Barite re-election process

the process of processing 80 tons of barite beneficiation process:

Our factory has rich experience and unique insights on gravity sorting of barite ore. According to our experience in the field of barite re-election for many years, we have designed 80 tons of barite beneficiation process for Kenya customers. The details are as follows:

Introduction to barite beneficiation process:

The beneficiation process is a re-election process, and the jig is used as the main equipment for the separation and purification of barite ore. The process flow is described in detail below.

①crushing process

The barite is brittle and brittle. Therefore, the crushing process mainly adopts a simple and practical jaw crusher. The two-stage crushing process is used to crush the mined barite, so that it can reach the effective size range of the jig. A piece of crushing is recommended to use PE400*600 jaw crusher, and the second section of crushing is recommended to use PEF250*1000 fine jaw crusher.

After a piece of crushing, the product is conveyed by a belt conveyor to a second-stage fine jaw crusher for re-crushing to meet the selected grain size requirements of the subsequent sorting equipment. Since the customer requires no dust during the production process, it is recommended to add water properly in the crushing process to reduce the dust generated when the crusher works.

②Screening process

Jig sorting requires strict material size, and is generally required to be graded to achieve better beneficiation index and higher processing capacity. Therefore, in the barite re-election process, a screening process is required to screen the broken product. According to the treatment, the crushed products are divided into different grades to enter the jig for jigging sorting.

The screening process adopts a circular vibrating screen with large processing capacity, high screening efficiency and simple and practical. This type of vibrating screen has low failure rate, large processing capacity, high screening efficiency and easy operation. It is an ideal equipment for barite ore screening. . Since the screening process also produces a certain amount of dust, it is recommended to set up hydration in the process to reduce the generation of dust.

③Buffering process

The jig needs uniform and stable feeding amount during normal operation. Therefore, it is better to set up the mechanism and equipment for buffering before the jig, such as silo and vibrating feeder. The function of the silo is to avoid the work of the previous equipment. The quantity is suddenly large and small, and there is a certain amount of material in the medium, and the function of the vibrating feeder is to uniformly and stably feed the jig material. The existence of these two auxiliary equipment is crucial for the normal and efficient operation of the subsequent jig. Important role.

The silo of No. 1-4 adopts the silo of 15m3, and the silo of No. 5 adopts the silo of 25m3. For the convenience of transportation, the silo designed and produced by our factory is a combined removable silo. The vibrating feeders all use the GZ3 electromagnetic vibrating feeder.

④Jigging sorting process

According to the customer's request, we use two types of jigs to sort the crushed barite material. Because of the inevitable production of fine materials during the crushing process, it is recommended to use two types of jigs. The coarse and fine materials are separately sorted. The No. 1-4 jig uses a coarse-grain AM30 jig for processing 10-30mm coarse-grain barite ore. The No. 5 jig uses 2LTC-6109/8T jig to process 0-10mm fine Granite barite ore.

The concentrate produced by the No. 1-4 jig is fed into the 10-30mm grain-level concentrate pool through pipes or chutes, and the concentrate produced by the No. 5 jig is transferred into the 0-10mm grain-level concentrate pool. The tailings produced by all the jigs are transferred to the tailings pond and are transported away by a forklift or conveyor.

⑤Dehydration process

Since the customer requires mechanical dewatering, the dewatering process can be dewatered with the simplest sedimentation. It is also possible to design a suitable mechanical dewatering solution according to requirements.

⑥Water circulation process

The jig has a large amount of water, and generally uses circulating water. Therefore, it is necessary to design a water circulation scheme according to the specific conditions of the customer's site to ensure the normal and effective process.

The principle and process of selecting the barite from the jig:

The principle of selecting the barite from the jig is based on the difference in specific gravity between the barite and its associated gangue, and the barite that is stratified by the specific gravity in the vertical flow generated by the swelling water of the jig is a barite with a large specific gravity. The sedimentation speed in the vertical alternating water flow is faster, located in the lower layer of the jig sorting tank, and the gangue mineral with smaller specific gravity occupies the upper layer of the sorting tank, and is discharged out of the machine through a special discharging device to obtain the specific gravity. Two minerals of different sizes, namely concentrates and tailings.

The barite ore is stably and evenly fed into the jig through the silo and the feeder, and is layered according to the density in the alternating water flow generated by the jetting of the jig, and the barite has a large specific gravity and occupies in the stratification process. The lower space of the sorting tank has a small specific gravity of the gangue, and occupies the upper space in the stratification process. The two materials with different specific gravities are respectively discharged through a special material distributing device, and two materials with different specific gravities are obtained, that is, heavy Crystal concentrate and tailings.
