Multi-cyclone plant in Panama

Alquezar has developed a new project for GUPC in the Panama Canal.

This is a multi-cyclone plant to eliminate fines in the wash water of a basalt quarry. The crushing processes of the quarry were producing excessive fines, causing problems in the water clarifiers for its recovery.

With this multi-cyclone system, a cut-off at about 0.040 mm is achieved, eliminating the 0.040 to 0.600 mm fraction of solid fines contained in wash water of the quarry, before it reaches the clarifiers. The plant has a water processing capacity of 3000 m³ per hour.

Alquezar uses its extensive experience in the quarry water treatment and washing processes to develop this new and specific project.

Crushing Plant for GUPC in the Panama Canal.

Alquezar has sold a fine sand crushing plant for the quarry of the extension work on the third set of sluice gates of the Panama Canal.

The installation is comprised of two centrifugal crushers (VSI) model VA-2500 with 500 kW power each one, and a high frequency classification sieve with biflow system.

The objective of the crushing plant is to produce 0-1.5 mm fine sand, from a feed of 1.5-19 mm basalt.

The VSI crushers are configured with closed rotor and impact anvils, to crush "rock on steel”

ALquezar's VSI Crusher

Crushing plant in Senegal

Alquezar will manufacture of quartzite crushing and classification plant in Senegal. This is a quarry for the production of concrete aggregates and asphalts, with 600 t/h capacity, incorporating a primary crushing stage, using a jaw crusher with 1400 x 1070 mm entry mouth. The secondary and tertiary crushing stages are carried out with three cone grinders, whilst the quaternary stage is comprised of a centrifugal grinder or vertical shaft impact crusher (VSI) model VA-2500.

The design of the plant, with its four crushing stages, guarantees good cubicity and the elimination of stones in the final product, providing top quality construction aggregates.

This is the second market covered by Talleres Alquezar in sub-Saharan Africa, after entering Angola a few years ago.

Washing Plant in the Panama Canal.

TALLERES ALQUEZAR has manufactured a washing plant for the GUPC basalt crushing quarry in the Panama Canal.

The plant is comprised of a wash screen, model TSL650, and a hydrocyclone sand recovery system. The washing trommel, model TSL650, is a machine that has been specifically designed for this project.  It has a supply capacity of 1000 tons per hour and is designed to admit a maximum feed size of 300 mm. For its part, the hydrocyclone sand recovery unit incorporates flat bottom cyclones to prevent excess fines in the final product.

The sale of this aggregate washing plant represents the extension of the commercial relationship between Alquezar and the contractor for the extension work on the third set of sluice gates of the Panama Canal: GUPC.

Impact crushers, BMTA series

The Alquezar impact grinding mills work with new kinematics, achieving special advantages in crushing and in their economy.

The feedstock enters laterally into the primary chamber, where the impact bars knock it against the specific wedges, where it is crushed. The sharp edges of the impact wedges penetrate the material, exerting a high pressure and bending stress, which enables us to crush larger-sized rocks than existing models on the market. The fragments of crushed material reach the second grinding stage, whilst the large sized materials recirculate again towards the primary chamber. The precrushed material passes to the third stage where it is submitted to the final grinding.

The typical design of the primary impact chamber creates the first crushing stage together with the impact elements. In this first stage, the impact elements have sharp edges, to be able to penetrate the rock better, due to the stress concentration placed on it. This system leads to considerable energy saving and guarantees less wear of the plates, so the production costs are also reduced. The second and third stage impact plates are mounted on hydraulically adjustable supports, so that we can adjust their distance from the rotor, depending on the material to be processed and on the material we want to obtain.

The impact grinding mill housing is covered with cast iron plates, with bolt or wedge fastenings accessible from outside the machine.

The rotor shaft is made of high quality forged steel, calculated to support the greatest strain. The transmission pulley can be placed on both sides of the shaft. The rotor is made of very robust welded elements, with wear-proof welding in the peripheral areas submitted to greater abrasion.

Maintenance is quick and easy thanks to the hydraulic housing opening system, which permits access to the impact bars, impact plates and wedges of the primary, secondary and tertiary phases.

Alquezar in the Panama Canal

Winner of the tender for two aggregate reclaiming plants for the work on the Third Set of Sluice Gates

Talleres Alquezar has won the tender for the design, manufacture and assembly of two aggregate reclaiming plants, for the construction work on the Third Set of Sluice Gates of the Panama Canal, carried out by the GUPC Consortium, and with the participation of the Spanish construction company, Sacyr.

The aggregate reclaiming plants, which will be located on the Atlantic and Pacific sides of the Canal, form a new system for loading, cooling, classifying and stockpiling aggregate that is carried out in real time according to the final concrete consumption demand.

This project amounts to almost 7 million dollars with 6 months' execution time.
