Commonly used tin ore washing and grading equipment

The tin ore beneficiation process is roughly divided into four links: crushing, pre-selection, flotation, and re-selection. The connection between each stage is appropriate. Only when the equipment configuration is reasonable, the whole process of tin ore beneficiation technology will be smoother and more convenient to operate.

1. Crushing and screening

The nature of the tin ore is relatively simple, and a simple one-step crushing with a jaw crusher can achieve good results. The ore is crushed to 20mm, and then screened into two particle sizes of 20-4mm and 4-0mm. After crushing, the tin ore particles are uniform in size, beautiful in shape, and without over-crushing, providing high-quality raw materials for the next link, reducing the load of the grinding equipment, and having a good promoting effect on improving the grade of tin concentrate.

2. Pre-selection

The 20-4mm ore enters the heavy medium cyclone for pre-selection, and then after a rod mill, the jig is used for pre-selection. The jig tailings are screened with a 2mm vibrating screen, and +2mm is screened out as waste tailings, and -2mm enters the shaking table for selection.

3. Mixed flotation

After the tin ore separated by jigging and shaking table is re-grinded, mixed flotation is carried out, and the tailings of mixed flotation are sent to the shaking table for selection to produce qualified tin concentrate.

Chromite purification processing method

At present, chromium ores with industrial value are generally chromium-magnesia spinel or chromium-iron spinel minerals, which contain a large amount of chromium oxide, with a content of about 18% to 62%, and generally also contain metals such as aluminum and nickel. Its characteristics make the chromium ore beneficiation process present a rich and diverse state. Due to the properties of chromium, chromium ore beneficiation processes include gravity separation, magnetic separation, flotation, combined beneficiation, chemical beneficiation, etc. Commonly used in industry are single gravity separation, single magnetic separation, and gravity-magnetic combined beneficiation processes. In terms of equipment selection, shakers and jigs are mostly used in the gravity separation stage, while the equipment selection in the magnetic separation stage is determined based on the magnetism of the ore.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

The classifications of quartz sand

1. Ordinary quartz sand: The surface of ordinary quartz sand seems to have a layer of yellow skin, and some have large particles and strong fire resistance. It is a kind of quartz sand processed by the manufacturer after using natural quartz ore in the production process, such as washing and drying. No impurities can be seen in the quartz sand through the second water treatment filtration. It is the best choice for chemical water treatment. It can block the sundries suspended in the water and maintain the quality and beauty of the water. 2. Refined quartz sand: Refined quartz sand is a mineral made by the manufacturer after carefully selected quartz stone. According to different requirements of users, the range used is also different. But generally the main use of refined quartz sand is in glass products, because refined quartz sand is refractory and precision casting, especially suitable for fireproof glass materials.
