Standard test sieves adopt vertical vibration motors as the vibration source. The vibration motor drives the upper vibrating tray, which transfers vibration to the sieve frames placed on top of the tray. Material particles smaller than the mesh apertures pass through the target sieve frame into the layer below. Through this layered screening process, each test sieve retains materials of uniform particle size, realizing separation of particles with different sizes, determining the particle size composition of materials, and achieving effective filtration, grading and screening.Application IndustriesWidely used in R&D, production, laboratories, quality inspection departments and universities across metallurgy, chemical, pharmaceutical, powder, building materials, national defense, geology, petroleum, agriculture, food and other industries.Operation PrecautionsAdjust the operation time as required. The first two digits of the time relay represent minutes, and the last two represent seconds. Set the reading of the time relay to your desired duration.Place the test sieve frames inside the equipment and tighten the nuts before starting the machine.The test sieve shaker will shut down automatically once the running time reaches the preset value; take out the sieve frames carefully afterwards.

Stainless steel test sieving mesh is widely used for screening, filtration, protection and decoration, covering industries including mining, petroleum, chemical, food, pharmaceutical, machinery manufacturing, architectural decoration, electronics, aerospace and more.Now let Green Energy’s editor share the precautions for using stainless steel sieving mesh.Properly control the aperture size of stainless steel sieve plates and avoid improper tightening of bolts. Ensure the stainless steel sieve plates match the screening machine to reduce tension plate deformation and control the fitting degree between stainless steel sieve plates and tensioning parts; otherwise, the service life of the sieve plates will be greatly shortened. In addition, the amplitude of stainless steel sieve plates should be properly regulated.To guarantee stable working efficiency of stainless steel sieving mesh, operate it strictly in accordance with the manufacturer’s instructions in daily use so as to extend its service life.

In the building materials industry, using vitrified microbeads as lightweight aggregate can improve the workability, fluidity and self-strength of mortar, lower material shrinkage rate, enhance the overall performance of finished products and cut comprehensive production costs. Different industrial applications require drastically different particle sizes of the material, so vitrified microbeads are classified into Grade 1, Grade 2, Grade 3 and other grades based on particle size. A complete vitrified microbead production line consists of crushers, screening machines, conveyors and other major equipment. After vitrified microbeads are crushed to below 10 mm, fine screening equipment is required for grading. Common mesh sizes for grading vitrified microbeads include 20 mesh, 50 mesh, 70 mesh, 90 mesh, 120 mesh and 180 mesh. The grading accuracy must be controlled within ±10%, which sets high standards for the precision of vibrating screening equipment.

Wet materials have poor fluidity and tend to clog mesh screens, resulting in unsatisfactory screening results, which has long been a troublesome problem for customers. Some people try tapping the screen manually, yet the effect remains unsatisfactory. Different types of wet materials processed by sieve shakers lead to varying degrees of mesh clogging. Here are several practical tips to help users select proper solutions to resolve clogging issues:Increase the exciting force of the vibration motor to raise the frequency of three-dimensional movement of materials on the screen surface.Adopt wet screening: add water to dilute materials and improve their fluidity.

Recently, many users have consulted me and asked, "Can tapping test sieves be used for material testing in laboratories?" Today I will give a unified answer in this article: Yes.The tapping test sieve is a commonly used small tapping vibrating sieve machine. It serves as a testing and analysis sieve for coal quality testing, as well as experimental and analytical work in geology, metallurgy, chemical industry, scientific research, cement and many other industrial sectors. It can be regarded as screening equipment specially designed for laboratory use.So what are the advantages of tapping test sieves as dedicated laboratory screening equipment?Three Major Advantages of Tapping Test SievesMature structure, long service life and low maintenance costThe two gears of the tapping sieve are not in direct contact, resulting in slight wear. The synchronous belt and gears feature good adaptability, delivering a longer service life; only the synchronous belt needs to be replaced during maintenance. Meanwhile, the eccentric wheel assembly adopts an integrated structure for accurate and convenient reinstallation. Standard bearings are used for rotating parts, which are resistant to wear, easy to replace and low-cost, greatly reducing maintenance difficulty and expenses.Fast transmission with timing functionThe transmission mode driven by gears and synchronous belts provides an accurate speed ratio without speed loss, enabling high screening efficiency. Its unique design allows the tapping sieve to generate both reciprocating motion and tapping vibration during operation, effectively preventing mesh clogging. It features fast material discharge, thorough screening and high efficiency. In addition, the tapping sieve is equipped with a timing function to guarantee consistent test results. The power controller supports preset working time and automatic shutdown, ensuring uniform test data for production batches.Low energy consumption, clean and hygienicThe unique transmission structure adopted by the new-type tapping sieve cuts maintenance costs and effectively protects the working environment, meeting users' requirements for cleanliness.
