1.Accurate rotation,good consistency
2.Long life,low maintenance cost
3.High screening efficiency,clean
Usable sieve diameter
Putting sieve layers
2,Principle of work
Motor driven gear through the timing belt drive to the spindle, after the spindle speed by the gear required rotational speed, spindle driven eccentric to reciprocating motion skateboarding do to drive installed in the slide tray in the two groups both large and small mesh sieve test rock around the same time, push-rod gear driven spindle rotation speed after the ejector hit top gear by cam mandrel, mandrel to shoot down slap hammer test screen cover, making test sieve, sieve in the sub-sample of the material back and forth and up and down vibration , so that test is less than mesh sieve screen surface material particles into the lower screening test sieve, so layers of screening, so that each layer within the test screen, leaving only the same size material. To achieve the separation of different particle size and to determine the size distribution of this material.
(1) driving accuracy, consistency, good: As the use of gear driven timing belt transmission, speed than accuracy, does not produce the off-speed phenomena in general Triangle (Triangle 3% of the off rate), so that each time under the same time screening exercise in line (gear transmission ratio accuracy of 99.99%), while equipment installation a digital timer, set a good time to automatically shut down to ensure consistency of testing or production requirements.
(2) long service life, maintenance, maintenance cost is low: Since there is no direct contact with the two gears do not wear contacts synchronous and gear, good adaptability and long service life, maintenance, just replace the timing belt at the same time eccentric group adopts a holistic approach again easy to install and accurate, rotating part of the use of bearings (standard parts), easy to wear, low cost, easy to replace. Reduces the maintenance technical requirements and costs.
(3) The screening efficiency is high: This screening approach to screening at the same time with Rattling two kinds of movement back and forth, and do not plug the sieve surface and lower material fast and thorough screening.
Mainly used in diamond material such as high value of screening accurate, demanding the production; abrasive industry
Widely used in metallurgical, powder, chemical, pharmaceutical, building materials, geology, feed, national defense department's research and production, lab and quality inspection room, granular, powder material of particle size structure, and sundry amount of standard test screening, filter, standard test screening test.
