Today, some small and old mines are still using the old-fashioned   thickener , whose enrichment effect is very poor. That because the design of early equipment is not perfect, such as lower tank ledge, internal overflow groove, overlapping scraper, etc. So, how to improve the efficiency of the old thickener? Here are several solutions from Xinhai. 1. Deepen the ledge of the settling tank The production capacity of settling tank has nothing to do with the height of ledge, which mainly depends on the settling velocity and settling area of the tank body. In fact, the solid particles of the concentrating tank are not settling freely in the static liquid. Their settling velocity is decreased with the increasing slurry concentration in the declining process. When the section reaches the critical speed, it is difficult to control the thickening effect if the ledge is too shallow. Therefore, increasing the height of tank body appropriately under the condition of controlling the d...

Sludge thickener  is the most widely used equipment in the mineral processing plant, in which every concentration and dewatering process need sludge thickeners. However, during the actual operation process, the failure rate of sludge thickener can reach 37%, so in order to reduce the failure rate of sludge thickener, daily maintenance is the key point. The daily maintenance of sludge thickener requires full-time staff to perform daily inspections, machine lubrication, regular maintenance. In addition, the maintenance personnel should be able to handle emergencies; all qualified maintenance personnel can ensure the sludge thickener works stably. 1. Sludge thickener Daily Inspection Daily inspection is an indispensable process for large-scale equipment. It is necessary for the on-the-job personnel to understand the structure, performance, specifications, names, and functions of various components. They are familiar with the entire process of equipment operation, to carry out ...

Sludge thickener can play a very important role in the process of sludge treatment. This paper will introduce the problem of flocculant when sludge thickener processes sludge. There are several ways to add flocculant to the pulp in the sludge thickener. Different methods mean different effects. The method of multi-add flocculant solution is to distribute polymer effectively, so as to shorten the mixing time between flocculant and slurry. The mixed systems are as follows: first, adopting flocculant solution sprayer or tank with flocculating solution nozzle and damper. Second, make a very short stirring before sending to sludge thickener. In this way, flocculant solution can disperse well in the slime water, but the standing time in the reaction area is not shorter than polymer absorption. Therefore, Flocculation group cannot be hindered in terms of formation and growth. Synthetic flocculant is the most common flocculant that used to treat coal industrial wastewater. This flocculant i...

Thickener is a new type of thickener and dewatering equipment which combines the filtrating characteristics of the mud layer. It is mainly used for the dewatering treatment of concentrates and tailings. Generally, the thickener is mainly composed of a concentrated pool, rake frame, transmission device, rake lifting device, feeding device, unloading device, and signal safety device. The main feature of the thickener is to add a certain amount of flocculant in the slurry, then the ore grain forms floccules, which speeds up its sedimentation rate, thus improving the thickening efficiency. Thickening is the last process in the whole mineral processing production line. For the wet products after flotation process often need the thickening operation to remove the extra water. Usually, the thickener manufacture sends the independent parts to the customers. So, the installation shall be carried out on the site and the installation sequence of the thickener shall be noticed carefully. Th...
