Parget Lime Production Line Process Description



The process described below will be applied for the Raw material feeding, storage and screening, calcination , crushing and storage unit, hydration.

Raw material feeding 1 , storage and screening unit is used to feed, store and control screening of raw material and feed it to the vertical kiln. Raw material with a fraction 40-80 mm is fed from feeding equipment to storage silos with belt conveyors. Instead of using long tranfer belt conveyor, it is also possible to use bucket elevator conveyor. Dedusting of the unit will be done by the dedusting filter and fans.

The raw material storage 2  and the screening unit mainly consist of the storage silo where the raw material is stored, the vibratory screen to screen and prepare the raw material according to the tolerances. Even if the material is brought with requested fractions, it may be crushed during transfer and storage. Therefore, it must be screened again, brought into requested tolerances, and then fed to the calcination unit.

The calcination unit 3  consists of the kiln, weighing and charging equipments, the vertical lime calcination kiln and the dedusting system. The prepared material will be weighed and fed to the skip bridge bucket and later with skipper winch it will be transfered to the calcination kiln. Depending on the final product, the raw material will be calcined under a certain temperature, pressure and time inside the kiln and later discharged by the help of the kiln discharging equipment to the discharge to belt conveyor. Meanwhile the necessary dedusting will be provided by the kiln dedusting system filter. The inside of vertical kiln is lined with different refractory materials. All air flow of the kiln is done and automaticly controled by traps, blowers and hydraulic system.

The calcined 4  lime will be discharged to the belt conveyor to be transferred to the lime handling, storage, crushing and filling unit. This unit is used to produce the calcined lime according to the final usage of the product. Particle size and their range will be specified by the Customer. The lime will be fed from the kiln to the crusher to be crushed and later to the vibratory screen in order to screen and classify to the requested particle sizes. Based on final product particle size,different types of crushers can be used as jaw crusher, hammer crusher and roller crusher. Eventually the lime with required fraction will be stored in the storage silos. Depending on Customer request, final product can be filled from storage silos to the open trucks, bulk carrier, big-bags etc.

Types of materials that would result ouf of the process:

1) Calcined lime is the material that we get after the calcination and the crushing to different fractions from 0-3 mm to 0-80 mm, any other fractions between is possible.

2) Grinded lime is a second type of product produced in lime plant. In order to produce this product, other grinding and classifing equipment are used. Also based on the request of the Customer, storage silos and different type of filling and packing equipment are used in order to deliver grinded lime to the final users.

3) The hydrated lime is another final product which can be produced on the plant supplied by Parget&Maerz. The hydrated lime is obtained as a result of the reaction during the mixing of calcined lime with water in „hydrator”. Feeding of the lime to the hydrator is done by dosing and weighing belt conveyor. After lime is hydrated it is fed for primary seperation and for the grinding. Separation is done by dynamic air separator and grinding is done by ball mill. After the grinding, hydrated lime is fed back to the seperator for reseparation to meet the required fraction. Eventually, hydrated lime is stored in the storage silos and filled or packed to bulk carrier, big bags, PP bags ets.
