There are several factors that will affect the operation of the gravity belt thickener, including: amount of conditioning chemicals used on the sludge. Too much polymer can bind the belt, clogging the belt pores and causing a washout. belt speed. The ideal belt speed is the slowest speed that can be maintained without washing out the belt.
Another important design parameter is the total height of the thickener, which consists of the raking, supernatant, and sludge zones. DWA-M 381E recommends a minimum height of 0.3 m for the raking zone and about 1.0 m for the supernatant zone.The depth of the sludge zone is most important, as it defines solids retention time.
3. High-Efficiency Thickener. In addition to the inclined plate installed in the thickener, the high-efficiency thickener has a special flocculant adding mechanism. The diameter of the thickener can be reduced to 1 / 3-1 / 2 of that of the common thickener, and the floor area is only 1 / 9-1 / 4 of that of the common thickener.

To start with, it works on the principle of Gravity sedimentation and the most common construction of a thickener would be of iron or steel. The continuous thickener consists of a cylindrical tank.
The thickener was applied at various concentrations (0, 4, 8, or 12 g/l) in the pretreatment bath to determine the effect of cationization on the optimal level of thickener. The concentrations of soda ash and urea in the pre-treatment were 40 and 100 g/l respectively.The fabrics, untreated cotton and cotton cationized with 100 g/l reactant, …
The belt conveyor design guide offers a comprehensive manual on power demands, belt curves, transitions, and industry standards for effective belt conveyor design.
Conveyors are cost-effective. Whether you are renting or buying a conveyor for your construction and build project, they reduce labour and operating time, offering you a materials movement solution exactly when you need it and because conveyors use electricity they potentially reduce running costs. Lastly, conveyors are robust, durable …
A variation is the tray thickener where trays or compartments are placed one on top of the other. Each tray acts as a thickener and the assembly operates in parallel with a common pier or shaft where the rakes are fixed. Clarification takes place in series operation, that is, the thickener underflow from the top compartment serves as feed to …

WEBOperation at temperatures below –15ºF involves problems in addition to horsepower considerations. Consult conveyor manufacturer for advice on special belting, greasing, …
It delivers ease and dependability. The center-pivot steering system reduces belt stretching, providing longer and more consistent performance. The machine also incorporates 11 rows of plows for increased throughput and thickening. There is even a pneumatic plow lift, for easy operation and cleanup.
The Clarence Sands wash plant is made up of a H30 Feeder, a 20x8 2 Deck Rinsing Screener, two FM 200C Sand Recovery Units, a Flocculant Dosing Unit, a Rake Thickener Tank and a number of stacking conveyors. The large through-put and stockpile capacity resulted in the installation of two 26-metre radial stockpiling conveyors.
The thickener area is also required for this calculation. Guess the thickener area for the first iteration. Several iterations of area may be required to achieve a practical thickener size and pumping rate. For a …
The construction of gravity thickeners is designed to withstand the corrosive nature of wastewater and the mechanical stresses of continuous operation. Stainless steel or coated carbon steel are often used for structural components to provide the necessary durability. ... Additionally, gravity thickener operations must maintain documentation to ...
operation. For large treatment plants, the use of variable speed controls should be investigated. 3. SLUDGE THICKENING. Thickening is provided to reduce the volume of sludge. Two basic types of thickeners work by gravity or flotation and use either continuous or batch processes. Gravity thickeners are essentially settling tanks with or without
Drum Sludge Thickener Panels. JWC's Monster Drum Thickener utilizes woven wire mesh for the construction of the sludge thickener screening panels. The woven wire mesh panel construction allows for capture rates in excess of 98% which is one of the highest available for sludge dewatering equipment.

Belt conveyors are essential systems in today's industry. The proper operation of the conveyor belt can be decisive in the efficiency of the entire production chain and the logistics of a warehouse. Although operation principle is the same for all of them, brackets are a very versatile system.
If, for some reason, the thickener's settling rate is too slow, as in the case of the grind being so fine or you are dealing with clay rich ore and now the concentrate stays in suspension. The thickener could be "sliming" and will produce a dirty overflow combined with a low density underflow. If this is ... Thickener Operating pH …
