Dear Current Administrators of TBA, Stop erasing posts and topics. All of you. As a regular of TBA who loved it dearly, you have no idea how much it kills me that so many topics were left to the trash without member consent. And it wasn't just drama posts -some of you deleted any post that you didn't like, from roleplays, from anything...you deleted the entirety of A Very Potter Roleplay, as an example. As the creator of that roleplay, I realize it was somewhat of a failure, but the fact that it was erased without my consent is upsetting, and there were a few members who enjoyed it. I realize that there were some things posted on TBA that many of us are not proud of. Drama and the like. But even with that drama, TBA was so, so, important to me, and others. Yet, certain moderators have ignored this and have erased topic upon topic -that showed in the Administrator history. Even if you say it was only a single topic or a single post, the forum has been trimmed down. You say this is only "cleaning up the forum," but it's erasing our history, and I won't stand for it. To those of you who've returned to this forum only to remove things periodically, please stop. It simply isn't fair to those of us who are nostalgic and like looking back, and I know I don't speak of myself alone. With all due respect, LL.

Inorganic needle-like wollastonite is a kind of mineral, its characteristic non-toxic, resistance to chemical corrosion, thermal stability and the size stability is good, have a glass and pearly luster, low water absorption and oil absorption value, mechanical properties and excellent, and has certain reinforcing effect, wollastonite after processing of mine pulverizer into silicon ash powder, can be more widely used in automobiles, metallurgy, ceramics, plastics and other industrial production.

Wollastonite consumption in the world outlook is a promising field of engineering plastics industry, wollastonite as packing and reinforcing agent, plastic rubber industry in the manufactured products are increasingly alternative metal parts, rapid growth in demand for its. Now is widely used in the market of silicon ash powder particle size between 200-325 mesh, Shanghai build smelting as specializing in the production of flour mill equipment of high-tech enterprises, single fine degree requirements for the general customers recommend YGM high pressure grinding mill, Raymond mill, sand.

As time progresses, however, the development of comprehensive utilization of resources, the issue of environmental protection advocate, processing methods of wollastonite in production technology and production equipment performance improvements, even further the fineness of the product itself specification strictly, from the traditional mill grinding of silicon ash powder will gradually cannot meet the demand of market, only by grinding with super fine crushing ability to wollastonite powder equipment for ultrafine grain production, and its potential new applications, gradually expanding its service areas.Dental crown machine press furnace dental zirconium sintering furnace
