The Mica World Resources

crusher in UAE crushers
India is the leading producer of muscovite mica followed by Brazil. Other producing countries are the USA, Tanzania, Rhodesia and Argentina. The USA generally produces scrap mica. The leading producers of phlogopite mica are Malagasy Republic and Tanzania whose average annual productions are 1,000 tonnes and 300 tonnes respectively. Small production of phologopite is reported from Canada, Tanzania and India.
The Mica Industrial Applications
Sheet mica is used in a number of electrical and electronic appliances in different shapes and sizes. As an insulating material it is used in equipment like condensers, transformers, sheostats, radio and electronic tubes and radar circuits. It is used in the form of washers, discs, tubes and plates.
Nowadays mica is finding increasing use in equipment that encounters very high temperatures like rockets, missiles and jet engine ignition system. Phlogopite is used in spark plugs. Sheet mica, however, is not always available in required size as demanded by the industry.
Great progress has been achieved in making built-up mica called micanite. Mica films are placed with alternate layers of binding materials like shellac, alkyl, or silicon resin and then pressed and baked. Micanite is in common use now. It is convenient to cut or punch micanite according to requirements.
In the electronic-field, natural mica is mainly used in the manufacture of capacitors such as bridge-spacers in electronic valves and as panel-board where heat-resistance and low-loss peoperties at high frequencies are required. In such delicate equipment, mica of thinness varying from 0.015 inch and below are used. The mica of thickness in the range of 0.007" to 0.015" is used in bridge-spacers. Even thinner films, between 0.004" to 0.006", are used as backing plates for capacitors and further thinner films in the range of 0.0007" to 0.002" as dielectric. The splittings of such fine thickness are made with the help of pin and knife only. So you can find it the mica needs to be crushed.
Waste or scrap mica is used invariably in the form of ground mica. The uses of ground mica depend largely upon its appearance and lubricating properties. Both of these characteristics are affected by the methods of grinding as well as teh purity and nature of the scrap.
Before you use the mica, you need to crush or mill it. SBM supply the mica crusher and mica grinding mill: mica jaw crusher in doubai, mica impact crusher, mica cone crusher, vsi mica crusher, mobile mica crusher, trapezium mica grinding mill, mica ultrafine grinding mill, mica ball mill grinder etc.

The Greens are declaring it will oppose the conversion of coal into liquid in the Hunter Valley.

This follows questions to the NSW parliament regarding investigations into the Denman-Scone area from Greens senator Lee Rhiannon.

After Rhiannon uncovered a report from 1981 that outlined the area had suitable feedstock for coal liquefaction, she voiced her concern over what outcomes it may have.

"Where we're worried, it can just further lock us into a dependence on coal power. That's just bad news in terms of emissions, in terms of local environmental impact," she said.

The Greens will now push this issue into the Federal arena.

"We will continue to track this and actually look at it federally, because the study cost $3.6-million with both the Federal and State Governments paying.”

Concrete Recycling system

Concrete Recycling system Introduction
At present，most of concrete mixing plants connot provide good residual concrete recovery system in our country. The majority adopt the sedimentation pond to complete the separation of liquid and solid. Although this method can realize part of sewage recycling, it cannot solve the recycling problem of sand stone and cement in the concrete thoroughly.During the production concrete, some scrap concrete may be generated. Once these scrap concrete aoagulates, it will pollute environment. According to statistics, scrap concrete compositon accounts for 1%-2.5% of the total concrete production, which brings massive economic loss and the environmental pollution. In order to meet the market development and demand, combined with our long years experience in research and manufacturing the aggregate processing equipment, we have developed a new generation scrap concrete recycling system, CRP series concrete cycling plants,achieves truly zero emission.

To meet customer’s specific requirement, we can also add other equipments such as cone crusher, dust catcher on the production line.

Process of Stone Production Line:

Vibrating feeder feeds the big materials into jaw crusher evenly and gradually through a hopper for primary crushing. After the first crush, the materials will be transferred to impact crusher by belt conveyor for the secondary crush. Then the crushed materials will be transferred to vibrating screen for separating. After separating, the part materials will be returned to impact crusher, while the others that can meet standard will be transferred away as final products, thus forming a closed circuit. We can equip dust catcher system to protect environment. In addition, the size of final products can be also combined and graded according to customer’s specific requirement.

Sand production line

Sand production line includes vibrating feeder, jaw crusher, impact crusher, vibrating screen , belt conveyor and centrally electric controlling system, etc. The designed capacity is from 50t/h to 500t/h. To meet customer’s specific requirement, we can also add other equipments such as cone crusher, dust catcher on the production line.

Process of Sand Production Line:

The stone material is sent regularly by the vibrating feeder to the primary jaw crusher , the crushed material is sent to the secondary jaw crusher to be crushed again. The crushed material is sent by belt conveyor to vibrating screen to be separated. The material, whose size is suitable for the feed size of the sand making machine, can be sent to the sand making machine. The unsuitable material should be sent back to the secondary jaw crusher to be crushed again. The crushed material from the sand making machine is sent back to the vibrating screen to be separated. The suitable separated sand, which is the final product, should be sent to the sand washing machine to be cleaned, and then sent by the belt conveyor. The unsuitable separated sand should be sent back to the sand making machine to be crushed again. The producing line forms two closed cycles. The producing line can be changed according to the customers’ requests.

