Automatic sand powder production line for metallurgical casting

Abstract

The invention relates to an automatic sand powder production line for metallurgical casting. The production line comprises a crushing machine, a grinding machine, a batching machine, a granulator anda calcining rotary furnace which are sequentially arranged, a cage-shaped rotor in the grinding machine is connected with an electrostatic dust collector, the electrostatic dust collector is connectedwith a first fan, a magnetic separation impurity removal device is arranged at the bottom of a material distribution device at the bottom of the electrostatic dust collector, a horizontal stirrer anda first screw conveyor are arranged in the batching machine, a cyclone dust collector and a second fan are arranged between an air inlet pipe and a smoke outlet pipe of a first feeding shell of the calcining rotary furnace, and a screening device is arranged on one side of a second discharging shell of an air cooling rotary cylinder. The whole production line achieves automatic production, the number of machining and transferring devices is reduced, the device cost and occupied space are remarkably reduced, the treatment amount is increased, quality control and production of smelting and casting sand powder with different water content, different magnetic impurities, different particle sizes and different raw materials are achieved, the machining treatment efficiency and effect are improved, continuous production is facilitated, and one set of equipment can meet various smelting and casting sand powder production requirements.

Description

technical field

[0001] The invention relates to an automatic sand powder production line for metallurgical casting, belonging to the technical field of metallurgical casting sand powder production equipment. Background technique

[0002] Ceramsite slag removal sand, recarburizer, purifying agent and other smelting sand powder are used in the smelting and casting industry to remove impurities in molten iron and molten steel or to add carbon to steelmaking and ironmaking, etc., which help to effectively prevent slag inclusion defects in castings and improve the quality of castings. Intrinsic quality, improve the yield of castings, reduce production costs, and are widely used. The production process of smelting sand powder generally adopts the production process of crushing, grinding, batching, granulation, and calcination. A set of production equipment cannot meet a variety of processing needs. At the same time, the production line also has a large number of processing and tr...
