Abstract

The invention discloses a method for electric pulse pretreating on tourmaline by utilizing a high-voltage electric pulse device. The method adopts the high-voltage electric pulse device, and comprisesthe following steps that (1) a water pump is started, so that water continuously enters a pulsating insulating cylinder, and is continuously discharged from a product collector; (2) tourmaline ores are conveyed into the pulse insulating cylinder through an ore feeding bin, and are accumulated on a screen to be in contact with a high-voltage electrode; (3) a power supply is started to enable discharging is conducted between a piezoelectric electrode and a high-voltage negative electrode, so that the tourmaline ores are crushed; (4) an eccentric wheel is driven to rotate so as to enable a pulsating cone-shaped body to move up and down periodically, and enable small particle parts in the tourmaline ores on the screen to gradually move downwards; and (5) the crushed tourmaline ores enter theproduct collector through a pulsating device. The method has the advantages that the treatment time is short, the production efficiency is high, the energy consumption is low, crushed products are free of pollution, and the subsequent deep processing of the tourmaline is facilitated.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a method for pretreating tourmaline electric pulses by using a high-voltage electric pulse device. Background technique [0002] Tourmaline is a general term for tourmaline minerals. It is a ring-structured silicate mineral characterized by boron and very complex in structure and chemical composition. The Mohs hardness of tourmaline mineral is about 7-7.5, and the density is 2.9-3.25g / cm 3 Between; With the development of technology and the continuous research of mineral materials, tourmaline is gradually widely used in environmental protection, chemical industry, transportation, textile, air purification, food and medicine, water quality improvement, architectural decoration and shielding electromagnetic radiation and other fields. [0003] Tourmaline has permanent spontaneous polarization effect, piezoelectricity and pyroelectricity, can release negative...