Vibrating screen

Vibrating screen  is the circular vibrating type; we called it circular vibrating screen also. SBM’s vibrating screen earns this name by reason of its approximately circular movement. Vibrating screen is of multilayer and high efficient. The eccentric shaft vibration exciter and partial block help to adjust amplitude. This kind of vibrating screen is of long streamline, clear screening for different specifications.

Vibrating Screen Application

Vibrating screens are widely used for grading and screening materials in such fields as chemical industry, minerals, quarry, building materials, water conservancy and hydropower, transportation, smelting and so on. Vibrating screens are efficient screening machines for the classification of bulk material such as coal, minerals, coke etc. There are 40 specifications for this series vibrating screen, of which the heavy duty type of vibrating screens are for the classification of large size materials, while the light duty type of vibrating screens are for the middle and small size materials.

Vibrating Screen Working Principle

Vibrating screens work on circular motion. The vibrating screens are mainly used in coal dressing, metallurgy, mine, power station, water conservancy project, building industry, light industry and chemical industry etc They are efficient screening machines for the classification of bulk material such as coal, minerals, coke etc There are 40 specifications for YK Series, of which the heavy duty type is for the classification of large size materials, while the Light duty type is for the middle and small size materials.
Vibrating Screen moves round .It has multi-layers and is of high efficiency. The eccentric shaft vibration exciter and partial block help to adjust amplitude. The material drops down along the long line.

Belt Conveyor System

Belt conveyor systems is consisting of a metal frame with rollers at either end of a flat metal bed. The belt is looped around each of the rollers and when one of the rollers is powered (by an electrical motor) the belting slides across the solid metal frame bed, moving the product. In heavy use applications the beds which the belting is pulled over are replaced with rollers. The rollers allow weight to be conveyed as they reduce the amount of friction generated from the heavier loading on the belting. Belt conveyors can now be manufactured with curved sections which use tapered rollers and curved belting to convey products around a corner.

Belt Conveyor Main Features and Benefits

1. stable and longer convey with no relative movement.
2. noise reduction.
3. simple structure, easy maintenance, energy-saving and low cost.

ball milling

As a piece of mineral processing equipment, a ball mill  is widely used in beneficiation, building material and chemical industries. Ball mill is suitable for dry-type ore grinding and wet-type ore grinding. According to different discharging methods, ball mills fall into grate ball mill and overflow ball mill.

Working Principle:
Our ball mill is of horizontal, cylindrical and tubular structure. It comes with two cabins and is a grate ball mill. The materials are evenly fed through the charging device to first warehouse where there are step scales boards, corrugated scale boards and different specifications of steel balls. When the cylinder rotates, the centrifugal force produced causes the steel balls to impact and grind the materials in the ball mill. The materials are then lead to the second cabin for further milling until they turn into powders and are discharged from the outlet.

Ways of Improving Productivity:
In addition to manufacturing ball mill, we also carry our research on improving its productivity. Generally speaking, the productivity of ball mil can be improved by
1. adding fine crusher before the ball mill.
2. improving grinding system to achieve better grinding efficiency.
3. adding powder concentrator..

Range of Applications:
Ball mill is a mineral processing machine for milling the materials into powders after they are crushed. It is widely applied to the production of cements, silicate products, building materials, fireproof materials, fertilizers, glass, ceramics as well as nonferrous and ferrous metal processing industries. It could carry out dry and wet millings on different materials.

Structural Features:
This ball mill is made up of feeding part, discharging part, gyre part, transmission part (transmission part includes reducer, small transmission gear, generator and electrical control) and so on. It enjoys features like good abrasive resistance, stable and reliable operation.
Inner structure of the ball mill is made up of lining plate, grate plate, diaphragm, feeding and discharging devices. The lining plate is used to protect the tank body in order to avoid the impact and abrasion from materials. Different types of lining plates can be used to adjust the movement of materials. Our lining plates are provided by Luoyang anti-abrasion academe and have a large share in the global market with their fine design.

Usage in Mineral Processing:
Minerals are firstly crushed by jaw crusher until they are crushed to suitable sizes. They are then equally fed to a ball mill with a hoister and a feeder. Later, they are further crushed and milled in the ball mill. Finally, fine minerals are classified by a spiral classifier with the principle that solid particles sink at different speeds in liquid.

Kaolin Crusher and kaolin stone Mill

Rocks that are rich in kaolinite are known as kaolin, which is a fine, pure-white clay (hydrated aluminum silicate). Some of kaolin is hard rock, some is soft clay. Kaolin rock must be crushed and fine grinded to get kaolinite. SBM can supply kaolin crusher and kaolin Grinding mill  for you.

Kaolinite is one of the most common minerals. Kaolinite is used in ceramics, medicine, coated paper, as a food additive, in toothpaste, as a light diffusing material in white incandescent light bulbs, and in cosmetics. It is generally the main component in porcelain.

Rocks that are rich in kaolinite are known as kaolin, which is a fine, pure-white clay (hydrated aluminum silicate). Some of kaolin is hard rock, some is soft clay.

Hard kaolin rock must be crushed and fine grinded to get kaolinite. The crushing process can be constructed by Jaw crusher, vibrating feeder, vibrating screen, and belt conveyor. Of coarse, Jaw crusher  can be replaced by Cone crusher  or Impact crusher , which depends on requirement to the size, shape of the stones and design plan of kaolin production line. The grinding process includes ball mill, hopper, classifier, elevator and so on. Ball mill can be replaced by ultrafine mill, coarse powder mill, raymond mill or MTW trapezium mill.
