High Voltage Four Roller Electrical Electrostatic Separator

High tension electrostatic separator is designed for separation of titaniferous mineral sands, hard rock ilmenite and rutile, cassiterite, tantalite, wolframite, iron ore, plastics from metals in waste recycling system.
 
 High-tension electrostatic separators utilize the electrical conductivity difference between the various minerals within an ore feed. The high-tension roll electrostatic separator (HTR) utilizes a grounded roll to transport feed material through the high voltage ionizing field (corona) where particles are charged by ion bombardment. Conducting particles pass their charge to the grounded carrier electrode (roll) and are therefore free to be thrown from the roll by centrifugal and gravity forces. Non-conducting particles are pinned to the carrier electrode and are transported further around the roll periphery, where they drop from the electrode surface, either because their charge dissipates, or by mechanical means, e.g. brush and high voltage AC wiper.
 
Throughput capacity of a high tension electrostatic separator is closely related to the roll speed, roll width, and characteristics of the feed material. For a roll with a smaller diameter, a higher rotation speed is required in order to maintain a substantial feed rate. However, at higher RPM, coarse, non-conductive particles tend to leave the roll surface too early due to the increase in centrifugal force resulting in a large portion of misplaced non-conductive particles in the conductor stream. Vice versa, under a low RPM condition, fine conductive particles do not gain enough inertia to be thrown off the roll, resulting in misplacement of the nonconductor stream. Therefore, for the treatment of particle mixtures with a range of physical characteristics, including conductivity, particle size, and density, it is necessary to adjust the roll speed and electrode positions to optimize the process.

The uPVC window welding machine is major and essential equipment for manufacturing uPVC windows and doors. The machine heats the end of uPVC profiles into molten state through heating plates, and then fabricates the uPVC profiles into a window frame unit or window sash unit by pressing. The movements of profile clamping, profile melting, and frame fabricating are controlled by a PLC, and all the movements are finished step by step automatically. Welding is the most important step for making uPVC windows and doors, and the welding quality (such as welding strength, welding-angle accuracy, window size accuracy) will affect the finished window quality directly. STONE window machinery guarantees the welding quality of the uPVC window welding machine through use of high quality heating plates and temperature controllers, high accuracy liner bearing motional pairs and other high quality machine components, and through our strict quality control system.
