The crushing complex includes a feeder 1, a crusher 2, a medium crushing, a conveyor 3, a crusher 4 of fine crushing, a distributor 5 with a movable working body made in the form of a rotary 6, screens 7 and 8 with different sizes of screening surfaces (on screen 7 6f) njero screening surface size, for example, a grid with a 1PIMI large 70 mm diameter hole and screen 8 with a screening screen size, for example, a mesh with a 40mm diameter hole).

In addition, there are conveyors 9 and 10, sensors 11 13 measuring the operating parameters of a crusher. 1 (vibratory speeds of the crusher body, engine load and material levels in it), the outputs of which are connected to the input of the regulator 14, the output of which, in turn, is connected to the input of the actuator 15 that moves HJiber 6. There is also a setting unit 16 the position of the ninber corresponding to the specified granulated composition of the sublattice product, and the sensor 17 of the actual position of P1iber 6, the outputs of which are connected to the input of the regulator 18, the output of which, in turn, is connected to the input of the regulating device The size of the unloading nie.iH 19 crusher is medium crushing 2. In addition, there is a sensor 20 of the actual granular composition of the sub-product for the fine fraction and unit 21 of a given granular composition of the sub-product, whose outputs are connected to the input of the regulator 18, the output of which, in turn, connected to the inlet of a device for regulating the size of the discharge gap 23 of the crusher 2 of medium crushing.

(According to the proposed method, the starting material of the crushing is fed to the process line by the feeder 1 through the crusher 2 of the medium crushing to the conveyor 3, where it is mixed with the crushing products of the crusher 4 of the crushing and fed to the distributor by means of the distributor 5. In the distributor, the crushed material is used by the working body, for example with a clamp 6, they are distributed between screens 7 and 8. On screen 7 there is a screening surface of a larger standard size, for example, a mesh with large apertures 70 mm in diameter, and on screen 8 is a screening surface of a smaller size, for example a wire with smaller holes 40 mm in diameter, the screening product is combined and conveyor 9 is fed to the crusher 4 for fine crushing for re-crushing. The screener product 7 and 8 are also combined and conveyor 10 is fed to the compartment sorting, where the rubble is divided into commodity fractions.

With the start-up fraction | flax1ch kon n. IeKca, with sensors 11 3, measures the operating parameters of the crusher 4 for fine crushing (vibration velocity of the crusher body, engine load | -body and material level in it), signal. 1W from which the regulator 14 enters. In addition, the regulator 14 receives signals from the setters (not shown) with information about the optimal values of the specified parameters, where they are compared with the sensor signals 11–13, on the basis of which the controller 14 generates the control signals and delivers them to the actuator 15. The actuator 15 moves Piaber 6, which redistributes the material between screens 7 and 8, changing the performance of the screens over the target product so as to ensure constant operation of the shot Lki 4 me.1kk splitting pa full power. At the same time, the setting device 16 in the control system sets the information about this position of the H1ber 6 of the distribution device 5, which corresponds to the specified granular composition of the undersize product. Then, during the operation of the crushing complex, the sensor 17 continuously measures the actual position of the splitter 6 and sends a signal to the input of the controller 18. In the controller 18, the signal from the sensor 17 is compared with the signal of the setting device 16 and a signal is generated by the yiipaB.ieiiHH device with a size control device (11 slit) 19 crushers for the shot fractional cuts 2. Adjusting the size of the unloading unit; n1 crushers 2 are directly proportional to the change in the amount of material guided on the screen, 1, the surface is smaller - Hiero, size 8, RAMI, for example during operation, the gate 6 was rejected in such a way that the proportion of the material distributed to the screening surface of a larger size increased, and the share of the material distributed to the screening surface of a smaller size decreased accordingly, this should be considered as a consequence of the increased vibration velocity of the crusher 4 of the fine crushing above a predetermined value due to the large size of the material of the oversize product. In this case, the control signal of the regulator 18 reduces the size of the discharge gap of the crusher 2 medium crushing, reducing the size of the material supplied to the screening surfaces of the screen. As a result, the particle size of the oversize product returned for repartitioning, as well as its quantity, decreases and, as a result, decreases the lateral velocity of the crusher body 4. When the vibration velocity drops below a predetermined value, the gate 6 will begin to move in the direction of increasing the number of material supplied to the position corresponding to the specified

the composition of the undersize product and controlled by the sensor 17.

If during operation, the gate 6 was rejected in such a way that the proportion of material distributed to the screening surface of a larger size decreased, and the proportion of material distributed to the screening surface of the standard size increased accordingly, then this should be considered as a consequence of a decrease ( neither the vibration velocity of the body of the crusher 4 is below a predetermined value due to the reduction in the size of the material of the oversize product. In this case, the signal from the regulator 18 increases the size of the discharge gap of the crusher 2 average 1 o other depletion, increasing the size of the material supplied to the screening screen surfaces. As a result, the nodule 1a returned for re-crushing, as well as its quantity, increases, causing an increase in the vibration velocity of the crusher body 4. When the magnitude of the vibration velocity becomes BYN1C of the specified value, 6 the signals from the vibration velocity sensor will begin to shift in the direction of decreasing the amount of material supplied to the iroseivuyundie surface of a smaller size, and returns to the specified position , Corresponding stvuyun1ee given granular composition gyudren1etnogo product and controlled by the sensor 17.

Simultaneously with the monitoring of the actual position of the gate 6, the actual granulated pump is continuously measured by the sensor 20 of the granular composition to the process of the crushing complex's operation.

O

Tav of the cumulative under-cellet product of screens 7 and 8 and nodayut on the regulator 22 signals proportional to the content of small fractions. Here, this signal is compared with the signal of the setting device 21 and a control signal is generated, which is proportional to the critical deviation between the actual and the specified content of fine fractions in the crushing product. From the controller 22, a control signal is applied to the size control device of the discharge gap 23 of the crusher 4, which regulates the size of the discharge gap in direct proportion to the change in the total under-let product of the fraction of fine particles. If, for example, the sensor 20 detects a decrease in the content of fine fractions in comparison with a predetermined value of 21, then the size of the discharge gap of the crusher is 4 y. Since the sensor 20 detects an increase in the content of fine fractions, the size of the discharge gap of the crusher 4 is increased to obtain a sub-product with a predetermined content of fine fractions.

Using the proposed method for regulating the crushing complex allows for the regulation of the granular composition of the material supplied from the crushers of fine and medium crushing to screening, within the closed loop "crushing - screening, resulting in a reduction in the time spent in the control loop and increasing the control accuracy, which allows an increase in the yield of scarce fines by 2% in the sublattice product of a given 1-spin composition.
