Raymond is a stone production line manufacturer, which can tailor the production line equipment for customers to meet different needs.

Stone production line technology

The big stones are sent to the jaw crusher by the vibrating feeder through the silo for coarse crushing, and the coarse crushed stones are sent to the impact crusher by the belt conveyor for further crushing. Stones from fine crusher were sent to a vibrating screen for screening, and several stones with different specifications were screened out. The stone that meets the requirements of particles is sent to the finished product pile by the finished product belt conveyor, and the stone that does not meet the requirements of particles is sent back to the impact crusher by the belt conveyor to be crushed again, forming a closed cycle. The granularity of finished products can be combined and combined according to the needs of users.

Stone process flow chart is shown on the right.

Introduction of production line: Introduction of active lime production line: Qualified limestone is stored in silo, lifted by hoist and transported to the silo at the top of preheater. The feed rate is controlled by the upper and lower level gauges, and then the limestone is evenly distributed to each chamber of the preheater through the discharge pipe. Limestone is heated to about 900℃ by kiln flue gas at 1 150℃ in the preheater, and about 30% is decomposed. The limestone is pushed into the rotary kiln by a hydraulic push rod, and sintered and decomposed into CaO and CO2 in the rotary kiln. The decomposed materials enter the cooler, which is cooled to below 100℃ by the blown cold air and discharged. The lime coming out of the cooler is sent to the finished lime bin by vibrating feeder, chain bucket conveyor, bucket elevator and belt conveyor. Production capacity: 800,000-300,000 tons/year
