INSTALACIONES PARA GESTIONAR ÁRIDOS, PLANTAS FIJAS
MAQUINARIA ADECUADA PARA CUBRIR CUALQUIER EXIGENCIA
FIXED PLANTS
Aggregate treatment plants for small or large exploitations, up to 1300t / h of production. Turnkey projects with the necessary options to achieve aggregates and high quality sands, by complying with the regulations of processes, machinery and the final product.
Leaders in the market incorporate equipment for primary crushing, secondary and tertiary sorting, washing, and water recovery, dust collection and all existing variants for the different types of rock to be treated Limestones, granites and other abrasive rocks, you will find in Leblan the right machinery to get the product that our customers demand.
FIXED PLANTS
PRIMARY FEEDERS
Primary feeders with prescreening or without it, with robust receiving hoppers and variable capacities adapted to the production and granulomere of the material input for each installation.
BAND FEEDERS
Feeders band for transferring material evenly and continuously from a receiving hopper.
ELECTROMAGNETIC VIBRANT FEEDERS
This type of feeder is powered by an electromagnetic vibrator that is used as an adjustable flow meter. The regulation is carried out by means of an electronic control cabinet incorporated.
PRESCREENED FEEDERS
Located under a hopper, it regulates the flow of material and at the same time it separates in two or three sizes in the same process. Installable in fixed plants or mobile groups with the need to separate land or unwanted stuff.
JAW CRUSHERS
Designed to grind large sizes of rock entering the facility and reduce its size by preparing the incoming material to be crushed and later classified.
MILLS
MILL OF CONES
High productivity, low cost of maintenance and of wear, long mechanical life, high quality aggregate and variable sand proportion according to needs are the most remarkable characteristics of this type of crushers, suitable for highly abrasive materials.
IMPACT MILL
Impact mills for abrasive rock crushing. Designed to produce sands with high coefficient of reduction. Rotor with the change of direction of rotation for better use of the wear elements and it offers great performance. Special impact steel bars with high wear resistance. Hydraulic opening for easy maintenance access.
SCREENS
Inclined screens with free vibration drive allowing a wide range of amplitudes and speed. Suitable for all particle sizes and characteristics of aggregates; dry and washed, fine and thick, natural and crushed. Its design and robustness are ideal for use in all types of aggregate treatment facilities.
Screening surfaces from 2m2 up to 17m2 per mesh and models up to 4 floors. Diversity of mesh types to adapt to the material to be treated; metal, anti-matt, polyurethane or rubber, cascaded grizzly type.
CONVEYOR BELTS
Made with standard elements, it allows to cover all the needs of the material transportation, regardless of the length or production within the facility. Depending on the performance required we have conveyors manufactured in structure, folded sheet or in a standard profile.
Lightweight, durable construction, slender lines, possibility of fairing and access of a comprehensive inspection, variety of belt types and power and easy access for maintenance.
WASHING EQUIPMENT
CLEAN WATER TANK
The clean water deposit collects the clean water from the settling tank and reintroduces these in the circuit of the plant for use.
COMPACT WASH GROUPS
Washing groups are effective systems for good sand washing. Its main task is to separate the fraction less than 63 pm (microns) without losing the rest of fines sand so that the resulting product meets the quality requirements and the regulations. These equipment have a high performance and produce high quality sands even in the products with high content of clays.
These groups are composed of hydro cyclone, drainer, engine and pumps and can be configured depending on the particular needs of each client.
SETTLING TANK
The settling tank receives the dirty water from the process by the mixing box where it joins the flocculent solution. Inside the box, the mixture of dirty water and flocculent, are required to perform a given route by forming at this point the floc of a suitable size and an adequate content. After this operation, the mixture enters the tank through the central chimney where sludge is decanted and precipitates on the bottom of the tank.
DRAINERS
The main function of a drainer is to remove the excess water in the material outlet of the usual washing equipment. Two vibrators form the drive that produces a linear motion which transports the material to the outlet and favors the drainage of the same.
A polyurethane grid base with a design that prevents its obfuscating, filters the surplus water with great efficiency and in high quantity.
HYDROCYCLES
These groups are responsible for recovering the lost fine sand, by overflowing in washing equipment such as the washing trommels, the decanters or no end decanters. They are part of the washing groups. Hydro cyclones are also commonly used in industrial installations for the treatment of kaolin and siliceous sand.
WASHING TROMMEL
The washing trommel cylinders are intended for washing rocks, gravel and mineral that carry a high percentage of clays and soils, as well as the preparation, the disintegration and the homogenization of products that in subsequent processes will be treated wet. Great effectiveness and a guarantee of a perfect wash, and also an economical maintenance. The range of productions is between 100y and 300 t / h.
DUST COLLECTION
The dust collection takes place at specific points in the installation by means of bag filters which have an automatic cleaning system with periodic pressures of compressed air, which make it unnecessary to stop the gas flow or to isolate the chambers during the cleaning periods. This achieves maximum utilization of the filter surface. In addition, this cleaning system allows higher filtration rates.
All this leads to small size filters. The dust-laden gases coming through the dirty gas inlet to the filter chamber. The gases are disturbed in their way by a deflector that causes the thick dust to fall which in this way does not need to be filtered. The gases are distributed through the filtration chamber flowing into the sleeves, on the outer face of which the dust is retained.
The clean gases leave the filtration chamber through the inside of the sleeves reaching the clean gas channel where they leave the filter. The loose powder falls for the most part to the hopper. The cleaning air, with the dust that could have been carried, meets with the dirty gas and is filtered by the rest of the sleeves that are not in cleaning period.
