BAIONI WASHING EQUIPMENT EXPANDS IN AMERICA

American quarrying company has partnered with Baioni to deliver a state-of-the-art wet processing plant, currently under installation, featuring crushing and screening process, to produce the following fractions: 0-5, 5-10, 10-20 mm

Two Baioni mirror-crushing and screening plants are being tested in two different sand and gravel quarries in Central America with a capacity of 100 tonnes per hour. Baioni has designed and supplied the new plants to a private investor who has made its local staff available to start the line. Baioni took care of the assembly, the supervision and the start-up that is taking place in these days. The project was created to respond to an urgent need to produce suitable, quality aggregates for the production of concrete, to be employed in infrastructure and construction works. Baioni met the client during a workshop at a local fair, he turned to Baioni to study the project together, he knew the name Baioni and had visited the neighboring working plants some time ago to understand their functionality and structural quality. After several months of project design, the contract was concluded: two equal plants in composition and production, which will be started soon in two different sites.

The feed material is taken directly in the quarry, with a feed size of 650 mm and, after two crushing stages, is washed and finally screened out into four fractions: 0-5, 5-10, 10-20 mm.

In the primary crushing phase, a unit consisting of a primary jaw crusher mod. BP 110/70, an apron feeder and a wobbler feeder mod. GD 90/8 capable of effectively pre-selecting and cleaning the coarse material. In the secondary crushing phase, a reversible hammer mill mod. MIL 1000SP with fixed hammers entirely made of DUR, highly reliable for the type of material to be processed. The material passes through an accurate washing process to remove all impurities, for this reason a washing and recovery station has been implemented for the separation of the silt and the recovery of sands with characteristics of various granulometry composed of a group with hydrocyclone mod. GRF and dewatering screen.

Cyclone technology involves the use of centrifugal force to idify materials rather than gravity. The aim of the sand recovery group with hydrocyclone is to treat sand mixed with water (slurry) and to return dry sand. Slimes release the overflow in the upper part of the cyclone with waste water, to be then sent to a water management system. The fraction of sand leaves the lower part of the cyclone, drained and ready for storage. Product yield is maximized and operating costs are reduced. Water treatment plants are becoming increasingly vital equipment in quarries as their benefits outweigh the initial investment; the ROI on a Baioni BaiWash system is generally six to nine months. The innovative washing system improves productivity by bringing together one-of-a-kind washing technology with on-site training and service after the installation to ensure an operation's entire crew can quickly and capably achieve the best results from the washing system.
