Silicon carbide mill performance characteristics and working principle
Silicon carbide mill production process
National silicon carbide mill is widely used assault crushing process. Silicon carbide devices such processes both in the first - in the second paragraph, it points to elect the three products: concentrates, ores and tailings, sorting 35 to 16 cents surgery and 16-0 mm classification of materials. Silicon carbide production equipment in the third paragraph on the mine and then broken and supplement selection. With dry magnetic separation of the three-stage crushing process - form over a period of fragmentation and sub-elected Sec broken tailings. Silicon carbide mill sieve product crushing, screening under the product for qualified broken products. When dealing with rich ore in some selected plant, after a broken silicon carbide devices can be divided to elect qualified concentrate. Including closed-circuit crushing of dry magnetic separation process should adopt the three sections of the process. This process is mainly used for the skarn-type magnetite ore gangue broken when dissociation. Silicon carbide mill is the most common three sections of the closed-circuit crushing process is a period of dry magnetic separation points to the election of a disused tailings. Sorting sieve products in other countries, some of the processing plant. Silicon carbide production equipment is also used points to elect the three products in concentrates, tailings, and ore sorting process, and sometimes fine-grained level (16-0 mm). Including closed-circuit crushing of dry magnetic separation process but the ore is deep-election to prepare effective technical solutions. Broken silicon carbide devices containing thousands of magnetic separation process is characterized by dry-type sorting the actual seven sorting coarse-grained (sieve dagger) materials. Sorting without the classification of materials trying to prove that the tail mineral rate and fine-grained wet material adheres to the separator drum E, so that ore depleted, the separator can not be effective and reliable work. Therefore, in recent years, special attention to the transformation of the dry magnetic separation structure. At present, some of the structure of the magnetic separator used for the preselection of magnetite quartzite (the Soviet Union's main iron ore raw materials). However, due to the dissociation of this type of ore in the broken low, the need for the specific case of application of dry magnetic separation of technical and economic research in order to determine to ensure that the living process This job is a reasonable limit dissociation degrees. The effectiveness of the magnetite ore Dry to determine the equilibrium conditions based on live process and should not be used: silicon carbide mill depot magnetic choose to do one ton of ore product sales profit.
Silicon carbide production equipment, production process
Silicon carbide production equipment to dry a the tailings minimum yield depends mainly on the cost of a broken and the cost of dry magnetic separation process. Silicon carbide device is dry tailings can be used as building materials for conditions derived. In the case of tailings are not suitable for construction purposes, dry magnetic separation only by reducing the grinding and the section of the beneficiation process costs to influence the cost of concentrate. The commodity tail mineral rate of not less than 5%, the application of dry magnetic separation sorting dip-shaped magnetite ore justified i broken particle size of 30-0 mm, silicon carbide mill manufacturers for most of the ore types , noise can not permit the production rate. Smaller closed-circuit crushing the ore, ore particle size down to 16-0 mm.
The production process of silicon carbide devices
The requirements of the broken materials, silicon carbide devices broken the requirements of the material depends on the next step of the sub-materials processing operations: milling, autogenous grinding. Silicon carbide mill for crushing the ore was selected to prepare the final stage of the mill, broken the requirements of the material depends on the ore granularity of the dissociation degree of the obtained concentrates or goods ore. Milling, the main requirements of the broken material is the size of ore, ore dissociation degree and mix. Ore particle size of the mill's production capacity, is the most important factor - the grinding equipment, ball mill feed size, most of the 20 (16) 10 mm. Silicon carbide devices to further reduce the to Kuang particle size is reasonable, but limited by the technical possibilities of crushing equipment. In this case, the cost of grinding to reduce the crushing costs increase 12. When the broken particle size of 11-0 mm, the most reasonable cost. Milling on the broken ore the most important requirements for the degree of dissociation of the ore. The degree of dissociation is smaller, the greater of the ball mill according to the dissociation of material total production capacity ball mill to the dissociation of metal minerals and non-metallic mineral form of accumulated material is the less. Pre-dry magnetic separation can be separated from the broken ore in the dissociation of non-metallic mineral, and sometimes isolated metallic minerals, so it is one of the important measures to improve the grinding equipment working conditions. Ore mix can not only make the first paragraph of the grinding process and stability, but also an important impact on the ore processing in the future. For the magnetite ore milling and grinding, this effect is small. The quality of raw material of silicon carbide production equipment depends not only on the stability of the mine storage capacity, but also depends on the number of ore types and the difference between them. Have significant impact on the fluctuations in ore grade iron ore dressing indicators. Silicon carbide ore grade fluctuations from 29 "dropped l mantra, the rate of fine mineral increased by 0.04,0.59 e-iron recovery in the concentrate increased by 0.5 to 1.2%. The beneficiation Section, silicon carbide mill crushing ore quality and uniformity to the Tu-stability is one of the concentrator collaborative working conditions.
