Installation angle of screw miner
1. Before the installation of the seat type drawing machine, the on-site foundation shall be compared with the drawing of the drawing machine. After the inspection, the steel plate shall be embedded. The thickness of the steel plate shall be 20 mm and the flatness shall not be greater than 1.5%
2. After the ore drawing machine is installed, adjust the relative position, and then weld the spring base and the embedded steel plate by spot welding
3. It is required that the two vibrating motors must turn in the opposite direction
4. After installation and running for 1 hour, check whether the body runs smoothly, the yaw is not more than 0.5mm, and the bolt fastening of the vibration motor
5. If the handling capacity is not enough, the exciting force of the vibration motor can be adjusted to achieve the best effect if it is allowed
6. Adjustment of exciting force: A. remove the protective cover; B. loosen the two inner eccentric blocks; C. adjust the two outer eccentric blocks in the same phase and at the same angle; D. tighten the adjusting bolts and install the protective cover; e. the temperature rise of the vibration motor bearing shall not be greater than 80oC (resistance method)
7. During the operation of the ore drawing machine, attention should be paid to whether the movement of the machine body is stable. If abnormal operation or abnormal sound is found, the machine should be stopped immediately for inspection. 8. The bearing of vibration motor shall be lubricated with 3 # lithium grease once a week. The bearing shall be inspected and cleaned once a year to check the wear degree of the bearing. If necessary, it shall be replaced and repaired in time
9. The fastening bolts of the connection parts should be checked frequently to eliminate the hidden danger in time
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
(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. The experimental results show that the effective recovery particle size limit of spiral chute is 20 μ M.
The ore washing machine is suitable for desliming operation of a large amount of sand and stone in construction sites, sand and stone plants, concrete prefabrication plants and hydropower construction sites, as well as for washing, grading and dewatering of ores. Ore washing can be carried out in scrubbing machine, screening and grading equipment
Hengcheng mineral processing gives you a detailed explanation of the working principle and operation theory of the spiral classifier:
1. The working principle of the spiral classifier is to feed the pulp into the U-shaped groove from the middle feed port on the side of the groove
2. The U-shaped groove makes the pulp flip back and forth, which will make the lighter particles fall at the bottom, while the heavier ones are located on the upper side, so as to separate the materials of different sizes and weights
The spiral classifier of mineral processing equipment is different from some other equipment for transporting grit, which can be divided into spiral classifier, rake classifier and floating trough classifier. The outstanding one here should belong to the spiral classifier. The main reason is that it has the characteristics of simple structure, convenient operation, large skew point of view and so on. It is easy to connect with the grinding machine for gravity flow, so it is widely used Second, the operation theory of spiral classifier of mineral processing equipmentother classifiers are distinguished by the size and weight of solid materials, so the settling velocity in liquid is different. Fine ore particles float in water and overflow, while coarse ore particles sink at the bottom of the tank. Spiral classifier is a kind of classification equipment for mechanical classification. Because it can be connected with the mill, it can grade and filter the raw materials from the mill, and then grade the coarse and fine materials. The base of this type of machine is made of steel groove, and the body is made of steel plate by welding, so the machine is very firm. The various parts of the spiral shaft use pig iron sleeve, so it is very wear-resistant. And its performance compared with other classifiers are also greatly improved, so it is widely used in proction
in addition, attention should be paid to the acidity and alkalinity of backwater
generally speaking, backwater has little effect on fineness, but has some effect on other flotation indexes
