LM series vertical mill is the ideal substitute of the traditional grinding mills like raymond mills, high pressure suspension grinding mills, ball mills, etc. Nowadays, Shibang vertical grinding mills have been widely used in cement, power,metallurgy, chemical and nonmetalliferous ore industries. The LM series vertical mill is widely used to grind lumpy, granular and powdery material to the required size.
Raymond mill is also known as Raymond, Raymond machine. It is mainly for non-explosive mineral, chemical, construction and other industries more than 280 high fine powder processing kinds of materials with Mohs hardness is not greater than 9.3 and humidity below 6% like barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, active clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, etc.
F. S. Witherbee in his paper read before the American Iron and Steel Institute last October gave an estimate of 1,100,000,000 tons of crude magnetic ore above 30 per cent. Fe available for concentration in the Adirondack region alone, not including any titaniferous ores except the one deposit at Lake Sanford. He practically confined his estimate to the area of the iron-bearing gneisses which surround the central core of later eruptives, the anorthosites and gabbros, in which the titaniferous ores are found.
With the dry mills, the pulverized finished material is discharged, while the drum mill rotating, through the opening with an discharge grid that is fitted on instead of the lid. To collect the discharged material, the dry mills are provided with a dust hood. It encloses the drum mill and tapers to a funnel-shaped outlet.
It could realize multi-angle cylinder body grinding by special fixtures.
A Raymond Mill covers a small area, and can complete powder preparation efficiently and the fineness of the finished product is uniform and the screening rate can be as high as 99%;
As far as grinding mode is concerned, if the grinder has sufficient power and rigidity, creep-feed single pass grinding is recommended. Generally this mode of grinding produces the highest productivity, longest wheel life, and best workpiece finish. Conventional multi-pass grinding is also very effective for most tool and cutter grinding operations. The recommended wheel speeds during dry grinding is in the range of 3000 to 4500 SFPM (15 to 23 m/s). The higher wheel speeds may cause burning of the tool edges. In wet grinding, wheel speeds in the range of 5000 to 6500 SFPM (25 to 33 m/s) provide excellent results. In general, the higher speeds improve both wheel life and metal-removal rates. The traverse feed rate should be kept constant because of the cool, free-cutting characteristics of CBN grinding wheels. Whenever possible use the creep-feed, single-pass grinding mode. Use lower feed rates when grinding dry. Roughing cuts should be about 0.002 in. (0.05 mm) deep, while finish cuts are usually 0.005 to 0.001 in. (0.01 to 0.02 mm) deep. Spark-out passes are not necessary when using CBN wheels because, if the grinder is in good condition, whatever is set for the depth of cut is what is removed from the tool being ground.
Other capabilities include Drilling, Slitting, Boring, Grinding and Broaching.

The Diorit 2019 is available as a four or eight-roller mill in a total of nine different models. The Diorit MDDY-600/250 four-roller mill is now available in three different versions, offering the flexibility to choose between two and four milling passages. The standard version of the Diorit four-roller mill with a roller length of 600mm enables two milling passages.
The equipment adopts a new sealing structure design, and the grinding roller device can be filled with grease once in 300-500 hours. In addition, the replacement of the grinding ring does not require the removal of the grinding roller device, which makes maintenance more convenient.
The following is the old type wet pan mill, the steel plate is thinner.
The glaserite mother liquor is subjected to another crystallization process 610 in which glauber salt is precipitated as a product. The mother liquor from this process 610 is recycled to evaporator 601. The glaserite obtained in crystallizations 602, 603 and 605 is decomposed in decomposition process 607. This is followed by another crystallization 608 in which potassium sulfate crystals are deposited. These are treated in dryer 609 to form potassium sulfate product. The mother liquor from crystallization 608 is recycled to glaserite crystallizer 605.
