The production line main equipment provided by Echo Equipment, now the production line capacity is fine mechanism sand 150-250 tons per hour.

Product application: supply high-speed rail

Process flow

Pebble material goes into European hydraulic jaw crusher PEW760 for coarse crushing, and get into single cylinder hydraulic cone crusher HST250 for second crushing through belt conveyor, and then enter into control bunker, in addition to begain sand making less than 40mm with impact crusher VSI5X-1145 via belt conveyor, finallly fine sand product size is 0-5mm, now the quality and price is fully comparable to the high quality natural river sand.

Equipment configuration advantage

1. European hydraulic jaw crusher: jaw assembly with high quality steel castings, heavy eccentric shaft by forging blank processing, which make machine has excellent reliability, more durable, besides, equipment is provided with a wedge discharge opening adjusting device,which is more simple, safe and fast than the traditional gasket adjustment. The crushing chamber adopts symmetrical "V" shaped structure, which makes actual feed inlet width inlet is in line with nominal feed inlet width.

2. Single cylinder hydraulic cone crusher: high production efficiency and strong bearing capacity, low operation cost and maintenance. Automatic control of production process, multi cavity adapt to a variety of process requirements.

3. Hydraulic centrifugal impact crusher: impact crusher is arranged on the top of the hydraulic lifting device for maintenance. Impact crusher with thin oil lubrication station equipment don not need to manually refuel per shift and reduce labor costs. Impact crusher using intelligent touch screen control display can observe equipment working process in real time. Impact crusher has low production and high efficiency cost, and then large capacity, furthermore, the mechanism sand is quality , which can replace natural river sand, moreover, the production line has been free to change gravel and shape function according to needs.
