Sand washing machine is a kind of high-efficient machine, which is produced by fote according to the actual situations of sand industry around the world.
Flotation cell, also named as flotation machine, is of great importance for ore separation. The flotation effect can be influenced by the factors of ore particles, ore pulp or drug.
Jaw crusher machine, also named jaw crusher for short, is the earliest crusher.
The coal ash dryer made by our company, as the Chinese leading raw coal drying machine supplier, is specialized in drying the coal ash and then makes new use of it.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
Mobile crusher is the machine that has crusher, feeder, feeding hopper, belt, driving and controlling systems on mobile chassis.
VSI sand maker, also called VSI crusher, is the major machine for sand making plant. During the crushing process of sand making machine, raw materials hit each other and not hit any metal parts.
Briquette machine is also called briquetting press machine, briquetting machine or pressure ball machine.
In a resininpulp process for the recovery of gold cyanide from a very dilute solution it is desirable that the resin should exhibit the ability to load gold at the natural pH of the leach liquor and be stripped by an aqueous alkali The present work describes the results of gold cyanide adsorption by new ionexchange hollow fibers prepared by the amination of sulfochlorinated polyethyleneRead More
