With the high-performance cooling system and automatic control system, it can achieve continuous material Continuous processing and discharge greatly improve production efficiency. Sand mills, also known as bead mills, are mainly used for wet grinding of chemical liquid products. According to the performance, the sand mill machine can be divided into horizontal sand mills, basket sand mills, and vertical sand mills. Among them, the most widely used are horizontal sand mills and vertical sand mills.http://www.cisuntech.com/sand-mill/

A clean room is a controlled environment where pollutants like dust, airborne microbes, and aerosol particles are filtered out in order to provide the cleanest area possible. Most cleanrooms are used for manufacturing products such as electronics, pharmaceutical products, and medical equipment. A cleanroom can be classified into different levels of contamination depending on the amount of particles allowed in the space, per cubic meter. Cleanrooms also control variables like temperature, air flow, and humidity.http://www.lhcleanroom.com/clean-room/

When using a Torpedo load box, the power sent to the load is turned into heat, so please follow the cooling recommendation of the load box – failure to do so may cause overheating which can lead to damage, both to the load box and to the amplifier.
