Ore pass screw

1. The advantages of spiral concentrator and spiral chute are as follows: 1) simple structure, no moving parts, easy equipment manufacturing and maintenance; ② The proction capacity per unit area is large and the floor area is small; ③ The material zoning is obvious and the sorting index is high; ④ It has strong adaptability, and has little influence on the separation indexes when the feed quantity, feed concentration, feed particle size and raw ore grade change
its disadvantage is that the enrichment ratio of flaky ore is lower than that of shaker and chute, and its own parameters are not easy to adjust to adapt to the change of ore feeding properties
the spiral concentrator is suitable for treating alluvial placer, especially for those with high dissociation degree and flat shape of useful mineral monomer. For resial and slope placer, the recovery rate is lower. In addition, the ore with high mud content will rece the quality of concentrate, so it is required to enter the spiral concentrator and spiral chute after desliming and classification
the spiral washer and spiral chute are mostly used to treat cassiterite, scheelite, chromite, ilmenite, sillimanite, monazite and other minerals, and can also be used to recover heavy minerals from flotation tailings. Generally, it is used as roughing equipment, which can discard most of the tailings to get coarse concentrate. The particle size range of spiral concentrator is generally 2-0.05 mm, up to 6 mm, and the effective separation particle size is 1-0.1 mm. The spiral chute, which is the same type as the spiral concentrator, is suitable for treating fine materials and iron ore successfully. The experimental results show that the effective recovery particle size limit of spiral chute is 20 μ M. This information is provided by www.gyxxjx.com provide

2. The separation principle of spiral chute and spiral concentrator is the same, and the equipment structure is also similar
(1) the main difference is that the cross-section shape of spiral groove is different. The cross section of spiral groove of spiral concentrator is approximate ellipse, which is suitable for separating coarse iron ore; The cross section of spiral chute is cubic parabola, and the bottom of spiral chute is wide and gentle, which is suitable for separating fine ore and slime. At present, spiral chute is widely used< (2) spiral washing machine and spiral chute are mostly used to treat cassiterite, scheelite, chromite, ilmenite, hollite, monazite and other minerals, and can also be used to recover heavy minerals from flotation tailings. Generally, it is used as roughing equipment, which can discard most of the tailings to get coarse concentrate. The particle size range of spiral concentrator is generally 2-0.05 mm, up to 6 mm, and the effective separation particle size is 1-0.1 mm. The spiral chute, which is the same type as the spiral concentrator, is suitable for treating fine materials and iron ore successfully.

Compared with gtx960, gtx960 has better performance, about 10% better than gtx1050. However, the power consumption of gtx960 is larger than gtx1050. Gtx1050 does not need external power supply, but gtx960 needs external power supply, The following is the comparison of the parameters of the two graphics cards:

4. It's not a proct
FRP spiral chute is an equipment that integrates the characteristics of spiral concentrator, spiral chute, shaker and centrifugal concentrator. It is the best equipment for mining and beneficiation, especially for sand mining on seashore, riverside, sand beach and stream channel. The proct has the characteristics of reasonable structure, simple installation, small floor area, simple operation, stable beneficiation, clear ore separation, large processing capacity, high efficiency, high beneficiation enrichment ratio, high recovery rate and reliable operation. It has the advantages of light weight, moisture-proof, rust proof, corrosion resistance, strong adaptability to the fluctuation of ore feeding amount and concentration, particle size and grade, and no noise
the spiral concentrator is a machine composed of a long narrow groove spiraling around the vertical axis. The cross section of the tank is elliptical, and interceptors are installed in the tank. Concentrate and middling are taken out from the interceptors, and tailings are discharged from the tail of the tank.

5. In general, StarCraft 2 can only use two threads. I'm afraid the best CPUs today are 7700k and 7350k, with high frequency and new architecture.

6. Overflow screw feeder, which is a new type of screw feeder, is mainly used for conveying st, as well as a variety of powder, granular and other non viscous materials feeding, so in metallurgy, chemical instry, building materials, coal and other instries, has a very wide range of applications.

The structure of spiral concentrator is shown in Figure 38. It is made by bending a chute around the vertical axis into a spiral shape. The spiral has 3-5 circles and is fixed on the vertical support. The section of the spiral groove is a part of parabola or ellipse, and the bottom of the groove has a certain inclination in the longitudinal (along the direction of ore flow) and transverse (radial). Starting from the second circle, there are about 4-6 heavy proct discharge pipes at the middle part of the trough bottom. The upper part of the discharge pipe is equipped with a interceptor, which can intercept the heavy ore flow into the discharge pipe for discharge. The two scrapers of the interceptor are pressed on the trough surface, and the movable scraper can be rotated to adjust the opening angle between the two scrapers, so as to adjust the discharge of heavy minerals, As shown in Figure 39. In order to improve the quality of the heavy proct, there are several water adding points on the inner edge of the tank, called washing water, which is fed into the inner edge of the tank by the central water pipe through the valve

In the process of separation, the slurry is evenly fed from the upper homogenizer along the width of the trough, the slurry is stratified in the process of flowing along the trough, and the heavy minerals enter the bottom and move to the inner edge of the trough under the combined action of various forces; The light minerals are thrown to the outer edge in the rapid rotary movement. As a result, the ore grains with different densities are divided into zones in the transverse direction of the trough, as shown in Fig. 40. The heavy minerals flowing along the inner edge of the tank are intercepted by the interceptor and discharged through the discharge pipe. The quality of the heavy procts from the first to the second discharge pipe above is the highest, and the quality of the heavy procts below is lower. The washing water added in the inner edge of the tank flushes some light minerals mixed with heavy procts to the outer edge, which is concive to improving the quality of concentrate. The tailings are discharged from the end of the lowest tank

8. Only from the effect of mineral processing, the shaking table must be better, with high grade and high recovery.

9. Spiral chute belongs to gravity separation equipment, the biggest advantage of spiral chute is energy saving, no noise pollution, no pollution, it can be said that it is a lifetime investment income, the failure rate is also very low!

Matters needing attention in selection of screw conveyor for Mining:

1. screw conveyor, commonly known as auger, is a kind of conveyor equipment widely used in mining, feed, grain and oil, and construction instry. From the perspective of conveying material displacement direction, screw conveyor can be divided into two types: horizontal screw conveyor and inclined screw conveyor, which are mainly used for conveying various kinds of powder, grain and oil Horizontal conveying and lifting of granular and small loose materials

   Screw conveyor is the main unit of mechanized transportation in instrial and agricultural departments. Screw conveyor can rece labor intensity and improve work efficiency, which has a wide range of applications
   The screw conveyor is not suitable for conveying perishable, viscous and caking materials, because these materials will stick to the screw and rotate without moving forward ring conveying, or form material accumulation at the suspension bearing, which makes the screw conveyor unable to work normally
   In view of the application scope and functional characteristics of screw conveyor, the user should fully consider, make overall consideration and reasonably select the type according to the use environment and conveying materials, so as to avoid unnecessary trouble and loss
   The manufacturer should allocate professional technicians to select models for customers, so as to avoid the misunderstanding of customers. Make screw conveyor give full play to its role
