ELECTRICAL ROLLER KILN, Series ER
The kiln consists of a sturdy steel structure, which encloses the thermal insulation, consisting of low density refractory bricks and preformed ceramic fibre sheets, highly resistant to high temperature and thermal shock.
The kiln has several zones with different characteristics, viz.:
* Entrance and smoke evacuation zone
* Preheating zone
* Firing zone
* Cooling zone.
Material transport system
The transport of the tiles in the kiln takes place by means of ceramic rollers, which are rotated by means of a pinion-chain system with variable speed.
The drive system makes it possible to exchange the rollers in a very short time.
The combustion system consists of electrical heating elements in Kanthal in spiral form, supported by ceramic tubes and easily exchangeable.
In models ER 10 - ER 15 – ER 20 – ER 25 – ER 30 – ER 45 the heating elements in the firing zone are made of silicium carbide, enabling these models to work at a max. temperature of 1.330°C.
Each zone provided with heating elements (preheating and firing zones) is controlled by a self-regulating potentiometric pyrometer, which controls the static units.
In the firing zone of the kiln, the upper and the lower part can be separately controlled.
Automatic control of the cooling zone with automatic opening and closing of the chimneys with the exception of model ER 10 and ER15.
Control panel, regulation and indication
The control panel consists of a steel sheet encasing, containing all equipment needed to control the kiln, such as:
· Main switch
· Motor safety switches
· Push buttons on/off
· Signal lights
· Electrical circuits for the start-up and control of the various devices of the kiln
· 1 Pyrometer for each controlled zone
· Static units
· Optional: Control of the kiln by a PC
In models ER60, ER80 and larger ones, the uniformity of the temperature (between right and left hand side) of + 3°C is electronically controlled.
