and lubrication system. The following takes the 900mm × 1200mm simple pendulum jaw crusher (Figure 1) as an example to briefly introduce its structure. 1) Rack There are two types of jaw crusher: integral frame and combined frame. The overall
