The Sider Technology company operates in the foundry sector, designing and building machines and plants in Italy and abroad. Thanks to the many years of experience of its employees, the company is a reference company both for NO-BAKE foundries and for all those cast iron foundries that want efficient, economical and low environmental impact casting technology.
Initially used in small foundries, currently there are rotary kilns operating with a production of 15/20 t / h. Particular sensitivity towards the environment is also demonstrated thanks to the construction of sand / silicate recovery plants in addition to those for sand / phenulfuran resins: the use of silicate is an excellent technological innovation when compared to that of resins.
At the moment we can count on numerous functioning plants built with our technology in Europe. The company activity is organized starting from the design of the system, to move on to construction, pre-assembly and checks, to finish with on-site assembly and testing, as well as subsequent maintenance and technical assistance.

Sand/silicate reclaming
The sand reclaiming process is subdivided in more steps:
The vibrating shakeout equipment crushes the sand blocks, in order to turn them to grains or to
very small size. Metallic parts, stones or other foreign matters are kept by a screening surface
and are discharged through a pneumatically opened shutter
Sand coming from the shakeout is conveyed upwards through suction. During such transport it
undergoes, because of the speed, a crushing and a rubbing of the grains
In the decantation chambers, a first separation and elimination of dust is carried out
The de-dusted and treated sand is screened, leaving to pass the definitively selected one to
the successive phase
Through the hot-air fluid bed, the grains are heated and dried, in order to favour the shattering
of the silicate film covering them. Afterwards the rubbing of the grains inside the abrading mill
pulverizes the silicate film, while dust is removed and stored in the hopper of the proper sleeves filter
The sand is cooled uniformly in a heat exchanger with finned tubes batteries before its definitive ensilage
A pneumatic propulsor, placed under the cooling-unit, conveys sand to the usage point
In order to improve the quality and to optimize the silicate consumptions, sand is treated for a
last time in a final dust exhausting group provided with an adjustable cascade system. In such
way also the residual fines together with dust produced during the pneumatic conveyance are
captured, and you obtain a sand with eccellent granulometry features
Chromite sand separation plant
By means of electromagnetic drums, SIDER TECHNOLOGY chromite sand separator
allows to separate chromite sand from silica sand.
For greater efficiency, the plant is equipped with a sand dedusting device with a dedicated filter or, if present, it is possible to connect it to the centralized foundry suction
system.
Gravity sand cooler
Sider Technology gravity sand cooler is composed of an upper storage tower formed by a plenum
chamber, a series of batteries of finned pipes and, in the lower part, a pneumatic shutter for sand
discharging in the collecting hopper.
It is available in two variants: with water cooling by means of an evaporating tower, or by the combination of the latter with a refrigerator to ensure the lowest and most constant sand outlet temperature.
