Quick lime powder, also known as calcium oxide (CaO), plays a fundamental role in numerous industrial processes. From steel manufacturing to construction, agriculture, chemicals, and waste treatment, the versatility of quick lime makes it indispensable to modern industry. In Khinvsar, Rajasthan, a region abundant in high-purity limestone deposits, quick lime manufacturing has become a major economic and industrial driver.
At Rama Lime Industries, we are committed to delivering high-quality quick lime powder that meets the most demanding industrial standards. With decades of expertise and an unwavering focus on innovation and sustainability, we have established ourselves as a trusted leader in the field.
Abundance of High-Grade Limestone
Khinvsar sits atop one of India’s richest belts of carbonate-rich limestone, the key raw material for lime production. The region’s geological consistency ensures the raw limestone has low silica and high calcium content—ideal for producing reactive and pure quick lime.
Proximity to Major Industrial Markets
With its strategic location in Rajasthan, Khinvsar provides easy access to industrial hubs like Delhi NCR, Gujarat, Maharashtra, and Punjab. This geographical proximity reduces transport costs and ensures fast supply to industries across northern and western India.
1. Sourcing and Selection of Raw Limestone
We begin with systematic selection of limestone, ensuring only high-CaCO₃ content stone is chosen. This guarantees low impurity levels and results in superior quality quick lime.
2. Crushing and Screening
The raw limestone is crushed and screened using automated systems to obtain uniform particle size. This consistency is crucial for uniform calcination.
3. Calcination in Modern Vertical Shaft Kilns
Our production utilizes advanced vertical shaft kilns that operate at temperatures above 900°C. These energy-efficient kilns provide consistent temperature control, resulting in high-reactivity quick lime powder.
4. Hydration and Sieving (Optional)
For clients requiring hydrated lime, we process quick lime through carefully controlled hydration and sieving to produce fine-grained, dust-free powder.
5. Packaging and Delivery
The final product is packed in moisture-proof HDPE bags or jumbo bags depending on client requirements. Our in-house logistics team ensures timely and damage-free delivery across India.
Steel and Metallurgical Industry
Quick lime is essential for desulfurization, dephosphorization, and slag formation in steel production. Our high-reactivity lime accelerates chemical reactions and improves metallurgical performance.
Construction and Building Materials
Used in soil stabilization, AAC block manufacturing, and plaster formulations, quick lime improves compressive strength, workability, and durability of building materials.
Chemical Industry
In calcium carbide, citric acid, and caustic soda manufacturing, quick lime acts as a reactive precursor. We provide lime tailored to precise chemical purity standards.
Water and Wastewater Treatment
Calcium oxide helps neutralize acidic waste, remove heavy metals, and adjust pH balance. Municipal and industrial clients rely on our lime for environmental compliance.
Sugar Industry
Used in sulphitation and clarification, quick lime ensures high recovery and purity of sugar juice during processing.
Paper and Pulp Industry
Quick lime is used for causticizing in the chemical recovery cycle and bleaching processes, helping manufacturers reduce chemical usage and improve efficiency.
