a deep cone, or deep bed, thickener produces paste. both high density and deep cone thickeners depend on retention time rather than area. yield stress is the dividing line between paste and thickened tailings, and deep cone thickeners produce a yield stress of 120 to 150 pascals pa and greater.
thickeners are widely used in hydrometallurgical, concentrating plants, chemical plants and other production sites where solid-liquid enrichment and separation are required. the diameter is 3 to 100 m and the depth is 2 to 4 m. jxsc provides another type of drum high-efficiency thickener, and other dewatering machines you may interest in. advantages:
thus, paste thickeners are commonly run at a higher rise rate than a conventional or high-rate thickener either using more flocculant or accepting more solids in the overflow , giving the appearance of having a higher capacity.
004 outotec thickening technologies complete service testing the bench or pilot scale testing can be conducted either on site or in one of outotec laboratories around the world. process guarantees are given based on test results. selection test results and outotecs extensive experience are used to select the appropriate size and type of thickener
outotec paste thickener. the outotec paste thickener has a high sidewall and steep floor slope and reacts relatively quickly to changing process conditions. the system can utilize automation, with control based on consistent solids inventory to achieve the required underflow density. our paste thickener benefits from relatively stable feed conditions.
a circular thickener comprises a relatively shallow, open-top cylindrical tank with either a flat bottom or a bottom shaped in the form of an inverted cone see figures 1.2 and 1.3 . the feed mixture is gently and continuously introduced to the feedwell in which exists a pool of settling suspension along with any additional coagulant or flocculant.
so with that in mind, we wanted these snow cones to be extra special and what we found worked perfectly the snow cone maker and snow cone cups were right in the seasonal dishes area, near housewares. the snow cone maker was under $17 and the cups were under $3, so for right around $20 this little gem makes a fun treat.
site location and logistics costs may also impact the appropriate selection. mclanahan design tools assist customers with choosing the best outcome for each application. mclanahan thickeners can be used as stand-alone solutions or used in conjunction with other equipment, such as hydrocyclones, dewatering screens, pumps and filter presses.
a copper mine concentrator is limited by site area, so the equipment are almost products which coves small area. in the thickening process, effective deep cone thickener solved this problem perfectly.
the conventional thickener. the picture on the right shows a 6 meter diameter wooden tank 'dorr' thickener installed back in 1908 in the kennicott copper mill in mccarthy, alaska and in 2011 i had the thrilling opportunity to fly from chitina to mccarthy in a six seater plane to visit the abandoned mill.
the premise for using high-density thickeners. using our example from table 1, but substituting paste thickeners, we can change just the underflow assumption to 60% solids and dramatically impact recovery. as can be seen in table 4, a three-stage circuit with deep cone thickeners produces 97.6% recovery.

the thickener options for high tonnage application are either multiple deep cone thickeners or a single high density thickener. this plant target low-yield stress underflow would not require the higher yield stress and underflow solids produced by a deep cone type paste thickener. therefore two 45m-diameter westech hidensity thickeners are used.
how thickeners work. clean water rises to the top of the thickener and overflows a peripheral weir into a collection launder. once collected in the overflow launder, clean water exits through a single flanged outlet and can flow via gravity to a water storage tank or clean water pond for reuse.
deep cone thickeners are designed and constructed to give optimum performance and reliability in even the toughest applications. the deep cone provides a smaller foot print than a rake style thickener saving space on site. the thickened sludge underflow can reach solids content of over 50%.
snowie has found the perfect formula in this snowie sweet thickener to give your sugar free flavor the same type of texture and eatability as the real thing. they come in package sticks that have a powder inside, when it goes into water it makes the water thicker making it so when it goes on the shaved ice its clingy and slippery and makes it much sweeter and best of all sugar free
deep cone thickener. deep cone thickener is a new kind of thickening equipment, with the obvious advantage of large capacity , high underflow concentration and high automatic level. depth range of thickener: 5-15m. diameter range of thickener: 3-40m. capacity: 50-5000t/d
