The various separate raw materials are merged based on a range of different dry mixing methods. AVA mixers are used, for example, for manufacturing cement types such as Portland cements or trass. The addition of certain highly abrasive additives such as granulated slag, pozzolan, fly ash, and limestone allows you to obtain special cements with different chemical and physical properties.
The homogeneity of the various cement components in accordance with DIN 1164 (EN 197-1) is an essential requirement for the building materials industry, partly because long service life under extreme conditions must be ensured.
AVA HTC (batch operation) and HTK (continuous operation) series turbulent mixers fully meet these requirements and thus deliver reproducible top-quality mixes. Thanks to the mixing intensity in a compact design, high throughputs of more than 500 t/h can be achieved.
A wide product range is one of the hallmarks of the dry mortar industry. Whether masonry mortar, plasters, leveling compounds, tile cements, sealants, or fillers, knowledge of the production processes and the mixing accuracy of aggregates is essential in order to design a suitable mixer. Also, the machine must allow for easy reconfiguration as regards products and colors to facilitate frequent production changes. AVA HTC series batch mixers are especially well suited to these requirements. The modern and sophisticated technology guarantees consistently good mixing results with 100% repeatability. The degree of automation of the plant as a whole is variable, so even small quantities can be fed into the mixer manually. Special flaps that open along the entire length of the drum reduce discharge times and enable nearly complete batch mixer discharge in the range of > 99.5 percent. Blade heads can be integrated into the mixer drum sides in order to support the main agitator. These high-speed agitator components ensure additional dispersal of small components for color pigments and prevent agglomerate formation.
Individually designed type CCU feeders, up to 10M long, for transporting raw materials, including hot product, within the processing plant. Usually totally enclosed and dust proof designs, with unbalanced motor drive giving a fixed feed rate. Available to operate on inclines, in addition to the more usual installed horizontal or declined positions.
The classic type FCE electro-magnetic driven feeders with infinitely variable feed rate manual or automated control are utilised to handle the clinker, either in tunnel recovery systems under mass clinker storage facilities or under silos. The feeders and the integral hopper bottom sections are usually lined with special abrasion resistant liners.
Utilising the classic type FCE feeder with integral hopper bottom section, the standard units used would normally be either 400, 560, 800, 1000 or 1250mm wide, covering the capacity range of 0 - 500TPH. Normally supplied in totally enclosed dust proof designs. The electro-magnetic driven feeders allow for very accurate and automated discharge and dosing to be achieved.
finished cement skimming screens
Specially designed totally enclosed protection screens to skim off any oversize prior to bulk storage or bagging. Internal design features prevent 'flushing'. The units are usually 1000 or 1250 mm wide, handling up to 125TPH.
dosing to batch weigh hoppers
Custom designed totally enclosed and fully dust proof feeders are mounted directly under silos and silo dischargers for dosing to batch weigh hoppers. With infinitely variable electro-magnetic drives, they can offer very accurate fast and dribble feed rates directly into the weigh hoppers, with fully automated control, and instant stop / start. Available in widths between 400 - 1250mm.
discharge from batch weigh hoppers
Similar to the batch weigh hopper dosing feeders, custom designed fully dust proof electro-magnetic driven feeders are utilised for transporting the batch to elevators or conveyors. The infinitely variable feed rate control allows for the optimum flow rate to be selected for the subsequent material handling equipment. Totally automated control allows for 24 hour continuous operation from a central control room.
Vibratory transfer feeders are used extensively to convey both mixed batch and individual materials throughout the glass batch plant. They can be either electro-magnetic driven for infinitely variable feed rate control, or unbalanced motor driven for fixed feed rate operation. They are custom designed to match the plant requirements, and usually totally enclosed and fully dust proof. They can be arranged for either base mounting or overhead suspension.
