cdocast desktop mini gold melting furnace is specially designed for melting small volumes of kg of gold or silver. this small gold melting furnace comes with induction heating technology which can reach temperature to
cast irons include many metals having a wide variety of properties. although cast iron is often considered a simple metal to produce and to specify, the metallurgy of cast iron is more complex
this mini gold melting furnace is designed small size, does not occupy space, simple operation. this mini gold melting machine comes with temperature control device, the temperature changes can be observed during the entire operation.
for the massive crystalline graphite ore, because of the high-grade carbon in itself, finer particle sizes and the smaller reserves, we can adopt the traditional crushing and hand picking technology to take advantage of it. this graphite mining process has the advantages of simple production process and low production cost.
show students a chunk of graphite from an old historic mine in new hampshire. they will be fascinated with the idea of writing with a piece of mineral. use a battery, wire, and bulb to show that graphite conducts electricity. each sample is about one pound of graphite and may contain some rock matrix. graphite from president pierces mine was used to make pencils in the century. In 1849
above is the graphite use. It can be bought at the graphite store quite cheaply, but you will need to machine it to the proper dimensions in order to make a good nozzle. below is the aluminum being machined. the outside diameter is just a hair over which is fine, and it is cut to the length need, then drilled, and hollowed out in order to make a perfect fit with the graphite.
