Sand and stone production line is mainly composed of vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor and centrally electronic control and the designed yield is generally 50-800t/h.
Powder grinding production line is widely used for making powders in the industries of mine, power plant, chemistry, building material, metallurgy, refractory, desulfuration in power station, pitch mixing station and highway and the granularity of the final products can be adjusted in the range of 20-3250 Mesh.
Sand making plant is a professional production line to produce building sand and stone. It can make a variety of rock, sand and gravel, river pebbles into various size construction sand, sandy uniform particle size
Ceramsite production line or ceramsite sand production line belongs to building material equipment. The raw materials of ceramsite sand are mainly some solid wastes like bauxite, shale, city waste, gangue, biological sludge, river sediment and fly ash etc.
Compound fertilizer production line is widely applied to produce compound fertilizer and the capacity ranges from 5,000-200,000 tons/year. It can granulate NPK fertilizer, DAP and other materials into compound fertilizer particles in one processing line.
The flotation separation process also called the flotation separating production line, realizes the mineral particle separation based on the working principle of different physical and chemical properties of the minerals.
Great energy conservation, wide adjustment range, low noise and little dust
