Description

SYSTEM, DEVICE, AND PROCESS FOR CLASSIFICATION OF DIFFERENT MATERIALS [0002]

The present invention relates to various materials such as sand, minerals and the like containing a certain amount of harmful materials through continuous or batch processes integrated with high efficiency in order to improve lower production cost and final product of consumers in the materials and minerals industry to users. Lt; RTI ID = 0.0 > and / or < / RTI > More particularly, the present invention relates to systems, processes, and devices for classifying various materials.

An advantage of the present invention is to provide a unique process for the removal of hazardous materials from the supply and production of high quality products graded with high efficiency while recycling most of the process water in the circuit for reuse. This can greatly reduce the requirement for fresh water.

The system, process, and apparatus of the present invention can be used in a variety of applications including manufactured sand, crusher dust, river sand, glass grade sand & foundry sand, But are not limited to, a wide range of minerals such as bauxite, manganese, coal, lignite, chromite and the like.

Current classification system:

Currently, bucket wheel recovery systems are used for wet classification equipment such as wet screens, but in some applications hydrocyclones are used for spiral classifiers. ) Is used. The recovery of water for wet classification is an important point. Currently, sophisticated systems such as traditional Thickeners, Settling ponds / dykes, Water tanks, etc. are being used for water recovery.

Disadvantages of current technology:

Currently, classification using the above-mentioned equipment is isolation and does not provide an integrated solution to the user. For example, a wet screen, a bucket wheel, or a spiral sorter cuts the material to a very coarse size, and the defective material includes a large amount of usable material. In addition, this material must be processed using a different system. In addition, there is no solution for the reuse of process water, and the user must reuse process water, install a separate water recovery system, or accept a large waste of important natural resources.

While hydrocyclones have been successfully used for efficient size separation in other industries over the past few years, hydrocyclones alone do not provide a complete solution for users. The hydrocyclone discharges the slurry-like material, and therefore the user must devise a separate facility for dewatering the hydrocyclone underflow to recover a good material. Next, the hydrocyclone requires an enormous amount of water to function properly, and it discharges a large amount of water together with the defective product. Again, there is no solution to the reuse of process water, and the user must install a separate water recovery system to reuse the process water and accept a large waste of important natural resources.

The present invention provides a complete waste management and recycling system with a single integrated compact design that allows for the efficient reclassification of materials with the maximum number of process waters for reuse and the extraction of graded products from other raw materials. It is the first technology to integrate. One example of the use of the present invention is the production of high quality sand and of size to be used on a daily basis by the construction industry. The present invention will greatly improve the final product quality, such as concrete work, plastering, and the like. Other examples increase productivity and add value to industries such as steelmaking and steelmaking plants that can significantly reduce the cost of production due to the efficient removal of silica and alumina present in ore as a harmful material.

The basic purpose of the present invention is to solve the drawbacks / deficiencies of the known art.

In accordance with the present invention, a single integrated compact system for the extraction of micro-graded particles is provided and this system is also capable of efficient classification of the material with a maximum recovery of process water for reuse by a complete waste management and recycling system Do.

In one embodiment, a waste management and recycling system provides a system for the classification of various materials and / or minerals and the extraction of micro-graded particles with variable size at the maximum recovery of process water.

The system comprises:

a. An integrated feed system for processing materials and / or minerals, the system comprising a feed hopper, a feeder and a belt conveyor, wherein the feed system is adapted to feed material to the feed boot (01) and the split cleansing screen (02) Adapted, supply system;

b. A split cleansing screen (02) to obtain dehydrated and ejected particles in the form of a slurry; A hydrocyclone device (04); Integrated Product Conveyor 1 (06); And a sump (03);

c. A sizing system comprising a hydrocyclone apparatus (04), wherein pressure is applied via a slurry pump (05) to remove the remaining particles and remove ultrafine particles; And

d. (08) located on the side of the main slurry tank (09) together with the scraping mechanism (12) and the surrounding purified water tank (11) to obtain the purified water recycle process and to discharge the sludge to the desired sludge treatment area Waste management system.

