Technical and technological features of company TTD developments and their impact on the final indicators of gold ore processing
The article presents some technical and technological features of the innovative developments of company TTD and an example of their practical use for the enrichment of gold-bearing ores.
Technology of enrichment of dump tails of various genesis
The article presents a technology for processing the tailings of factories, which, with some improvements, can be used to process raw materials from other man-made facilities, as well as primary placer gold deposits.
The presented equipment is a creative development of the TTD company and is currently unattainable by traditional technologies.
On speeding up the process of preparing geological samples for analysis
The article considers a new technical and technological complex for processing core samples and mining samples based on a planetary mill, which provides high productivity and a significant reduction in the time of field assessment.
Semi-self-grinding mills are becoming obsolete
More than one generation of graduates of specialized institutes has grown up who are unaware of the existence of mills operating in full self-grinding mode.
No one is deterred by the fact that semi-self-grinding increases energy consumption, lining consumption, and also requires reducing the size of the feedstock.
TTD LLC has been searching for technical and technological techniques for a long time to get rid of critical size when operating mills in full self-grinding mode.
The parameters of the discharge grid are a tool for increasing the efficiency of ore preparation
Back in the 1970s, the authors found that with certain geometric parameters of the cells, productivity does not depend much on the living cross-sectional area, but the sieve composition of the mill discharge changes significantly.
In the patent and specialized literature, little attention has been paid to the effect of discharge grate parameters on self-grinding parameters, whereas, in our opinion, its role is very significant not only in the processing of kimberlites. The following facts are a convincing illustration of this.
A self-grinding mill that was ahead of its time
Even after 130 years of mill operation, unexplored questions remain, to which engineering solutions have been proposed, in the opinion of the authors, radically changing the idea of equipment design and the role of elements such as lining and grating.
Talks about replacing imported machinery and technology have been going on for many years. This article presents specific, implemented developments to replace self-grinding equipment from Western manufacturers.
SAG grinding mills
For many years, there have been discussions about replacing imported equipment and technologies, but very often these discussions remain just words. However, there are real alternatives to Western-made mills, and they are being offered by the specialists of company TTD including already implemented and working solutions.
The planetary mills are over 130 years old. What do we know about them?
About 130 years ago, a guy from North America, looking at bulky ball mills, figured out why not combine several ball mills, distribute them in a circle and make them rotate around a common axis and around their own axes at the same time.
That’s how the first patent was born. Since the movement of ball mills resembled the movement of planets around the sun, these mills began to be called planetary, and later someone began to add the word «centrifugal».
Disintegration of hard-to-wash sands with highly plastic clay
The commissioning of deposits with a high clay content (30-98%) will obviously increase, provided effective disintegrators are available.
What is the difference between our drum disintegrator (scrubber) from well-known scrubbers? First of all, the ratio of diameter to length.
We present to our dear readers two types of disintegrators (scrubbers) developed and manufactured by TTD, one of the drum type, the other of the centrifugal type.
