The mixer or muller is rightly considered to be the pulsating heart of the sand plant. Obviously, it is the most important machine where ideal conditions of moulding sand are restored.
Over the years, the market has been invaded by the most various types of mixers: from the first mixers with scrapers to the actual intensive mixers. Today, a mixer must satisfy the following requirements:
a) Production of constant quality sand
b) High productivity
c) Reliability
d) Reduced maintenance.
In our opinion, to meet these requirements it is necessary to combine the activity of the mixer with a sand control which supervises its functions.
In fact, they are to be considered as two parts of the same system: arm and mind.

The cooling of sands coming from shakeout is extremely important in order to avoid problems due to excessive temperature, such as difficult bentonite activation, difficult control of prepared sand compactability, higher water demand, etc..
The aim is to obtain sand with a temperature below 45°C. We think it is likewise important to favour the maximum homogenization of the sand itself.

The reflux cooler is especially suitable for granular free flowing bulk materials, as it is a contact cooler. The material to be cooled slowly flows along the water cooled cooling faces in counter current fashion. Water does not of course come into contact with the bulk material.
The special design of the contact areas between the cooling segments and the cooling spirals ensures that a high degree of heat exchange is achieved. A constant temperature of the cooled bulk material is achieved by automatically controlling the flow of cooling water.
The reflux cooler is compact in design, e.g. 260 m² of cooling faces are incorporated in a cooler of 1 m³. The result is a high cooling capacity in the smallest volume. Furthermore, due to the modular construction, sections can be added to increase cooling capacity. The complete cooling face is used to its optimum advantage, as a corresponding dosage closure device guarantees an equal distribution of the bulk material throughout the cooler.
The reflux cooler can also be used to heat free flowing bulk material.

Foundries are always striving to improve the quality and the precision of their products, as well as aiming for the continual reduction of costs. The quality of cores has a very important part to play in reaching these objectives.
PRIMAFOND is constantly researching the most simple and efficient solutions, making core sand preparation and distribution systems of various types and for several processes, either simple or complex, according to the customer's requirements.
For the sand and resin mix preparation, the best mixing and homogeneity are obtained with batch mixers. The batch mixers made by Primafond, model MER 50 - MER 100 - MER 150 - MER 200 are of a all-steel construction, with wear-resistant mixing components, which are replaceable.
One batch mixer MER can together with a distribution system, feed one or more core-shooter machines. The use of only one mixer for many core-shooters gives many advantages including a practical and efficient installation and savings in maintenance operations.
Primafond makes simple, efficient and automatic systems for mixer sand charging, resin dosing and sand-mix distribution to several core-shooter machines . Our long experience in this field ensures excellent results.

Cold resin bonded sands are mechanically reclaimable. A large proportion of the sand which has been reclaimed using the conventional type of single phase mechanical reclamation unit can be re-used.
The used sand portion of the moulding sand can be considerably increased and the new sand requirement correspondingly reduced by the installation of a second reclamation unit.
Lower new sand costs! Lower dumping costs! Lower transport costs!
The ROTAREG reclamation unit is intended for such applications and is particularly suitable as an addition to existing single phase plants.
The reclamation unit ROTAREG consists of the following parts:
- centrifugal force cleaner
- pneumatic conveyor
- fluid bed screen

Green sand control in foundry has always been one of the main goals to be achieved in order to obtain good quality productions and to minimize scraps. So far, sand control methods were mainly based on the control of return sand moisture and on the consequent water addition to muller to obtain the desired moisture of prepared sand. There are also control systems which determine the compactability of mulled sand and then determine the quantity of water to be added.
All these systems give a partial answer to the demand of quality sand, in particular of constant quality sand. In fact, they do not allow the automatic control of important parameters such as strength, active bentonite, total bentonite, permeability and automatic addition of additives and new sand.
