1.
Vibrating feeder: if the ore is evenly broken, small in size and good in fluidity, swing type or wave type can be selected. It is suitable for elliptical vibration type and directional vibration type
double mass vibrating feeder: the principle of double mass near resonance inertial vibration is adopted. Single row or double row shear rubber springs are arranged at the top and bottom, and the lower pressing plate is connected to the balance body by bolts, and then the left and right side plates are connected with the groove body. It has compact structure, stable starting under constant pressure, and is not affected by the load and jamming of the tank material. The feeding particle size (0-850mm) is large (8-1800t / h). It can be equipped with stepless frequency converter to realize frequency conversion feeding and batching, and remote microcomputer operation and control

3. 1. Fixed screen
the working part is fixed and the material is screened by sliding along the working face. Fixed grid screen is widely used in concentrator, generally used for pre screening before coarse crushing or medium crushing. The utility model has the advantages of simple structure and convenient manufacture. Without power consumption, the ore can be directly discharged to the screen surface. The main disadvantages are low proctivity and screening efficiency, generally only 50-60%
there are two kinds of fixed screen: lattice screen and strip screen
the lattice screen is installed on the upper part of the coarse ore bin to ensure that the feeding block size of the coarse crusher is appropriate. The large blocks on the lattice screen need to be broken by hand hammer or other methods to pass the screen. The fixed screen is generally installed horizontally
the bar screen is mainly used for pre screening before coarse crushing and medium crushing. Generally, it is installed at an inclined angle. The inclination angle should enable the material to slide down automatically along the screen surface, that is, the inclination angle should be greater than the friction angle between the material and the screen surface. Generally, the dip angle is 40 °— fifty ° For large ore, the dip angle can be slightly reced, while for viscous ore, the dip angle should be slightly increased
the mesh size of the bar screen is about 1.1-1.2 times of the required particle size under the screen. Generally, the mesh size is not less than 50 mm
the width of the screen depends on the width of the feeder, conveyor and crusher; And it should be 2.5 times larger than the largest block size in the feed
2. Roller screen
the working face is composed of horizontally arranged rolling shafts with plates on which fine materials pass through the gaps between rollers or plates. The bulk material moves from the roller belt to one end and is discharged from the end. This kind of sieve is seldom used in concentrators
the screen surface of roller screen is composed of a number of rollers arranged in parallel and staggered with screen plates. The rollers rotate through sprocket or gear transmission, and the rotation direction is the same as the material flow direction. In order to make the material layer on the screen loose and easy to pass through the screen, the shape of the screen plate is eccentric and irregular. In order to prevent the material from jamming the screen shaft, a safety device is installed. All roller screens are seat type, which can be divided into left drive and right drive, and can be divided into take-off wheel and non take-off wheel. The take-off wheel can move on the rail. Roller screen is a relatively backward old screening equipment with complex and bulky structure, which is being eliminated. Metal mines are mostly replaced by heavy vibrating screen, but some old users such as coal department are still used to using this equipment
working principle: because the screen shaft is arranged according to different working angles, the speed is faster when the material runs in the position with higher working angle; When the material runs at a lower working angle, the speed is gentle. When the two kinds of wood run at the same speed, the materials begin to move axially when they meet at a certain position on the screen surface, so that the materials are evenly distributed on the screen surface, and the purpose of improving the screening efficiency is achieved
3. The working part of the cylindrical screen is cylindrical, the whole screen rotates around the axis of the cylinder, and the axis is generally installed with a small inclination angle. The material is fed in from one end of the cylinder, the fine material passes through the sieve hole on the working surface of the cylinder, and the coarse material is discharged from the other end of the cylinder. The rotary speed of the cylinder screen is very low, the work is stable and the power balance is good. But the screen hole is easy to block, the screening efficiency is low, the working area is small, and the proctivity is low. Concentrators rarely use it as screening equipment

4. Plane motion screen
the body is a plane swing or vibration. According to its plane motion trajectory, it can be divided into linear motion, circular motion, elliptical motion and complex motion. Shaker and shaker belong to this category
the crank connecting rod mechanism is used as the transmission part of the shaker screen. The motor drives the eccentric shaft to rotate through the belt and pulley, and makes the body move back and forth in a certain direction through the connecting rod. The movement direction of the machine body is perpendicular to the center line of the strut or the suspender. Due to the swing movement of the machine body, the material on the screen surface moves to the discharge end at a certain speed, and the material is screened at the same time
compared with the above-mentioned sieves, the shaker screen has higher proctivity and screening efficiency. Its disadvantage is poor dynamic balance. Now, it is rarely used in concentrator, and is replaced by vibrating screen with more reasonable structure
vibrating screen is widely used in mineral processing plants. According to its different transmission mechanism, it can be divided into the following types: eccentric vibrating screen, inertial vibrating screen, self centering vibrating screen and resonance screen.

The double axis vibrating screen is excited by the double unbalanced weight of synchronous opposite rotation, the screen surface is horizontal or gently inclined, and the motion track of the screen box is linear. There are inertia vibrating screen, eccentric vibrating screen, self centering vibrating screen and electromagnetic vibrating screen< Br > linear vibrating screen: < br > vibrating screen is a kind of screening machine widely used in coal and other instries for material classification, washing, dehydration and medium removal. Among them, linear vibrating screen is widely used because of its high proction efficiency, good classification effect and convenient maintenance. In the working process, the dynamic performance of vibrating screen directly affects the screening efficiency and service life. The vibrating screen uses the vibrating motor as the vibration source to make the material thrown up on the screen and move forward in a straight line at the same time. The material evenly enters the feed port of the screening machine from the feeder, and proces several specifications of materials on the screen and under the screen through the multi-layer screen, which are respectively discharged from their respective outlets.
