Kenya Limestone powder making line

Kenya Limestone powder making line, you contact with us for flowchart and price online.

  • Material : limestone
  • Output size : 225 mesh
  • Capacity : 8-10 t/h
  • Equipment : MTW138

Large pieces of limestone crushed by the crusher to enter the fineness of the material into the mill, grinding the material by the classifier powder classification, with the fineness of the powder flow through the pipe into the dust collector for separation and collection , then sent by the delivery device to the finished silo.

Natural shell powder grinding mill

Shell powder size is about 80-1000 mesh, which is use the grinding mill grind the natural shell. Shells natural raw materials are oyster shells , Hawaii shells, pearl shells. Natural shell powder can be used primarily as animal feed and high-grade green decorative paints , the other can be used for food sources of calcium additives, cosmetics, jewelry processing , desiccant, etc.

Shell powder mill according to the type of the shell is divided into the oyster shell powder grinding machine, Hawaii shell flour mill, pearl shell powder machine, etc. According to the working principle of type of mill and the fineness of finished product, can be divided into:

MW high pressure suspension Raymond mill: processing fineness between 15-200 mesh;
MW Ultrafine medium speed mill: processing fineness between 200-3000 mesh.
Shell grinding mill not only can processing of various shells, they can also processing of medium and low hardness , Mohs hardness of ≤ 7 levels of shells and other 100 kinds of materials , fine product size be adjusted between 15-3000 mesh, yield up to 0.5-12 tons per hour.

Colombia Limestone Raymond Mill Plant

Colombia Limestone Raymond Mill Plant

  • Material: Limestone
  • Final product: 500Mesh
  • Equipment: Vibrating feeder + Impact crusher + vibrating screen+ Raymond Mill

 processing crusher & milling machine

Case Background:

Limestone is calcareous sedimentary rocks formed at the bottom of lakes and seas with the accumulation of shells, bones and other calcium rich goods. It can be used in various industries, such as Cement Production, Wall cladding, Refining Metals and so on.

One of our customers from Colombia needs to grind Limestone into 500Mesh.We recommended Raymond Mill and it is running very well.

Limestone Production Line: Vibrating feeder + Impact crusher + vibrating screen+ Raymond Mill

In order to meet the feeding size of Raymond Mill, large limestone raw material should be crushed first. We recommended Impact Crusher. The crushed limestone will be sent by a belt conveyer then to vibrating screen and becoming final products or to grinding mill to fine grind. Limestone of sufficient quality or size for current demand is stocked on-site for further using.

Indonesian Cement Producer & Equipment

Indonesian cement producer PT Semen Padang signed a total of 40 million euros (300 million Danish kroner) contracts, cooperative project of a 8000t / d production line, the order includes a main part of the production line: raw mill, coal mill , preheater, kiln, furnace clinker cooler, silo equipment and a complete control system for the entire plant.

It is reported, which is the sixth production line production line of PT Semen Padang. PT Semen Padang as Indonesia’s largest cement producer, under Semen Indonesia Group, with an annual output of nearly 30 million tons of cement, located Indarung, from Indonesia’s West Sumatra city of Padang far. The order is expected to produce benefits will continue until the end of 2015.

Cement Crusher and Mill Plant

For cement plant, there always use complete processing line, the equipment list including cement jaw crusher, cement clinker crusher, cement vertical mill or ball mill, etc. If customer need these cement crusher mill equipment, can contact with us for more details, we can supply global service for whole cement processing line.

kaolin specialized ultrafine powder mill

According to high fineness requirements of Kaolin for paper industry, Kefid developed a new type fine and superfine powder processing equipment-MW ultrafind powder mill which combined with Sweden advanced milling technology. The machine uses continuous extension of grind. It has the features of grinding material for several cycles,the finished material with finer granularity (adjustable between 425-3250 mesh) and higher milling efficiency(single capacity 0.6-8t/h).
kaolin specialized ultrafine powder mill
MW ultrafine powder mill is mainly applied to the grinding process of low harness ore that Mohs hardness is below 6 such as kaolin, bentonite, calcite, limestone, calcium carbonate, talc, barite, fluorite, pumice, pyrophyllite, gypsum, graphite, titanium dioxide, etc. The effect is significant in the field of fine and superfine powder processing.It is the best selection of refined kaolin processing equipment.

MW 80 super fine mill in Thailand

MW 80 super fine mill Case Background:

Limestone is one kind of common stone in nature world. The primary uses of limestone and lime are in the construction industry and cement making. They are also used in the chemical and metallurgical industries.

One of our customers from Thailand was looking for solution for limestone milling. He required the fineness to be 700 mesh. We recommended MW80 super fine mill. And our engineers made a complete production line for his project as well.

HGM80 super fine mill in Thailand

Configured Equipment: Vibrating Feeder + Jaw Crusher + vibrating screen+ MW80 Super fine mill

The whole grinding mill line include Jaw Crusher, Bucket Elevator, Mill Deceleration Machine, Vibrating Feeder, Main Frame, Blower, Powder Concentrator, Powder Collecting System, Piping Device, and Bag Deduster.

Raw limestone material has been crushed by jaw crusher to suitable size to meet the feeding size of the mill. Then the crushed limestone will be sent to the mill for grinding. When the product is completed, it will be packaged.

Bauxite processing crusher & milling machine

Bauxite is referred to industrially utilized mineral ore which mainly composed of gibbsite,boehmite or diaspore. Its applications include metal and nonmetal.In the field of metal,bauxite is the best material for the production of aluminum which is the most important application areas.It accounts for over 90% of the world’s bauxite production;In non-metallic aspects, bauxite is mainly used as raw materials of refractory,abrasive materials, chemical products and high alumina cement.Bauxite processing crusher & milling machine
In the development and utilization of bauxite resources,crushing and milling equipment is indispensable. Crusher can crush chunks of bauxite ore to less than 30mm of small particles and then transport it to the mill for fine grinding and processing, sub-elect desired fineness, finally used in various production of industrial department.
These equipment have passed the ISO2001: 2008 quality system certification and won several national patents and scientific and technological progress awards.They are widely used in bauxite,calcium carbonate, limestone, calcite,  barite, talc, dolomite, kaolin, bentonite, gypsum and other minerals in the rock crushing grinding process.The effect is significant.
