What types of Laboratory Sieve for Calcining Clay are available?

Laboratory Sieve for Calcining Clays are mainly divided into manual and electric types. There is also an ultrasonic model that can break up agglomerates and prevent clogging, suitable for fine sieving needs. Available in 2-8 layers, catering to various sieving needs.

Single-frame sieve: Consists of a single sieve frame and mesh, offering convenient operation. Primarily suitable for preliminary or coarse sieving where high precision is not required, it quickly separates large particles from calcined clay.

Test sieve: Typically composed of multiple stacked sieve frames with different apertures, driven by a vibrating motor to transmit vibration to the material within the sieve frame for sieving. Characterized by low noise, high efficiency, and high precision, it is widely used in laboratories for precise particle size analysis of calcined clay.

Ultrasonic test sieve: Based on a standard test sieve, it incorporates an ultrasonic system. Its unique sieving principle utilizes high-frequency electrical oscillations generated by an ultrasonic vibration power source, superimposed on the sieve surface and combined with low-frequency three-dimensional vibration, effectively solving the problems of fine powder agglomeration and mesh clogging caused by static electricity.

Striking sieve: Composed of a base, sieve fixtures, and transmission mechanism, it can be equipped with specialized clamps to hold multiple layers of test sieves. Its motor drives a gearbox via a synchronous belt, causing the main shaft to rotate. This, in turn, drives the eccentric wheel, push rod gear, and hammer to achieve material sieving. The impact sieve boasts high sieving efficiency, fast material discharge, thorough sieving, low maintenance costs, a simple structure, and standard bearings in rotating parts that are less prone to wear. It also offers the advantages of being environmentally friendly and clean.

Laboratory Sieve for Calcining Clay Operation Procedure

The Laboratory Sieve for Calcining Clay is driven by a vibration motor, which transmits the vibration to the sieve frame through a vibrating plate. The material forms a three-dimensional vibration trajectory on the sieve surface, and particles smaller than the sieve holes fall layer by layer, achieving particle size classification.

Pretreatment: The calcined clay sample is passed through a 2mm sieve to remove large particle impurities.

Sieve Frame Assembly: Stack sieve frames from bottom to top according to aperture size, from smallest to largest. Cover the top and install a receiving tray at the bottom.

Parameter Setting: Adjust the vibration time and amplitude according to the material characteristics.

Result Analysis: Weigh the residue mass of each sieve layer, calculate the cumulative sieve residue percentage, and plot the particle size distribution curve.

Laboratory Sieve for Calcining Clay Technical Parameters

How many grades can the Laboratory Sieve for Calcining Clay separate in one operation?

Our Laboratory Sieve for Calcining Clay can be configured with up to 8 sieve layers in a single operation, easily achieving simultaneous grading of 1-7 particle size grades, perfectly meeting the core needs of multi-size particle separation in scientific research experiments. The 8 sieve layers adopt a stacked design, arranged from top to bottom according to mesh size from coarse to fine. After the calcined clay sample is placed in the top layer, through high-frequency vibration, particles of different sizes are separated step by step along the sieve layers, obtaining multiple graded samples in one operation. A single grading operation only takes 5-15 minutes, far exceeding the efficiency of traditional manual sieving.

What material is most suitable for a Laboratory Sieve for Calcining Clay?

The material selection for a Laboratory Sieve for Calcining Clay needs to balance corrosion resistance, cleanliness, durability, and experimental safety. 304/316L stainless steel is the most suitable material. Calcined clay may retain trace amounts of acidic or alkaline components after high-temperature treatment, and laboratory settings require extremely high sample purity. Stainless steel effectively resists the corrosion of these components, preventing oxidation and rust that could contaminate samples, thus ensuring the accuracy of experimental data.

Laboratory Sieve for Calcining Clay Application Cases

We customize laboratory calcined clay sieve solutions for clients in different industries, providing suitable sieving equipment based on their production needs to support the smooth progress of scientific research and development in various fields.

New Cement-Based Material Development: When studying calcined clay as a supplementary cement-based material, laboratories need to precisely control its particle size distribution to analyze reactivity. An 8-layer laboratory calcined clay sieve with a 40-500 mesh gradient screen is used to separate seven particle size grades in a single pass. The equipment is constructed of 304 stainless steel to prevent corrosion from alkaline solutions, and high-frequency vibration ensures screening is completed within 15 minutes.

High-Dry-Strength Clay Formula Optimization: To develop crack-resistant clay formulas, ceramic companies' R&D centers need to control the particle size of calcined clay clinker and slurry. Laboratory calcined clay sieves are used, with a 250-mesh main sieve layer, supplemented by 200-mesh and 300-mesh auxiliary grading. A quick-release sieve design allows for rapid switching between sieve sizes.

Celadon-Colored Vitreous Clay Screening: Fine screening of calcined raw materials such as feldspar and kaolin is required. A combination of 80-200 mesh laboratory calcined clay sieves is used to accurately separate particles of different proportions, ensuring uniform mixing of components such as quartz and barium carbonate. The equipment's vibration parameters are adjustable to suit viscous materials, improving the uniformity of raw material mixing by 40% after screening.

How to Choose the Right Laboratory Sieve for Calcining Clay?

Choosing a laboratory sieve for calcining clay should be based on the core experimental objectives, comprehensively considering factors such as material compatibility, sieving accuracy, and ease of operation.

Material Selection: 304 or 316L stainless steel is preferred. For routine calcined clay sieving, 304 stainless steel is suitable due to its resistance to atmospheric corrosion, ease of cleaning, and compliance with food-grade and general scientific research hygiene requirements. If the experiment involves corrosive environments containing chloride ions or sulfates, or high-purity sample analysis, upgrading to 316L stainless steel is recommended.

Sieve Configuration: The mesh size should match the experimental grading objectives, with a common range of 40-500 mesh. For example, ceramic formulation optimization often requires 200-300 mesh fine sieving, geological material analysis may involve 40-80 mesh coarse grading, and the development of new cement-based materials requires 500 mesh ultra-fine separation. When purchasing, confirm that the sieve is a standard woven or perforated mesh, and prioritize a tensioned fixing structure.

Number of layers and sieve size: The number of layers determines the single-pass classification capability. An 8-layer sieve can achieve simultaneous separation of 7 grades, suitable for multi-gradient particle size analysis; if only 1-2 grades of separation are required, 3-5 layers are sufficient. The sieve diameter is recommended to be selected based on the sample volume per pass; 200-300mm is the mainstream laboratory size.

Vibration performance: A high-frequency vibration motor is required to generate a three-dimensional vibration trajectory, breaking up the electrostatic adsorption and agglomeration of calcined clay. For processing highly viscous calcined clay clinker, it is recommended to choose a model with an ultrasonic auxiliary system, which can improve sieving efficiency by more than 30%.

What is the price range for a Laboratory Sieve for Calcining Clay?

The price range for the Laboratory Sieve for Calcining Clay manufactured by DaHan Machinery is $20.00-$3,680.00. The price difference is mainly determined by the configuration and functions. Basic models, such as manual single-layer sieves, are less expensive and suitable for simple sieving needs.
