Applied materials: various non-flammable and explosive minerals such as gypsum, talc, calcite, limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, iron ore, etc.
Raymond mill is a widely used mill machine for grinding coarse material into powder with different granularity. Its applications suit for many areas such as mining industry, gravel and quarry industry, chemical industry and construction waste recycling industry, and it can grind over 280 materials with Moh's hardness below 9.3 and humidity below 6%.
Raymond mill actually can be divided into two types of machines processing different materials. One is called Raymond vertical mill and the other is Raymond roller mill. The difference between them is that vertical grinding mill belongs to high-speed air swept swing hammer mill while the other belongs to air-swept vertical ring-roll mill.
Step 1The jaw crusher crushes large pieces of material into smaller particles within the feed size of the Raymond roller mill. The crushed materials, after passing through the bucket elevator, are sent into the storage hopper and vibrating feeder for being evenly and continuously ground in the main crushing chamber.
Step 3Then the power through wind pipe enters the powder collector for separating. The desired final powder product will be discharged from the discharging port while there would be another grinding for the undsired powder until it meets standard.
Raymond mill uses the design of the vertical structure with less occupied-place and a systematic working style. The whole process from coarse crushing, transportation, grinding to final packaging is an independent production system.
According to the original shockproof capacity of the Raymond mill equipment and its surrounding shake parameters, Fote experts upgraded a new shockproof material. During the searching process, they made the device by means of dynamic analysis of diaphragm-designed structures and theory of structural dynamics. Whats more, it is a good solution to the problem of over-larger vibration only with a smaller power.
They adopt the integral base of the host which makes the machine structure solid, reliable and strong seismic resistant. The design perfectly avoids the cracking or damage of components caused by long-time vibration and fatigue of framework and air return box.
The grinding roller and its shaft can complement each other, which means that the roller cannot only revolve but rotating. The part is engineered to improve the machines efficiency and durability even under greater grinding force and higher operating speed.
In the design of the whole system, Fote has changed the traditional two-stage collection to four-stage collection. The primary and secondary collections are collected by circulating negative pressure and there is no dust leakage. The third and fourth-level collections use controllable-overflow dry and wet collection to prevent dust overflow.

India is a country with abundant gypsum resources, India is important to the gypsum reserves and production. Many Indian customers found us and requested us for grinding production projects, especially for grinding gypsum powder.
In March 2019, an Indian customer contacted us to process ultra-fine gypsum powder, hoping to use it in production as soon as possible. After an on-the-spot investigation, our engineer introduced him with a gypsum production line that integrated feeding, crushing, grinding and dust collection.
"I really satisfied with the gypsum powder produced by Fote Raymond mill. Its white with even particle size. I'm a gypsum powder supplier, and committed to selling the high-quality product to my clients, so I have really high requirement on fine powder.
"Concrete mixed with coal slag has good water retention, plasticity, less bleeding, which means only high-quality product can bring me more money, and this Raymond grinding line did make me get considerable profit.
"When the fineness and output of quartz stone are the same to all machines, using Raymond mill can save nearly half of the power and increase the grinding output by about twice, which is amazing.
Raymond mill is suitable for processing non-metallic materials that are not too hard, such as limestone, gypsum, calcium carbonate; ball mills can process metal materials and hard materials such as potassium feldspar, quartz, metal ores, etc.
Raymond mill can only be used for dry grinding, which has a requirement of the material on the humidity; the ball mill can be used for wet grinding, so there is no limit to the materials on the humidity.

It is processable for cement clinker, quartz sand, feldspar, calcite, lime, limestone , dolomite, barite, graphite, gold and silver ore, rutile, titanium dioxide, kaolin, bentonite, aluminum ore, coke gemstone, fluorite, wollastonite, phosphate rock, rare earth, iron red, metal silicon, electrolysis , niobium alloy, silicon carbide, gold steel sand, smelting metal, calcium magnesium ore, coal, activated carbon, humic acid, carbon black, grass ash, coal gangue, slag, zircon sand, iron ore, iron fine powder, talc , granite, potash feldspar, marble, barite, wax feldspar, clay, glass, coke, petroleum coke, water slag, slag, fly ash, cement, pigment, clay, ceramsite sand, saline, muddy sand Milling materials such as additives, fire-fighting agents, curing agents, waste ceramics, waste bricks, refractory materials, aluminum ore, bauxite, etc.
Raymond Mill has been widely used in the processing of non-metallic minerals since its introduction to China for more than 20 years. However, with the extensive development of non-metallic minerals in the application of ultra-fine powders, downstream enterprises are increasingly demanding non-metallic mineral products, especially for product fineness, which makes traditional Raymond mills powerless. So Dalil Heavy Industry Technology Department has carried out in-depth analysis and research on traditional grinding machines, and solved many fatal defects such as frequent maintenance, high maintenance cost, and insufficient fineness of grinding, and developed a set. A new ultra-fine Raymond mill that is crushed, ground and ultra-fine.
Due to its high efficiency, low energy consumption, ultra-fine refinement, small floor space, low capital investment and no pollution in the environment, it is widely used in the grinding of mineral materials in metallurgy, building materials, chemical industry, mining and other fields. Non-flammable and explosive minerals with Mohs hardness less than seven grades and a humidity below 6% is suitable such as gypsum, talc, calcite, limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, bauxite, iron oxide red, iron ore, etc.
The main machine rotates the central shaft through the double belt combined transmission mechanism. The upper end of the shaft is connected with the plum blossom frame, and the grinding roller and the plum blossom frame are assembled to form a dynamic grinding system, and a swing fulcrum is formed. When the plum blossom frame rotates, the grinding roller presses the peripheral grinding ring to form a complete crushing combination, and the grinding roller rotates around the grinding ring while being rotated by the friction force. With the rigorous blade system, located in front of the grinding roller, during the operation, the material is thrown up and fed into the grinding ring to form a pulverized material layer. The material layer is crushed by the extrusion and friction generated by the rotation of the grinding roller. In order to achieve the purpose of grinding.
Non-flammable and explosive ore with a Mohs hardness of 6 or less and a humidity below 6%, such as calcium carbonate, graphite, bentonite, wollastonite, coal powder, water slag, fly ash, alumina, zircon sand , quartz sand, gypsum, talc, calcite, limestone, marble, barite, dolomite, granite, kaolin, bauxite, iron oxide red, iron ore, power plant environmental protection (desulfurization denitration).
