Legendary Performance Only A Muffin Monster® Can Provide
The 30K & 40K In-Line Muffin Monster sewage grinders have been providing peace of mind to treatment plant operators and collections managers for over 40 years. Wastewater professionals repeatedly turn to JWC’s Monster Grinders for the ultimate sludge grinder solution to cut down troublesome solids. It is ready for rags that can damage pumps, clog valves and foul treatment equipment – causing costly damage and excessive repairs.
The original 30K Muffin Monster is a workhorse of sludge grinder for biosolids processing systems. It covers flows from 450 to 2450 gpm (102-556 m3/hr). It has the ability to not only cut through rags and other solids in WAS and RAS but also precondition the sludge to give it a uniform consistency prior to digestion. The 30K units are also commonly installed within dry wells of pumps stations to protect pumps from solids found in the collections systems.
The 40K Muffin Monster is the even stronger sewage grinder offering with robust 2 ½” (64 mm) hex shafts, larger cutters. It also comes with a standard 10 HP (7.5 kW) drive motor. The 40K is for the highest solids loading environments like prisons and combined sewer pumps stations. Additionally as a sludge grinder it will excel in biosolids systems for larger treatment plants.
All dual shafted grinders have two rows of hardened steel cutters that rotate at slow speed and with incredibly high-torque. These will grind down large solids into small particles. 30K Monsters are also available with Wipes Ready® technologies which are specifically designed for shredding wipes and rags. Wipes Ready cutters shred rags and disposable wipes into small pieces that will not weave back together and form long ropes.
