General Information
Sulphide iron ore mine is the largest sulphide iron ore mine in East China, the mine open pit and underground about 1 million tonnes of ore per year, due to the ore accompanied by copper, gold, silver and other metals, so about 800,000 tonnes of ore per year into the two processing plant for separation, copper selection after the tailings that is, sulphide iron ore products, so that sulphide iron ore dewatering gradual...
The sludge dewatering equipment of this enterprise has used belt filter presses and single screw solid-liquid separators, and the water content of the sludge is around 75%, and the sludge will eventually be processed in the captive power plant, but the sludge needs to be dried to a water content of around 60%. The sludge needs to be transported to the drying site, where it is regularly turned over and dust is dispersed...
In recent years, alkaline desulphurisation has been widely used in coal treatment and utilisation projects. At present, the sulphur foam in alkaline desulphurisation adopts the process of continuous sulphur melting in sulphur melting kettle to produce molten sulphur. The sulphur foam overflows from the regeneration tank to the foam tank, which is equipped with agitation to make the foam and clear liquid form a homogeneous suspension, and the foam is used to...
Reasons for utilising plate and frame filter presses
In the soda ash production process, brine refining is required to improve product quality, reduce ammonia, salt, and carbon dioxide losses in the production process, and reduce scarring in the tower piping. Raw salt is dissolved in hot water to make saturated crude brine. In the process of removing magnesium and calcium, a slight excess of stone is added...
A sludge incineration and disposal plant is proposed to be built in Hangzhou, where centrifugal sludge with a water content of 80% will be incinerated after deep dewatering using plate and frame. In order to improve the economic value of sludge incineration, it is very important to reduce the dry basis increment caused by the conditioner and not to reduce the calorific value of sludge in the pretreatment process, therefore, it is necessary to find a new agent instead of...
Application of diaphragm plate and frame filter press in acid bath backwashing
The acid bath in the acid bath plant is traditionally processed through microporous filters after the backwashing of filament beam filters. In the operation of the microporous filter there are the following problems: microporous filter rod Consumption of large, microporous filter use in the process of the highest rate of damage is the microporous filter rod, mainly for...
Changqiao Water Treatment Plant Project Introduction
Changqiao Water Treatment Plant was built in 1959, and after many times of reconstruction and expansion, the water supply capacity has reached 1.6 million m3/d, which is the largest water supply plant in China at present, and it undertakes the water supply task in the southwestern part of Shanghai city. The latest large-scale reconstruction of Changqiao Water Plant started in 2000, which is the reconstruction of the earliest 40...
Chemical cleaning of plate and frame filter presses in sugar mills
The current common production process of domestic beet sugar factory is the double carbonate method. The whole process is divided into 6 sections:
(1) sugar beet pretreatment
(2) sugar extraction (osmosis)
(3) Sugar juice purification
(4) Evaporation
(5) Sugar boiling
(6) Separation, drying and packaging".
Sediment separation process in the purification section...
Plate and Frame Filter Press
Plate and frame filter press is a commonly used mechanical equipment in the production process of mineral enterprises, and its main function is to filter and separate the ore. In the production process, the operation quality and efficiency of the plate and frame filter press is particularly critical, if the performance of the plate and frame filter press can not be guaranteed, or there are damages and failures...
