Development and manufacturing the dosing and process equipment for the glass furnace batch production shops. The glass furnace batch is a multi-component mixture, which can include 7-10 bulk components (sand, field spar, alumina, dolomite, soda, sulfate, chalk, saltpetre, coal, crushed glass, etc.), 1-2 liquid components (water, mortar saltpetre, oil residuals, etc.) and micro-additives (selenium oxides, cobalt, arsenic, etc.). This mixture is subject to high requirements for the dosing accuracy of components at a high process productivity, for the uniformity in chemical and grain-size composition of raw materials.
Significant factors that influence the quality of the glass furnace batch are also the supply sequence of the raw materials to the mixer and their mixing duration. The optimal mixing time is from 1.5 up to 3.5 minutes for different types of mixers and one charge size. Value of the dosed portion supplied to the mixer varies from a few grams up to 2-3 tons for different materials.
Variety of the manufactured feeders and process equipment, combined with an automated control system, allows to make an optimal choice of the dosing equipment design, mode of loading and unloading of the batchers, method of weight dosing, depending on the physical and mechanical properties of the material, dose size and required productivity. The automated dosing and mixing complexes of small additives, which allow preparing and dosing a premix i. e. a preliminary mixture of microadditives and a small amount of the main component of the furnace batch (filler) are designed to improve the accuracy of dosing the microadditives and their uniform distribution in the mixer.
«Stromizmeritel» Ltd pays a great attention to the preliminary processing of off-spec raw materials and, if necessary, their enrichment in order to improve the quality of the glass furnace batch in the engineering designs. Experience in engineering the glass furnace batch production, which includes all the main processes for the preparation of multicomponent mixtures, allows to implement the projects and to manufacture the equipment for the production of dry mixtures, refractory composite mixtures, mixtures for the production of electrodes, furnace batches for manufacturing the heat-insulating materials, etc.
Optimal solutions to the problems of dosing liquid and well-flowing bulk materials, clumping and highly hygroscopic components of the glass furnace batch
Special equipment for dosing the micro-additives (colorants, decolorizers) and small components
A flexible system of the mixer settings: mixing time, timing and order of the materials feeding
The structure of the furnace batch transportation equipment allows minimizing the separation, clumping of the furnace batch, reducing its moisture content, and material spillage
Optimal selection of furnace batch and crushed glass loaders, taking into account the glass melting furnace structure, its loading buffer, melting capacity and nature of melting
Obtaining the standard raw materials corresponding to the specified characteristics: moisture content, size fraction and chemical composition by the process of preliminary processing of the raw materials
