BESS™ Frequently Asked Questions (FAQ)

The recommended installation and production area for the PRS 800 semi-automatic hollow block machine is 2,500 m². Go to installation details.

A total of 7 personnel are required for the efficient operation of a semi-automatic plant: 1 machine operator, 1 mixer operator, 3 pallet transport staff, 1 pallet loading staff, and 1 raw material loading staff. Go to operational details.
Yes, vibrating machines, especially hollow block machines, can experience fractures and cracks in their frames due to the vibration and pressing systems they operate with. These machines undergo high levels of stress on their chassis. However, we minimize the impact of vibration on the frame by using special reinforcements and damping wedges in our machines. This ensures robust and long-lasting solutions for our users. Go to reinforced Special Design chassis.
The vibration system is essential for hollow block machines and is the most important factor affecting product quality. The most important features in vibration systems are easy installation and use, access to spare parts and service, and durability and reliability. For quality production and high performance, it is essential to consider these factors in the vibration system. Go to modular vibration system

The pallet dimensions for the PRS 800 are 95×115 cm, and they can be made from plastic, wood, or metal. In semi-automatic systems, the products are transported to the curing area using pallet carrying trolleys. Go to Pallet System

The most important factors affecting the performance of the machine’s hydraulic system are the quality and viscosity of the hydraulic oil, operating temperature, oil cleanliness and proper filtration, correct pressure and flow settings, high-quality components, proper installation, and regular maintenance. Each of these factors ensures the system operates efficiently and reliably. Go to Hydraulic System
