    • This invention relates to purified natural glass products having low concentrations of soluble substances. More particularly, this invention relates to purified natural glass products having low slurry electrical conductivities (i.e., less than about 18 .mu.S-cm.sup.-1). Preferred embodiments are further characterized by low concentrations of soluble iron (i.e., less than about 2 mg Fe/kg product) and/or low concentrations of soluble aluminum (i.e., less than about 10 mg Al/kg product). These products may be prepared from natural glasses and natural glass products, including, for example, expanded perlite, pumice, expanded pumice, and volcanic ash. The products of the present invention retain the intricate and porous characteristics of the feed material but possess low concentrations of soluble substances, thereby permitting much greater utility, particularly in filtration applications.
    • 本发明涉及具有低浓度可溶性物质的纯化天然玻璃制品。 更具体地,本发明涉及具有低浆液电导率(即小于约18μS-cm-1)的纯化天然玻璃制品。 优选的实施方案的进一步特征在于低浓度的可溶性铁(即小于约2mg Fe / kg产物)和/或低浓度的可溶性铝(即小于约10mg的Al / kg产物)。 这些产品可以由天然玻璃和天然玻璃制品制备,包括例如膨胀珍珠岩,浮石,膨化浮石和火山灰。 本发明的产品保留了进料的复杂和多孔特性,但是具有低浓度的可溶性物质,从而允许更大的效用,特别是在过滤应用中。

    • An apparatus for comminuting glass is disclosed having a housing. Within the housing are a plurality of weighted members or hammers, flexibly connected to and spaced about a rotatable shaft. A drive member rotates the shaft, causing the hammers to rotate about the shaft and define a rotation circumference. A glass intake opening located at the top portion of the housing is provided to introduce glass into the apparatus. A first adjustable plate is located adjacent the glass intake opening and positioned to provide a space between the first adjustable plate and the hammers' rotation circumference. A first glass suspension chamber is defined by the glass intake opening, the first adjustable plate, and the rotation circumference of the hammers. In operation, the shaft is rotated, causing the weighted members to spin about the shaft. A quantity of glass is introduced into the apparatus, and the weighted members contact the glass, causing the glass to strike the first adjustable plate. Adjusting the space between the first adjustable plate the weighted members' rotation circumference helps control the resulting particle size of the comminuted glass. Controlling the shaft rotation speed also affects the resulting particle size of the comminuted glass.
    • 公开了一种用于粉碎玻璃的设备,其具有壳体。 在壳体内部是多个加权构件或锤,其柔性地连接到可旋转的轴上并与其隔开。 驱动构件使轴旋转,使得锤绕轴旋转并限定旋转周长。 设置在壳体顶部的玻璃进气口用于将玻璃引入到设备中。 第一可调节板位于玻璃入口开口附近并且定位成在第一可调节板和锤的旋转圆周之间提供空间。 第一玻璃悬浮室由玻璃进气口,第一可调板和锤的旋转周长限定。 在操作中,轴旋转,使加权构件围绕轴旋转。 将一定数量的玻璃引入设备中,加权构件与玻璃接触,导致玻璃撞击第一可调节板。 调整第一可调节板之间的空间,加权构件的旋转周长有助于控制粉碎玻璃的所得颗粒尺寸。 控制轴转速也影响粉碎玻璃的所得颗粒尺寸。
