Our company has developed a new type sand screening machine for rivers, reservoirs, coal yards of sand separation equipment. Mainly by the hull, shelves, reducer, conveyors, trommel, engine or motor components. This model is simple, affordable, and easy to operate. Tumble into sand screening machine, sand washing machine drum sieve, sieve shaker style sand machines. First, the working principle: The entire equipment from raw material storage hopper, raw material feed belt machine, flat screen set, finished stacking sand belts, abandoned stone out of the trough, etc., from the raw material into a large capacity loader after the device is powered operation hopper, raw material inputs via the feed belt to lay flat screen cylinder, rotating screen cylinder driven push blade material in the barrel, roll down the screen to form a raw material in the roll surface slippery artificial sand sieve effect, sieve out the finished sand Hopper finished by fall on the sand belt, the belt simultaneously upgrade was finished falling stockpiles, or directly into the hopper, the whole process is continuous and graded material clearly and accurately. Second, the device advantages: 1. Easy installation basis: because the entire device is box-shaped frame structure, you can just have a flat floor. Easy to clean surface hardening the best. 2. The overall height: In addition to the stockpile of finished feed belt, all systems are integrated within an overall framework, both the integrity of the device also permits moderate left space for maintenance and inspections. Convenience and safety. 3. disassembly transition is simple: to facilitate the construction of a high degree of integrity of the equipment stored on site or transitions transportation, dismantling parts only finished stacker belt, loosen the bottom bolts and hanging rope, the finished belt stuffed main frame underside can. 4. reliability: its core principle screening system using stirring mixer, raw stirring barrel roll by continuous spiral blade, pushing and mutual friction effect and high reliability between the role of a strong material. 5 flat screen cylinder roll set, the stream between the sieve sieve drum roll spiral blade over five laps, so full of sand tumbling repeated discrete screening. Unlike screening oblique oblique roll shaker screen or the size of the material caused by the mutual impact extrusion or aniseed care little material chattering caused by incomplete, mixing phenomenon. 6. Economy: ① hopper capacity of 8M, make reasonable arrangements loader master device (such as a mixing station) and feeding time sieve sand, avoiding loaders between different points on the material and raw materials frequently transposed, storage hopper mouth width greater than 3.2 meters, but also the loader easy feeding, reduce labor intensity. ② screen can be replaced pcs connection, replace or switch to a different mesh size sieve after easy wear. Third, the special features: 1. sieve barrel roll sanding device can sand block groups were broken, broken. 2. Roll mesh sieve surface cleaning device can be installed on the adhesion of self-cleaning to prevent clogging of sand mesh Note: This feature is particularly binomial especially building sand on the current prevailing market supply of sand moisture, soil containing rate than The phenomenon of high targeted results. Fourth, the technical parameters: Ground screening equipment, mechanical materials; mechanical drag walking; workload: 80-100 cubic meters / hour; Changsha rod hull models transport models gravel bar length (m) per hour stone wool equipped with power use Model clutch form WH two transport 6.7m 12m / 8m 80-100m3 1100-1105 2-3cm or 2-4cm WH three automatic clutch type conveyor 8.3m 12m / 8m / 6m 80-100m3 1100-1110 2-3cm-2-5cm automatic clutch type WH four transport 10.5 12m / 8m / 8m / 6m / 80-100m3 1100-1115 1-2 or 2-4 or 3-5 type automatic clutch
