Project introduction:

The purpose of this project is to use quicklime to make hydrated lime and use it as building materials for building exterior walls. The customer is a well-known local building materials supplier in Mumbai, India. We have not been involved in the production of raw materials before. Due to the good market environment, customers hope to have their own lime plant, reduce procurement costs, extend the industrial chain and realize long-term operation. Because they have been engaged in this industry for a long time, customers are familiar with Chinese lime manufacturers. After preliminary investigation, the customer considered bringing our factory into the other party's supplier system. At first, customers were not sure how much capacity they should build, and hesitated between 50 tons per day and 100 tons per day. To this end, we provided customers with the material list and cost list required for gypsum grinding of two kinds of output and sent them to customers. In this way, customers can have a rough estimate of the comprehensive cost of building factories with two kinds of output by combining the local raw material price, fuel price and land cost. After comprehensive comparison, the customer determined the production capacity at 100 tons per day. After collecting the basic information required for the project, we provided the customer with a detailed list of equipment and technical parameters. The customer highly recognized our technical strength and manufacturing capacity. At present, the project is in the detailed design stage, and the customer's technical team is confirming the technical details with us.

[Raw material] Limestone

[Fuel] Coal

[Production capacity] 100 tons per day

Project overview

Project address: Bombay, India

Product Name: Quick lime production line project

Production scale: 100 ton/day

Service scope:From the transportation and calcination of limestone raw materials to the process design of finished product storage and transportation system, electrical automation control system, plant planning, equipment supply, equipment installation and commissioning, after-sales training and other integrated technical services.

Project Solution

According to the information provided by the customer, the initial material of the customer is limestone, and the customer has a considerable amount of raw material reserves, which can fully meet the production needs.

The customer listened to the suggestions of our engineer team on the choice of using traditional long kiln and shaft kiln. Because the customer's site is sufficient and the customer's technical team is familiar with the traditional long kiln, it is decided to adopt the traditional long kiln process to produce limestone. According to the needs of customers, we provide customers with a complete set of equipment from material transportation to calcination and then grinding.

The materials with qualified particle size are fed quantitatively by the feeder, the stones are fed to the large inclination conveyor, and then sent to the screening building. The limestone with qualified particle size after screening is weighed and sent to the silo at the top of the preheater by the large inclination conveyor. Limestone calcination is composed of vertical preheater + rotary kiln + vertical cooler. The materials are introduced into the preheater body from the silo at the top of the preheater through the blanking chute. At the same time, the high-temperature flue gas from the rotary kiln preheats the materials to more than 1000 ℃, causing partial decomposition of limestone. The finished lime is discharged from the cooler and transported to each finished lime silo. After heat exchange with limestone in the preheater, the high-temperature flue gas generated by rotary kiln combustion is sent to the cyclone dust collector for primary dust collection. The dust with large particles is captured and then sent to the bag dust collector. After dust removal, it is discharged into the atmosphere through the high-temperature fan, and the dust concentration of the discharged gas is less than 30mg / m3. A cold air control system is set at the inlet of the dust collector to protect the dust collector.
