分砂罐

分砂罐 are typically used to classify s和 for most construction specifications by removing an excess of certain intermediate mesh sizes while retaining finer mesh sizes of s和. 分砂罐 are often used to classify multiple products from a single s和 feed.

菠菜网最稳定正规平台_最全菠菜网大全 S和 Manager™ 分类 Tanks are capable of making one or two products for most construction s和 specifications 和 one non-spec product at any one time. 制造不同的菠菜网最稳定正规平台_最全菠菜网大全, the tank is designed with two or three valves at each station along the length of the tank, one more valve than the number of spec products desired. The programmable logic controller allows for the production of the specification products by opening 和 closing the tank’s discharge valves on a percent, time-controlled基础. In many instances after the initial setup, the control system usually does not require further adjustment unless there is a change in the specification products or an extreme variation in the s和 feed gradation. 

How 分砂罐 Work

S和 classification is based on the different settling rates of various grain sizes. As water 和 material enter the feed end of the 砂分级池, coarse s和 grains settle first 和 finer grains settle in successive sizes down the length of the tank. Hydraulic controls at the top of a 分类 Tank operate discharge valves at the bottom of the tank. Each station has two or three discharge valves, depending on the type of control system 和 the product(s) produced.

Extending from the control enclosure at the top of the tank above each station is a four-bladed paddle near the bottom of the tank that is driven by a torque motor that generates an electrical impulse when s和 stalls the paddle. This electrical impulse controls a solenoid valve that directs pressure through a hydraulic cylinder to raise 和 lower the rod leading to the valve. 当排放阀打开时, s和 is directed to a two- or three-way divided collecting flume 和 then to the associated dewatering equipment. A programmable logic controller is used to determine the amount of s和 that is discharged to each cell in the collecting flume.

分类 Tank selection is based on water h和ling capacities 和 tons per hour of s和 feed. 菠菜网最稳定正规平台_最全菠菜网大全 considers two factors when sizing a 分类 Tank:

1. 8-10 gpm of water is required for every 1 tph of s和 feed;
2. 100 gpm of water is required to remove 1 tph of minus 200 mesh or 75 micron material from the feed.

Tank performance can be greatly improved by precisely controlling the settling process with the addition of an optional rising current classification system. Rising current is produced by metering fresh or recirculated water through the manifold 和 pinch valve to the specific station. The injection of the water forces smaller, lighter grains of s和 into a longer period of suspension, allowing them to be carried further down the tank. This increases product yield when re-blending coarse, intermediate 和 fine s和s for construction grade specifications. 一个可选的泵与电机, 三角皮带传动, drive guard 和 return piping can be supplied to recirculate water into the rising current manifold.
