High Efficiency Low Vibration Screening Machine for Aggregate Processing
Product Introduction
The process of dividing fragmented materials into different particle sizes through one or several layers of screening surfaces is called sieving. A screening machine is a vibrating screening mechanical equipment that uses the relative motion between bulk materials and the screening surface to allow some particles to pass through the sieve holes, and divides materials such as sand, gravel, and crushed stone into different levels according to particle size. The screening process of a screening machine is generally continuous. After the screened raw materials are fed onto a screening machine (referred to as a sieve), materials smaller than the size of the sieve holes pass through the sieve holes and are called undersized products; Materials larger than the size of the sieve are continuously discharged from the sieve surface, known as products on the sieve.
Product Advantages
The working part of the drum screen is a cylindrical or conical screen cylinder, which is equipped with a rotating shaft along the axis of symmetry of the screen cylinder. The entire screen rotates around the axis of the cylinder, and the axis is generally installed at a small inclination angle. The conical surface sieve cylinder is installed horizontally, and the material is fed into the small end of the cylinder and lifted up with the rotation of the sieve cylinder. When it reaches a certain height, it falls down by gravity, and the fine grade material passes through the sieve holes on the working surface of the cylinder, while the coarse particle material is discharged from the other end of the cylinder. This continuous upward and downward movement achieves material screening. The rotational speed of the cylindrical screen is very low, the operation is stable, and the power balance is good. However, its sieve holes are prone to clogging and deformation, with low screening efficiency, small working area, and low productivity. It can be used for screening and dewatering coarse and medium materials. Mineral processing plants rarely use it as screening equipment.
Simple and easy to maintain structure
Some models have simple structures, easy to disassemble and replace screen surfaces, and are convenient for daily use and maintenance. And screening consumes less electricity per ton of material, saving operating costs.
Wide applicability
Can handle various materials such as moisture and viscosity, such as mesh screens suitable for damp materials, cylindrical screens have no requirements for high moisture and coal slurry, and are not sticky or blocked; It is also widely used in various fields such as mining, chemical industry, food, etc., to meet the needs of grading, impurity removal, filtration, dehydration, etc. Outstanding features, such as efficient and fast experimental screening machine, simple operation, accurate and reliable results; Fixed screens do not require power and have low cost; Roller screen does not block the screen; The resonance screen consumes less power, etc.
The screening machine utilizes the size and quality differences of materials, as well as the varying settling velocities of liquids. Small materials settle to the bottom of the tank while larger materials settle. A grading screen is a device that uses a spiral to push materials upwards and then mechanically screen them. It can filter the materials in the mill according to their grades, and finally screw larger materials into the feed inlet of the mill using a spiral blade to overflow the filtered small materials from the overflow pipe. The base of the grading screen is made of channel steel, and the body is welded from steel plates.
