Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its light weight after processing. Perlite is widly used to produce light weight wall panel due to its light weight feature. More and more wall panel facotry will adopt perlite for their final finished wall panel products. It is very necessary study perlite in more details. Perlite boulders with fireweed in foreground. Perlite softens when it reaches temperatures of 850–900 °C (1560-1650 °F). Water trapped in the structure of the material vaporises and escapes, and this causes the expansion of the material to 7–16 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles. Unexpanded ("raw") perlite has a bulk density around 1100 kg/m3 (1.1...

Servo block machine control is the technical improvement of traditional frequency conversion control of block machine. The servo block machine control system adopts the most advanced vibration mode recognized in the industry - motion controller drives servo motor to realize vibration. At present, S.L Machinery adopts a vector closed-loop vibration synchronization system to ensure the stable speed and accurate control accuracy of the motor under load changes. By integrating synchronous control algorithm and variable phase angle algorithm, automatic compensation is realized to achieve the function of consistent speed and consistent start and stop. By changing the phase angle to control the exciting force, the amplitude and frequency can be adjusted simultaneously. The start and stop time is 0.3s, and the start acceleration time is the fastest in the same industry. The system has the characteristics of stable vibration, small amplitude, fast acceleration and stepless speed regulation. &nb...

The full automatic control of the wall panel machine production line is realized by the high performance digital logic control system on the general console, and each system can be controlled independently. The whole system program has linkage, interlocking, state display, fault diagnosis and data input through computer. It has the normal working function of the remote fault diagnosis and the recovery control system. The PLC centralized control system can not only use the automatic control production line, but also control the work of each part of the production line manually. The core controller adopts SIEMENS PLC. The signal transmission is stable and fast. The PLC centralized control system can store data and programs of various products at the same time, and record daily output automatically, which is convenient for production planning, raw material consumption and output statistics. S.L Machinery makes perfect construction, professionally focus on light weight wall panel machine, ...

S.L Machinery founded in 1993,committing to global environmental protection and pursuing for the achievement of perfect buildings ,has acquired more than 150 patents and a number of scientific research achievements.Our block making machines with servo vibration system has many advantages such as high efficiency,lower energy consumption and easy to maintain etc..which has attracted many domestic and overseas customers' interest and focus.   The block machine with servo vibration system can produce blocks with higher strength.Besides,there are  much more advantages for the servo block machine than the normal block making machines.     Firstly,the servo vibration system consists of a servo controller,servo drivers and servo motors.The vibration table is composed of a vibration box and a vibration board.Before pressing,the servo vibration system is turned on and the vibration table runs at a lower frequency.When the raw material distribution finished,the vibra...
