Introduction:
The three ring medium speed superfine grinding machine is mainly used for processing non flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤ 6, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum More than 100 kinds of materials, such as alunite, graphite, fluorite, phosphate rock, potassium ore, pumice and so on, the fine powder particle size can be adjusted between 325-3000 mesh, and the output can reach 0.6-6.5 tons per hour.
The three ring superfine grinding machine is mainly used for grinding of mineral products such as metallurgy, building materials, chemical industry, mining and so on. It can grind quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate rock, iron oxide red, pyrophyllite, shale, purple sandstone, chlorite, stromatolite, basalt, gypsum Processing of graphite, silicon carbide, thermal insulation, materials and other non flammable and explosive mineral materials with Mohs hardness below grade 6 and humidity of 6%.The whole set of equipment consists of main engine, reducer, analyzer, pipeline device, blower, dust collector, jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control system, etc.
Advantage:
1. It has the advantages of high fineness, high output, low energy consumption and low investment. The comminution capacity of HCH superfine ring roller mill is more than twice that of similar equipment.
2. The equipment system is perfect, which can realize two processes of superfine grinding and superfine grading at the same time.
3. The fineness of finished products can be adjusted between 0.04-0.005mm (400-2500 mesh). The products with different fineness can better meet the market demand and improve the competitiveness of enterprises.
4. Environmental protection production: low noise, high dust removal efficiency and no dust pollution.
5. Equipment installation is very convenient, no need for large-scale civil engineering, the equipment can be put into production after installation.
6. The equipment runs stably and has reliable performance. It can produce continuously and normally. The fineness classification precision of the product is high and the product quality is good.
7. Low wear: wear parts are made of special wear-resistant materials, which can prolong the service life.
Working principle:
1.The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of roller which are rolling in the ring,which are driven by dial through plunger.
2.Big material is crushed into small particles by hammer crusher,and then small products enter the storage silo by the elevator,and finally the material is sent to bulk material plate by vibrating feeder and feeding pipe uniformly.
3.The material is scattered to the edge and fallen into the ring rolling,then it is impacted,rolled,grinded and turned into the powder by the ring. The air is sucked into the the machine by high pressure fan, the crushed material is put into the classifier.
4.Coarse materials is returned to grind again by the rotating blade, required fine powder entered the cyclone dust collector and dischareged by the discharge valve ,which is the final product. Airflow with some fine dust is discharged by the fan and silencer.
