ZIPPE has extensive experience in planning, constructing and building batch chargers. These, virtually, belong to the DNA of the company. 1953, Alfred Zippe senior developed the first fully automatic batch charger for the glass industry. Herewith, it all began and we are still building our batch chargers in our company in Wertheim. Our long-time experience and our high manufacturing quality is retrieved in many details of our machines. BATCH CHARGER – TYPE V I B R O T U B E ® GOOD VIBRATIONS. C U R R E N T L Y P R O B A B L Y THE M O S T M O D E R N , A D V A N CED AND E F F I C I E N T C H A R G E R ON THE MARKET. The VIBROTUBE®-Charger was especial- ly developed for feeding container glass furnaces. This modern, patented batch charger ensures a completely closed doghouse and also shows considerably lower wearing compared to alternative systems. Due to the closed doghouse and the optimized charing pattern valua- ble meting energy is saved. The VIBROTUBE® stresses impressively our experiences for decades in the field of batch charging.

N O e m is s i on Low X onsumption Low energy c 01 SEALED DOGHO U S E The heat protection shield is executable in a round and straight design and seals the doghouse completely. Therefore, the heat protection shield adapts perfectly to the furnace conditions. The two pushers in front of the vibrating tubes as well as their movements are executed in a way that there is no opening in the outlet area. Thus, in fact a dust free encapsulation of the doghouse is effected. As an uncontrolled inflow of air is elimi- nated, a significant reduction of NOx emission is the result. 02 VIBRATING TUBES The batch is transported to the melting furnace through vibrating tubes. Compared with alternative solutions, e.g. screw chargers, this conveying technology has a big advantage: The material is transported through vibrations nearly without con- tact, which reduces wearing significantly. The results are longer lifetimes and significantly lower operating costs. Furthermore, the front part of the vibrating tubes being situated in the melting furnace is water-cooled in order to avoid any batch caking. 03 LINEAR DRIVE The two pushers divide the batch conveyed into the melting furnace into small portions. This leads to optimal batch melting due to the larger heat contact surface of the batch. The push- ers are driven by a servo gear motor which is infinitely variable. Thereby, stroke length and lifting speed can be individually adjusted to the desired requirements.

BATCH CHARGER – TYPE E V P MANYFOLD TRIED AND T E S T E D , S O P H I S T I C A T ED N O N - D E S T R U C T I B L E – OUR EVP BATCH CHARGER Due to the special construction of the EVP charger and the use of a heat protection shield a charging at relatively small doghouse openings is possible while at the same time sealing the dog- house. Heat loss is reduced. The capacity of the batch charger can be continuously or discontinuously regu- lated by a command signal of the glass level controller. By dividing the batch into small portions by means of the pusher a bigger contact surface and herewith faster melting is possible. ZIPPE batch chargers type EVP rank among the most uncom- TECHNICAL plicated and most reliable batch chargers on the market. For DATA example, they can be applied for all container glass doghouse types. Conveying capacity: 50–500 t / 24 h max. 1 t Weight: Due to a very big outlet opening the amount of cullet can add up Machine width without to 100 % without leading to blockades. EVP batch chargers are heat protection shield: 1,000 mm situated in front of the melting furnace. By this all areas are well Doghouse depth: min. 600 mm accessible. For maintenance work (e.g. exchange of pusher) Swiveling angle: ± 10° the batch charger can easily be pulled away from the furnace. Stroke: up to 350 mm This reduces production downtimes and maintenance costs Water connection: 1x1½ tremendously. Total water consumption: 10–15 l / min 4
BATCH CHARGER – TYPE ECD THE ECD, A CLAS S O F I T S O W N The charging capacity will be determined automatically by the glass level controller due to change of the motor speed. This batch charger makes it possible to charge batch onto the melting surface while avoiding a fall and thus also avoiding Intermediate pusher and hopper are fixed on a swivel unit dust generation. which can be swiveled by 35° / 44° by means of an electrically operated cylinder. This guarantees an optimal batch charging. The pusher pivots from side to side allowing good directional Three positions can be chosen. The stroke length of the pusher control of the material flow and an even addition of batch onto can be adjusted manually. the melting surface. The design of the batch charger allows the doghouse to be sealed. Thus, energy is saved. DESIG N The batch charger consist of a feeding hopper with heat protection shield, water-cooled pusher, swivel device and supporting part. FUNCT ION From an intermediate hopper batch flows into the doghouse which is pushed into the glass melting furnace by means of a pusher which is driven by a frequency control gear motor.

The batch is fed into the furnace via a vibrating chute driven by an air piston vibrator. The vibrating chute can be replaced by a conveyor belt for specific applica- tions. Furthermore, beside rectangular furnaces also hexagonal furnaces can be fed. The charger moves both from left to right and from front to back during the charging process. The charging rate is adjusted optimally by a glass level control unit to meet the furnace conditions. Each Cold-Top charger is customized and multiply tested and proven. 6
BATCH CHARGER FOR FLAT GLASS FURNACES THE FLOAT GLASS C H A R G E R – BIG, ROBUST, EF F I C I E N T The use of several machines in one doghouse allows the stream of glass batch to be directed individually both in terms of direction and volume, thus making optimum charging of the furnace surface possible. ZIPPE flat glass chargers can be configured for all doghouse widths. The chute is air-cooled on standard. If requested, we can deliver in water-cooled design, as well.
