密封化验制样粉碎机是实验室用来制取实验样品的*后一道工序，是一种新型化验制样粉碎设备，专门用于粉碎具有一定硬度的金属或非金属物质。如：煤炭、矿石、水泥、化工产品以及硬度较大的中药等。该产品采用压杆式（或螺旋式）防松动装置，轻便可靠，全密封式，无粉尘外溢，无需排风除尘。高频震动研磨，粉碎效率高，粒度均匀，不混样，无需筛分缩分，运行稳定、安全可靠、使用寿命长、制样速度快、安装简易，使用方便，可根据样量选用不同品种。

Sealing test sample pulverizer is the last working procedure laboratory used to prepare samples, is a new type of test sample grinding equipment, specially used for grinding metal or non-metal materials with certain hardness. Such as: coal, ore, cement, chemical products and a larger hardness of traditional Chinese medicine. This product uses the pressure bar (or spiral) anti loosening device, convenient ａnd reliable, fully sealed, no dust, no dust removing. High frequency vibration grinding, high crushing efficiency, particle size uniformity, no mixing, no need to screen division, stable operation, safety ａnd reliability, long service life, fast sample preparation, simple installation, convenient use, ａnd can be used in different varieties depending on the sample volume. Widely used in crushing sample preparation in the laboratory of coal, metallurgy, mine, electric power, building materials, chemical industry, medicine ａnd scientific research departments.
