( 1 ) Benzothiazole thiol (mercaptobenzothiazole, MBT ). The structural formula is: It is a yellow powder, insoluble in water, soluble in alcohol, sodium hydroxide or sodium carbonate solution. Its sodium salt is called Capnex and is soluble in water. Imidazole thiol is a white solid powder, hardly soluble in water, benzene and ether, and easily soluble in hot alkali (such as sodium hydroxide, sodium sulfide, etc.) and hot acetic acid. Used for flotation of copper oxide ore (mainly copper silicate and copper carbonate) and refractory copper oxide ore.
Introduction of Screw Conveyor
Screw conveyors, also known as auger conveyor,Spiral Conveyor, are made for simple conveying duties applications. The real strength of our company, however, is our ability to produce individually designed units that include features to overcome awkward installations, materials that are difficult to handle, or include performance or process functions beyond simple conveying. Some requirements may be concerned with aspects of hygiene, others with bulk solids that have poor or delicate conveying properties.
Screw conveyor is divided in two types rigid screw conveyor and shaftless screw conveyor.
Rigid screw conveyor is suitable for non-sticky powder and small particle material such as cement, fly ash, lime, flour, starch, food additive etc.
Shaftless screw conveyor is suitable for sticky and easy winding materials such as sludge, biomass.
Features of screw conveyor
*Tube type and U shape type available
*It can be designed inclined conveying,horizontal conveying and vertical conveying.
*Widely used for all kinds of powder,particles,small block and loose material.
*not suitable for conveying perishable material,high viscosity,less pressure resistant material.
*not suitable for agglomerate or high temperature material.
*not suitable for great corrosive special material and fragile material.
Warranty
Our machines have an automatic 12 months guarantee against faulty material and workmanship valid from the date of dispatch in China or date of arrival at foreign border.
If any problem of the machine under instruction within one year,we are responsible for replacement incuding delivery fee and maintenance.
Lifelong service is offered with cost charge after one year.

Benzthiazole thiol used in the flotation of zinc mineral chabazite, without pre-vulcanization, a xanthate results obtained with sodium sulfide results similar. Collector of lead oxide ore on strong. Sulfide ore flotation, galena collector of the strongest, sphalerite collector capacity is poor, the weakest of brass ore.
When the amount of benzothiazole thiol is high, it often causes the quality of concentrate to decrease. In practice, it is used in combination with xanthate or black medicine.
( 2 ) Benzothiazole thiol ( N -phenyl- 2- mercaptobenzimidazole). The structural formula is:
