This is a construction site in north Korea, undressed ore for mud, with gold for gold, capillary, not apply to ordinary fixed chute chute is inspired.

Impulse chute is in ordinary fixed chute developed on the basis of a sand gold to choose equipment. It integrated the advantages of fixed chute and jig, overcomes the drawback of fixed chute is easy to harden and jig large yield, to obtain the yield of small and not easy to harden this characteristic.

Encouraged chute basically retains the characteristics of the characteristics of the original fixed chute, and change the original iron plate to the rubber floor, plus simple crank connecting rod mechanism, make the upper and lower rubber floor do reciprocating motion, each slip case between diaphragm effect similar to the jig. To solve the phenomenon of slip, harden and improves the recovery rate of gold. Because the impulse chute is intermittent discharge concentration, so the yield is very small, enrichment ratio is higher than the jig dozens of times to hundreds.

lower than the chute bed surface, have the effect of buffer and allocation pulp, avoid direct impact bed pulp. Ore sorting will enter the chute. Slip is made from 40 * 40 Angle steel, Angle steel side and at the bottom of the chute and rubber connection into an organic whole, above 50 mm wide on welding steel plate, and the water is 0 degrees Angle, can make the produce large eddy current in the slurry flow. Grating on the elliptical hole is still processing, staggered, main effect is to make the light minerals in the plate under part sediments under the effect of encouraging from the eduction in hole, elliptical hole at the front is equipped with iron, prevent coarse gravel block elliptical hole.

Chute soleplate is made from natural rubber, rubber plate impulse is driven by motor reducer and crank connecting rod mechanism, make the rocker according to a certain point, forcing the bracket for upper and lower reciprocating motion, thus rubber sheet for upper and lower movement, through the reciprocating movement make heavy minerals in the pulp layer, loose sediments always maintain state, is advantageous to the heavy mineral recovery. Pulp after 2400 mm long separation process, heavy mineral and gold particles deposited on the bottom of the slip between the continuous discharge by the minerals from the tail. Due to the design on the slip, reciprocating mechanism, so that the chute during a long period of time to choose don't always keep a good state of separation.

Incited chute separation process was borrowed from the ordinary fixed chute and jig, the basic principle of the two devices. When the material under the effect of longitudinal flow, the pulp flows through a certain height and distance and through the elaborate design of the article, can produce whirlpools and pulsating flow, rotary motion of the vortices keep than the weight of the golden grain and other major mineral transferred to the bottom. Where the flow of the turbulent motion with abate, volume concentration reached a lot. Light mineral of large particles, therefore, it is difficult to enter, only thin heavy mineral particles through clearance into the bottom, formation sand bed. Due to continuous discharge chute concentrate is not, as the growth of the working time, slipped between the sediment is more and more dense (that is, the formation of harden sediments) which affect the mineral further stratification, is to choose don't get bad results. Encouraging chute make the floor produces, virtually every slip between the rubber sheet similar to the diaphragm jig, effectively solved the problems of bed harden. Jig separation is on the rise under the action of water flow so that bed, falling water suction effect, according to the proportion of mineral grain layer, heavy mineral drill clearance what level are recycled. While urging chute didn't added up the role of water, nor bed with people, but by a lot of rectangular diaphragm direct effects on sedimentary deposits and pulp, the diaphragm rises stage make the mineral grains rise, loose sediments from state, also produce certain suction when the diaphragm down, mineral particles according to the proportion of stratification. Natural golden proportion than gangue mineral times larger, so quickly drill gap to the underlying and recycled. Due to the case of the block and the protection of the natural bed, be recycled to the underlying nature of gold would not be pulp flow away again.