As used herein, "process water for reuse" means that the water used by the apparatus during the fractionation process is substantially recovered from the waste slurry produced by the system. At this time, the recovered water is reused by the system for other sorting operations, thereby reducing the requirement for fresh water.

The presence of very fine particles and clay at high ratios adversely affects the demand for workability, water demand and factors. The presence of very fine particles (less than 75 microns) in natural sand is not permitted. Typically, in this size range, the particles are in the form of clay and clay that must be removed and removed during concrete production. Also, in the case of artificial / manufactured sand, during the production of such manufactured sand particles, the occurrence of less than 75 microns is very high and must be eliminated. This proved that if very fine particles were limited to 6%, water demand, cement demand would be reduced and workability improved at the same time. The present invention can produce precise sized and reinforced high quality sand by effectively reducing the amount of undesirable very fine material while ensuring that available sand is not lost as waste.

The device has the ability to classify a wide range of sizes from 0.045 microns to 10 millimeters. For example, in a sand application, the device may be divided into 0.075 millimeters to 2.36 millimeters, 0.075 millimeters to 5 millimeters, or 0.045 millimeters to 10 millimeters, depending on the user's requirements.

In one embodiment, a process is provided for the classification of various materials and / or minerals having varying sizes. This process is described below.

The materials and / or minerals to be treated are provided in an integrated feed system (denoted by 00) consisting of a feed hopper, a feeder and a belt conveyor to aid material handling equipment such as a loader / truck. The supply system carries the material to the supply booth (labeled 01) for onward discharge to a portion of the split cleaning screen (labeled 02) in the dry state. Next, an appropriate amount of water is added to the split cleansing screen through the booster pump (labeled 13) to clean the coarse particles. The sorted coarse particles are then dehydrated in a split cleansing screen and transferred to an integrated product conveyor 1 (labeled 06) for stockpiling.

Next, the water recovered from the split cleansing screen is discharged in slurry form to the sump below (denoted 03) along with the fine particles.

The slurry is pumped to a set of hydron-cyclone (s) (labeled 04) at a specified pressure through a slurry pump (labeled 05) and a particular type of pipeline. The hydron-cyclone (s) receives the mixture from the sump, slurry pump, and removes rejects by removing super-fine particles such as debris. At the same time, sized particles are recovered to the full extent as a single product.

Next, the sized micro-usable particles are discharged in slurry form with the hydron cyclone (s) along with water and fed to the other part of the split cleansing screen for the dewatering process. A split cleansing screen dehydrates useful purified fine particles and discharges them to the associated product conveyor 2 (denoted as 07) for stockpiling. The water recovered from the split cleansing screen with some ultrafine particles is discharged to the sump for recirculation. The super-fine particles form a circulating load in the circuit.

The waste slurry from the hydron cyclone (s) is supplied via a wear resistant pipe operation to a pre-fabricated branding chamber (indicated at 08) located on the side of the main slurry tank (denoted as 09) of the water recovery system. This is also the point at which the polymer electrolyte is injected into the slurry through the Flocculants Dosing Tank (denoted 10). The injected sludge travels under a baffle that is designed to promote laminar flow in the transfer pipe at the center of the main slurry tank. The material flow is slower and promotes the flow of the layer to the main slurry tank for downward fixation of the sludge.

Next, the purified water flows from the manufactured peripheral channel to the outside of the main slurry tank and is discharged into a Peripheral Clean Water Tank (denoted by 11) which is fused in the water recovery system. Next, the constants from the surrounding water tank are circulated to the split cleansing screen and the sump through the booster pump for recirculation to the system for sorting operations.

The settled sludge at the bottom of the main slurry tank follows the required consistency and is discharged with the aid of a scraping mechanism (designated 12) that moves the sludge towards the discharge point.

The sludge is then discharged to the desired sludge treatment zone by pneumatically actuated valves actuated by a factory installed and orientedly tested evacuation pump (designated 14), and an air compressor (designated 15) do.

Programmable Logic Control The motor control panel (labeled 16) controls the entire process system according to the desired parameters.

The present invention is fully preassembled and electrically wired through extensive testing performed prior to shipment from the factory to ensure minimum intervention required by installation and commissioning engineers.
