raymond mill for superfine powder - ftm machinery

raymond mill for superfine powder - ftm machinery

Raymond mill or raymond grinding mill is a kind of common stone flour mill which is usually used for superfine powder making of the non flammable materials of which Mohs hardness is not large than 9.3 and water content is below 6% like calcite.

Raymond grinding machine is also called Raymond mill for short. It looks like an upright steel container from the shape, has inlet and outlet, and a feed port is set in the middle. According to different raw materials, fineness and capacity, FTM Machinery has three series of corresponding grinding mills: high-pressure mill, high-strength mill, and Raymond mill.

Raymond mill is mainly used for barite, calcite, potassium feldspar, limestone, talc, white stone, gypsum, etc. The Mohs hardness of any raw material is no more than 9.3, and the humidity is less than 6%. The size of finished materials can be adjusted in the range of 40-400 mesh. A single Raymond mills processing capacity can reach to 60TPH.

Raymond grinding mill machine is widely used in the grinding of mineral products in metallurgy, building materials, chemical industry, mining and other fields. It is suitable for processing various non-flammable and explosive materials with Mohs hardness below 7 and humidity below 6%. Finished product fineness is between 613m and 44m, the combination of analyzer and fan can meet the requirements of different users.1.Strong system and high screening rate2.Smooth transmission and high wear resistance3.Easy to control and easy to maintain

Raymond mill consists of main engine, analyzer, fan, finished cyclone, fine powder cyclone and duct. And the main engine is made up with rack, inlet volute, blade, grinding roller, grinding ring, casing. Generally, users will also choose a jaw crusher, bucket elevator, electromagnetic vibrating feeder, etc. as auxiliary equipment according to their own needs.

Raymond mill grinds the material by the mutual extrusion of roller and grinding ring. When the Raymond mill is working, the transmission drives the roller shaft to make a rapid rotary motion. The action of the grinding roller is a fixed grinding ring. The grinding roller acts on the fixed grinding ring. When the material is fed into the body through the feeder, a blade installed at the front of roller continuously feed the material into grinding zone between the grinding roller and grinding ring.

Since the grinding roller is revolving along the axis, it continuously rolls outward and gradually approaches the grinding ring, and finally presses against the grinding ring. Meanwhile, the material mixed between the grinding roller and grinding ring is crushed by the pressing action, thus completing the entire grinding work.

After the material is ground, the fan blows up the powder, and sorts it through an analyzer placed above the grinding chamber. If the material is too thick, it will fall into the grinding chamber and re-grinds, while the fineness that meets the requirements will enter the cyclone collector with the wind flow. After collection, it is discharged through the powder outlet, which is the finished product. The wind flow is returned to the fan by the return air duct at the upper of a large cyclone collector.

The winding path is cyclic and flows under negative pressure. The wind of the circulating air path is discharged through the exhaust pipe between the fan and the main engine, and then enters the small cyclone collector for purification treatment.

2.Raymond mill uses the a sealed gearbox and pulley to drive the device. The vulnerable and easy-to-wear parts are made of high-quality steel, which prolongs its service life and makes the rotation more stable and reliable.

3.The whole airflow system is closed and circulates under the negative pressure state. The increased air volume enters the small cyclone collector through the exhaust pipe in the middle of the host, and is removed after purification treatment, which meets environmental protection requirements.

4.The Raymond mill produced by FTM company adopts PLC electrical automation control, which is convenient to operate, reduces maintenance costs, and achieve a good production environment with low noise and less pollution.

5.Milling fineness can be adjusted freely between 80-800 mesh, so Raymond mills applicability is more flexible and extensive. FTM Machinerys Raymond Mill is the best choice for non-metallic ore grinding.

Stainless steel is a name of high alloy steel used mainly for its anti-corrosion properties. The main characteristic of the stainless steel family is that they all contain a minimum of 10.5 percent of chromium.

The percentage of carbon in steel affects the hardness, strength of elasticity and ductility of steel. Low-carbon steel, also known as mild steel, has similar properties to iron but it is softer and easy to form.

Hot-dip galvanized steel combines utility with beauty. It consists of tin, chrome, zinc or paint, which are the extra finish applied to the natural steel surface.

Aluminum and most of its alloys are very resistant against various forms of corrosion. This property makes aluminum popular among construction, marine engineering and the transportation industry.

Steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe, which are used in a variety of places.

Steel bars have a wide range of uses and diverse applications in the industrial sector. A wide variety of alloy composition types can comprise steel making it a very versatile material for use in producing carbon steel bars and stainless steel bars.

Wire rod is a hot rolled steel product classified by its shape. It can be a carbon steel or stainless steel product. Wire rods are used as the material for fasteners, springs, bearings, wire ropes and wire meshes.

Steel has many different properties depending on the other elements that compose it. Steel is a material which is the most widely used in industrial applications, as well as the most recycled metal material on earth.

Sulfur is one of the most important agricultural and industrial raw materials and is considered a strategic product sulfur is an odourless, tasteless and polyvalent nonmetal which is mostly in the form of yellow crystals and is obtained from sulphide and sulphate. Sulphur occurs naturally in the environment and is the thirteenth most abundant element in the earths crust. It can be mined in its elemental form, although this method has declined over the last decade to less than 2% of world production. Today most elemental sulphur is obtained as a co-product recovered from oil and gas production in sweetening process.

Sulphur is the primary source in the production of sulphuric acid, the worlds most widely used chemical. Sulphuric acid is an essential intermediate in many processes in the chemical and manufacturing industries. Sulphuric acid also is used by the fertilizer industry to manufacture primarily phosphates, nitrogen, potassium, and sulphate fertilizers.

Sulfur reacts directly with methane to give carbon disulfide, used to manufacture cellophane and rayon. One of the direct uses of sulfur is in vulcanization of rubber, where polysulfide chains crosslink organic polymers. Large quantities of sulfites are used to bleach paper and to preserve dried fruit. Many surfactants and detergents (e.g. sodium lauryl sulfate) are sulfate derivatives. Calcium sulfate, gypsum, is mined on the scale of 100 million tonnes each year for use in Portland cement and fertilizers. Sulphur is increasingly used as a component of fertilizers.Sulfur can be used in agriculture and various industries such as plastics and many synthetic products, paper, paint, etc.

The increasing demand from the fertilizer manufacturing sector, coupled with increasing usage of sulfur for vulcanization of rubber are the main factors driving the growth of the global sulfur industry. Moreover, owing to the fall of crude prices, refineries across the globe are engaging in capacity expansion and other brownfield activities, leading to higher demand for sulfur. The demand for sulfur is also anticipated to be driven by the increasing usage of elemental sulfur as a major ingredient in the vulcanization process implemented to manufacture rubber. However, the enactment of stringent environmental regulations restricting the usage of sulfur and the high costs associated with its mining, are the key factors hindering the sulfur market growth.

The global market is segmented based on end-user applications, including agrochemicals, chemical processing, metal manufacturing, petroleum refining, and others. In 2016, the agrochemical industry occupied the largest share in terms of sulfur consumption. It is expected that the healthy growth of the phosphate fertilizer market will drive the global sulfur market over the forecast year.

Geographically, the market has been segmented into North America, South America, Europe, Asia-Pacific, and Middle East & Africa. Asia-Pacific represents the largest market in terms of consumption and production of sulfur. In the region, China is expected to be one of the largest producers of sulfur and sulfuric acid. Currently, the country imports more than a third of the global sulfur` trade. This group is able to provide sulfur with the highest quality in two kinds of granule and lump.
