Abstract

The present invention relates to tourmaline and its making method, and said method includes five steps of ore dressing, course powder processing, course powder purifying, extrafine grinding and packaging. The ultrafine powder grinder makes the powder body rotate and rese with tangential speed lither than 120 m./sec. against lining plate and collide with each other to form ultrafine powder with particle size smaller than 0.1-15 micro. The tourmaline is black hexgonal prism crystal and is pure solid silicate mineral containing boron, and may used in water purification under temp. of 0-700 deg.C.

Description

Tourmaline and manufacture method thereof

The present invention relates to nonmetallic ore powder and manufacture method thereof.

Current processing to tourmaline, can only adopt conventional equipment that it is carried out roughing, the processing fineness is about 300 orders, and can't handle its impurity composition, can not reach certain purity, impurity composition is too much, certainly will influence the tourmaline substantive characteristics, limit the popularity of its application, as the tourmaline particles potential difference, its particulate is healed little two extreme differences more greatly, common bulk is under specific temperature, the two poles of the earth potential difference is generally about 5.3V, and particulate is when 0.3 μ m is following, under specified pressure and temperature, its the two poles of the earth potential difference can reach 1,000,000 volts, therefore only make it be processed into ultrafine dust, just can make full use of its substantive characteristics, and can't realize super-fine processing at present.

The purpose of this invention is to provide a kind of purity height, the tourmaline of super-fine processing and manufacture method thereof.

The object of the present invention is achieved like this, and its manufacture method divided for five steps:

The first step: ore dressing: select to be fit to the big or small ore that the meal process equipment allows, block external diameter is less than 150mm; Choose metallics mixed in mining and transportation; Choose the too much ore of impurity.

Second step: meal processing: adopt the bicavate gyratory crusher under field conditions (factors), block external diameter 8～25mm size is arrived in ore reduction; Adopt the roller press type pulverizer,, be processed into granularity under field conditions (factors) at 10～150 purpose meal shapes with the ore of 8～25mm.

The 3rd step meal is purified: adopt the double plate magnetic separator, purify in the high-intensity magnetic field of natural temperature, reach 98% above purity.

The 4th step: ultra-fine grinding: adopt ultrafine crusher, be patent equipment, the patent No. is ZL97246396.8, patent name is a ultrafine crusher, the product that to be purified adds in the pulverizing chamber from charging aperture, material falls on the dumping of rotation at a high speed, throw to liner plate with the tangential velocity of per second more than 120 meters, produce fierce bump, material was pulverized in moment, simultaneously flown to hit to multi-direction high speed again by comminuting matter, produce the powder of the repeatedly high velocity impact between the material, the while makes powder begin the rotation rising and collides mutually under the effect of the eddy airstream of the generation of dumping of rotating at a high speed, friction is sheared and the finer autogenous grinding of formation.The powder that reaches the certain particle size requirement is collected and classification again by collector by outside the internal classification device discharge machine, and the powder that does not reach granularity returns pulverizing chamber by the internal classification device to be continued to pulverize, and is processed into the superfine powder of granularity less than 0.1～15 μ m.

The 5th step: packing:, carry out quantitative package on request with the superfine powder that processes.

Adopting the tourmaline of above-mentioned manufacture method processing is black irregular six prismatic crystal, is the solid silicate mineral matter of boracic,

Chemical composition: X.Y ₉B ₃S ₁₆O ₂₇(O.OH.F) ₄

Wherein: X represents among Ca, Na, K, the Mn one or more,

Y represents among Mg, Fe, Al, Cr, Mn, Ti, the Li one or more.

Advantage of the present invention is: tourmaline is the physical characteristic with suitable hardness, fracture mechanics and aerodynamics are adopted in its ultra-fine grinding, from the tens thousand of inferior frequency autogenous grindings of per second, broken ratio is big, the crush efficiency height, ultra-fine grinding operation continuously under closed state fully, pulverizing also reaches standard-required, finished product purity height, and power consumption is few, the finished product granularity can be selected, and dust pollution is little.Tourmaline has piezoelectricity gas and current collection gas characteristic, and temperature can be applicable to industries such as water purification, medicine, desalinization in 0～700 ℃ scope.

The present invention is described in detail below in conjunction with embodiment.

Embodiment 1

The tourmaline manufacture method divided for five steps:

The first step: ore dressing: select to be fit to the big or small ore that the meal process equipment allows, block external diameter is less than 150mm; Choose metallics mixed in mining and transportation; Choose the too much ore of impurity.

Second step: meal processing: adopt the bicavate gyratory crusher under field conditions (factors), block external diameter 8～25mm size is arrived in ore reduction; Adopt the roller press type pulverizer,, be processed into granularity under field conditions (factors) at 10～150 purpose meal shapes with the ore of 8～25mm.

The 3rd step meal is purified: adopt the double plate magnetic separator, purify in the high-intensity magnetic field of natural temperature, reach 98% above purity.

The 4th step: ultra-fine grinding: adopt ultrafine crusher, the product that to be purified adds in the pulverizing chamber from charging aperture, material falls on the dumping of rotation at a high speed, tangential velocity with 130 meters of per seconds is thrown to liner plate, the powder that reaches the certain particle size requirement is by outside the internal classification device discharge machine, collected and classification again by collector, the powder that does not reach granularity returns pulverizing chamber by the internal classification device to be continued to pulverize, and is processed into the superfine powder of granularity less than 0.5 μ m.

The 5th step: packing:, carry out quantitative package on request with the superfine powder that processes.

Adopting the tourmaline of above-mentioned manufacture method processing is black irregular six prismatic crystal, is the solid silicate mineral matter of boracic,

Chemical composition: X.Y ₉B ₃S ₁₆O ₂₇(O.OH.F) ₄
