Construction Process of Sand Production Line

Abstract：
1. Survey site The production of sand and gravel materials should be near, limited by resources and transportation conditions. Outside the safety scope of mine blasting, the production line should be built near by considering the transportation cost of raw materials and finished products. The object of investigation is mainly the geographic location and available resources of sand field, and the location of production line construction is roughly planned. The transportation distance of the selected site should not exceed 60 km in order to avoid additional transportation costs, and the shallow overburden of the mine, the conformity of physical and chemical indicators, stability, large reserves and convenient transportation are required. 2. Designing sand technological process Sand making process is designed to be three stages of crushing, i.e. primary crushing, medium crushing and fine crushing. The granite ore is transported to the unloading platform of the crushing workshop, and the granite with particle size less than 800 mm is transported by the vibrating feeder with sieving device; the granite with particle size less than 150 mm falls directly onto the belt conveyor and enters the primary stacking yard; the material with particle size larger than 150 mm is crushed by jaw crusher, and the crushed material is also transported to the primary stacking yard. After pre-screening by vibrating screen, materials less than 31.5mm are screened out directly, and materials with particle size larger than 31.5mm are crushed into impact crusher. After crushing and screening, materials with particle size larger than 31.5mm are further crushed into impact crusher. After crushing, materials with particle size larger than 31.5mm are screened into three layers of circular vibrating screen, which are divided into three specifications: 0-5mm, 5-13mm and 13-31.5mm. Material. The primary crushing equipment is jaw crusher, the intermediate crushing equipment is impact crusher and impact crusher, three crushers and screening workshop together constitute a closed-circuit production process. 3. Storage of finished products Three kinds of granite aggregates with different grain sizes are transported into three 2500 t round storehouses by belt after being qualified by crushing and screening.
