FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is part of the technical sector of the industry dedicated to the manufacture of cement.

BACKGROUND OF THE INVENTION

As is known, cement is a binder formed from a mixture of calcined and subsequently ground limestone and clay, which has the property of hardening on contact with water. Mixed with stone aggregates (gravel and sand) and water, it creates a uniform, malleable and plastic mixture that sets and hardens, acquiring stony consistency1 called concrete or concrete and whose use is very widespread in construction and civil engineering.

The cement manufacturing process comprises four main stages:

-

Extraction and milling of the raw material.

-

Homogenization of the raw material.

-

Clinker production.

-

Grinding of CP.mP.nto.

The raw material for the manufacture of cement (limestone, clay, sand 1 iron ore and gypsum) is extracted from quarries or mines and, depending on the hardness and location of the material, certain operating systems and equipment are applied. Once extracted the raw material is reduced to sizes that can be

processed by crude mills.

The homogenization stage can be wet or dry 1 depending on Sl air or water currents are used to mix the materials. In the wet process the mixture of raw material is pumped into homogenization rafts and from there to the furnaces where the elinker is produced at temperatures above 1500 ° C.

In the dry process, the raw material is homogenized in yards of raw material with the use of special machinery. In this process the chemical control is more efficient and the energy consumption is lower, since by not having to eliminate the added water in order to mix the materials, the furnaces are shorter and the clinker requires less time subjected to high temperatures

The clinker obtained, regardless of the process used in the homogenization stage, is then ground with small amounts of plaster to finally obtain cement.

The cement manufacturing process ends with the joint grinding of clinker, plaster and other materials called "additions."

Said cement grinding is done by mechanical equipment in which the mixture of materials is

subdued

to impacts from bodies metallic or to forces from

compression

high. For it be use the

   following equipment:

Roller press

Vertical roller mills

Ball mills

5

Horizontal roller mills

Well, the objective of this

invention is to develop a plant intended

only to the final part of the manufacture of the

1 o

cement, that is, grinding, that is modular and of

small dimensions to give it a character

both fixed and temporary and / or transportable, to

unlike conventional installations that

They are usually large and only of character

fifteen

fixed, and that are normally intended for grinding

of large volumes of material available

normally in the same facility where they are taken to

carry out the rest of the previous manufacturing processes of the

cement.

twenty

In addition, the invention aims to develop a

plant that can be transported and installed so

fast and simple in locations other than

installation of the rest of the manufacturing processes of the

25

cement, and allow cement supply in

Small volumes and in isolated markets.

On the other hand, in reference to the current state of the art it should be noted that by the

The applicant is not aware of the existence of any other modular plant for cement grinding or invention of similar application that presents technical, structural and constitutive characteristics similar to those presented here, and whose

Characterizing details are conveniently set forth in the final claims that accompany the present specification thereof.

EXPLANATION OF THE INVENTION

Thus, the modular plant for cement grinding that the present invention proposes is configured as a remarkable novelty within its field of application, since in accordance with its implementation and in a restrictive way the aforementioned objectives of granting it a character so much are achieved satisfactorily fixed as temporary and / or transportable thanks to its innovative structural configuration based on modules of small size and standardized dimensions according to the dimensions of the transport containers.

For this, what the invention proposes is a new type of modular plant for cement grinding whose novelty is the fact of having all the equipment integrated within independent modules where each of said modules is of the configuration and

size of a standardized container, of the type conventionally used to transport

goods.

So,

the cited phase from grinding from cement,

that

from shape conventional be makes through equipment

that

understand essentially hoppers from reception,

mills or roller press, separator, filter, fan, bagger and control room, between other equipment or devices, are distributed along several modules that can be attached to each other, where each module is inscribed within the dimensions of a Merchandise container of standardized measures.

So! and preferably but not limiting! The plant has a first module where the hoppers for receiving raw materials are located.

In a second module a ball mill or a roller press is incorporated.

In a third module you will find a dynamic separator! the upper body of a filter and the process fan.

In a fourth module the filter hopper is incorporated! which! at the same time! It is made of cement silo.

Y,

by latest, one fifth module incorporates a

bagger

and one room from control / despa cho for he

operator.

It is important to note that the aforementioned modules! that as noted above

they have a configuration and dimensions according to those of the standard merchandise containers, they are configured, preferably! also as such containers! that is, with the anchor jes that allow its stacking and anchoring with each other! being able to be formed, for example, from open metal structures, based on tubular elements and / or profiles, or by closed metal structures based on boxes with partitions and doors or gates inside, counting in such case with holes, holes and / or doors or additional gates for the coupling between the different equipment incorporated inside, as well as for the coupling of the additional intermediate elements of conduction of the material between one module and another to allow its

correct operation, that is, the grinding of the cement.

For the transfer of the plantI it will be enough to disassemble the different additional coupling elements and each module can be transported by manipulating it as a conventional container, with the advantage that during said transport the different equipment is protected inside each module avoiding possible deterioration and allowing its storage in an orderly manner and occupying a minimum space.

The sales provided by the proposed plant are essentially the following:

~ Maximum simplicity of the installation.
